'Sustainable' Energy In a Depression

If the Dow fell 85 percent, most folks would call that a depression. So why doesnâ??t that apply to the â??sustainableâ? energy business - mainly solar and wind power - where shares have fallen an average of 85 percent to 90 percent, even excluding the bankrupt Solyndras, Evergreens and Solons? This depression is global, hitting Chinese Suntech, the worldâ??s largest producer of solar panels, as well. Suntech has seen its shares plunge 88 percent.
