The scale of Chinese production since 2010 has driven the price of these technologies down by 60 to 90 percent, the researchers found. And last year, more than 90 percent of wind and solar projects commissioned worldwide produced power more cheaply than the cheapest available fossil-fuel alternative, they said. That cost advantage might have seemed laughable before China began pumping billions of dollars of subsidies into the sector.
Not only that but the economics of scale are kicking in for solar power and batteries. While oil and gas are more and more expensive, solar power and batteries are getting cheaper
