"Carbon-free electricity has never been more plentiful. Wind and solar power have taken off over the past two decades, faster than experts ever expected. But it hasn’t yet been enough to halt the rise of coal- and gas-burning generation.
That’s because global demand for electricity has grown even faster than clean energy, leaving fossil fuels to fill the gap.
The dynamic has pushed up carbon emissions from the power sector at a time when scientists say they need to be falling — and fast — to avoid dangerous levels of global warming.
Much of the rising power demand has come from rapidly-developing countries like China and India, where new coal plants are still coming online alongside wind and solar farms to power meteoric economic growth. But many industrialized nations are also not moving away from fossil fuels fast enough to meet their stated climate change goals."
