| Wind power drives global renewable energy growth The REN21 Global Status Report shows that renewable energy continues its strong performance despite continuing economic turmoil, cuts in incentives and subsidies and low natural gas prices. The growth of wind power in particular continues to drive renewable energy development, but other sectors such as solar PV are also seeing strong investment. According to the report, trends for wind power include continued offshore development, the growing popularity of community-based projects and distributed, small-scale grid-connected turbines, and the development of wind projects in a wider variety of geographical locations. Average turbine sizes continued to increase in 2010, with some manufacturers launching 5 MW and larger turbines, and direct-drive turbine designs captured 18% of the global market In 2010, renewable energy supplied an estimated 16% of global final energy consumption and delivered close to 20% of global electricity production. Renewable capacity now comprises about a quarter of total global power-generating capacity. Including all hydropower (estimated 30 GW added in 2010), renewable energy accounted for approximately 50% of total added power generating capacity in 2010. Renewable energy policies continue to be the main driver behind renewable energy growth. By early 2011, at least 119 countries had some type of policy target or renewable support policy at the national level, more than doubling from 55 countries in early 2005. More than half of these countries are in the developing world. At least 95 countries now have some type of policy to support renewable power generation. Of all the policies employed by governments, feed-in tariffs remain the most common. Last year, investment reached a record $211 billion in renewables - about one-third more than the $160 billion invested in 2009, and more than five times the amount invested in 2004. write your comments about the article :: © 2011 Exhibition News :: home page |
