A planned power plant in London will turn globs of discarded fat clogging the city's sewers into the city's newest source of energy. Announced by Thames Water last month, the proposed station will run largely on "fatbergs," giant globs of discarded fat and grease formed from cooking waste that restaurants and residents pour down their drains.

"This project is a win-win: renewable power, hedged from the price fluctuations of the non-renewable mainstream power markets, and helping tackle the ongoing operational problem of 'fatbergs' in sewers," said Piers Clark, commercial director of Thames Water, said in a press release.

The plant is projected to produce 130 Gigawatt hours of electricity a year, or enough to power about 39,000 homes.
