"Cars will be electric, trucks will be electric and busses too and our homes will be powered by electricity from onshore wind. Offshore wind, solar, tidal and wave generated electricity. Green hydrogen will be developed to allow its use in various modes of transport and battery storage will likewise be developed and refined."
Yes, sounds great, doesn't it?
But wrong.
Hydrogen - regardless of the colour - is not cheap or simple to produce, transport or store in quantities large enough to be of any practical value. It only occurs naturally in compounds such as water. It is highly inflammable, the most combustible gas there is. That's why they stopped using it in airships. Just producing enough to power a small gas turbine, after mixing it with natural gas, would cost more than the saving made. So hydrogen is a non-starter as a mainstream source of power. Similarly with battery power. Great idea but production is hugely expensive and the rare earth metals required cost fortunes to mine. Again, not suitable for industrial or domestic use.
Wind turbines? OK for producing a small percentage of the national grid output but to replace coal, gas or nuclear power there would have to be wind farms on every street corner and that's not a viable prospect. They produce electricity for nothing, yes, but they are still less efficient and costly to run than a power station. Same goes for wave power. Solar power is great as long as the sun shines, completely useless in the dark. Storing electricity isn't a cheap option either. A capacitor with enough storage capacity to power the average house would be as big as the house and a battery with sufficient power to drive all the household appliances, heat the water and keep the lights on doesn't exist.
As for electric cars, lorries and buses, these will only replace the combustion engine when battery technology has improved to the point where they are viable on a cost basis and that is years away, if not decades.
The green lobby are witless charlatans who believe in fairies.
