Also, I think this is the cost of grid electricity. I know in my part of the world, for example, some miners want to experiment with natural gas generators. Far, far cheaper, no one would plug into the grid!
Are those natural gas generators actually safe to operate with the amount of power being drawn, without being a fire hazard?
[that is assuming that you've found a dry place
outside to host it, as it is not safe to run a generator indoors, from what I have read.]
I've only seen one up close, but seen many models for sale only in Southeast Asia. China (duh) and Japan pretty much make hi-tech models, Japan buys gas from my island, actually we still produce way too much and it all gets burnt off (flaring), so demand still a long way off from supply.
They're always outside! Don't look much different from diesel generators, except you pipe in the gas from a separate canister unit (we don't have piped gas AFAIK in most of SEA).
