That's resistive heating, which is the most inefficient means of heating. Worse than natural gas or heating oil, and much worse than a heat pump.

Worse than a heat pump, yes, but very arguable whether NG is more efficient. Arguably, NG powering central electric power generation and then used for resistive would be overall more efficient. Central NG will be more efficient and also there’s substantially less opportunity for NG leakage if piping was reduced.

NG is definitely cheaper (at least in the US), but that’s not really related to efficiency or emissions cost.

It doesn't take into account leaks, but modern NG furnaces are substantially more efficient than modern gas power generation.

I’m not sure that’s easily quantifiable. Yes, thermal efficiency of modern NG furnaces can be ~95% or whatever… but you can also run multi stage heat capturing NG power plants that have very high overall efficiency too. Not 95, but at 60-70%, it’d be a potential wash in terms of emissions if leaks are ~10% (especially considering how much worse unburnt NG is as a leak vs when it’s burnt).

Also, if you’re in the electric ecosystem, swapping to heat pump systems will obviously be lower overall power in basically every scenario, and it gives an easy transition path unlike NG.

Maybe... I've got a NG furnace now and am looking at adding a heat pump, and even with a pretty expansive budget, I'm struggling to make the numbers work on actually removing the furnace entirely vs. doing heat pump + furnace. (And the near-impossibility of upgrading my home service past 100A makes it extra complicated if I want to electrify everything.)

I regret to inform you that Obama did not ban any light bulbs.

Those initiatives were legislated during the Bush administration in 2007.

They were rolled back some during Trump's first term, in 2019.

Restrictions were re-introduced under Biden, in 2022.

I don't care much on the politics of it all because I do think a lot of it is silly, especially with how profit-motivated companies will still find a way to profit.

I will say I've had a number of Hue bulbs starting back in about 2018 and have yet to lose one except for a surge that got an unprotected strip. Otherwise, plenty of white and color bulbs have worked steadfast for nearly a decade while costing a fraction in energy. That said, I do miss the warmth of incandescent lighting, but I don't miss replacing bulbs multiple times a year
