Renewable Energy Won’t Die From Cheap Oil: Bloomberg

Renewable energy won’t die from cheap oil. With oil prices hitting six-year lows, you would think cleantech’s momentum would stop. After all, history has not been kind to renewables when oil prices have fallen. However, Bloomberg Business paints a different picture. In his analysis, author Tom Randall cites 7 key reasons […]
