Affordable Solar & Wind

The Greener Power - Wind Power Electricity

There are different sources of electricity. Most of our electricity today comes from power plants in which power generators are fueled by things like coal and petroleum.  Alternatives like solar power and wind power are available as well and increasing in popularity due to the fact they are known as clean and renewable sources.  The different sources of energy fit the different needs of the consumers. Each energy source has its own advantages and disadvantages that may determine its availability and feasibility in any given application.

Electric power from wind is an example of clean energy. When generating electricity from wind, there are no harmful chemicals or gases emitted during the process. As a matter of fact, most environmentalists push for the implementation of more wind turbines to power communities and provide them with their basic need for electricity. Just imagine a world with clean sources of energy: it would be wind-powered, smokeless, odorless, and environmentally friendly.

To understand the basic operation of converting wind to electricity, one needs to understand the generator itself. A generator is an electrical machine that converts kinetic energy to electrical energy. There are a lot of articles on the internet that discuss in detail how they operate. As an electric generator, it needs a "prime mover" in order to operate and produce electricity. The prime mover is actually any mechanical force that rotates a certain part of the generator.  There was a period in history when people manually rotated the generator for power production. This of course was very impractical. We need other sources of mechanical force to act as the prime mover of the generator. In the mid 1900's, engineers began to design generators with wind as their prime movers. Later in 1970's, the first practical wind powered generator was in operation, and so began the era of wind-powered electricity.

Wind power generation is most ideally located where there is a strong wind almost all the day, every day.  The most common locations are beaches and coastal areas where there is a sea breeze during the daytime and land breeze during the night time. With enough wind power, electricity generation can go as high as several kilowatts to megawatts, enough to provide power to a small to medium sized community. Islands with wind generators located on the mainland can provide their own power.  Submarine power cables are very impractical and dangerous at the same time. So by using wind energy, the island can still have electricity. Archipelagoes will benefit this kind of electric power generation.

There are many advantages that wind energy offers. It answers both the problems of decreasing sources of fossil fuels and the need for a clean energy sources. For years, it remained a minority in providing electric power to communities, but as technology and the demand for clean, renewable energy sources increase, we will likely find it used more and more.

How to Compare Energy Costs

[Guardian] Dutch scientists generate electricity with kites

What should we replace fossil fuel with in the Power Generation industry?

The US Depertment of Energy says we currently have a generating capacity of about 1 trillion watts. About 70% of that is currently coming from the burning of fossil fuels, about 10% from nuclear, 7.7% hydroelectric dams, 2.4% from wind, solar, geothermal etc. See the link below for the source.

How should we try to change those numbers in the future? I'm looking for the relative proportions of each source you think we should aim for, e.g. "one third solar, one third wind, one third fossil, a little nuclear" or even exact revised persentages. Or even if you think the current numbers are OK.

http://www.eia.doe.gov/cneaf/electricity/epa/epat2p2.html

WOW that chart was an eye opener! Doing some quick calculations, it revealed the tremendous power output of a typical nuke plant to be 1 gigawatt! That compares to a pitiful 14 megawatts of a so-called "renewable" source.

To answer your question, I would replace ALL of the current fossil fuel plants by nuclear, and leave all the existing hydro, wind and solar stuff in place at least until they can pay for their construction cost. If ever. That would also go a substantial way to divorcing us once and for all from Arab oil.

Solar and wind power are best thought of as niche participants in the strategy since they can be erected where there is no cooling water, such as out in the vast deserts of federally owned lands out west.

Social Acceptance of Wind Power Generation in Scotland $103.56 In the fight against climate change, the Scottish Government has a commitment for half of its total electricity consumption to be produced from renewable sources by 2020. The lions share of the green electricity needed for achieving these very ambitious targets will have to come from wind power. However, recent years show that successfully developing new wind farm sites is far from easy. A certain lack of social acceptance on the local level frequently plays a significant role in this, despite opinion polls indicating an approval rate of over 80 amongst the general public. Explanations for that gap have been sought to help develop recommendations that might facilitate in successfully working with communities to achieve the set climate change targets. Knowledge of wind power generation is sometimes mentioned as a potential factor for peoples attitudes towards wind farms in their own communities. However, research on what actual level of knowledge people possess is rather sparse and relies on the personal selfassessment of the respondents. Therefore, this research focuses on an objective way of furthering the understanding of what people in Scotland know on wind power generation.

Wind Turbines (UK Domestic) $54.86 High Quality Content by WIKIPEDIA articles High Quality Content by WIKIPEDIA articles Wind turbines have been on the United Kingdoms domestic market many years, but their popularity and public awareness is now increasing substantially. Claims about their efficiency and productivity are under some debate due to the disparity of manufacturers forecasts with case study results. The prime problem is that they are routinely being installed in areas with wind speeds much too low to realise a useful level of energy return. Windpowered electricity generation requires wind speeds above those found in the great majority of inhabited areas. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.

Developing Wind Power in South Africa $108.33 The South African electricity industry is easily the largest in Africa, yet it has been unable to meet the countrys energy demands despite its masselectrification programme. Power cuts since late 2007 have become standard practice, while close to a third of the countrys households are not connected to the grid. South Africa also faces environmental problems, particularly in the form of water shortages, and is in the top quartile for most carbon dioxide equivalent gases released by a country. This report evaluates wind power as a sustainable solution to increasing South Africas electricity generating capacity. To identify the countrys wind energy potential, the resource conditions are examined, followed by an analysis of the electricity industry and incentives that aim to promote the adoption of renewable energy. The findings indicate that the country has abundant locations with favourable wind conditions. It is also apparent that new sustainable generation capacity is required and that the recently introduced governmental incentives render certain renewable energy technologies economically feasible.

Renewable Energy in Spain $117.9 High Quality Content by WIKIPEDIA articles Spain has the target of generating 30 of its electricity needs from renewable energy sources by 2010, with half of that amount coming from wind power. In 2006, 20 of the total electricity demand was already produced with renewable energy sources, and in January 2009 the total electricity demand produced with renewable energy sources reached the 34.8. Some autonomous regions in Spain lead Europe in the use of renewable energy technology, and plan to reach 100 renewable energy generation in a few years (objective all electricity from renewable sources, AERS). Castile and Len and Galicia are especially near this goal, producing in 2006 70 of their total electricity demand from renewable energy sources, and 5 communities produce more than 50 from renewables.

Electricity from Poultry Waste in Bangladesh $127.45 Biogas is one of the promising renewable energy sources in Bangladesh. There are about 130 thousand poultry farms in the country and the number of birds in these farms is about 195 million which deliver about 19500 tonnes of chicken droppings a day. Biogas can be produced from poultry droppings through digester technology which in turn can produce electricity through using proper technology. Electricity can be produced from poultry waste for the total daily consumption of most of the poultry farms, and in addition electricity can also be produced for the peak hour only to save farms from being cut off. Electricity generation for 12 hours throughout the day is more financially feasible than producing electricity for 5 hours during peak hour. However, only electricity production is not enough to make the poultry farms financially viable. Fertilizer is the most vital element in addition to electricity to make poultry farms financially feasible. Addition of CO2 cost to income from fertilizer and electricity makes the farms more profitable. Alternatively adding only CO2 cost to electricity cost cannot make the farms feasible in most cases.

Darrieus Wind Turbine $76.47 High Quality Content by WIKIPEDIA articles The Darrieus wind turbine is a type of vertical axis wind turbine used to generate electricity from the energy carried in the wind. The turbine consists of a number of aerofoils usuallybut not always vertically mounted on a rotating shaft or framework. This design of wind turbine was patented by Georges Jean Marie Darrieus, a French aeronautical engineer in 1931. The Darrieus type is theoretically just as efficient as the propeller type if wind speed is constant, but in practice this efficiency is rarely realised due to the physical stresses and limitations imposed by a practical design and wind speed variation. There are also major difficulties in protecting the Darrieus turbine from extreme wind conditions and in making it selfstarting Author: Miller, Frederic P./ Vandome, Agnes F./ McBrewster, John Binding Type: Paperback Number of Pages: 104 Publication Date: 2010/07/01 Language: English Dimensions: 5.98 x 9.01 x 0.24 inches
