  • Tesla and SolarCity solar farm on Ta'u, American Samoa

    Electric cars and solar power fit together like a hand in a glove. Charging with solar power, electric cars can drive using almost no non-renewable energy. Now according to a report in Bloomberg New Energy Finance last week, solar investment has dropped by 19 percent worldwide in the second quarter following a trade war between China and the U.S. that includes a 30 percent tariff on Chinese solar panels imported to the U.S. The new tariffs took effect in February. Digging a little further into the data reveals that new investments in renewable energy aren't as dire as a quick glance at those...
