Looking for an investment opportunity in green tech? Wind power technologies have been seeing a little more action in the green technologies market recently. Just a couple a weeks ago, I have seen a lot of investment activity into wind power, both in the United States and abroad.
Massachusetts-based First Wind Holdings has announced that it is going public, and hopes to raise up to $450 million in its initial public offering. They currently have 92 megawatts of operating capacity, with plans to increase that capacity to 1,100 megawatts by the end of 2010 and 2,300 megawatts by the end of 2013.
Oregon-based Iberdrola Renewables has signed a deal with Arizona utility Salt River Project, who will be purchasing power from Iberdrola’s planned 63 megawatt Dry Lake Project wind farm. The Dry Lake Wind Project will be the first wind farm built in Arizona.
Across the Atlantic, Italy’s largest electric utility, Enel has signed an agreement to take a 30 percent stake in a 1,400 megawatt pipeline of wind projects in Greece.
Currently, the U.S. generates only about 1% of its electricity from wind power, but the Department of Energy hopes to increase that number to 20% by the end of 2020, which means opportunity for those in the position to get involved in the wind power market.
So what does this have to do with ultracapacitors? Wind power generation and the ultracapacitor are complementary technologies, since we need to be able to store some of that power. Also ultracapacitors are used in windmills to control the pitch and movement of the blades. Can we expect to see more widespread use of the ultracapacitor, as sustainable energy sources are further developed and become more available? No Doubt! Ultracapacitors are making their mark now in many applications.

20% by 2012? That would be great if it were true, but I'm afraid the actual date should read 2020.
It all comes down to what's cheapest in a given location. Alternatives include pumped storage, compressed air, flow batteries and flywheels.
So far I haven't seen any projects considering capacitors as an option, but if the price gets low enough I'm sure it will happen. But that's a big "if".
