People that claim we can maintain our standard of living while switching from carbon to renewable energy do not know what they are talking about. There is no evidence or science to support their claim.
Renewable energy is not growing exponentially and is not replacing carbon energy. The industrialized countries growing solar energy the fastest (Greece, Japan, Italy) are the countries most likely to crash first into depression because they have no fossil carbon resources, cannot afford current energy prices, and have compensated with too much debt.
We can choose to voluntarily and peacefully reduce our standard of living now, or we can wait for nature to do it violently for us.
A voluntary economic contraction will also make climate change less bad.
