Spain has reached a historic milestone by powering its mainland electricity grid entirely with renewable energy. On April 16, 2025, wind, solar, hydropower, and other renewable sources together supplied 100% of Spain’s mainland electricity demand. Wind energy led the mix, generating nearly 46% of total power, followed by solar at around 27% and hydropower at approximately 23%. At 11:15 a.m., electricity production from wind and solar alone exceeded national demand, a rare achievement for a large

France experienced a rare electricity market event where power prices temporarily dropped to zero. This happens when supply exceeds demand so strongly that generators are willing to sell electricity at no cost. The main drivers are high nuclear output combined with strong renewable generation from wind and solar. When consumption is low and production remains high, the grid becomes oversupplied. Electricity is difficult to store at large scale, so excess power must be used immediately. Instead o

In parallel with using the water surface for electricity generation, these plants also reduce water evaporation by blocking sunlight, helping to preserve fresh drinking water. | Electronique & Electricité | Facebook
