And as if that was not enough to make any sane person stop and think, the solutions proposed by the Green Blob, apart from being so expensive they would destroy every functioning national economy on the planet, are going to be more damaging to the planet than continuing to burn coal and gas as our main source of energy and fuel out vehicles with oil. The Blob propose abandoning this reliable, consistent source in favour of intermittent, unreliable sources, primarily wind and solar powered generators. The Boggart Bloggers have written on the shortcomings of these technologies many times.
A small, clean, green, and utterly reliant on the vagaries of the weather, 100-megawatt wind farm needs 30,000 tons of iron ore; 50,000 tons of concrete and 900 tons of non-recyclable plastic.
For the same power from an ever-so-green solar farm you need to increase those figures by 150 per cent.
An battery pack for a small electric car weighs half a ton, to make just one requires the mining of 250 tons of bedrock somewhere on the planet, and the smelting and refining processes consume vast amounts of energy mostly derived from oil, natural gas and coal.
All these 'clean, green, renewable' methods of generation require what are called ‘rare earth metals,' which are actually quite plentiful but occur in such low concentrations that separating them from the ores in which they are found makes them phenomenally expensive, as well as resulting in vast quantities of toxic shite (including cyanide, arsenic, nitric and hydrochloric acid,) so a phenomenal 2000 tons of toxic waste is produced and most of it is dumped in the environment, just to produce one ton of the any of the rare earth metals needed to make wind turbines, solar panels or lithium ion batteries. On top of all this, processing and shipping is required to the developed nations, and this is usually provided from companies based in from unregulated regimes (e.g. Liberia,) with very lax environmental standards.
As mentioned above Solar and wind generation is limited by its dependence on weather conditions, another issue we have commented on many times, but we need energy ALL the time, so we have to have permanent back-up of a type that can kick in instantly because both cloud cover and wind speeds can change very quickly and it is not possible to turn a key or press a button and start a combined cycle gas generator they way we start our car or switch on the vacuum cleaner.
And then there is the land requirement because the amount of productive land lost to production of food due to the spread of 'renewables' is astounding.
To accommodate 2,000 MW of gas or nuclear power generation requires the same area of two 18-hole golf courses. Whereas, accommodating 2,000 MW of wind power requires an area the size of Belgium!
Then, of course, you still need 2,000 MW of gas or nuclear power to accommodate those hundreds of occasions each year when wind and solar power is producing absolutely nothing.
One of the proposed solutions is to build vast battery farms to store surplus energy when wind and sunshine give us a surplus, but apart from their not being enough known lithium reserves in the world to provide adequate backup for just on developed nation, a statistic I read recently claims the giant Tesla factory in Nevada would take 500 years to make enough batteries to supply the USA with electricity for 1 day!
After 30 years of development and countless billions of £$€ in grants, subsidies and incentive payments, wind
and solar still supply less than 5 per cent of the world’s energy. You may have seen screaming headlines in mainstream media proclaiming that on a particular day 'renewables' generated over 50% of the UK's consumed electricity, b.ut contrast that with the deafening silence when on cold, windless winter days when solar and wind between then provide less than 5%.
On top of that, in common with all technology, wind turbines and solar panels are built from non-renewable materials, and they break down, parts wear out or break and have to be replaced time and time again, so installation is definitely not a one-off cost.
