$this->bbcode_second_pass_quote('John_A', 'T')he only explanation for why peak oil has latched onto EROEI that appears to make sense is that some require a veneer of science to try and counteract the appearance of blind faith in the concept. Real, live, critical thinkers who bought into peak oil hard, after some years of things just not working out as they were supposed to, figure out this for themselves. To them, it is not just blind faith, and they react accordingly.
ENERGY makes life easy and comfortable. Because it does the WORK for you. WORK you otherwise have to do YOURSELF. You know, shoveling, cutting, plowing, etc.
Energy that has > 1 EROEI is called a SOURCE. Energy that has < 1 EROEI is called a SINK.
There must be at least ONE source to supply the ENERGY to do WORK.
IF coals and oil and gas become SINKS, then obviously some other energy must be the SOURCE to provide the energy for those SINKS.
So I repeat the question. What do you think is the SOURCE to supply the energy once oil, gas, coal become SINKS. Solar panels?
You understand the problem, right? Oil and gas and coal are the PRIMARY SOURCE of energy, meaning they supply about 90% of the planets energy use.
So even I the world wants to buy 80MB of oil /day and the oil is produced at a miserable EROEI of 0.5, where does the energy come from to make it happen?
You got a cheap source in the works in your basement?
Holy shit is it really that difficult?
