Oh yeah, it’s inefficient as hell. But energy from the sun is coming to us whether we harvest it or not. It’s unlimited. The limitation is solar cells.
We’re at the point where we’ve basically run out of easy oil to access, and we’re coming up with bigger and deeper drilling methods. We spend billions on a single offshore rig that will function for 10-20 years at most.
The issue isn’t efficiency, it’s profit motive.
“very long time” here is like, 6 months to a year. Fuel does break down, a sad reality that anyone who has tried to start a lawn mower in the spring after letting it sit full of fuel all winter can tell you.
But! That is quite a bit longer than electricity, which needs to be used pretty much immediately or it’ll start blowing up transformers.
Logistics is the primary issue. We can’t generate power anywhere it needs to be pretty close to where it’s being used. Unless we want to ship giant fucking batteries all over the place which in some circumstances might not be a bad idea. Not ideal though. Still, if we’re putting biofuel on a truck, it’s worth considering. I’m not sure the energy to weight ratio of 80,000 pounds of batteries to 80,000 pounds of fuel is.
That said, we can build these things to make energy transmission possible over long distances. Shit if we’re making enough excess energy from solar alone we could beam it across the sky with microwaves if we really wanted to. The barrier here is not that it is hard. The barrier here is that liquid fuel is still so goddamn profitable there’s no incentive to switch.
We both grow more than we need, and throw more than we should away.
Some of that is a result of picky shoppers wanting unblemished produce. Some of that is a result of not having an
easyprofit motivated way of getting produce from where it’s grown to where it’s most desperately needed.We have tropical fruit available all year, but when impoverished peoples experience a crop failure, best we can do is send powdered milk.
Which incidentally may have cured them of lactose intolerance.
