I have said multiple times that we should ban combustion engines in the energy grid. Sadly there isn't a single party that support such action here in Sweden, and the largest supporter of thermal power plants are the green party who see it as essential to enable renewable energy (is written as such in their party platform, website, and argued in public debates).

It would however be a really good first step to make the energy discussion a bit more honest. We don't need combustion engines in order to generate energy.
