More and faster: Electricity from clean sources reaches 30% of global total

Billions of people are using different kinds of energy each day and 2023 was a record-breaking year for renewable energy sources — ones that don’t emit planet-warming pollutants like carbon dioxide and methane — according to a report published Wednesday by Ember, a think tank based in London.

For the first time, 30% of electricity produced worldwide was from clean energy sources as the number of solar and wind farms continued to grow fast.

Of the types of clean energy generated last year, hydroelectric dams produced the most. That’s the same as in most years. Yet droughts in India, China, North America and Mexico meant hydropower hit a five-year low. Research shows climate change is causing droughts to develop more quickly and be more severe.

People used more electricity than ever last year, about 2% more, an increase of about as much as Canada uses in a year. Some of this new demand was for heat pumps, which are an efficient way to both heat and cool buildings, and for electric vehicles. It was also for electrolyzers, special machines used to get hydrogen out of water, for energy. These are all technologies that provide solutions to climate change.

Other increased demand was for electricity to feed new data centers and for air conditioning as places around the world become hotter.

Solar made up the biggest share of new clean energy last year. More than twice as much solar power was added as coal power. It was the 19th year in a row that solar was the fastest-growing source of electricity generation. A surge in solar installations happened at the end of the year and the report predicts 2024 will see an even larger jump.
