If I were advising the UK Prime Minister, I would tell them to make a televised statement to the nation tonight (or very soon) along the following lines: 1. We are in an energy crisis. This crisis is having a dreadful effect on everyone’s finances. And it is going to get worse.

Controversial opinion, but I think February is an underrated month. It has the biggest start-to-finish improvement of any month imo. It starts off in absolute deepest winter, and by the end you’ve got snowdrops and daffodils, birds singing, sunset just before 6pm.

5. In the face of this crisis, I can assure you that the government will put in place huge support this winter. I don’t want anyone to go without heating or electricity this winter. But in return, I must ask you, if you can and it is safe to do so, to USE LESS GAS this winter
19
58
1,268
2. The crisis has been caused by huge rises in the price of gas. Much of that is down to Russia’s illegal invasion of Ukraine; we must continue to fully support Ukraine. The crisis is global. The government will take serious and urgent action, but we can’t make the crisis go away
109
65
1,221
6. This crisis is grave, but the rewards for tackling it will be great. By not relying on gas, we can make our energy at home, not rely on the likes of Putin. We can build a stronger, cleaner economy. We can tackle the climate crisis and leave a better world for our children.
32
55
1,122
3. What the rising gas price is telling us is that there is no longer enough gas to meet what we currently use in the UK. We don’t know how long this will last, but it could be some time; years, not months. We need to plan on the basis that it will last several winters at least.

But we will need your help. If you can better insulate your home this winter or beyond, please do. If you can make your boiler and radiators more efficient, please do. If you can safely turn your thermostat down, please do.

The government will set a target to reduce our gas use by 10% this winter, and by 20% before next winter. We will provide detailed advice in the coming days about how we can do that and how you can help. We will set the many skilled energy workers in this country to this task.
19
40
957
4. We use gas for three main purposes: - Heating our homes - Generating some of our electricity - Producing industrial goods. As well as affecting household finances, the crisis is also hurting businesses, and we must protect them as we did through the Covid crisis.
12
52
947
To try and maximise political consensus, I’d add: We will pursue all avenues for increasing our gas supply, both in the UK and with our international partners. But the truth is that there isn’t enough extractable gas in the ground to resolve the crisis, certainly not quickly.

For the avoidance of doubt: there was never a policy to “rip out” existing gas boilers. The 2035 phase out date is about stopping *new* boilers being installed.
For a family living in a terraced house in Darlington, the upfront cost of a heat pump could be around £10,000. So we're giving people far more time to make the transition to heat pumps. We’ll never force anyone to rip out their old boiler for an expensive heat pump.

This is a good question. Why have heat pumps become a bit of a contentious topic in the UK? I'm late to it, but wanted to have a proper go at answering it... 🧵
I'm proper fascinated by how the general vibes around heatpumps in Britain became so negative (at worst) or indifferent (at best). I am hugely sceptical of the top answer I've been given (right wing media bias and an anti-expert society) by most people I've asked about it.

Just to explain roughly what has happened with Thames Water: - After privatisation, water companies took on a lot of debt (mostly to fund improvements to water infrastructure pre-2008) - That made them v sensitive to interest rates - if you borrow lots, high interest rates hurt
This sounds like another textbook example of a company totally unprepared for higher interest rates. Particularly unforgivable given it made huge profits on the back of very low interest rates. Raising water bills to bail it out sounds unthinkable, to be honest

The UK’s economic outlook looks bleak - we are heading towards a very bad winter, a bad 2023 and beyond. But let me try and plant a few tiny seeds of optimism. This crisis could help us escape the last crisis: the cheap money, low growth nightmare of the last decade…
The BOE’s base case is circa 10% inflation for the next year or so, a recession broadly comparable to the early 1990s recession, rising unemployment, a sizeable two year fall in real household incomes and higher borrowing costs.

Cutting heat pump subsidies just after they’ve launched would be a disastrous policy. Many heating engineers and companies have invested in installing heat pumps. Pulling the subsidy now would hurt the industry and might make it impossible to grow again in future.

VERY significant for fans of electrification and heat pumps. The electricity to gas price ratio will be about 3.3 under the price freeze. That means a heat pump will be cheaper to run than a gas boiler as long as its efficiency is above roughly 2.8. Good news

Ok, I did “why the renewables auction went wrong” last week. Now here’s a thread on why I think it’s such a big problem. Tl;dr - we need loads more cheap, green electricity to do lots of the other bits of net zero (electric vehicles, heat pumps, industry).
The economics of renewable energy is confusing - and I’m not sure journalists all explain it correctly. So here’s a thread to try and explain what these renewables auctions are, why they’ve previously been successful and why the latest one went wrong…

OK, I'll bite... 1. "Why are you making companies sell boilers no one wants?" You know the answer: we have to tackle climate change. Gas and oil boilers make up a big share (c.15%) of our carbon emissions. So we have to replace them with low carbon alternatives.
This is nuts. Nobody wants to buy a heat pump, so the government is forcing boiler companies to make them anyway, or get fined for making the boilers people actually want.

Heat pumps do work in older homes, actually. We asked people who have installed heat pumps whether they preferred it to their previous heating system. Older homes scored just as well as newer ones. 83% of people in pre-1900 homes were as satisfied or more with their heat pump

That throws up many problems - interrupting the UK’s supply chain, slowing down the journey to net zero, meaning our dependence on expensive and volatile gas will go on longer. But it is hopefully also something we can fix, quickly. <end>

Renewable energy - particularly wind - is very different to traditional fossil fuel energy. Almost all of the cost is the upfront capital cost (I.e., building the wind turbine). Once you’ve built it, the energy is virtually free. For gas (CCGT in the chart), fuel is the main cost
18

This is a total storm in a tea cup. People typically replace their boiler every 15 years - so £120 is less than £10 a year. Meanwhile, our dependence on gas has raised typical energy bills by almost £1,000 a year. That’s the real issue, and it’s not gone away
Another 2 firms today confirm to @LBC they will increase the price of boilers as a direct result of the government's clean heat market mechanism, which will come in on Jan 1. For every target heat pump not sold they will get a fine of £3k, like those on electric cars coming on same date. But EVs, unlike heat pumps, appear to be a lot further along in the transition... Not great in a cost of living crisis to be raising prices for a market that's not there (yet). Worcester & Bosch: "To continue as a business we are regrettably forced to pass these fines on to the market in the form of a CHMM levy on every one of our gas & oil boilers. The increase is £120 per boiler in year one of the scheme, exactly equivalent to the CHMM requirement." Valliant: "Given the changing market dynamics and push for heat pump installations generated by CHMM, we in the current circumstances are left with no option but to act... from January 1st 2024, Vaillant will introduce a CHMM levy of £95 on all boiler sales under 70kW." Mike Foster of the EUA: "Entirely as the Minister was warned, that fine (in the form of a boiler tax) is then going to be added to the price of gas boilers. Over the last week, we have seen all four of the large British boiler makers issue warning notices to the market that boiler prices are going to be increased. If people want to buy a heat pump, our manufacturers will sell them one. But if they don’t want one, and they aren’t yet compulsory, consumers will pay the new boiler tax to the government if they replace their boiler."

This is *such* an important point. Baumol’s cost “disease” cuts two ways. It’s annoying for businesses / employers because it raises their costs per unit of output. But it’s great for most workers / people, because it shares the gains of productivity growth across the economy

The obvious solution, you’d think, would be to raise the CfD prices a bit (using the auction to still get the best possible prices). Yes, renewables would cost more, but it would still be cheaper than the alternative - using more gas. Unfortunately, this is not what happened

That poses a problem for developers of renewables projects. Who would spend hundreds of millions or more on some kit if you don’t know what price you’ll get for your electricity? (When renewables take over the grid, the price of power gets very low - such as this time in July)

Tom is, I’m afraid, right about this. The electricity-gas price ratio is too high. This is a profound policy failure, which makes it much harder for our economy to switch to clean electricity. But, fwiw, I’m optimistic that the ratio will fall substantially over the next 5 years
Replying to @thomasforth
Octopus have just given me their new costs. Electricity is now 3.9x the cost of gas. A much higher ratio than I'd expected. That still feels too high to make getting a heatpump a sensible thing to do. Or am I misunderstanding something?

The way CfDs work is pretty simple. If the market price is lower than the CfD price, the renewables get paid a subsidy to make up the difference. If the market price is higher, the renewables pay back the difference. The total is then either taken off or added to energy bills

It got to the point where CfD prices for renewables were generally expected to be cheaper than market electricity prices - so renewables would save us money. This policy was all going very well - big growth in renewables, cheaper electricity, lower carbon emissions…

Lots of excited talk today about nuclear and about renewables having low periods. Lots of people jumping to single, exciting solutions or sweeping conclusions. So here’s a thread on electricity, and why it’s not as simple as just building more of <insert your favoured solution>

On the one hand, this made the CfDs an even better deal - with the market price of electricity higher, those low CfD prices were set to save a lot of money. But on the other hand, higher costs meant the CfD prices were now too low to be attractive to investors

*Economic history animation* How many hours we worked per week, and the population of England, since 1270. The weekly hours go up and down, the population sideways.

There are 3 main things that have got us where we are: 1. Too little water company investment in sewerage infrastructure to reduce sewage overflows 2. Underestimating the cost of capital (interest rate), which let water companies make too much profit 3. Underfunding regulators

In the future, we’re likely to have periods with a massive surplus of green electricity (due to the variability of renewables). What’s the most interesting work on the economic opportunities of this? Can we, for example, run lots of desalination plants with the surplus energy?

Adding a thread with a few other explainers on the energy crisis…
Here’s a thread with some explainers I’ve done on aspects of the energy crisis. First, on why government can’t just make the energy crisis go away through taxes / price controls (because 60% of our gas is imported)

Ooh this is very helpful. The Parliamentary Office and Science and Technology (@POST_UK) have written a very good briefing note on heat pumps. Suspect this will be a very valuable reference document… post.parliament.uk/research-…

We need to talk about the impact of higher interest rates on Net Zero. Net zero requires big investment - in renewables, electric vehicles, industry, heat pumps. The irony is: we were slow to ramp up these investments during a long period of cheap money, and now it’s over.
Great piece by @JohnSpringford. Rising interest rates are a problem for net zero. Governments should respond.

I can only see two plausible reasons for this mistake: - Either a civil servant has had a bit of a laugh - Or these policies have been written within a small circle around the PM I guess it’s possible DfT officials made a huge mistake, but more likely they didn’t see it properly

How much does the UK need to invest in its electricity grid? How does that compare to Victorian investment in the railways? From what I can tell: - The UK invested ~2% of its GDP in building railways from 1845 - 1870 - We need to invest 0.2% - 0.5% of GDP in the grid to 2050

What the UK govt then did was to invite bids for CfD prices. Renewables projects could bid for a CfD price, and the lowest prices would be selected. This auction approach helped to drive down the cost of renewables over time - until the energy crisis carbonbrief.org/analysis-rec…

Now for the optimism. First, this crisis is accelerating the energy transition. The single biggest cause of the crisis is high gas prices. The response is to switch away from gas / fossil fuels. More renewable electricity, more clean electric devices, more energy efficiency…

It would be a disaster if the costs of carbon capture at Drax are added to electricity bills. £1.7 billion is around £60 per household per year. Adding that to electricity bills would make decarbonising heating and transport even more expensive. theguardian.com/business/202…
