A primary school in Scotland is doing its bit for the environment by being powered almost entirely by wind - and it's all thanks to its pupils.
Cults Primary School in Aberdeen has always been keen on being green but the kids wanted to do more than recycling and remembering to turn the lights off.
As the school is on a big hill, last year some pupils had the idea of using the wind to generate their electricity.
Teachers had to apply for funding, but now they've got their own wind turbine.
Lucy said the wind turbine was a fantastic idea
The turbine generates enough electricity to power all the lights, computers and pretty much everything else they need.
Like every good plan though, the school has got a back up and if there isn't enough wind there's a generator just in case.
Pupils who've been involved in the project said they thought it was great.
"We've been working on it for ages and I'm really proud that we're an eco-school and that we've got a wind turbine," said 10-year-old Lucy.
Robert, 10, added: "I think it looks really good for our school over in the field and since it's a renewable energy source it's much better than things like coal and oil."
