Replacing one dependency with another is not a sustainable approach to energy in Europe.
The only way out of this is to move full speed ahead on electrification, energy efficiency and renewable energy.

Anyone complaining about solar panels taking up space needed for growing food needs to look hard at this chart. Solar panels are *massively* more efficient than biofuels.
The world dedicates a Poland-sized area of land to producing liquid biofuels such as bioethanol & biodiesel. Is there a more efficient way to generate energy?
Putting solar panels on the land used for biofuels, e.g., would produce enough electricity for all cars and trucks worldwide to go electric.

One thing 2025 made clear: Durable progress on climate in the US will require structural reform to our corrupted political systems. Otherwise, steps forward will always be vulnerable to the bloody clawbacks we saw this year. A political strategy that doesn't center system reform is not "pragmatic."

New study estimates that German households who remain on natural gas in 2045 could be stuck paying 10x what they pay today for gas pipeline maintenance. As other households electrify, gas utilities will spread the same maintenance costs over fewer remaining customers, raising prices dramatically.

Drivetrain of an electric vehicle has about 20 parts. The drivetrain of an internal combustion engine has over 2,000. Even the most expensive internal combustion engine can't put out the torque of an inexpensive EV. The change will happen regardless of what the petrol people want. And fast.
