This sounds nice and unbiased on paper, but often this means that rather than expanding alternatives, the poor are simply made to go without and then they will scream at politicians for relief until they get it and you are right back at square one.
As a fellow Swede you will know how the price of gasoline has become a hot topic and how politicians campaigned on bringing the price down again by reversing climate policies.
Personally I think the solution is to make a commie-style 5 year plan and then work backwards to what kind of incentives would be needed for that plan, probably involving industry leaders in that discussion. Then you can make sure that the incentives are technology neutral. This ensures that if nothing better comes along the "free" market will execute 5 year plan but they do have the option of gambling on alternatives if they so choose or if some wonder technology emerges out of a secret lab.
