A good test is to turn off all the breakers in your home. Then watch the meter and make sure it doesn't still move.
Then start flipping breakers back on one by one and watching the meter. If its the old style dial it will be easy to see when something starts taking a lot of power. If its the digital meter you may need to wait 30 minutes to see how much it changes. You just need to see which breaker(s) cause it to use more power. So start with the ones you think are problems (e.g. A/C, hot water). But sometimes you might be surprised so get a good read for each breaker. Then for the ones that consume a lot start to turn stuff on/off that are on that breaker until you find the item that consumes a lot.
I had a refrigerator that went bad one time (not sure quite how) and it started using a ton of power 24x7. Fixed it and things went back to normal. That was years ago back in the States, but I identified it by doing this test.
