Spain is getting the vast majority of its electricity from carbon-free sources, the country’s grid operator reported on Tuesday.

According to Red Electrica de Espana (REE), the Spanish peninsula got 69 percent of its electricity generation in March from technologies that produce zero carbon emissions — that is to say, renewable energy plus some of its nuclear power. Nuclear as a whole provided 23.8 percent of the country’s electricity in March, while 47 percent came solely from renewable sources.

Most of the renewable electricity being generated in Spain comes from wind, which alone provided 22.5 percent of the country’s electricity last month. Wind often competes with nuclear for the title of Spain’s top electricity generation source overall — in fact, though nuclear pulled through in March as the top source of electricity, wind has overall provided more electricity to Spain in the entirety of 2015. From January to March, according to REE, wind provided 23.7 percent of electricity generation while nuclear made up 22.7 percent.
