There might be something to that!Except that it's incorrect. Solar is poised to knock most other renewables into a cocked hat.
There was a programme on one of the science channels on TV recently about a company in the USA that is also making paper-thin solar panels containing fullerene that are very efficient and will only get cheaper and cheaper with mass production.
Oil, gas and coal will never get cheaper again - apart from temporary dips - but solar panels will probably go the same way as computer and other electronic equipment.
My first computer - with 64 kb RAM - cost nearly 3,000 - a lot of money in those days. The latest one has over 1 gb and cost 340.:lol:
