Now I'm not a fan of gas engines, but that argument is in bad faith. Gas engines have one very big advantage over electrics: Energy density, and by extension, range. Batteries can't come close to the energy density of hydrocarbons, despite the latters' overall lower efficiency. --Coconut Galaxy (talk) 17:22, 19 June 2024 (UTC)

I think that's one of the main arguments for hybrid systems. Using a gas engine to charge an electric motor, and then using the electric motor to actually power the appliance, enables significant efficiency gains. If anything, combining the technologies enables even greater usable energy density from hydrocarbons. Hybrid electric vehicles for example are extremely efficient.

Plug-in hybrids have been superior since 1904, but the incremental capital cost is still an issue while oil is under $100/bbl. 172.71.150.129 19:16, 19 June 2024 (UTC)

On the other other hand, in a lot of cases an electric motor is just a gas engine with extra steps due to the current state of the power grid. 172.68.174.232 17:24, 19 June 2024 (UTC)

I'd say an electric motor powered by a hydrocarbon grid still usually makes better use of gas than a typical gas engine. Gas engines that don't always run at full throttle (as in, a gas engine in an appliance) have dramatically worse efficiency than electric motors that don't always run at full throttle. It depends very heavily on use case, though; always take measurements and run the numbers before coming to a specific conclusion. Science would be nothing without empirical data.

Should this have Category:Climate change? I can’t decide. Usb-rave (talk) 17:40, 19 June 2024 (UTC)

Yeah, it's better with it for people looking though the category later on, they will want to see it. 162.158.186.10 19:13, 19 June 2024 (UTC)

Honestly, with this argument the thing has engines have going for them over EVs is the refueling time and availability. 172.69.59.175 18:58, 19 June 2024 (UTC)

It's really remarkable how uninformed and unintelligent this comic is, to the point where I now doubt the veracity of his entire What If? series.
