Why do we pipe natural gas into homes?
puts on Technology Connections hat
because heat pumps and green energy weren’t a thing in the US until recently!
heat efficiency is weird. electric heaters are 100% efficient, but 1) they’re only as efficient as the generator, and 2) transmission losses add up. and until recently, most power was generated by coal and natural gas. turning those into electricity is lossy, since lots of energy is lost as waste heat. so why not send the gas you were going to burn for electricity directly to the customer?
heat pumps can be 300-400% efficient, since they move heat - from outdoors, into the home - rather than generating it. they can get >100% efficiency even in cold climates! but stupidly the US never bothered make our air conditioners reversible, or every home would have a heat pump by now.
and with solar/wind (for peak) + nuclear or grid storage (for base) power, we can now get rid of natural gas. …once we give everybody heat pumps. …and shutdown our gas generators. …we should probably get on that.

Another way to look at it: we’re already over the climate brink. Your future won’t have cheap/stable meat access no matter what. We can either clutch our hotdogs right up until supply chain collapse makes mass meat farming untenable or proactively discard them to make a slight difference (in conjunction with other big changes).

Same with cars, even if we completely ignore climate change we maybe got a century left of oil before it’s too expensive to drive. By not investing in other transportation now we’re just making it more painful when we finally do rip the bandaid off.

The water wars will probably kill us off before we run out of oil.
