Global renewable energy investment growth (1995-2007)[1]

The renewable-energy industry is the part of the energy industry focusing on new and appropriate renewable energy technologies. Investors worldwide have paid greater attention to this emerging 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.

In 2020, the global renewable energy market was valued at $881.7 billion [2] and consumption grew 2.9 EJ.[3] China was the largest contributor to renewable growth, accounting an increment of 1.0 EJ in consumption, followed by the US, Japan, the United Kingdom, India, and Germany. In Europe, renewable consumption incremented 0.7 EJ.[3]

Renewable energy power growth in GW (2004-2011)


Net-zero global goals create market opportunities for renewable industries such as solar and wind energy and lithium-ion batteries. By 2050, it’s estimated that the renewable market will reach a value of one trillion dollars, the same size as the current oil market.[4]

In 2020, renewable sources incorporated into energy consumption at its fastest rate in two decades.[4]

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.[1]

Renewable energy industries expanded during most of 2008, with large increases in manufacturing capacity, diversification of manufacturing locations, and shifts in leadership.[5] By August 2008, there were at least 160 publicly traded renewable energy companies with a market capitalization greater than $100 million. The number of companies in this category has expanded from around 60 in 2005.[6] : 15 

Some $150 billion was invested in renewable energy globally in 2009, including new capacity (asset finance and projects) and biofuels refineries. This is more than double the 2006 investment figure of $63 billion. Almost all of the increase was due to greater investment in wind power, solar PV, and biofuels.[7]: 27 

In 2000, venture capital (VC) investment in renewable energy was about 1% of total VC investment. In 2007 that figure was closer to 10%, with solar power alone making up about 3% of the entire Venture Capital asset class of ~$33B. More than 60 start-ups have been funded by VCs in the last three years.[8] Venture capital and private equity investments in renewable energy companies increased by 167 percent in 2006, according to investment analysts at New Energy Finance Limited.[9]

New investment into the sector jumped US$148 billion in 2007, up 60 per cent over 2006, noted a report by the Sustainable Energy Finance Initiative (SEFI). Wind energy attracted one-third of the new capital and solar one-fifth. But interest in solar is growing rapidly on the back of major technological advances which saw solar investment increase 254 per cent.[10] The IEA predicts US$20 trillion will be invested into alternative energy projects over the next 22 years.[10]

Wind power[edit]

In December 2008, worldwide capacity of wind power was 122,000 MW, of which 28,190 MW was capacity added in 2008.[12]


Vestas was the largest wind turbine manufacturer in the world with and 16% market share in 2020.[13] The company operates plants in Denmark, Germany, India, Italy, Britain, Spain, Sweden, Norway, Australia and China,[14] and employs more than 20,000 people globally.[15] After a sales slump in 2005, Vestas recovered and was voted Top Green Company of 2006.[16][17]

In 2020, Siemens Gamesa was the world's second largest wind turbine manufacturer in 2020 thank to its position in the offshore sector of India. The company lead the offshore wind market.[18]

Other major wind power companies include GE Power, Suzlon, Sinovel and Goldwind.[13][19]


Although the wind power industry will be impacted by the global financial crisis in 2009 and 2010, a BTM Consult five year forecast up to 2013 projects substantial growth. Over the past five years the average growth in new installations has been 27.6 per cent each year. In the forecast to 2013 the expected average annual growth rate is 15.7 per cent.[5][12] More than 200 GW of new wind power capacity could come on line before the end of 2013. Wind power market penetration is expected to reach 3.35 per cent by 2013 and 8 per cent by 2018.[5][12]

Offshore wind power installations are emerging, and recent years have seen several hundred megawatts added annually, mostly in Europe.[1]: 10 



Monocrystalline solar cell

First Solar became the world's largest solar cell maker in 2009, producing some 1,100 MW of product, with a 13% market share. Suntech was in second place with a production of 595 MW in 2009 and market share of 7%.[20] Sharp Solar was far behind the leader with 580 MW of output. Q-Cells and its 540 MW output was fourth in 2009. Yingli Green Energy, JA Solar Holdings, SunPower, Kyocera, Motech Solar and Gintech rounded out the 2009 Top 10 ranking.[20]


Solar production has been increasing by an average of some 20 percent each year since 2002, making it the world’s fastest-growing energy technology.[21][22] At the end of 2009, the cumulative global PV installations surpassed 21,000 megawatts.[22][6]: 12 

According to the China Greentech Report 2009, jointly issued by the PricewaterhouseCoopers and American Chamber of Commerce in Shanghai and released on 10 Sept in Dalian, China, the estimated size of China's green technology market could be between US$500 billion and US$1 trillion annually, or as much as 15 percent of China's forecasted GDP, in 2013. With the positive drivers from the Chinese government’s policies to develop green technology solution, China has already played a more important role in green technology market development.[23] Following the announcements of the Chinese government in 2009 about the new subsidy scheme of “Golden Sun” to support solar industry development in China, some of the worldwide industry players have announced their development plans in this region, such as the agreement signed by LDK Solar regarding a solar project in Jiangsu province with a total capacity of 500MW,[24] manufacturing facilities of polysilicon ingots and wafers, PV cells and PV modules to be built by Yingli Green Energy in Hainan Province,[25] and the new thin film manufacturing plants of Tianwei Baoding[26] and Anwell Technologies.[27]

Concentrating solar power[edit]

The 11MW PS10 solar power tower near Seville in Spain.

Since 2004 there has been renewed interest in concentrating solar power (CSP) and three plants were completed during 2006/2007: the 64 MW Nevada Solar One, a 1 MW trough plant in Arizona, and the 11 MW PS10 solar power tower in Spain. Three 50 MW trough plants were under construction in Spain at the end of 2007 with ten additional 50 MW plants planned. In the United States, utilities in California and Florida have announced plans (or contracted for) at least eight new projects totaling more than 2,000 MW. Companies involved in new projects include Abengoa Solar, Acciona, Ausra, BrightSource Energy, Iberdrola, Solar Euromed, Solar Millennium and Stirling Energy Systems.[1]: 12 and 19 [28]


Brazil continued its ethanol expansion plans which began in the 70's and now has the largest ethanol distribution and the largest fleet of cars run by any mix of ethanol and gasoline.[1]: 19

In the ethanol fuel industry, the United States dominated, with 130 operating ethanol plants in 2007, and production capacity of 26 billion liters/year (6.87 billion gallons/year), a 60 percent increase over 2005. Another 84 plants were under construction or undergoing expansion, and this will result in a doubled production capacity. The biodiesel industry opened many new production facilities during 2006/2007 and continued expansion plans in several countries. New biodiesel capacity appeared throughout Europe, including in Belgium, Czech Republic, France, Germany, Italy, Poland, Portugal, Spain, Sweden, and the United Kingdom.[1]: 19 

Commercial investment in second-generation biofuels began in 2006/2007, and much of this investment went beyond pilot-scale plants. The world’s first commercial wood-to-ethanol plant began operation in Japan in 2007, with a capacity of 1.4 million liters/year. The first wood-to-ethanol plant in the United States is planned for 2008 with an initial output of 75 million liters/year.[1]: 19 


Renewable energy use tends to be more labor-intensive than fossil fuels, and so a transition toward renewables promises employment gains. In 2019, 11.5 million people work either directly in renewables or indirectly in supplier industries.[29] The wind power industry employs some 1.7 million people, the photovoltaic sector accounts for an estimated 3.7 million jobs, and the solar thermal industry accounts for about 820,000. More than 3.58 million jobs are located in the biomass and biofuels sector.[29]
