How does saving electricity help to save the enviornment in Canada?

Question

my friend just ask me this question..and i am curious too..so i look it up..and i find it is saving coal and the natural gas which are used by more than 70% of the world .(and I understand how this helps to stop the global warming)

but there are actually only 7.2%.who is using hydro to get electricity..(and apparently most regions of Canada esp.B.C are using hydro)..so how does this(like Earth hour, everyone shut down their light) help?

so my question really is how dose saving electricity

Answer 1

Power generating companies don't really generate a huge surplus of power, which would be mostly wasted (unless it could be stored, in batteries for example)

They usually generate to meet demand, and little more. A surge in demand too much above what is expected can cause problems.

If the demand falls (eg by turning off lights) then they don't need to generate such a high power output, and can burn less fuel.

Answer 2

I've never understood this either!

If we save electricity, are we doing it so that there will be more to use later?

And if it's true, as it seems you people believe, that making electricity in the first place, and/or using it is a bad thing, why do we even want to save it?

Doesn't saving it imply that we plan to use it later? What's the difference between using X amount now or later?
