The Ongoing March of Clean Energy

Last year half of all investment in energy production worldwide was in renewable energy; this represents a 17% increase in such investment, to $270 billion. That's 103 Gigawatts of capacity in a single year. To put it another way, more solar and wind power capacity was ordered in 2014 than existed in the world in 2000. And this isn't being driven by nervous Greens in Europe. Four of the countries making big investments were China, India, Brazil, and South Africa; across the developing world investment in clean energy rose 36%.
