Solar generation increased by 23% last year and wind by 14%. Combined, this brings them to over 10% of global electricity generation. The data comes from the Global Electricity Review report, prepared by Ember, an independent energy institution.
Also according to the research, all clean sources of electricity generated 38% of the world's electricity in 2021, more than coal (36%).
According to Ember, to be on a path that keeps global warming to 1.5 degrees, wind and solar energy need to sustain high compound growth rates of 20% each year until 2030. This is the same growth rate as the average in last decade.
“This is now eminently possible: wind and solar are the lowest-cost sources of electricity on a level basis, with increasing global experience of integrating them into high-level grids. With 50 individual countries now generating more than 10% of their electricity from these rapidly deployable resources, and three countries already generating more than 40%, it is already clear that these technologies are delivering,” highlighted Dave Jones, global leader at Ember.
The report further points out that governments such as the US, Germany, UK and Canada are so confident in clean electricity that they plan to switch their grid to clean 100% electricity in the next decade and a half. But with coal still rising and demand for electricity continuing to rise, all governments with carbon-intensive networks need to act with the same boldness and ambition.
“Wind and solar have arrived. The process that will reshape the existing energy system has already begun. This decade, they need to be deployed at lightning speed to reverse the rise in global emissions and combat climate change,” concluded Daves.
