At last - somebody who has crunched the numbers on what it will take to achieve all the legal targets that have been set world-wide to keep "global warming" within the magical 1.5oC, even assuming that that's what we need to do.
Can it be done?
"Current renewable energy systems generally have a lower Energy Returned on Energy Invested ratios (ERoEI) than current fossil fuel-based systems. They may not be productive enough to replace fossil fuels. As such, they may not be the energy foundation for the next industrial era, but a steppingstone to some other kind of energy generation system not yet identified"
How can we do it?
"This is actually a mining problem"
"There is no other source for those metals"
"The idea of being managed from a central point is almost never going to work"
"The system will have to shrink, and will have to become less complex"
