This startup helps build solar panels where they’re most needed

Most of the new solar panels that are being built in the US are located in states where the process is easiest or policies are most favorable, instead of where solar could have the biggest impact on reducing CO2 emissions. A Nashville-based startup, called Clearloop, wants to change that by Read More...

Four strategies to make solar

Four strategies to make solar panels even more sustainable

Solar energy is a renewable source with fairly high reliability and scalability, but even the best solutions have some drawbacks. In the case of solar, the panels themselves are emissions-intensive to produce and require mined silicon, glass, and aluminum. As we continue to improve the Read More...

German farm demonstrates dual benefits of agrivoltaic systems

Agrivoltaic systems make for the perfect symbiotic relationships on farms. They combine solar panels and farming to provide localized renewable energy while helping shade crops to reduce water usage. The plants also work to cool the solar panels for increased productivity. At one farm in Germany, Read More...

First Solar to build huge solar factory in Ohio

Making our way to a renewable energy future means establishing the infrastructure needed to provide solar panels, wind turbines, and more to the entire US. Today, most solar energy panels and equipment are made in China, but the ease of access for US consumers may soon increase as First Solar has Read More...

Solar panels and California

Solar panels and California's water canals: A match made in heaven

About 4,000 miles of canals transport water to some 35 million people and 5.7 million acres of farmland across California. As the state enters another year of severe drought, researchers from the University of California have come up with a proposition to cover these canals with solar panels to Read More...
