Happy Earth Day, one day late:
Duke Energy aims to more than double the wind, solar and biomass energy in its portfolio by 2020, according to its 2012 sustainability report.
Duke Energy Renewables, a nonregulated unit, now owns most of the company’s renewable generation – about 1,700 megawatts.
Most of the generation is from wind projects in six states, but the unit has seven solar farms in North Carolina and others in Texas, Arizona and Florida.
The business is growing fast, in part because of federal tax credits.
Looking at the picture I drew in class yesterday, the tax breaks push the backstop fuel price down and hurries up the switch point:
Don't you wish you could be in my class every single gosh dang day!
