The phrase "renewable energy" is one intended to confuse. Energy is not a thing, it's a flow - it flows from higher concentrations to lower. Chiefly on earth the energy we have access to is solar energy which flows from the sun to dissipate at the background temperature of the earth. It's a one way trip and can never be renewed. What people are really talking about is stored solar energy (fossil fuel) or the real time flows of solar energy. The latter is what humans have always had access to, while discovering and learning to use the stored energy of fossil fuels is what allowed our industrial society and the present population.
great points...all true to a point...
....not all oil is solar based biomass. some looks to be from whatever/however the geo-moments/events that are active under the surface....
that, to the point we only know one thing for sure..... we have no fuking idea how it is made or what it actually is.....
stored energy from the massive geo events i feel safe to assume... so to your point. its stored already. but not directly bio based.
based on the rock and carbon cycle events i was taught...
oil is dino juice
coal is a newer version closer to surface still under the cycle....dont know how that explains all of the fawking surface oil we mopped up...but just to be easy we wont go there..........
so is it....oil in general... really old coal crushed way way down coal made from plankton.... kelp forests and surface air forests and boggs ect... how it got down there 5 miles away....i dont even want to know anymore.
i just drill the fawking holes to go get it.....but in the 30 years i have been doing this shit...the reality does not line up with the bullshit they taught me in school. especially on formations...
what i do know....is the roof surface on my house is more then enough area to power my needs via the recent delivery via photon that day...combined with capacitor based/battery storage...which pulls it off for the night.
there are people doing this right now..... not tech available in ten years....tech that is 15 years old today.
its not easy...
and its not cheap.
but at 180-200 bux a barrel for oil in todays dollars...it is easier to see it as doable.
and it sure as hell will power up a tesla in just an hour or two.
