Many new technologies need initial subsidies.
Domestic solar power was kick started by a feed in tariff of 43p per kwh. This is now 4p per kwh and likely to be stopped completely. It prompted a massive increase in PV capacity by reducing the unit cost of systems over time. PV systems are close to the point at which they need no subsidy to justify their installation.
The same may be largely true for EVs - initial subsidy and increased volumes will make them cheaper and better. The subsidy will be withdrawn eventually as the cost falls. If volumes are high enough ICE will be mandated off urban roads as there will be a viable non-polluting alternative.
It's only worth subsidising a new technology if it is properly green from start to finish, which EVs patently (currently) are not. As I've said in other (similar) threads, we shouldn't be subsidising the (already) rich (making them even richer and more powerful) out of taxation mainly of those who aren't.
It doesn't help that very few people on lower incomes will be able to benefit personally from this due to them not being physically able to have charging points installed at their home.
As has been said, the Drax power station issue is a disgrace, and also many wind farms get paid when idle, seriously enriching their owners whilst (and with PV farms) blotting the landscape and (onshore) reducing the land available for farming.
We need to be careful not to subsidise everything that is new and ad-infinitum - in many ways it can stifle innovation because (if set too high) allows firms to make too much money early on in the development phase (which most green tech is still in) and not invest in innovative new tech that would mean subsidies are not needed.
Why is it that government subsidies for home PV panels has effectively ended, but commercial ones and wind turbines still do, especially as both can never be used to form the grid base load because one only works when the sun is shining and the other is highly variable, including not being able to generate electricity when the wind is too strong (not as high as you might think)?
