Slightly? Have you looked at the energy prizes lately? I think the approach, pain now, sustainanble energy and independency of fosssils later, is highly risky. What if the alternatives are not ready for the winter?
The alternative is continued financial support of Russia, which feeds their unacceptable invasion of Ukraine, and the murders of civilians and countless war-crimes.
Increased energy-prices is a price I am willing to pay. If you prefer supporting Putin to save some money, that is your opinion, which you are free to have.
