Pauline Latham – 2022 Speech on Burning Trees for Energy Generation
The speech made by Pauline Latham, the Conservative MP for Mid Derbyshire, in Westminster Hall, the House of Commons, on 6 December 2022.
It is a pleasure to serve under your chairmanship, Mr Gray. I congratulate my hon. Friend the Member for North Devon (Selaine Saxby) on securing this important debate, and all right hon. and hon. Members who have contributed so far. This is a crucial issue, and the timing of the debate could not be better. The Government intend to publish their biomass strategy shortly, and I am glad we have the opportunity to make our views known to the Minister in the hope of influencing the soon-to-be-published strategy.
In February, I published an article highlighting the problems with biomass, and I will set out the two key points from it. The first reason why we should avoid continued reliance on biomass relates to the financial and economic sustainability of biomass energy production, which Members have talked about. The current energy crisis, coupled with the climate crisis, means that we need to transition to renewable energy as quickly and cheaply as possible. In the context of rising bills, every pound of taxpayers’ money that goes into subsidising energy production must have the maximum effect. When wind and solar power technology were still prohibitively expensive, we were led to believe that biomass was the answer to all our problems—a carbon-neutral solution that was comparatively cheap. However, things have turned out rather differently: currently, we are subsiding biomass energy prices to the tune of £1 billion a year.
Offshore wind power, on the other hand, has been decreasing in price substantially. Since the 2014 contracts for difference auction, the strike price of offshore wind has come down from £155 per MWh to just £37.35 per MWh in 2022. Biomass, meanwhile, remains at over £90 per MWh, and there is no expectation that its price will fall in the years to come; indeed, adding carbon capture and storage to biomass technology will drive the price even higher—never mind the transportation costs. It was not the wrong economic decision in 2014 to favour biomass and to subsidise that technology—it was the best-value renewable option then. However, it would certainly be the wrong decision in 2022, because of the extraordinary improvements that there have been in wind power technology. From a financial perspective, the Government cannot justify subsidising biomass with public money when that money could instead be used to increase the generation of offshore wind.
The second reason why we should not support and encourage biomass over other renewable energy sources is that its renewable credentials are really very weak. Burning wood pellets actually releases 18% more CO2 than burning coal, according to the Intergovernmental Panel on Climate Change; we only consider it a renewable source because new, replacement trees can absorb that carbon dioxide. However, as has been said, it would take nearly 190 years for the CO2 released by burning trees to be absorbed. At the end of this month, we will have only 27 years left to meet the Government’s target of net zero by 2050, so creating CO2 emissions that will not be absorbed for two centuries should not count as progress towards net zero.
In theory, biomass is not ideal, although it was acceptable when it seemed cheaper than other renewable sources; in practice, it is far worse. The BBC’s “Panorama” exposed some of the practices at Drax’s biomass generation facilities, including that none of the wood burned is from the UK and that that one biomass power station burns the equivalent of half the New Forest every year—27 million trees. The use of farmland and natural habitats for biomass crops takes away from our efforts to restore nature and halt the decline of species by 2030. The World Wildlife Fund estimates that if bioenergy were produced domestically, biomass production would require 30% of UK agricultural land. We would have to replace the food that that land produces with more from abroad, at a time when we already have a problem with our food security.
It is clear that there are serious problems, as well as financial concerns, with biomass as an environmentally sustainable power source. There is no doubt that biomass was useful and important as part of the energy mix in the 2010s, but it is completely wrong now. I hope the Minister will confirm that the Government’s biomass strategy limits the role of biomass to a replacement for fossil fuels, not a competitor for renewable energy transition funding. That means reducing or stopping the subsidies for biomass and putting that money into continuing to support domestic forms of renewable energy production such as offshore wind.
