Wind and solar power will need to expand to account for over 50% of global power generation by 2040 for the world to stand a chance of meeting the Paris Agreement’s target of keeping temperature to 2℃ above pre-industrial levels. But this will require an unprecedented marshalling of investment in carbon-curbing technologies, with current expectations that coal, oil and gas could still be making up the vast majority of primary energy supply as the planet heads for a 2.8℃-3℃ rise by mid-century, according to Wood Mackenzie.
