Can your foes become your friends? Greenpeace and Italian energy giant Enel just showed us that it’s possible. Just a year after Greenpeace brought the utility company to court for pollution, the two have now joined together to make the Enel the “first truly green energy giant”. Enel, the largest utilities provider in the world by the numbers, has pledged to never build another coal plant again and to be carbon neutral by 2050. The company is also dedicating half of its 27 billion dollar growth investment on expanding solar and wind energy and another third on grid infrastructure in the coming five years. Enel CEO Francesco Starace believes his company represents only the beginning of energy companies ditching fossil fuels for clean energy, saying that most energy companies will make similar moves within the next year.
