Spray-On Solar Cells

May 15, 2017 By EarthWise

One of the most exciting possibilities for future solar energy technology is that of solar cells that can be sprayed or printed on to surfaces like the windows of skyscrapers, the roofs of sports utility vehicles, or the walls of houses. And the expectation is that such technology would be far cheaper than today’s silicon-based solar panels.

Cheap Wind And Solar Power

February 1, 2017 By EarthWise

Multiple studies are now reporting that wind and solar power are the cheapest way to make electricity in a growing number of places around the world. A thorough analysis of the levelized cost of energy – which considers every cost component from capital expenditures to operating and maintenance costs over a lifetime – shows that solar and wind power are winning the day.

There are many good reasons why we should be making the transition from fossil fuel energy sources but the one that is likely to be the most persuasive is strictly economic. It has long been said that the renewable energy future will truly arrive when installing new solar panels is cheaper than a comparable investment in coal, natural gas, or other options.

Wind power is a growing contributor to the energy grid but it has its limitations. Wind turbines need to be located in windy places and the structures are big, get in the way of things, and are rather costly.

Solar Power And Social Justice

July 1, 2016 By WAMC WEB

The U.S. recently celebrated the milestone of having one million solar installations nationwide. It took 40 years to get there, but experts believe the next million could take only a couple of years. The solar revolution is clearly well underway.

We Like Cheap Gas

February 10, 2016 By WAMC WEB

The major auto makers agreed several years ago to a goal of achieving average fuel economy of over 54 miles per gallon by 2025. Motivated by the desire to reduce emissions, getting twice as many miles out of a gallon of gas makes great sense.
