We need the fossil fuel industry to fail, not want. It got us here, but is no longer required, and actually costs more than alternatives. The problem is the momentum the industry has.
you dont know what the future needs of society will be. eg there are ancillary techs associated with all types of energy that may become useful in the future.
I do though. We know that climate change will be a problem. We know it will cause massive future costs. So the longer the fossil fuel industry stays the more future debt we have.
