We've seen a number of entities announce plans to operate with 100% renewable energy over the years. Costa Rica, for example, has gone 76 straight days using 100% renewable electricity. General Motors is the latest company to release a roadmap to achieving 100% renewable energy. The catch? It won't be until 2050. CleanTechnica reports: American multinational General Motors, or GM, has committed to generating or sourcing 100% of the electricity for its operations across 59 countries from 100% renewable energy by 2050. GM made the announcement on Wednesday, revealing that it planned to generate or source all its electrical power needs for its 350 operations in 59 countries with 100% renewable energy such as wind, solar, and landfill gas, by 2050. In turn, the company has joined the 100% renewable energy campaign RE100, lending its considerable global business weight to an already important and successful campaign. "Establishing a 100% renewable energy goal helps us better serve society by reducing environmental impact," said Mary Barra, GM Chairman and CEO. "This pursuit of renewable energy benefits our customers and communities through cleaner air while strengthening our business through lower and more stable energy costs."
