Since the turn of the century, the expansion of solar power has surpassed expectations, more than any other energy source.
- 2,919 GW in 2025, according to estimates — solar now supplies about 10% of the world's energy, more than nuclear at 9%.
Data from Taipei-based LowCarbonPower shows that 11% of China's electricity now comes from solar energy.
That's due in large part to the country's strong expansion in renewable energy, especially solar and wind.
The European Union, with 406 GW capacity, ranks second in the world when it comes to solar energy expansion.
Of that, 72% was solar power, followed by wind at 18%, gas at 4%, coal at 3%, hydro at 2% and nuclear at 1%.
Energy experts now believe that solar power will eventually become the world's most important power source. »
