Costa Rica has hit a major milestone: 300 days of renewable energy use, cracking its previous record of 299 days in 2015.

The Costa Rican Electricity Institute (ICE) announced Monday that the country broke its record on Friday and is still going strong.

So far this year, the country’s energy has come from hydro (78.26 percent), wind (10.29 percent), geothermal (volcanoes, 10.23 percent) and solar or biomass (0.84 percent). The remaining 0.38 percent early in the year came from the fossil fuel-powered thermal plants, which now have gone unused for 300 days.

The year 2017 is also poised to be Costa Rica’s biggest year in history for wind production, according to the statement, with 1,014,82 gigawatt-hours thus far coming from 16 wind farms.
