According to Reuters, the Democratic presidential candidate pledged to have at least half a billion solar panels installed nationwide within four years of her taking office.

"I want more wind, more solar, more advanced biofuels, more energy efficiency," Clinton said. Replying Republican candidates who do not believe climate change is a serious enough threat for immediate government action, Clinton said, "And I’ve got to tell you, people who argue against this are just not paying attention. The reality of climate change is unforgiving no matter what the deniers say."

These goals would be the first of Clinton’s comprehensive climate-change agenda, which will be released in the coming months.

Clinton has been facing challenges from Democratic presidential rival Senator Bernie Sanders, who has been campaigning for swift action on climate change. Clinton sees climate change as a winning issue which can can tip the scales against Republicans in for the forthcoming 2016 elections.

Clinton’s goals should lead to a 700 percent increase in the nation's installed solar capacity from current levels, which eventually could lead to the generation of at least a third of all electricity from renewable sources.

Clinton also called for extending more federal tax incentives to make renewable energy more cost effective. Clinton plans to continue the wind production tax credit and to promote fossil fuels.

Clinton also pledged to continue President Barack Obama's actions to limit carbon emissions from power plants, and take further action to build a growing "clean energy economy". If we start addressing it, we're going to actually be creating jobs and new businesses," Clinton said.

Clinton will discuss her proposals at an energy-efficient transit station in Iowa, a leading wind energy producer, where Clinton chose to start her 2016 presidential nominating race. Praising Iowa for its policies to promote wind energy and advanced biofuels, Clinton said that the state’s tax rebates for installing solar panels in homes and businesses should be a role model to other states.
