Despite Naysayers, Green Energy Keeps Growing

All together, solar PV, wind and biofuel markets expanded by 31 percent last year to $246 billion globally, according to Clean Edge’s 11th annual edition of Clean Energy Trends 2011, a wrap-up of key green-energy indicators. The expansion caps a five-year run during which these markets have grown by roughly a third each year. Clean Edge expects the markets to grow steadily -- albeit more slowly -- in the decade to come. It projects the clean-energy market will expand by 4.6% per year (compounded) to $385 billion by 2021.
