I'm wondering how much power (electricty) and coal used to produce that power China would conserve?

I ask this question because the recent storms China suffered caused a huge reduction in coal supplies for many cities. It got so cold in places that aren't normally cold that many places came close to running out and coal miners had to give up their Lunar New Year holiday to work overtime to keep the country supplied with this horribly dirty fuel for their power plants and the government heating system. Perhaps if the normally cold places of China weren't so wasteful of it's electricity and heat, China wouldn't need to produce nor burn nearly as much coal as they go through every year.

Gengi, radiant heat here is hot water pumped through pipes, or essentially a radiator, in the walls. My school put in an additional boiler system because by the time the water get up the mountain to us it's no longer hot. Thus, the school uses more coal-fueled electricity to heat the water so we have some heat. It's still not enough. Most of us have had to buy extra heaters to keep our rooms warm enough to keep us healthy.
