Many companies are pouring money into renewable energy, but how many can say they're producing more than they need? IKEA thinks it will, at least. Its holding company Ingka revealed that IKEA will generate more renewable energy before the end of 2019 than the energy its stores use. The firm only expected to draw even by 2020. The furniture chain added that it had invested about $2.8 billion in solar and wind energy over the past decade, and told Reuters that it intended to continue funding that renewable tech, including two stakes in American solar farms this week.
