This report shows evidence that wind and solar have quickly increased to become a major source of electricity in most countries in the world, and are successfully reducing coal generation throughout the world. Ember’s new half-year analysis aggregates national electricity generation for 48 countries making up 83% of global electricity production. It builds on Ember’s annual Global Electricity Review, released in March 2020. Wind and solar generation rose 14% in the first half of this year (H1- 2020) compared to H1-2019, generating almost a tenth (9.8%) of global electricity. In the 48 countries analysed, wind and solar generation rose from 992 terawatt hours in 2019 to 1,129 terawatt hours in H1-2020. That meant wind and solar’s share of global electricity has risen from 8.1% in 2019 to 9.8% in H1-2020.
