When it comes to energy consumption, schools are one of the biggest users.
Now, a new initiative is aimed at helping schools to address this, with the help of the children.
30 schools across the county have signed up to the county council scheme to help improve energy efficiency, with each school appointing carbon ambassadors to make it happen.
And among the SCoRE programme - Schools Collaboration on Resource Efficiency - is Legsby School, where Edward Parrish, Sinead McCann and Alicia Barnes have taken up the challenge.
“They have all been very enthusiastic to do their bit to save energy, and they are not shy at telling us where we can do better,” said headteacher David Miskell.
“The whole point is to make children aware of energy efficiency and recycling.
“They can all be very pleased with their efforts, which have been good for the staff as well as the children.”
Before their training day with ambassadors from other schools, the Legsby trio had to complete an energy audit and since doing that have their own ideas of ways they would like to improve things at their school.
“I would like to see solar panels and plastic strip curtains to help with energy efficiency, but we need to raise the money,” said Edward (10).
Meanwhile, the group, with the help of electricity monitors, continue to check things are switched off each day, issuing happy or sad faces along the way.
“Some teachers do forget to turn the lights off, ” added Edward.
