The world's largest concentrated solar power plant has been opened in Abu Dhabi in the United Arab Emirates.
Shams 1 - which means sun in Arabic - cost a whopping £400 million to build and will provide electricity to 20,000 homes.
Its special mirrors spread over an area the size of 285 football pitches.
It's thought it will save 175,000 tonnes of carbon dioxide every year, equivalent to taking 15,000 cars off the road.
And as it's in the desert, automatic trucks have to dust sand off the mirrors to keep it working efficiently.
