People are being asked to switch off their lights as part of their Big Power Switch Off in the UK.
Homes across the country plunged into darkness to protest against energy prices on Sunday, April 10.
One person who took part in the event said on Twitter: "Sitting in the darkness for the big power switch off was somewhat peaceful but bittersweet. A massive [middle finger] to energy companies and the government though. #BigPowerOff"
