Seven countries now generate 100% of their electricity from renewable energy

Seven countries now generate almost all of their electricity from renewable energy sources, according to recently compiled figures.

Albania, Bhutan, Nepal, Paraguay, Iceland, Ethiopia and the Democratic Republic of the Congo produced more than 99.7% of the electricity they consumed using geothermal, hydro, solar or wind energy.

Data from the International Energy Agency (IEA) and the International Renewable Energy Agency (IRENA) also revealed that another 40 countries generated at least 50% of the electricity they consumed from renewable energy technologies in 2021 and 2022. , including 11 European countries.

“We don’t need miracle technologies,” says Mark Jacobson, a Stanford University professor who published the data.

“We have to end emissions by electrifying everything and supplying electricity with wind, hydro and solar (WWS), which includes onshore wind, solar photovoltaics, concentrated solar power, geothermal electricity, small hydro and large hydroelectricity.”

Professor Jacobson also noted that other countries, such as Germany, were also able to run on 100% electricity generated from renewable sources for short periods of time.

Figures published by the IEA in January show that the UK generated 41.5% of its electricity from renewable sources in 2022, up 10.5% on the previous year.

In Scotland, renewable energy technologies generated the equivalent of 113% of the country’s total electricity consumption in 2022.

“These record figures are an important milestone on Scotland’s path to net zero energy, and clearly demonstrate the enormous potential of our world-class renewable energy resources,” Claire Mack, chief executive of Scottish Renewables, said at the time.

While electricity generation in Scotland was dominated by wind power, researchers predict that solar power will come to dominate the global electricity supply in the coming decades.

In recent years, much progress has been made in improving the efficiency of solar cells, especially thanks to the so-called “miracle material” called perovskite.

Commercial costs have also fallen, leading scientists at the University of Exeter and University College London to say last year that solar energy has reached an “irreversible tipping point” that will make it the leading energy source. of the world in 2050.

His work, written in 2023 and published in the magazine Nature Communicationsconcludes that technological and economic advances make the transition to clean energy not only achievable, but inevitable.

“Due to the technological trajectories set in motion by past policies, an irreversible solar tipping point may have been passed in which solar energy gradually comes to dominate global electricity markets, without the need for new climate policies.” , the researchers write in the study.

“Solar energy is the most widely available energy resource on Earth, and its economic attractiveness is improving rapidly in a cycle of increasing investments.”
