Misinformation about the UK's energy system is spreading rapidly across social media, newspaper opinion columns, and political messaging. These narratives shape public opinion, deepen division, and obscure the real structural issues driving high household bills.
Here we break down the most common claims, examine what the evidence actually shows, and outline the opportunities the UK is currently missing.
Key Takeaways
- Domestic extraction does not lower household bills - UK oil and gas is sold on global markets at global prices
- UK geology makes large scale fracking high risk and low yield - the US comparison does not hold
- Renewables are not the reason bills are high - the electricity pricing system is
- A modernised tariff system could dramatically reduce costs for households
- Publicly owned renewables could create competition, stability, and long term national benefit
Claim 1: "More UK oil and gas extraction will lower household bills."
What the claim suggests
That increasing domestic extraction will reduce reliance on imports, lower wholesale prices, and translate into cheaper household bills.
What the evidence shows
- UK oil and gas are extracted by private, for profit companies, not the government.
- These companies sell into the international wholesale market, where prices are set globally.
- The UK's share of global production is too small to influence global prices.
- Even doubling UK extraction would have a negligible effect on international wholesale prices.
- Household bills are tied to global gas prices, not domestic extraction volumes.
The Bottom Line
Increasing extraction increases corporate output, not domestic affordability. The UK remains exposed to global volatility as seen during the Russia–Ukraine war and more recent geopolitical tensions in the Middle East.
Claim 2: "Fracking works abroad, so it should work in the UK."
What the claim suggests
That the UK could replicate the US shale boom and unlock cheap domestic gas.
What the evidence shows
- The UK's shale geology is highly fractured, unlike the large, stable shale basins in the US.
- This increases the risk of induced seismicity small earthquakes triggered by fracking operations.
- Offshore fracking in the North Sea would carry additional geological and operational risks, including the potential for induced seismicity in areas connected to coastal regions.
- Even if technically feasible, UK fracking would produce limited volumes relative to global supply.
- Small volumes cannot influence global wholesale prices.
The Bottom Line
Fracking is not a scalable or low risk solution for the UK. The geology is different, the risks are higher, and the potential output is too small to shift prices. The US comparison does not translate.
Claim 3: "Renewables are pushing up electricity bills."
What the claim suggests
That green levies and renewable subsidies are the main reason household bills are high.
What the evidence shows
- "Green levies" and Contracts for Difference (CfD) payments are not the primary driver of bills.
- Over 40% of household electricity costs come from the marginal pricing system, where the most expensive generator usually gas sets the price for all electricity.
- When gas prices spike, all electricity prices spike even cheap wind and solar.
- The UK's reliance on imported gas makes us vulnerable to global shocks.
The Bottom Line
Renewables are not pushing up bills. The pricing system is. The UK is paying gas based prices for wind based electricity.
Understanding the UK's Outdated 30 Minute Pricing System
To understand why bills remain high even as renewables grow, it helps to understand how electricity is priced in the UK.
How it works today
The UK electricity market is divided into 48 half hour periods each day. In every one of those 30 minute windows:
- Generators bid to supply electricity
- Bids are stacked from cheapest to most expensive
- The last generator needed to meet demand sets the price for everyone
This "last generator" is usually gas, because gas plants can ramp up quickly to meet demand.
Why this keeps bills high
Even if most electricity in a half hour period comes from cheap renewables, if gas is needed for the final few percent, then gas sets the price for 100% of the electricity. All generators get paid the gas set price, and consumers pay a gas linked price even on windy days.
This is why global gas price spikes instantly raise UK electricity bills, regardless of how much renewable power is on the grid.
Why it's outdated
The system was designed for a fossil fuel heavy grid in the 1990s. Today, renewables are often the cheapest source of electricity but the pricing model prevents their low cost from reaching households.
Current System
- Gas sets the price for all electricity in each half hour window
- Consumers pay gas linked prices even when most power is from wind or solar
- Global gas shocks instantly raise household bills
- Renewables cannot compete on price under this model
A Reformed System Could
- Give renewables their own tariff, reflecting their actual low cost
- Price gas separately from cheaper generation sources
- Let consumers benefit from genuinely cheap wind and solar
- Reduce exposure to global gas price volatility
The Structural Issue, The UK's Outdated Pricing Model
The core problem is straightforward, all electricity is priced according to the marginal generator. Gas is often the marginal generator. Therefore, gas sets the price even when wind or solar are generating most of the electricity.
The consequences of this are significant:
- Consumers don't benefit from the low cost of renewables
- Renewable operators don't compete on price under this model
- Gas volatility becomes system wide volatility
A Better Alternative: Let Renewables Compete
A modernised pricing system could fundamentally change the economics of household energy. By giving renewables their own tariff that reflects their actual low cost, and pricing gas generated electricity separately, consumers could choose tariffs based on energy mix rather than a blended price that always defaults to gas.
The potential benefits are substantial:
- Lower bills for households
- Greater transparency about where electricity comes from and what it costs
- More competition between generators
- Reduced exposure to global gas price shocks
- Faster decarbonisation without higher costs
The Missed Opportunity: Publicly Owned Renewable Power
Beyond pricing reform, the UK could create genuine competition and long term national benefit by owning a small share of its renewable generation.
A practical model
Reallocating a small portion of the AI and datacentre investment budget could fund the construction of two large publicly owned offshore wind farms. Electricity from these assets could be sold at a public tariff cheaper than private operators with profits reinvested into expanding renewable capacity, funding public services, lowering taxes, or supporting regional reindustrialisation.
Why this works
Public ownership of even a minority share of generation would:
- Could create downward pressure on prices
- Stabilise bills by reducing dependence on volatile imports
- Generate long term public revenue
- Support UK supply chains and jobs
- Reduce reliance on volatile global markets
Our View
Countries such as Norway, Denmark, and France already benefit from models of public energy ownership. The UK is leaving significant value on the table by relying entirely on private operators in a market where the pricing system prevents consumers from benefiting from cheap generation.
What This Means for the UK
The UK has a genuine choice. By modernising its electricity pricing system and investing in publicly owned renewables, it could lower household bills, increase energy security, reduce reliance on volatile global markets, create long term public revenue, support domestic industry and jobs, and build a more resilient, affordable energy system.
But first, the noise must be cleared. Misinformation thrives when systems are complex and explanations are scarce. Clear, accessible, evidence based information is essential for democratic debate and for making decisions that genuinely benefit the public rather than those with a commercial interest in the status quo.
