Thailand building floatovoltaic power plant

No, that wasn’t a typo. Float photovoltaic solar panels on a hydropower reservoir and you have a new term—floatovoltaics—but also an elegant hybrid energy system. During the day, you run on solar power. If it’s cloudy and you need more, you spill some water through the turbines. At night you use the hydro power. And if you’re really smart, you use any excess solar power to pump water back into the reservoir.

“Basically, what you do is put the solar modules on rafts on the water and then you feed the power into the grid. That’s all it is. It’s like solar panels on a boat,” says Jenny Chase, a solar analyst at Bloomberg New Energy Finance, a research firm. “Solar’s so cheap now that you want to put it pretty much everywhere you can.”
