wotfigo; Modern civilisation depends entirely on the two fundamental energy supplies notably, electricity & liquid fuels. There are many energy sources to produce electricity. But there are no substitutes for liquid energy. Liquid energy sources can include oil derivatives, and liquefied gasses. There are really no substitutes for liquid energy other than some possible conversion to electricity. We can convert a large part of our road transport infrastructure energy source from liquid energy to electricity. For example electric trains, electric cars, electric trams & buses. Even electric trucks. But it is not possible to convert our air or ocean transport to electricity in any meaningful extent. Also liquid fuels are the prime energy source in the farming, mining, & construction industries. Complete conversion to electricity is not possible without loss of energy output. For this reason it appears that the imminent decline in liquid energy supplies will mean a decline in the quality of food and goods & services in our civilisation. Human population is tied to energy sources. As the energy that powers our civilisation declines so too will our population. Let’s hope that the decline is as gradual as this graph depicts.
wotfigo. Graph; The light blue line is the oil & gas production which peaks before the year 2025 & then declines. The dark green line is the worlds population which peaks around 9 to 10 billion people in about the year 2050. Population then goes into decline following the loss of the hydrocarbon energy sources. This projection (& there are many others) predicts a low human population without hydrocarbon energy sources of only 1 billion people by the year 2200.
