Teachers, save “Maths in sustainability- Solar power” to assign it to your class.

We use electrical energy to power our homes, schools and places of work. Generating electricity by burning coal or gas in a power station is not sustainable, and produces carbon dioxide. Using sunlight to make electricity is sustainable. A solar panel is a grid of photovoltaic cells that convert sunlight into electric power. Power is measured in watts. One kilowatt (kW) = 1000 watts (W).
