I have no clue about other countries, but the National Grid here generates different amounts of power based on the time of day. There'd be far too much power in the grid and money being wasted if they constantly made the same amount, so they don't. At night very little (comparatively) is being generated because not many people use power at night whereas after a football match or Eastenders they use lots. Likewise, I don't see why any other country's power grid would be much different since it seems to work well enough.
Where I live it is largely hydroelectric so it maybe different. That is how it was explained to me anyway. My be my teachers have been lying to me. Either way there are still peak periods that would serve the world better to be evened out to a nice flat line (not that its going to happen)
Nope, hydro is actually one of the best for adapting to peak demands. About a 4 second response time (which is v. good compared to coal-fired power plants). And they can also use excess power to pump water back up the dam, thus reducing the amount that's wasted.
