Solar’s price drop is astonishing: panels are now 98% cheaper than when I first analyzed them in 2004. Today, building a fence with solar can be cheaper than using wood.

UK currently has 9 TWh of gas stored, compared with 217 TWh in Germany, 122 TWh in France & 162 TWh in Italy. "The UK government dismantled its largest gas storage facility in 2017, a decision taken by then chief secretary to the treasury – Liz Truss." energymonitor.ai/policy/opinion…

THIS IS A HUGE ACHIEVEMENT: The EU now generates more electricity from wind and solar than from fossil fuels. Graph from @NatBullard data @emberclimate

1.5 years ago Germany imported more than 60% of the gas it consumed from Russia. Since late August 2022 it is 0%. The scale of this change is incredible and would have been thought of as impossible in the past. cleanenergywire.org/factsheets/ger…

So many negative media stories about electric vehicles written by people who never owned an electric vehicle. We drove for our family holidays in an EV from the UK via France and Belgium to the German Alps and back. Total trip: >1,800 miles. No problem.

Why laws of thermodynamics don’t apply to Britain is beyond me. Another poor piece on heat pumps by the Telegraph. It’s full of lines from vested interest groups who say heat pumps don’t work in Britain because they want to keep their fossil fuel-based business model alive.

BREAKING: Largest German heating system installer @Thermondo stops installing gas boilers. The last fossil fuel heating system has been sold in February 2024. The company will instead focus on heat pumps, solar and other clean energy technologies.

Social media and newspapers are flooded with myths about heat pumps. Let's take them one by one in this thread.

Heat pumps are magical machines. Instead of combusting fossil fuels to generate heat they transport heat from the air, ground or water into your home. This reduces carbon emissions instantly by about 80% with the current electricity mix. It will be 100% by mid 2030s.

After years and years of media reports that coal is having a comeback in the UK the last coal plant will go offline in just 2 weeks. Coal in the UK is no more. Credit for graph to @KetanJ0
