Get ready to be cold and poor in 2025

But then, don't you think the price of gas and oil might rise to persuade people to leave it?

Good luck getting re-elected to any Government who taxes mains gas to significantly narrow the gap with electricity.

Mains gas is 3.74p per kWh. Electricity is 19.88 per kWh (over 5 times more expensive).

If oil and gas prices rise, investment will flood into the sector, causing a glut and so lowering prices. Prices are ultimately determined by how expensive it is to produce and not by how much environmentalists would like them to be. Of course some countries may tax oil and gas, but that will just shift energy intensive industries elsewhere.

Whoever the government is is going to have to make some very big changes if they truly believe in climate change.
Heat pumps seem to use less energy to run than a gas boiler - I think I saw figures they are about 2X the running costs overall. Subsidies on green energy and/or carbon taxes could just about bridge that gap.

I'm sorry, have you bought any petrol in the last 20 years? Or cigarettes?

Sounds about right.

In order to swap our oil boiler, without changing any of the other plumbing, we'd need a combi heat pump solution which I don't think exists at the moment.

The technology is constantly improving and I'm sure the upfront and running costs will come down over the next few years.

Despite this small reduction, the much larger cuts for renewables mean onshore wind and solar are now expected to be half as costly as gas in 2025, as shown in the chart below.

its going down!

We still need to upgrade the grid to cope. Or use excess wind to create hydrogen.

I don't follow why, is there a reason you couldn't install a HP for heating and a standard electric for hot water? The energy you use on hot water is presumably relatively small by comparison to heating?
Actually combis seem to be out of fashion again. I remember they were all the rage 10 years or more ago, but now everyone is recommending pressurised tank systems and people who replaced their tank with a combi are switching back
Personally I like on-demand hot water but is combi a must for you?

It would involve a fair bit of additional plumbing work to install an immersion heater tank somewhere in the house.

The oil combi we have is an external unit (a couple of metres from the house), so it would be relatively straightforward to replace this with a heat pump if there was a combi option available.

Hydrogen is seen as an alternative to replace gas. ..

Holy carp! Gas explosions regularly demolish a house, but a hydrogen gas blast would take out the whole street!

Also, hydrogen leaks chronically, due to quantum tunneling. There isn't a thing one can do about it AFAIK

Blimey imagine if we captured the excess wind from this site! oh that would be methane

It's good for airships though.
