A recent study by Clean Edge
The clean energy market is booming. According to the report 'Clean Energy Trends in 2008' by Clean Edge, a California clean technologies research and publishing firm, the market for solar energy, wind energy, biofuels, and fuel cells experienced a 40% increase in revenue growth in 2007. Cumulative global wind capacity now exceeds 94,000 MW. Solar capacity is more than 10,000 MW and biofuel production is approximately 15 billion gallons per year. This rapid growth leads to economies of scale and cost reductions, promising even faster growth in the future.
Challenges to overcome
However, Clean Edge also notes a few important challenges that must be overcome in the upcoming years:
