Renewable vitality is usually pitched as cheaper to provide than fossil gasoline vitality. To quantify whether or not that is true, we have now been learning the monetary influence of increasing wind vitality within the UK. Our outcomes are shocking.
From 2010 to 2023, wind energy delivered a good thing about £147.5 billion — £14.2 billion from decrease electrical energy costs and £133.3 billion from lowered pure fuel costs. If we offset the £43.2 billion in wind vitality subsidies, UK customers saved £104.3 billion in contrast with what their vitality payments would have been with out funding in wind era.
UK wind vitality manufacturing has remodeled over the previous 15 years. In 2010, greater than 75% of electrical energy was generated from fossil fuels. By 2025, coal has ceased and wind is the most important supply of energy at 30% – greater than pure fuel at 26%.
This large growth of UK offshore wind is partly on account of UK authorities subsidies. The Contracts for Distinction scheme gives a assured worth for electrical energy generated, so when the worth drops under this stage, electrical energy producers nonetheless get the identical amount of cash.
The growth can be partly on account of how nicely UK situations swimsuit offshore wind. The North Sea gives each ample winds and comparatively shallow waters that make set up extra accessible.

How a extra versatile vitality grid can cope higher with swings in Britain’s climate
The constructive contribution of wind energy to decreasing the UK’s carbon footprint is well-known. In line with Christopher Vogel, a professor of engineering who specialises in offshore renewables on the College of Oxford, wind generators within the UK recoup the vitality used of their manufacture, transport and set up inside 12-to-24 months, and so they can generate electrical energy for 20-to-25 years. The monetary advantages of wind energy have largely been missed although, till now.
Our examine explores the economics of wind within the vitality system. We take a long-term modelling strategy and take into account what would occur if the UK had continued to put money into fuel as an alternative of wind era. On this situation, the result’s a big elevated demand for fuel and subsequently greater costs. Not like earlier short-term modelling research, this strategy highlights the longer-term monetary profit that wind has delivered to the UK shopper.

Central to this examine is the idea that with out the extra wind vitality, the UK would have wanted new fuel capability. This various situation of fuel quite than wind era in Europe implies an annual, ongoing improve in UK demand for fuel bigger than the discount in Russian pipeline fuel that prompted the vitality disaster of 2022.
Given the numerous improve within the price of pure fuel, we calculate the UK would have paid an additional £133.3 billion for vitality between 2010 and 2023.
There was additionally a direct monetary profit from wind era in decrease electrical energy costs – about £14.2 billion. This mixed saving is much bigger than the overall wind subsidies in that interval of £43.2 billion, amounting to a internet profit to UK customers of £104.3 billion.
Wind energy is a public good
Wind mills scale back market costs, creating worth for others whereas limiting their very own profitability. That is the mirror picture of industries with destructive environmental penalties, comparable to tobacco and sugar, the place the trade doesn’t pay for the elevated related healthcare prices.
Which means the profitability of wind mills is a flawed measure of the monetary worth of the sector to the UK. The funds by way of the UK authorities should not subsidies creating an trade with extra earnings, or one making a monetary drain. They’re investments facilitating cheaper vitality for UK customers.
Wind energy must be considered as a public good — like roads or colleges — the place authorities help results in nationwide positive aspects. The present funding mannequin makes electrical energy customers bear the associated fee whereas fuel customers profit. This big subsidy to fuel customers raises equity considerations.
Wind funding has considerably lowered fossil gasoline costs, underscoring the necessity for a strategic, equitable vitality coverage that aligns with long-term nationwide pursuits. Reframing UK authorities help as a high-return nationwide funding quite than a subsidy can be extra correct and efficient.
Sustainability, safety and affordability don’t should be in battle. Wind vitality is crucial for vitality safety and local weather targets – plus it makes over £100 billion of economic sense.
