Re: Graph of electricity

hi model,

It's not a great graph, is it.  A scale but no units and the axes aren't labelled either.

I think this is showing the amount of electricity used (by a large group of consumers) over a 24 hour period.

So for example, in winter, there's a big rise in demand at about 2200.  Lots of people turning on their electric blankets and making a mug of Horlicks perhaps.  Why there's a smaller peak at 0200 I cannot imagine.  Perhaps this is only illustrative rather than a real situation.

Re: Graph of electricity

Hi Bob

Did you see the label saying "Typical daily demand for electricity"?

hi Stefy

In England we have 24 hours in each day.  What about you?

Re: Graph of electricity

Us too. What does that have to do with anything?

Re: Graph of electricity

I was responding to your post 3.

I guess I've misunderstood you again.

I'm afraid English is only my first language so I have trouble understanding it.

"I think this is showing the amount of electricity used (by a large group of consumers) over a 24 hour period."

I just thought that you weren't sure of what the graph represents.
