"One of the key barriers to electrification is the price ratio of electricity to fossil gas prices. In part this price ratio is affected by political choices: the tax rate on electricity used in industry is much higher in most European countries than the tax rate on fossil gas. That creates a disincentive for electrification and an incentive for a continuation of the status quo. There are many options for reforming taxes and levies which I and colleagues looked at here: Source: @ember_energy https://www.sciencedirect.com/science/article/abs/pii/S0301421522005869"

"Rolling back clean energy policies to save European industry will backfire. Whilst it may seem attractive in the short term it is poor industrial policy in the long term. The latest attempts of Germany to once again derail European regulation on the phase-out of the internal combustion engine fall into this category. In my remarks at the European Council this week I emphasised that standing still (or even moving backwards) on climate and clean energy policies is not a path to industrial strength its a risk to Europes competitiveness.

"Key is fixing "clean energy penalty." Currently electricity carries much higher levies than gas making heat pumps harder to adopt. Rebalancing these levies is the most effective way to make clean heating cheaper to run than a gas boilerwithout raising the average total bill"
