Is NG really over 5X cheaper than electricity? It seems like a NG genset that is better than 20% efficient wouldn't be that hard to build, yet I don't see people running their houses off of electricity that way.

In the US, natural gas averages $11.85 per 1,000 cubic feet. Electric averages $0.13 / kwh.

1,000 cubic feet of natural gas is a bit over 1 million BTU. That converts to 297 kwh of electricity.

that 1,015,000 btu costs:

$38.61 in electric

$11.85 in natural gas

So 3-4x rather than 5-10x
