The UK’s gasoline imports could be 13% decrease if successive Conservative-led governments had not “minimize the inexperienced crap” over the previous decade, Carbon Transient evaluation reveals.
The findings come as the federal government’s North Sea Transition Authority broadcasts a new licensing spherical for North Sea oil and gasoline, with the acknowledged goal of accelerating UK power safety. The evaluation additionally follows information that the UK is vulnerable to blackouts if imports of gasoline and electrical energy are restricted.
Carbon Transient’s evaluation reveals that UK gasoline imports would have been minimize by 65 terawatt hours (TWh) if authorities help for power effectivity and renewables had continued, as an alternative of being rolled again after then-prime minister David Cameron instructed ministers in 2013 to “minimize the inexperienced crap”.
This saving would have been practically twice as giant because the 34TWh imported from Russia final yr. It might have been enough to chop the UK’s web gasoline imports by 13% total, considerably boosting power safety. The saving would have averted shopping for 65TWh of gasoline at a price of round £5bn.
Many of the financial savings would have been from extra onshore wind and photo voltaic capability, which might have minimize UK gasoline demand for electrical energy by 20%. Furthermore, the evaluation reveals that gasoline demand for electrical energy era would have been twice as excessive, if the UK had no renewable power sources.
‘Slicing the inexperienced crap’
From 2013 onwards, successive Conservative-led governments minimize help for house power effectivity enhancements, scrapped a requirement for brand spanking new properties to be “zero carbon”, ended subsidies for onshore wind and photo voltaic, and successfully banned onshore wind in England.
This brought about a precipitous decline within the fee of house power effectivity enhancements, led to thousands and thousands of inefficient new properties being constructed and dramatically diminished the quantity of onshore wind and photo voltaic capability being constructed every year, as proven in Carbon Transient’s January 2022 evaluation.
The brand new Carbon Transient evaluation aggregates these local weather coverage rollbacks by way of the gasoline demand they might have averted, if the measures had remained in place.
In complete, UK gasoline demand would have been 65TWh decrease if it had insulated extra properties (11TWh), constructed new properties to zero-carbon requirements (2TWh) and continued so as to add onshore wind (31TWh) and photo voltaic (20TWh) at historic charges.
This saving from not “reducing the inexperienced crap” is proven by the purple bars within the chart beneath, relative to UK gasoline demand in 2021 (gray) and relative to web UK gasoline imports in the identical yr (gentle blue). The chart additionally reveals direct imports from Russia in 2021 in darkish blue.

Discount in gasoline demand if governments had not “minimize the inexperienced crap” (purple). Supply: Carbon Transient evaluation. Chart by Carbon Transient utilizing Highcharts.
The 65TWh of financial savings are practically twice the 34TWh imported as liquified pure gasoline (LNG) by ship from Russia final yr and would have enabled the UK to chop its gasoline imports by 13% total.
On the £77 per megawatt hour common value of gasoline throughout 2022 thus far, this 65TWh would have amounted to a saving price £5bn in averted gasoline prices.
Electrical energy provide
The vast majority of the financial savings would have come from persevering with to construct onshore wind and photo voltaic at historic charges, as an alternative of seeing their progress collapse attributable to local weather coverage rollbacks.
Carbon Transient’s evaluation assumes onshore wind would have grown on the similar fee as in 2017, when 1.8 gigawatts (GW) was constructed, that means an additional 5.4GW being constructed by the top of 2021. It assumes an additional 10GW of photo voltaic capability would have been added throughout 2016-2021. That is based mostly, conservatively, on including capability at 2016 ranges, properly beneath the height seen in 2017.
In complete, this 15GW of additional renewable capability would have generated some 25TWh of electrical energy per yr on common. Producing this electrical energy at common UK gas-fired energy stations would require 51TWh of gasoline, as a result of half the power within the gas is misplaced as waste warmth.
This saving from not “reducing the inexperienced crap” is proven by the purple bar within the chart beneath – a 20% minimize relative to precise UK gasoline demand for electrical energy era in 2021 (gray).

Enhance in gasoline demand if the UK didn’t have any renewable power sources (blue). Supply: Carbon Transient evaluation. Chart by Carbon Transient utilizing Highcharts.
This additional onshore wind and photo voltaic capability would have boosted UK safety of provide, rising the “derated margin” between anticipated peak demand and accessible provide to eight.1%, up from 6.3% within the “base case” lately revealed by the Nationwide Grid Electrical energy System Operator (NGESO).
This derated margin, which takes under consideration the anticipated availability of several types of energy station, would have been 4.8GW, as an alternative of three.7GW within the NGESO base case.
As well as, the chart reveals how far more gasoline would have been wanted if the UK had not bought 40% of its electrical energy from renewable sources in 2021.
The UK would have wanted to double the 254TWh of gasoline used to generate electrical energy final yr, if it had not had any provides from wind, photo voltaic, hydro and biomass energy.
This may have elevated UK gasoline demand in 2021 by 29% at a price of round £10bn.
