Wind Boom
Wind energy generation is booming [pdf]. Brussels, 2 February 2007. The booming wind energy markets around the world exceeded expectations in 2006, with the sector experiencing yet another record year. On the day of the publication of the 4th Assessment Report on Climate Change by the IPCC, the Global Wind Energy Council (GWEC) released its annual figures for 2006. These figures, which include wind energy developments in more than 70 countries around the world, show that the year saw the installation of 15,197 megawatts (MW), taking the total installed wind energy capacity to 74,223 MW, up from 59,091 MW in 2005.China is getting into the act. One of the resons for this is that China uses coal for most of its electrical generation. One of the major sources of air pollution in China. Asia has experienced the strongest increase in installed capacity outside of Europe, with an addition of 3,679 MW, taking the continent over 10,600 MW. In 2006, the continent grew by 53% and accounted for 24% of new installations. The strongest market here remains India with over 1,840 MW of new installed capacity, which takes its total figure up to 6,270 MW.How is North America doing? 22% of the world's new wind capacity was installed in North America, where the annual market increased by a third in 2005, gaining momentum in both the US and Canada.2,500 MW of new capacity is roughly equivalent to one nuke plant. How many nuke plants were added last year? Zero. How many are expected next year? Zero. How many are projected to be built in the next five years? Zero. A 25% a year increase in the rate of capacity installation means that within three years or so we will be installing two nuke plants worth of wind a year. In six years that will be four nukes worth of wind per year. etc. An astounding rate of increase for such large systems. You don't need a weather man to know which way the wind blows.
