For all that expense with fracking it still beats the snot out of solar and wind. Until we get over the hysteria around nuclear fossil fuels are going nowhere.
A real game changer could be a discovery in electrical energy storage. Even out the peaks from solar/wind. Solid chemical batteries aren't doing it - there's some cool stuff going on with liquid electrolyte batteries in Australia but I don't think the capacities or efficiencies of them can still beat out fossil fuels.
Now, if they could make these for 2000-3000km flights and they ran on 250kWh to 350kWh electric they'd be what the future entails. Especially if they weren't piloted and were fully automated.
And can we stop giving elon musk credit for everything? Tesla employs 48,000 people and contracts god only knows how many. It's pretty clear that elon musk is stealing credit for everyone's work, and Im sure the rest of the company physically cringes whenever people say stuff like "Elon is doing great stuff with batteries"
And when it comes to EV batteries, Tesla is leading the field. 21700 batteries are a smart improvement over 18650 cells.
And I'll happily give the engineers at Tesla credit. However, realistically speaking they should be branching out and applying the same technology elsewhere. Especially in regard to hybrid vehicles.
It's not an either/or situation. We can eat our cake and drive it halfway too.
Plus, the oil crash is still coming. Fracking has delayed it for a short time, and the covid lockdowns also have slowed consumption, but it is still inevitable. Before fracking, the U.S. army expected peak oil to happen sometime around 2015. Keep in mind, fracking is less efficient than old methods of oil extraction, and produces fewer barrels for the same amount of energy, and the energy for that extraction process comes from... oil. So we're burning the house down from both ends. Airlines don't stand a chance, in their current form.
