Larry Meiller hosts Greg Nemet and Mary Blanchard on WPR to discuss the rising usage of solar power and what the future may hold for this mainstream energy source.

Would it be possible to harness energy in space for use on Earth? Dan Ludois, professor of electrical and computer engineering, responds to this question on a Blue Sky Science spotlight.

Researchers from the UW–Madison found that consumers who are diligent about turning off lights when they leave rooms are not only saving energy and money, but they could also be saving lives, as the action helps to cut down on air pollution.

When Greg Nemet began studying solar energy in 2002, it was not considered a viable alternative to traditional fossil fuels. Today, large-scale solar farms are more cost-efficient than virtually all other sources, even in places like Wisconsin, where regulators recently approved projects that will result in a five-fold expansion of solar capacity. So what caused the prices to plummet?

Madison Gas & Electric's new goal of net-zero carbon electricity by 2050 is feasible, according to Tracey Holloway and Greg Nemet, two UW–Madison environmental studies researchers.
