by Rebecca Walker — March 16, 2011—Clean Edge, a research and advisory company, has published its 10th annual Clean Energy Trends report, an in-depth look at the state of the markets for solar power, wind energy and biofuels.
The report also looks at investments in cleantech companies, valuations of IPOs in clean energy and performance of stock indices for the cleantech sector.
The findings show steady growth over the past decade for all three sectors, with wind and solar averaging 30 and 40 percent growth, respectively, since the first report in 2000. The combined global revenue for solar, wind and biofuels grew 35.2 percent in 2010, up to $188.1 billion from $139.1 billion in 2009.
The decade has also shown that original projections, published in Clean Tech: Profits and Potential in April 2001, ended up being conservative. The authors write: “We projected that solar power would grow from a global market of $2.5 billion in 2000 to $23.5 billion by 2010 and that wind power would grow from a global market of $4 billion in 2000 to $43.5 billion by 2010. But […] we were actually quite conservative in our estimates, coming up around 300 percent short in our solar PV estimates and approximately 50 percent short in our wind estimates.”
