What is one environmental advantage to turning off electrical appliances when they are not being used?
Yes, a lot of electricity is used up needlessly because people leave appliances plugged in.
It's not good for the bills, it's not good for the environment, it's not even good for your appliances... Phones and laptops that are left on charge constantly always have a shorter life span.
I think turning off electrical appliances is a good habit because the electrical appliances produces harmful gasses and it affects the ozone layer. (Harmful gasses-carbon dioxide, sulphur dioxide etc...)
