running out of energy is the best way to reduce population. the amount of kilowatts is directly correlated to the growth in population.
what i'm more concerned with is there is no preparations being made for the inevitable, and coming soon solar event that will not just render all of our transport, sanitation and food production systems inoperable, it will also destroy all the tools we need to recover from it.
if we don't get prepared by moving critical resources that the loss will destroy recovery capacity, underground, where they won't get fried by an X100+ flare, it's gonna be decades of respiratory disease epidemics in winter, and reverting to cooking with wood and international transport is basically over.
that's what i'm preparing for. i think that steam and diesel power can be sustained if you don't lose the tools required to forge steel and dig enough coal/chop enough wood to get that heat to drive the factories that will produce the higher levels of the market.
nothing is being done about this, while everyone is pointed at CO2 and methane, we won't even have cows to pull our ploughs if they have their way.
