Wind Energy Systems and Alternative Power Sources
Wind Turbines are Extremely Efficient
One of the simplest ways to measure overall efficiency of an energy technology is to look at the “energy payback,” or the amount of energy it takes to produce a given amount of energy. The energy payback time for wind, in fact, is similar to or better than that of conventional power plants.
STEM - The Best Choice for Renewable Energy
STEM is not just a good choice...we are the Best Choice. By forming local partnerships we have been able to circumvent the inevitable lag in product placement and have enjoyed prosperity in building relationships that allow us to outperform competition in the wind energy business.
We understand the essentials of developing and consistently operating a superior wind farm with the ability to continuously feed generation into the local power grid.
Wind power has many advantages
The advantages of wind power are obvious: the energy is free and completely renewable, there are no hazardous emissions, and there are no adverse environmental impacts.
In 1990 in California alone, wind power offset the emission of more than 2.5 billion pounds of carbon dioxide and 15 million pounds of other pollutants – the same amount of air quality provided by more than 150 million trees.
Wind power is also becoming economically competitive with more conventional power sources – a fact that’s greatly improving its prospect as a viable energy source.
Technological innovations have lowered the cost of wind power from more than 30 cents per kilowatt-hour during the 1980s to less than 6 cents per kilowatt-hour today.
High-tech turbines equal low environmental impact. That’s why wind power is gaining public approval and generating increased awareness.
Also, wind farms are modular, so additional turbines can be added if the need arises, and construction time is much shorter than that of a typical fossil fuel power plant.
