Thank you, Mr Deputy Speaker, for the opportunity to speak in this debate.
If we did not already know that decarbonising our energy supply is one of the most urgent challenges facing not just this country but the whole world, the ongoing discussions in Glasgow at the COP26 summit have certainly informed us. There is now worldwide consensus on the need to phase out the use of coal and other fossil fuels in energy production, transport, heating and industry, and it is encouraging to hear some of the commitments made by delegates towards that goal. We have quite a good story to tell already on that in this country. In the UK, energy production accounts for approximately 15% of all carbon emissions. One significant challenge we face is how to replace the role of coal and fossil fuels in energy production with carbon-free alternatives, but we have already made great progress in decarbonising our energy supply. Carbon dioxide emissions from power stations were 75% lower in 2020 than in 1990, and this change has come about largely from the introduction of new energy sources, particularly renewables, such as wind and solar. The use of coal in our power supply fell sharply from the mid-2010s onwards, after which the use of renewables expanded rapidly. Wind power is now the cheapest form of electricity generation, and it was Government policy that made the substantial difference to this change, notably the decision of the then Secretary of State for Energy and Climate Change to introduce contracts for difference to incentivise private sector investment into the renewables sector. That Secretary of State was my right hon. Friend the Member for Kingston and Surbiton (Ed Davey), whom, I gather, went on to more exalted roles.
The legislation has strong precedents. Unlocking the barriers to private sector investment into carbon-free alternatives in our energy market has catalysed the changes we need to see. We need to go further to make sure that we can completely decarbonise our energy sector, supporting renewables and household and community energy.
