I would describe it as ample........we just have to work out how to get it
Our Sun pumps about 386 billion million gigawatts into space, mostly in the form of electromagnetic radiation. By comparison, a large nuclear reactor generates about 1 gigawatt, and global energy consumption is a few thousand gigawatts. This energy output is typical for a star in the same class as our Sun.

Every hour the sun beams onto Earth more than enough energy to satisfy global energy needs for an entire year.

Of course it doesn't matter where we get the energy from it all originates from the sun.
Not often i agree with you BF.
I believe there is a place in the world that produces the same energy from one solar plant, that would take about 10 nuclear plants to produce. Of course the powers that be would rather sting us with massive prices from oil etc.
A similar situation to cancer drugs, i believe that cancer can be cured using herbs, hemp oil, marijuana etc and the cure is being stifled because the drug companies don't want a cure and ruin their massive profits, but that is another matter.
By the way, before you think i'm getting a bit liberal or limp wristed....... i do not like Caroline Lucas very much at all.
