Investors worldwide have paid much greater attention to this emerging renewable energy industry in recent years. In many cases, this has translated into rapid renewable energy commercialization and considerable industry expansion. The wind power and solar photovoltaics (PV) industries provide good examples of this.Leading renewable energy companies include Acciona, Enercon, Gamesa, GE Energy, Q-Cells, Sharp Solar, SunOpta, Suntech, and Vestas.[2] Several renewable energy companies have recently gone through high profile Initial Public Offerings, including Aventine (USA), First Solar (USA), Iberdrola (Spain), and VeraSun Energy (USA).[3]Contents1 Overview 2 Wind power 2.1 Companies 2.2 Trends 3 Photovoltaics 3.1 Companies 3.2 Trends 4 Concentrating solar power 5 Biofuels 6 Employment 7 See also 8 References 9 Bibliography 10 External links // OverviewBy mid-2007, some 140 publicly-traded renewable energy companies worldwide (or renewable energy divisions of major companies) each had a market capitalization greater than $40 million. (The number of companies in this category jumped from about 85 in mid-2006.) The estimated total market capitalization of these companies and divisions was more than $100 billion in mid-2007.[3]During 2006/2007, several renewable energy companies went through high profile Initial Public Offerings (IPOs), resulting in market capitalization near or above $1 billion. These corporations included the solar PV companies First Solar (USA), Trina Solar (USA), Centrosolar (Germany), and Renesola (U.K.), wind power company Iberdrola (Spain), and U.S. biofuels producers VeraSun Energy, Aventine, and Pacific Ethanol.[3]Continued growth for the renewable energy sector is expected in the mid- to long-term, but 2009 will be a year of refocus, consolidation, or retrenchment for many companies. At the same time, new government spending, regulation, and policies should help the industry weather the current economic crisis better than many other sectors. Clean Edge suggests that the commercialization of clean energy will help countries around the world pull out of the current economic malaise.[4]Wind powerSee also: Wind power industryIn 2007, worldwide capacity of wind-power was 93.8 GW, of which 19.7 GW was capacity added in 2007.[5]CompaniesVestas V80 wind turbinesSee also: List of wind turbine manufacturersCurrently three quarters of global wind turbine sales come from only four turbine manufacturing companies: Vestas, Gamesa, Enercon, and GE Energy.[6] With a 23% market share, Vestas is the largest supplier of modern wind turbines. Vestas has installed some 35,000 wind turbines in 63 countries on five continents. Vestas wind turbines generate more than 60 million MWh of energy per year: enough electricity to supply millions of households. Vestas is a Danish company which employs 14,000 people globally.[7]Gamesa, founded in 1976 with headquarters in Bilbao, Spain, is currently the world's second largest wind turbine manufacturer,[2][8] after Vestas, and it is also a major builder of wind farms. Gamesa main markets are within Europe, the US and China. In 2006, Europe accounted for 65 percent of Gamesa sales, of which 40 percent were within Spain.[6]In 2004, German company Enercon installed a total of 1,288 MW of wind power and had around 16% of the global market share. Enercon constructed production facilities in Brazil in 2006, and has extended its presence there, as well as in the more traditional markets of Germany, India, Austria, UK, Canada and the Netherlands.[2]GE Energy has installed over 5,500 wind turbines and 3,600 hydro turbines, and its installed capacity of renewable energy worldwide exceeds 160,000 MW.[9] GE Energy bought out Enron Wind in 2002 and also has nuclear energy operations in its portfolio.[10]Acciona Energy is a leader in the renewable energy sector and the company mission is to "demonstrate the technical and economic viability of a sustainable energy model".[11] Acciona Energy is the largest developer, owner and operator of wind farms in the world, with 164 wind farms in nine countries representing over 4,500 MW of wind power installed or under construction.[11]TrendsWind power capacity increased more than any other renewable power technology in 2007, with an estimated 21 GW added, which represented a 28 percent increase over 2006.[12] In 2007, the wind power industry saw an increase in wind manufacturing facilities in the United States, India, and China, which broadened...(and so on)
