Regarding investments, we will need oil and coal long after I die. Can't get building materials from solar or wind resources; such as plastics, asphalt, paints, solvents, lubricants, fertilizers, transport fuels (especially planes and 'copters), etc. I'd say continue investing in oil and coal production.
Global cooling is coming.
Fortunately we have plenty of tech to keep drilling where it is quite cold and icy.
Petrochemicals will continue to be a large part of the Economy for Decades if not Centuries to come.
