On Sunday afternoon Germany got clean, as renewables supplied 45.5 gigawatts of the country’s 45.8-gigawatt energy demand. In fact, power prices even went negative for a bit. This is a huge milestone for Chancellor Angela Merkel, who has sought to push her nation away from nuclear and fossil fuels.

Clean energy is becoming more viable. Denmark supplied 140 percent of demand by wind farms last year.

But as Bloomberg energy finance analyst Monne Depraetere explained, Europe still has a lot of work to do because the continent is getting better at renewables, saying, “Events like this highlight that eventually we may need to start curtailing because of market-wide oversupply. In the long-run, that may provide a case to build technologies that can manage this oversupply — for example more interconnectors or energy storage.”

These are good energy problems to have.
