Co-ops Add Solar to Portfolios

By Kevin Groenewold | For thousands of years humans have harnessed solar energy to accomplish daily tasks. From starting fires to heating water, the sun powers our society.

At the end of 2009, America’s cumulative solar capacity reached 2,108 megawatts, and in 2010 the top 10 utilities reported they added 561 megawatts of new solar capacity, an increase of 100 percent over 2009.
