Democratic presidential candidate Hillary Rodham Clinton called on Sunday for a dramatic national shift to energy sources such as solar and wind, setting a goal of generating enough clean renewable energy to power every U.S. home within a decade after she takes office.

Clinton, the front-runner for her party's 2016 presidential nomination, also pledged to have more than half a billion solar panels installed nationwide within four years of taking office.

"I want more wind, more solar, more advanced biofuels, more energy efficiency," Clinton said Sunday at a rally in Ames, Iowa. "And I've got to tell you, people who argue against this are just not paying attention."
