Like it or not, electrification is the future. Maybe not today or tomorrow but eventually. Associated costs will decrease as economies of scale are achieved, just as with everything else. And the internal combustion engine will become a relic of the past. Pound for pound, the output of electric motors far exceeds that of IC engines. And it’s available on demand, no need to hit the “power band”. In fact, acceleration has to be governed in order to prevent damage to the drivetrain and/or maintain control.
Solar energy is the future. Our sun produces somewhere on the order of 3.4 yottawatts in perpetuity. That’s a million, billion, billion watts or 1W x 10 to the 24th power. Constantly. And it’ll be here long after we’re gone.
For ***** and giggles Google “Kardashev Scale”. According to this theory we are a type 1 civilization. Which means we’re still diving for energy.
For even ***** and giggles Google “Dyson Sphere”. All we need for this is to create self-replicating autonomous robots which is not as crazy as you might think.
