There is about no way what you wrote can possibly be true; with 5x efficiency gain we wouldn't need a mountain of EV subsidies to get companies to manufacture them and people to buy them.
If there was a net energy gain going to EV, the adoption rates would be through the roof rather than ~1% we are seeing currently.

- JumpCrisscross 4y agoThis compares gas -> motion with battery -> motions. To close the loop, we’d have to incorporate the generation efficiency. That will still yield an impressive number, but not 5x.
- onlyrealcuzzo 4y agoSolar => Car battery you only lose about 10% of energy. You lose more than that in refining oil to gasoline. And a lot more when factoring in extraction + transportation + point of sale. Closing the loop makes solar => car even more efficient, not less. Sure, if we want to be dumb and extract oil to power inefficient turbines to generate electricity this becomes a talking point. But not many people are building new oil power plants for a reason...
- JumpCrisscross 4y ago> we wouldn't need a mountain of EV subsidies to get companies to manufacture them and people to buy them The consumer captures these purported gains, not the manufacturer.
- ClumsyPilot 4y agothis is key- peiple often think market will just magically adjust to most efficient solution, bur incentives must alight. For example UK is one of the richest countries in europe, it has the most expensive housing in europe and it has the worst insulation in europe. Landlord has no reason to imprive insulation, the tenant pays for utilities
