| They don't have a choice. They can die or try to survive and likely die anyway. The CO2 emissions will be gone by 2050 even if it has to happen on the corpses of Shell, BP or Exxon. The world needs to shift the production power away from oil into renewables. > Just the input energy that would be required to build everything would be immense, and I don't think we've got the production capacity for solar cells or the raw materials to do it either. We can do bigger things than that. We need to create that capacity - grow it exponentially. I think you are seriously underestimating the capacity of human civilization once we decide to do something collectively. Vaccines normally were taking 20-30 years to reach market. Due to COVID we started vaccinating the world in less than a year. If there is a will there is a way. From MIT report "The Future of Solar Energy" https://energy.mit.edu/wp-content/uploads/2015/05/MITEI-The-... > There appear to be no major commodity material constraints for terawatt-scale PV deployment through 2050." > PV modules will become a major driver
of flat-glass production at high solar
penetration levels, but the availability
of commodity materials imposes no
fundamental limitations on the scaling
of PV deployment for scenarios in which
a majority of the world’s electricity is
generated by PV installations in 2050. > Required growth rates for silicon and silver production
fall well within the range of historical growth rates,
even for 100% silicon PV penetration. |
