If fossil fuels are rapidly eliminated during the transition to non-fossil energy, the pool of energy available to society will shrink. How much it shrinks will depend on how fast the new energy capacity and a new electric grid can be developed.
Here is how: in addition to your “climate strike”, or as a substitute to it if or when you get frustrated of being denied the kind of change you want, embark with all the strength and enthusiasm of your youth on an “energy diet”. A big, fat, relentless and endless energy diet. Not only on Fridays, but every single day of the week, 365 days per year, for the rest of your life.
