When I look at this chart [0], seeing that we’re wasting about 2/3 of our energy, I expect the energy demand to drop significantly if we electrify everything and have more local energy sources.

- apatheticonion 5y agoThis is a good point. Seems like there is reason to be optimistic. I certainly think it's possible for the US to be carbon neutral by 2050 - but ya'll better start banning gas cars sooner rather than later (seeing as modern cars will last 20-30 years).
- ahartmetz 5y agoNote that much of the waste probably comes from thermal / fossil power generation, which is unavoidable even in theory (cf. Carnot efficiency). That is, unavoidable unless chemical energy is turned into electrical energy directly like in fuel cells (these have smaller but still surprisingly large losses), or the rejected thermal energy is used for heating.
- hebrox 5y agoWith local energy sources, I meant, local renewables energy sources. So no chemical energy.
