My reference to little green bottles is a song Little Green Bottles
hanging on the wall.
You said;
Solar has a life of it's own and unstoppable, with no maintenance
and gigantic guarantees it's a winner for all owners of an array.
That is fine except that all those enthusiests never take into account
the one thing that makes solar and wind a failure.
Energy Return on Energy Invested.
Forget the money that is not relevant.
If it takes more energy to build, install, maintain than the energy
produced then it is a failure.
Anything with an ERoEI less than 7 is considered to be a failure and
a waste. Wind is marginal at about 10 and solar a failure at 4.
However if you add backup to the system then the ERoEI falls to
fractional levels with solar at about 0.4 and wind about 2.
You must have backup because the wind is often very light at night.
We all know you can build bigger and bigger systems but because of
ERoEI they cannot even build a new energy regime just using solar & wind.
This is the crunch point, we must have a new energy regime but at
present we only have coal, oil & gas to do the job.
Without a new regime, whatever it is, we will be back in the middle ages.
Back to politics, neither party is prepared to face the above reality
even though they have been told. They know better don't they !
