As the summer continues, much of the energy during the day is generated by solar power. According to ERCOT data, Monday around 15 percent of the supply came from the sun. At night, a good chunk of it comes from wind power.
Earlier in the summer the Public Utility Commission announced at a May press conference the state could not keep up with the growing population without wind and solar power.So despite 12 hourly demand records being broken since June 26, the power grid has had enough supply. "I don't want to pay too much so I keep it around that. I prefer it to be a bit more chilly but I keep it at that so the bill doesn't go too high up," Lopez said.
