What is Green Power and what makes it Different from Other Energy Sources?

For those aware of the different environmental movements taking place to protect the environment, EnviroCitizen.org has found that green power is not necessary a new concept. Green power is a power option provided by some companies that cater to green energy. Green power poses a lot of benefits, including environmental and cost benefits. However, it is important not to confuse green power with other sources of energy. This is because green power doesn’t have the same source of power generation. Some energy sources also don’t have environmental and cost benefits.

Green power is a subset of the available renewable energy. This is actually defined as the electricity produced from different sources such as wind, solar, biogas, biomass, geothermal and other small low-impact hydroelectric sources. Many people purchase green energy because they want to protect the environment from the harmful impacts of other types of energy.

The sources of green power generate electricity that is superior and far better than conventional power resources and technologies. Green power produces zero greenhouse emissions. It is controlled by EPA and its resources are required to have been operational within the last 12 years. This is to back up and support the new developments as well as for the growth of renewable energy.

If you think green power is the best way to go green, then you’ve got to request this service from your energy company. Prior to doing so, it is important that you do some research first. With green power being generated through the use of different sources, some sources are actually better than others.

Unlike conventional power supplies which require the utilization, combustion and carbon emission of fossil fuels as well as uranium nuclear fission, green power is purely natural. This means it poses less harm to the environment.

Conventional power has a negative impact on air pollution and greenhouse emissions which are produced from the combustion of fossil fuels. Nuclear power generation is actually more positive in such a way that it doesn’t emit greenhouse gases during the generation of power. Thus, it still requires the process of mining, extraction and radioactive waste storage which can cause long-term harm to the environment. For those truly concerned about the environment, EnviroCitizen.org believes it’s better to shift to green power whenever possible and to choose to forgo conventional power and inefficient energy practices.

Tower Wind Turbine – a unique know-how for wind power generation

Tower Wind Turbine – a unique know-how for wind power generation

Historical background in brief

People have been using wind power from the time immemorial.  
Originally they learnt to transform kinetic energy of wind stream into mechanical one. There appeared lots of different wind mills making men’s life much easier in those times.
An idea of a wind turbine for electric power generation using wind power started up around 100 years ago.
Inventors created wide range of various types of wind power generator designs:
– by axis (horizontal, vertical, inclined); 
– by number of blades (one, two, three and more);
– by capacity (from tens W to several MW);
– by blade design, by generator design etc.
But in an attempt to raise WTG’s capacity inventors faced new problems: 
1. Mechanical properties of materials modern wind generators are made of become serious constraints due to the generators’ size and dynamic loads they bear. Further expanding capacity (size) of wind generators calls for application of the latest which means more expensive materials which is reflected on the rise of prices of generated power that are rather high even without that.
2. Wind generators of higher capacity require higher wind speeds. Nowadays it becomes more and more difficult to find areas for construction of wind farms but people require more and more power.  
Today wind energy market grows up to 30% annually. But with wind power generation enthusiasts along there lately appear more and more skeptics. Wind power generation being clean and using renewable sources has number of substantial disadvantages: low quality of generated power, TV and radio signals interference, bad sound influence on fauna and need in additional reserve power generating capacities of traditional design etc.
More and more people being worried about negative trends in wind energy generation reasonably ask such questions as: What are the prospects of wind power generation? Will wind power generation take economically significant place in world economy? Will the investments in wind power generation be fruitful etc.?
World oil and gas market situation stimulates development of power generation using renewable sources. High price and low quality of such electric power does not make estimates of wind energy generation prospects more optimistic.
People need new reliable sources of electric power meeting following requirements of today’s life:
1. Low price of generated power
2. High quality of generated power
3. Power output should satisfy constantly growing demand
4. Clean power generation
One of the alternative power generation solutions meeting most of the requirements mentioned above is presented below.

Everything new is long forgotten old

Wind energy generation is fundamentally based on two elements: energy source (wind) and energy receiver (wind turbine generator).
Since first steps in wind power development and until now inventors have been improving energy receiver but energy source (wind) has been considered to be a gift of nature that is beyond any control. 
In many ways it reflected in various disadvantages of modern wind power generation.
In technical system “wind – wind generator” both elements are equally important. 
Only control over all elements of a system allows reaching highest working efficiency. 
Improving energy receiver they dropped an idea of controlling wind for no need. But in vain! 
Level of modern technical development allows arrangement of quite an effective control over such systems. 
But wind power generation went the other way. At present all wind generators operate on the basis of the same principal: collecting energy of incoming air flow. 
We decided to develop a brand new technical system which could allow controlling both energy source as well as energy receiver. Using men’s experience and knowledge in construction and operation of wind generators we can sufficiently increase their working efficiency by controlling of air flow parameters (energy source). 
One of the results of our long year researches and tests is a tower wind turbine. It gives a possibility more or less to control all the elements of the system “wind – wind generator”. 
Tower wind turbine consists of the following main elements: energy collecting device, generator, energy concentration device and control system.

]]>

Energy collecting device is designed as a vertical cylinder the walls of which are framed of profiles making end-to-end channels connecting outer side of the cylinder with its inner vertical channel (input convergent channels). Their aim is to “catch” incoming air flow and turn it vertically up along the vertical axis of the unit and to send it to generator blades.

Generator with blades is places inside the energy concentrating apparatus. Generator transforms kinetic energy of wind into electrical one. 
Energy concentrating device is contractually designed as a vertical hollow tower inside dimensions of which converge in the central part where the generator is placed. Inner part of the tower is continuation of the vertical inner channel of the energy collecting device. Such design allows concentration of kinetic energy of wind on generator blades.
Control system (is not shown in the picture) provides timely opening of convergent channels of the tower from the side of the incoming wind and closing of all the other convergent channels.

What are principal differences between tower wind turbine and conventional wind generators, transforming energy of incoming air flow? 
1. It allows controlling wind energy concentrating on generator blades. 
2. Rotor blades do not need to be “tuned” to wind. Vertical axis generator is fixed in the upper part of the unit. Wind is “tuned” to the generator itself owing to design of the energy collecting device.
3. Speed of wind rises significantly when it reaches generator blades. Design of the energy concentrating device allows raising wind speed in the inner vertical channel of the unit increasing its capacity accordingly.  
Experimental tests of the unit models in aerodynamic tunnel showed growth of power output of the generator placed inside the tower more than 4 times, and at low wind speeds – more than 10 times.  
To prove received results a 100:1 scale production prototype was constructed. Diagram of
comparative tests (similar to laboratory tests diagram). 
Analysis of received results shows significant efficiency growth of the generator placed inside the concentrating tower in comparison with wind generators of conventional design: 
– Wind initial velocity is 2 times lower;
– Rated wind speed is 2 times lower;
– Utilization factor of installed equipment can reach 0,6…0,7 (was calculated) ;
– Power output is 2-3 times higher;
– 5 times more energy is collected from wind stream area unit at all wind speed ranges, at low speeds – more than 10 times;
– Area of allotted land per unit of rated capacity of the TWT is the lowest among all types of generation.
Tower wind turbine concentrates wind energy on generator blades like a lens collecting sun light into the focus.
Design features of the TWT allow elimination of various disadvantages of conventional wind generators:
1. Noises and radiation harmful for people that can appear during operation of the generator of the TWT do not leave the tower as generator and blades are placed inside of it. Modern materials allow reduction and absorption of harmful noises and vibrations. For the same reason generator and blades of the TWT do not interfere TV and radio signals.  
2. TWT can not cause any injuries for birds. To prevent birds from getting onto generator blades one may place protective nets at the entry to the convergent channels. To avoid birds clashing into the TWT at night its outer surface is lighted. It could also improve tower’s appearance.

Future Outlook

Technical characteristics of the TWT surpass all the modern convention wind turbine generators using incoming air flow.

Tower wind turbine can be a worthy substitute for conventional wind turbine generators.
– TWT can work at low wind speeds. 
– TWT allows reaching larger power output. 
– TWT’s effectiveness is in no way lower than that of conventional power stations using carbon fuel such as: gas, coal, black and crude oil and its ecological cleanness has no analogues.  
– TWT becomes very effective in areas with low wind speeds. 
– Area of allotted land per unit of rated capacity of the TWT is the lowest among all types of generation
– Due to its compactness TWT can become an autonomous self-sufficient power source.  

Tower wind turbines today are world wind power generation of tomorrow: low production cost and high quality of ecologically clean energy.

Renewable Energy

Renewable Energy

Renewable energy

Renewable energy is energy generated from natural resources—such as sunlight, wind, rain, tides, and geothermal heat—which are renewable (naturally replenished). In 2006, about 18% of global final energy consumption came from renewables, with 13% coming from traditional biomass, such as wood-burning. Hydroelectricity was the next largest renewable source, providing 3% of global energy consumption and 15% of global electricity generation.

Wind power is growing at the rate of 30 percent annually, with a worldwide installed capacity of 121,000 megawatts (MW) in 2008, and is widely used in European countries and the United States. The annual manufacturing output of the photovoltaics industry reached 6,900 MW in 2008, and photovoltaic (PV) power stations are popular in Germany and Spain. Solar thermal power stations operate in the USA and Spain, and the largest of these is the 354 MW SEGS power plant in the Mojave Desert. The world’s largest geothermal power installation is The Geysers in California, with a rated capacity of 750 MW. Brazil has one of the largest renewable energy programs in the world, involving production of ethanol fuel from sugar cane, and ethanol now provides 18 percent of the country’s automotive fuel. Ethanol fuel is also widely available in the USA.

While most renewable energy projects and production is large-scale, renewable technologies are also suited to small off-grid applications, sometimes in rural and remote areas, where energy is often crucial in human development. Kenya has the world’s highest household solar ownership rate with roughly 30,000 small (20–100 watt) solar power systems sold per year.

Some renewable-energy technologies are criticized for being intermittent or unsightly, yet the renewable-energy market continues to grow. Climate-change concerns, coupled with high oil prices, peak oil, and increasing government support, are driving increasing renewable-energy legislation, incentives and commercialization. New government spending, regulation and policies should help the industry weather the 2009 economic crisis better than many other sectors.

Main forms/sources of renewable energy

The majority of renewable energy technologies are powered by the sun. The Earth-Atmosphere system is in equilibrium such that heat radiation into space is equal to incoming solar radiation, the resulting level of energy within the Earth-Atmosphere system can roughly be described as the Earth’s “climate.” The hydrosphere (water) absorbs a major fraction of the incoming radiation. Most radiation is absorbed at low latitudes around the equator, but this energy is dissipated around the globe in the form of winds and ocean currents. Wave motion may play a role in the process of transferring mechanical energy between the atmosphere and the ocean through wind stress. Solar energy is also responsible for the distribution of precipitation which is tapped by hydroelectric projects, and for the growth of plants used to create biofuels.

Renewable energy flows involve natural phenomena such as sunlight, wind, tides and geothermal heat, as the International Energy Agency explains:

Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources.

Each of these sources has unique characteristics which influence how and where they are used.

Wind power

Vestas V80 wind turbines

Airflows can be used to run wind turbines. Modern wind turbines range from around 600 kW to 5 MW of rated power, although turbines with rated output of 1.5–3 MW have become the most common for commercial use; the power output of a turbine is a function of the cube of the wind speed, so as wind speed increases, power output increases dramatically. Areas where winds are stronger and more constant, such as offshore and high altitude sites, are preferred locations for wind farms. Typical capacity factors are 20-40%, with values at the upper end of the range in particularly favourable sites.

Globally, the long-term technical potential of wind energy is believed to be five times total current global energy production, or 40 times current electricity demand. This could require large amounts of land to be used for wind turbines, particularly in areas of higher wind resources. Offshore resources experience mean wind speeds of ~90% greater than that of land, so offshore resources could contribute substantially more energy. This number could also increase with higher altitude ground-based or airborne wind turbines.

Wind power is renewable and produces no greenhouse gases during operation, such as carbon dioxide and methane.

Water power

Energy in water (in the form of kinetic energy, temperature differences or salinity gradients) can be harnessed and used. Since water is about 800 times denser than air, even a slow flowing stream of water, or moderate sea swell, can yield considerable amounts of energy.

One of 3 Pelamis P-750 Ocean Wave Power machines in the harbor of Peniche, Portugal

There are many forms of water energy:

Hydroelectric energy is a term usually reserved for large-scale hydroelectric dams. Examples are the Grand Coulee Dam in Washington State and the Akosombo Dam in Ghana. Micro hydro systems are hydroelectric power installations that typically produce up to 100 kW of power. They are often used in water rich areas as a Remote Area Power Supply (RAPS). There are many of these installations around the world, including several delivering around 50 kW in the Solomon Islands. Damless hydro systems derive kinetic energy from rivers and oceans without using a dam. Ocean energy describes all the technologies to harness energy from the ocean and the sea: Marine current power. Similar to tidal stream power, uses the kinetic energy of marine currents Ocean thermal energy conversion (OTEC) uses the temperature difference between the warmer surface of the ocean and the colder lower recesses. To this end, it employs a cyclic heat engine. OTEC has not been field-tested on a large scale. Tidal power captures energy from the tides. Wave power uses the energy in waves. Wave power machines usually take the form of floating or neutrally buoyant structures which move relative to one another or to a fixed point. Osmotic power or salinity gradient power, is the energy retrieved from the difference in the salt concentration between seawater and river water. Reverse electrodialysis (PRO) is in the research and testing phase. Vortex power is generated by placing obstacles in rivers in order to cause the formation of vortices which can then be tapped for energy. Solar energy

Monocrystalline solar cell

In this context, “solar energy” refers to energy that is collected from sunlight. Solar energy can be applied in many ways, including to:

Generate electricity using photovoltaic solar cells. Generate electricity using concentrating solar power. Generate electricity by heating trapped air which rotates turbines in a Solar updraft tower. Generate hydrogen using photoelectrochemical cells. Heat water or air for domestic hot water and space heating needs using solar-thermal panels. Heat buildings, directly, through passive solar building design. Heat foodstuffs, through solar ovens. Solar air conditioning Biofuel

Plants use photosynthesis to grow and produce biomass. Also known as biomatter, biomass can be used directly as fuel or to produce biofuels. Agriculturally produced biomass fuels, such as biodiesel, ethanol and bagasse (often a by-product of sugar cane cultivation) can be burned in internal combustion engines or boilers. Typically biofuel is burned to release its stored chemical energy. Research into more efficient methods of converting biofuels and other fuels into electricity utilizing fuel cells is an area of very active work.

Liquid biofuel Information on pump, California.

Liquid biofuel is usually either a bioalcohol such as ethanol fuel or an oil such as biodiesel or straight vegetable oil. Biodiesel can be used in modern diesel vehicles with little or no modification to the engine. It can be made from waste and virgin vegetable and animal oils and fats (lipids). Virgin vegetable oils can be used in modified diesel engines. In fact the diesel engine was originally designed to run on vegetable oil rather than fossil fuel. A major benefit of biodiesel use is the reduction in net CO2 emissions, since all the carbon emitted was recently captured during the growing phase of the biomass. The use of biodiesel also reduces emission of carbon monoxide and other pollutants by 20 to 40%.

In some areas corn, cornstalks, sugarbeets, sugar cane, and switchgrasses are grown specifically to produce ethanol (also known as grain alcohol) a liquid which can be used in internal combustion engines and fuel cells. Ethanol is being phased into the current energy infrastructure. E85 is a fuel composed of 85% ethanol and 15% gasoline that is sold to consumers. Biobutanol is being developed as an alternative to bioethanol.

Another source of biofuel is sweet sorghum. It produces both food and fuel from the same crop. Some studies have shown that the crop is net energy positive ie. it produces more energy than is consumed in its production and utilization.

Solid biomass Sugar cane residue can be used as a biofuel

Solid biomass is most commonly used directly as a combustible fuel, producing 10-20 MJ/kg of heat. Its forms and sources include wood fuel, the biogenic portion of municipal solid waste, or the unused portion of field crops. Field crops may or may not be grown intentionally as an energy crop, and the remaining plant byproduct used as a fuel. Most types of biomass contain energy. Even cow manure still contains two-thirds of the original energy consumed by the cow. Energy harvesting via a bioreactor is a cost-effective solution to the waste disposal issues faced by the dairy farmer, and can produce enough biogas to run a farm.

With current technology, it is not ideally suited for use as a transportation fuel. Most transportation vehicles require power sources with high power density, such as that provided by internal combustion engines. These engines generally require clean burning fuels, which are generally in liquid form, and to a lesser extent, compressed gaseous phase. Liquids are more portable because they can have a high energy density, and they can be pumped, which makes handling easier.

Non-transportation applications can usually tolerate the low power-density of external combustion engines, that can run directly on less-expensive solid biomass fuel, for combined heat and power. One type of biomass is wood, which has been used for millennia. Two billion people currently cook every day, and heat their homes in the winter by burning biomass, which is a major contributor to man-made climate change global warming. The black soot that is being carried from Asia to polar ice caps is causing them to melt faster in the summer. In the 19th century, wood-fired steam engines were common, contributing significantly to industrial revolution unhealthy air pollution. Coal is a form of biomass that has been compressed over millennia to produce a non-renewable, highly-polluting fossil fuel.

Wood and its byproducts can now be converted through processes such as gasification into biofuels such as woodgas, biogas, methanol or ethanol fuel; although further development may be required to make these methods affordable and practical. Sugar cane residue, wheat chaff, corn cobs and other plant matter can be, and are, burned quite successfully. The net carbon dioxide emissions that are added to the atmosphere by this process are only from the fossil fuel that was consumed to plant, fertilize, harvest and transport the biomass.

Processes to harvest biomass from short-rotation trees like poplars and willows and perennial grasses such as switchgrass, phalaris, and miscanthus, require less frequent cultivation and less nitrogen than do typical annual crops. Pelletizing miscanthus and burning it to generate electricity is being studied and may be economically viable.

Biogas

Biogas can easily be produced from current waste streams, such as paper production, sugar production, sewage, animal waste and so forth. These various waste streams have to be slurried together and allowed to naturally ferment, producing methane gas. This can be done by converting current sewage plants into biogas plants. When a biogas plant has extracted all the methane it can, the remains are sometimes more suitable as fertilizer than the original biomass.

Alternatively biogas can be produced via advanced waste processing systems such as mechanical biological treatment. These systems recover the recyclable elements of household waste and process the biodegradable fraction in anaerobic digesters.

Renewable natural gas is a biogas which has been upgraded to a quality similar to natural gas. By upgrading the quality to that of natural gas, it becomes possible to distribute the gas to the mass market via the existing gas grid.

Geothermal energy

Krafla Geothermal Station in northeast Iceland

Geothermal energy is energy obtained by tapping the heat of the earth itself, both from kilometers deep into the Earth’s crust in some places of the globe or from some meters in geothermal heat pump in all the places of the planet . It is expensive to build a power station but operating costs are low resulting in low energy costs for suitable sites. Ultimately, this energy derives from heat in the Earth’s core.

Three types of power plants are used to generate power from geothermal energy: dry steam, flash, and binary. Dry steam plants take steam out of fractures in the ground and use it to directly drive a turbine that spins a generator. Flash plants take hot water, usually at temperatures over 200 °C, out of the ground, and allows it to boil as it rises to the surface then separates the steam phase in steam/water separators and then runs the steam through a turbine. In binary plants, the hot water flows through heat exchangers, boiling an organic fluid that spins the turbine. The condensed steam and remaining geothermal fluid from all three types of plants are injected back into the hot rock to pick up more heat.

The geothermal energy from the core of the Earth is closer to the surface in some areas than in others. Where hot underground steam or water can be tapped and brought to the surface it may be used to generate electricity. Such geothermal power sources exist in certain geologically unstable parts of the world such as Chile, Iceland, New Zealand, United States, the Philippines and Italy. The two most prominent areas for this in the United States are in the Yellowstone basin and in northern California. Iceland produced 170 MW geothermal power and heated 86% of all houses in the year 2000 through geothermal energy. Some 8000 MW of capacity is operational in total.

There is also the potential to generate geothermal energy from hot dry rocks. Holes at least 3 km deep are drilled into the earth. Some of these holes pump water into the earth, while other holes pump hot water out. The heat resource consists of hot underground radiogenic granite rocks, which heat up when there is enough sediment between the rock and the earths surface. Several companies in Australia are exploring this technology.

Wind Power Equipment Manufacturing Industry Gradually Became Popular

Wind Power Equipment Manufacturing Industry Gradually Became Popular

Global energy shortages, rising oil prices, are forcing the world to find new sources of energy, including wind energy development is in many countries attached great importance to fields.

Survey shows that countries in the world not only in wind energy development and utilization of investment will continue to grow, and wind power equipment manufacturing industry will become the most popular in many countries the economic field, the corresponding size of the market will also increase dramatically.

While the world’s wind power generation last year, growth is large, but regional development is uneven, compared with other regions, Europe’s fastest growing wind power generation, in which Germany’s wind generating capacity of 1.03 megawatts, accounting for wind power generation in Europe about half capacity.

United States: their technical and equipment superiority

According to reports, the U.S. will use its technology and equipment advantages, so that wind power to play a more important role. The U.S. Department of Energy’s new energy management agencies have recently pointed out that, despite the current U.S. wind power accounted for only 1.5% of the proportion of electricity production, but the proportion in 2010, up 9.5% in 2020, could exceed 15%.

In recent years, the U.S. wind power generation technology has been a major improvement, mainly in: improvement of the blades of wind power generation equipment design, the widespread use of wind sensors, using automatic control systems, reducing manpower and lowering costs.

According to reports, the U.S. government is vigorously promoting wind power equipment manufacturing industry, making it an important foundation for the 21st century, the energy equipment industry. It is predicted that by 2010, the United States and the European wind power generation equipment upgrades will occur climax, there will be a large number of old fashioned wind power generation equipment has been eliminated and that wind power generation equipment market is very optimistic about the prospects.

Europe: entering the fast growing period of

In many European countries, people can see the tall towers of wind power generation equipment. They are like a super utility poles, quietly standing roadside, river, farmland, or hill. In recent years, European countries continue to promote the development of wind energy, wind energy utilization in some countries have begun to take shape.

Germany is the development and use of wind energy earlier state, since the last century, 90 years, Germany has established a total of 6600 wind power plants. The German government plans in the future will be an annual growth rate of 30% annual growth of more than 1,000 MW of wind power.

Denmark near the North Sea, is a country of windy, but also pioneered the development of wind power stations country.

& nbsp20 Over the years, Denmark has been in the use of wind energy in the leading position. Since the 20th century, 90 years, especially in recent 10 years, the Danish wind power capacity growth rates of more than 30%.

In recent years, wind power equipment manufacturing in Europe has entered a period of rapid growth. In addition to Germany, the Netherlands, Denmark, Sweden, France, Norway, Finland, Italy and Spain and other countries have also introduced a 5 year, 10 wind power penetration plans.

Asia, Latin America: behind North America and Western Europe

In Asia is now clear that the development of wind power behind North America and Western Europe. However, the international energy experts believe that this does not mean that wind power equipment market in Asia will do nothing. The Japanese Government has repeatedly reiterated the importance of the development of renewable energy sources, only from 1999 to 2003 in Japan and Western Europe, related to wind energy development technology cooperation projects reached 55. In addition, Asia, India, China, Pakistan, Thailand, Indonesia, South Korea and the Philippines and other countries, most recently five years in wind energy development and application of investment also increased. India over the past three years, the World Bank 455 million U.S. dollars loan for the construction of wind power equipment manufacturing plant and importing technology.

Latin America is also the world’s wind energy development and utilization in recent years, rapid progress in the area. In the region of Brazil, Argentina, Chile, Venezuela and Paraguay, in the past five years, investment in wind energy in the development of an annual growth of 18.5%, higher than Asia.

The world’s wind power equipment manufacturing industry to strengthen international cooperation

The wave of the global economy is driving the world’s wind power equipment manufacturing industry to strengthen international cooperation to accelerate the commercialization of new technologies and open up market space. For example, in Europe the Netherlands, Denmark, Sweden and Norway, the four countries to work together are being developed for residential solar a combination of wind power equipment in order to take full advantage of the sun and wind power.

Another noteworthy feature is that many large enterprises and multinational companies have begun through mergers, cooperation and other means sought to monopolize the world of wind power equipment market. The growing number of countries are to focus on wind power equipment manufacturing industry to support the emerging industries, to promote the country’s economic revitalization. According to the analysis, the international wind power equipment manufacturing industry and related fields, market prospect is very broad, wind power equipment manufacturing industry rapid development not only enables enterprises to obtain the benefits of good will for people to create many employment opportunities.

Renewable Energy’s Bright Future: Green Energy’s Pros and Cons

Renewable Energy’s Bright Future: Green Energy’s Pros and Cons

Renewable Energy’s Bright Future: Green Energy’s Pros and Cons

This article is brought to you by the green web hosting provider.

Recent international focus on safe energy underscores the need for reevaluating all energy alternatives, particularly those that are clean and renewable. Because although the global economy is coming out of a recent recession, oil prices are climbing and the demand for alternative renewable sources is consistently growing. Indeed, the alternative energy market is one of the few markets that has seen substantial growth during the recent recession of the last two years. One thing is clear; the need for more efficient use of electricity with the integration of renewable energy sources is present.

Smart Grid and the Integration of Renewable Energy Sources

The Smart Grid is a Department of Energy (DOE) supported project that involves an integrated system of mixed distributed resources to increase the penetration of renewable energy – such as hydro, wind, solar, wind and geothermal, while delivering improved efficiency and reliability. These and other distributed resources will be fully integrated into the new smart, electrical grid.

What is Renewable Energy?

Renewable energy sources are sources of energy that are constantly replenished. These include energy from water, wind, the sun, geothermal sources, and biomass sources such as energy crops. In comparison, fuels such as coal, oil, and natural gas are non-renewable. Once a deposit of these fuels is depleted it cannot be replenished – a replacement source must be found instead. In the United States, both renewable and non-renewable energy sources are used to generate electricity, power vehicles, and provide heating, cooling, and light. While renewable energy is generally more expensive than conventionally produced supplies, alternative power helps to reduce pollution and to conserve fossil fuels. “People sometimes get caught up in cost-effectiveness,” said Paul Torcellini, a senior engineer at the DOE’s National Renewable Energy Laboratory (NREL) in Golden, Colorado. “But it can be a question of values and what we spend our money on.”

For comparison purposes, we will explore a few of the different sources of renewable energy:

Hydropower

WHAT IT IS:

Hydropower refers to the use of water to generate electricity. Water is the most common renewable source of energy in the United States today. Hydroelectric power doesn’t necessarily require a large dam – some hydroelectric power plants just use a small canal to channel the river water through a turbine. Other uses of hydropower include water-cooled chiller and power systems.

PROS:

Hydropower is a renewable and non-polluting energy source without any greenhouse gas discharge and no toxic waste production.

CONS:

Where dams are built in order to utilize hydropower, the cost can be substantial. Also, the unnatural block in the river’s system disturbs natural fish migratory and spawning patterns.

THE FUTURE:

Hydropower energy sources should experience strong development in the coming decades because of their non-polluting nature and significant unexploited potential.

Wind Power

WHAT IT IS:

Wind power refers to the use of modern wind turbines that are used to generate electricity, either for individual use or for contribution to a utility power grid. The power in wind increases rapidly with its speed, which means that locating windmills in areas of strong winds is critical. The strongest winds in the United States tend to be in Alaska, the western United States, and the Appalachians. Wind power currently supplies about 1% of United States electricity needs, but capacity is expanding rapidly.

PROS:

Wind power is plentiful, renewable and relatively affordable. Wind power does not produce emissions.

CONS:

Wind power produces power intermittently.

THE FUTURE:

Renewable energy companies are producing technology that is becoming more attractive and although this is to be expected with climbing oil prices, the demand for alternative energy was climbing even two years ago when oil prices were low. In 2008, oil prices were lower than they are today, yet 2008 was a market year for wind energy installation. One out of two wind turbines in the United States are GE built. The painful recession that occurred in the last few years did not slow the growth of alternative renewable energy. Wind energy business is taking off with more wind energy installed in 2008 than had been installed in the previous twenty years.

Solar Power

WHAT IT IS:

Solar power refers to the use of the sun’s energy to provide heat, light, hot water, electricity, and even cooling, for homes, businesses, and industry. Despite sunlight’s significant potential for supplying energy, solar power provides less than 1% of U.S. energy needs. This percentage is expected to increase with the development of new and more efficient solar technologies.

PROS:

Solar power gives off no pollution, however, during the manufacturing, transportation and installation of these goods there is pollution produced.

CONS:

A big drawback of solar power is the large investment needed in order to purchase solar cells. Currently, prices of highly efficient solar cells can be above 00, and some applications may need more than one. This makes the initial installation of solar panels very expensive. Homeowners have been reluctant to embrace solar panel installations on their homes because the panels can be aesthetically unpleasing and because the technology may require puncturing an existing roof and bolting on metal supports, which can void the roof’s warranty.

THE FUTURE:

Solar panel roof tiles consist of grids of raised black cells that, up until now, have usually come in the form of large clunky rectangular panels that either stand alone, or must be bolted onto a roof. The market potential for aesthetically appealing solar panels that can be integrated into the roof of one’s house is great. Read more at Sunslates (external link).

Geothermal Power

WHAT IT IS:

Geothermal power refers to the use of natural sources of heat inside the Earth to produce heat or electricity. Currently, most geothermal power is generated using steam or hot water from underground. Geothermal power generation produces few emissions and the power source is continuously available.

PROS:

Geothermal power is efficient and cost effective. This power source leads to savings. Additionally, this is around 70% cheaper than heating a home using electric heating, oil or liquefied petroleum gas.

CONS:

Geothermal power is not a do-it-yourself project because of the technical knowledge and machinery required for design and installation. The design alone may already be complicated to do and the pipe connection process requires proper training and the right tools.

THE FUTURE:

For individual household applications, geothermal heat pumps pass air through a pipe below ground that stays a constant 50 to 60 degrees, heating in the winter and cooling in the summer, saving tremendous amounts on utility costs in the process. Although geothermal stocks lost significant value during the recent recession, it is anticipated that Federal incentives will lure private capital to the sector, allowing financing to go through for new projects.

Renewable, Green Energy: Future Growth

Assumptions about world oil prices are not the only important factor that underscores the need for renewable energy use and consolidation. It is projected that by the year 2030, the demand for electricity in the United States will jump by 30%. And with projected oil prices, as well as concern about the environmental impacts of fossil fuel use and strong government incentives for increasing the use of renewable energy, the prospects for renewable energy use will likely increase worldwide.

Translation Services for the Renewable Energy Sector

Renewable energy is energy which comes from renewable (naturally replenished) resources. Renewable sources of energy are wind power, solar power (thermal, photovoltaic and concentrated), hydro- electric power, tidal power, geothermal energy and biofuel and biomass energy.

Renewable energy technologies offer significant advantages over conventional ones for meeting energy needs worldwide.

With the steadily increasing demand for renewable energy worldwide, it has never been more important to find a translation company with a familiarity in the terminology of the renewable energy sector and a proven expertise in the field. A translation company that has capacity to handle large scale multi-language projects and meet tight deadlines.

 

Global challenge

With the increasing worldwide demand for energy, the development of renewable energy has become one of the most important issues facing the global community nowadays.

World summits and conferences are being held all over the globe in an attempt to ensure that future energy demands are met in a more sustainable way by using renewable sources of energy.

For example, the European Union sets ambitious targets for all member states, such that the EU will reach a 20% share of energy from renewable sources by year 2020.

The success of such a global challenge is based on the ability of all international shareholders and stakeholders to intercommunicate and interact.

Language barriers can pose a great obstacle to the efficient communication and cooperation of all interested parties.

Based on this international symbiosis comes the need for professional translation services providers with expertise in the field of renewable energy.

 

Logistics/transference of energy

Most renewable energy projects are large-scale and they cross national borders.

For example Niagara Falls provides energy for both Canada and the USA.

The same applies to the HydroQuebec project. Successful professional translations allow different language groups and cultures to communicate effectively with each other and share the benefits of renewable energy.

 

Renewable energy production

While most of the management communication can be carried out in English, there are vertical communication streams that contribute to the production process. The workers involved in the renewable energy sector must clearly understand what they are being asked to do and how to ensure a safe working process.

One badly translated line in a document can send out the wrong message, possibly resulting in life-threatening situations for the workers in the renewable energy industry.

Residential Wind Generators, Are They Right For Me?

Residential Wind Generators, Are They Right For Me?

Residential Wind Generators, Are they right for me?

Residential wind generators are becoming more accessible to a greater number of people than ever before. More people want to know, are they right for me?

There are many things to take into consideration when reviewing wind power, the first being the availability of wind in your area.

Once you know if your average wind speed is favorable, the next step is to see if wind power generators are allowed under your zoning. You may need a building permit.

If you have neighbors close by you may want to talk to them about the aspect of a home wind power generator in the neighborhood. Some may be thrilled to see a proactive approach to green power. Others may have concerns about residential wind generators that need to be addressed.

The average wind speed in your area is a good starting point but there are many other variables that will affect the performance of a home wind power generator.

The topography of your location greatly affects your wind availability. Even in a high average wind speed area, if you live in a valley or on the lee ward side of a bluff your wind power generators performance will be disappointing.

On the other hand someone in an area of low average wind speed could do quite well with residential wind generators if they are on a hilltop or the windblown side of a bluff or ridge. Some light wind residential wind generators claim startup speeds as low as four MPH.

The average wind speed in an area can vary greatly through the seasons. At our location in northwestern Illinois, our average wind speed in summer is class 2. In winter when all the crops are harvested and the leaves are off the trees we often reach class 4. Light wind residential wind generators should do quite well in our area.

Because of all the variables involved, and the expense of the installation, site surveys are required to more accurately assess the capabilities for residential wind generators at a given site. This is the only way to accurately gauge the size of wind power generators needed.

Under unfavorable conditions a residential wind generator may still produce power, but the return on investment will take much longer. Under such circumstances a smaller less expensive home wind power generator may be the best option.

The entry point for a home wind power generator has become quite reasonable. There are now small light wind residential wind generators that can be purchased for three to four hundred dollars.

For larger wind power generators half the cost of installation can be the tower. The advantage of small wind power generators is the ability to be mounted on existing structures such as roof tops. Also in many cases no special equipment other than a ladder are required to install.

Many home owners are capable of making the home wind power generator installation themselves. The amount of energy each individual can produce may only be a portion of their needs, but because of the low cost and ease of installment more people can own a home wind power generator.

State and Federal rebate and tax incentives can reduce the equipment and labor costs of an installation as much as 30%. This is a very good stimulus to get people involved residential wind generators.

Because more people can become involved, the impact of small residential wind generators could be significant.

Most return on investment schedules are based on current energy costs. Because energy costs are likely to rise annually the actual return on investment from residential wind generators may be much sooner than predicted.

To find federal and state tax and rebate programs for residential wind generators visit http://dsireusa.org/

The American Wind Energy Association is an outstanding resource that can help you find the average wind speed for your geographic location. They also have a wealth of information about small residential wind generators. You can access their website at http://awea.org/ .

Ed Eubanks is a DIY green power enthusiast on a mission to bring power generation to a more personal level. He has a strong Mechanical-Electrical background from working 28 years in the US steel industry. His mission is to promote personal power generation to the masses. Residential wind generators are a good entry point for people to start generating a portion of their enegy needs.
