The over usage of electricity!
What does it mean?
It means we are over using electricity! Our electricity comes from burning fossil fuels which is slowly polluting the air. The more electricity we use the more fossil fuels we have to burn. If we waste electricity it could be harming the environment.
How does the electricity damage the environment?
using energy more effciently through more effcient generation, such as combined heat and power ,reduces the amount of fuel required to produce a unit of energy output and reduces the corresponding emission of pollutants and greenhouses gases.
