Do you still live under the delusion that what you pay and what cost the company have are somehow connected?
Not in the electric power industry.
But you think that they do in other industries?
Yes, in less-regulated industries, they do. In a competitive industry, you would generally expect that products that cost less to provide have a lower price.
Interesting that you think that. That's not my experience. You charge what your competitors charge, more or less, depending on how you position yourself. Lower cost to provide means more profit, not lower consumer cost.
The same is true in the power industry. Large consumers get better deals. You're not a large consumer, so they charge you whatever they can.
They charge me the price the State compels them to charge. They have no leeway.
Your prices are set by the state? Really? Where do you live? I get to choose which company should exploit me, and they set their prices according to "free market principles" meaning that they collude to skin us all.
How do you know it's inefficient? The government has successfully managed to create a village that is self sufficient and given incentives to others to break free from the power companies. Yes, it's a shame that the money instead isn't in the pockets of the power companies, where it would do so much more good.

I know it's inefficient because if it was efficient, it wouldn't have had to be compelled. If the prices they were getting for electricity were negotiated prices rather than compelled prices, they would be operating at a loss.
They probably would operate at a loss if the prices weren't set by the state. That's because power companies doesn't like competition. They have no incentive to allow this, and every reason to resist it. That doesn't mean that it's inefficient, it just means that power companies like profit.
The right way to deal with global warming is to become so smart and rich that we forget it ever even was an issue. This is the same way the human race has solved every problem it's ever solved.
That brings us back to how we find the next Einstein/Beethoven then? How to provide education and a level playing field for all so that everybody can reach their maximum potential. Except we should only look after ourselves, unless we feel a little charitable around Christmas and donate a little to some poor fellow.
If you're going to do it by forced central command, taking it from one person to give it to someone else, you will almost always wind up doing the opposite of what you want to do. In general, people wind up with money because they are being productive. Forced, centralized redistribution is not the way.
In general people end up with money because they have money. If not forced, centralized redistribution (aka taxation) is the way, then what is? How do you level the playing field and make everybody reach their full potential? Being born poor is having the deck stacked against you, some overcome that, but most don't.
