From the windy plains to the sunny southwest, energy companies around the U.S. are investing heavily in renewable energy production. More than half of the energy production equipment being planned for installation in the next few years is renewable. Yet despite the environmental and economic sense of renewable energy, the public conception still lingers that wind and solar and other renewable tech will never be able to quite handle the job. After all, do we expect factories and homes to go dark when the sun sets or the wind falters?

In the video above, physicist and environmentalist Amory Lovins explains how renewable energy should be able to keep the electricity flowing just fine. We won't need any big technological breakthroughs in batteries or storage technology, he says, or any other huge breakthroughs. All we'll really need is good management and a diverse array of renewable energy production equipment.

Amory Lovins is the co-founder of the Rocky Mountain Institute, a think tank working on energy and resource use issues. This video was based on a presentation Lovins gave at the 2014 TED conference.
