Thank you @RoryStewartUK and @campbellclaret for keeping climate and clean energy issues on the agenda. Here at the Carbon Trust, we agree with much of what you said in last Wednesday’s podcast. However, a couple of your claims risk misrepresenting the facts.

It is true that system costs - the total of energy, network, supplier, and policy costs paid by consumers (excluding VAT) – need to be factored in when assessing electricity prices. But these costs are often overstated or wrongly attributed solely to renewables.

In reality, they count for a small share of total bills and reflect growing energy demand and electrification, such as EV charging and heat pumps, which reduce fossil fuel use (and their associated costs) overall.
