"The solar-power market offers perhaps one of the greatest opportunities among its clean-tech peers. Not only is the worldwide solar market growing by 30% to 50% per year, but the same technologies that enabled the semiconductor and computer revolution are now being leveraged in the solar market."
Ron Pernick and Clint Wilder.The Clean Tech Revolution, 2007, p. 20.
"Perhaps because of its technical, economic, and thermodynamic advantages, a renewable power sector would have six benefits over one reliant on conventional power plants, including (1) lower negative externalities per kWh, (2) more stable and predictable fuel prices, (3) fewer greenhouse gas emissions, (4) less water use, (5) improved efficiency, and (6) greater local employment and revenue."

"Renewable energy provides 18 percent of total net electricity generation worldwide. Renewable energy generators are spread across the globe, and wind power alone already provides a significant share of electricity in some regions: for example, 14 percent in the U.S. state of Iowa, 40 percent in the northern German state of Schleswig-Holstein, and 20 percent in the nation of Denmark. Some countries get most of their power from renewables, including Iceland (100 percent), Brazil (85 percent), Austria (62 percent), New Zealand (65 percent), and Sweden (54 percent)."
