"Europe: No. 1 in Sustainable Energy"

"Currently more than 25,000 wind farms are operating throughout Europe,
and capacity is expected to double by 2015.
....
Similarly, solar panel capacity in Germany, the world's largest market
with annual sales over $5 billion, is expected to reach 4,500 megawatts by
2010-the equivalent of almost six coal-fired power stations.
....
Ocean Power Delivery, a Scottish company that has designed a turbine
powered by wave energy, has targeted North America as a key battleground.
Growth in the U.S., according to the company's Business Development
Director Max Carcas, could propel the wave-power sector to a $10
billion-per-year industry by 2012."
