The aliens told the world government that if we prove we have eliminated the use of fossil fuels, they will provide the energy source that powers their craft.
Perhaps it’s the off-world aliens that are driving all these lunatic fringe social and political agendas.
Climate change, gender fluid, anti-energy, pandemics, anti-religion, anti-family, anti-human....
Starting to sound like something a hostile alien invasion would cook up to soften the target.
No, FAR more likely, in such a scenario it would be governments withholding free energy, among other things, now that I think about it.
