Hot stones could help hold the key to a clean energy future

Renewable energy is now cheaper than fossil fuels, and it’s less expensive to build and run a solar or wind farm than to operate a coal plant that already exists. That’s a huge win for cutting carbon emissions in energy production, and it’s broadened opportunities for innovation in power generation for the future. On today’s episode of the World Changing Ideas podcast, we explore some of those renewable options, as well as how cost will continue to be a factor in the popularity of their use.We first speak to a company called Clearloop, which uses carbon offsets donated by private companies to fund local solar projects, particularly in areas that still rely on carbon-intense energy sources. “Any company that wants to offset a portion of their carbon footprint can help us subsidize a number of watts that then help us essentially crowdfund the construction of a solar…
