Many European countries subside changes for their own reasons, some because they do believe in climate change, but hey - it's just economy for them.
If I can change an import from another country to a domestic source (electricity in my country), and increase the output so we even can export the product to countries that put nuclear out of use (read Germany),
The result is that country will have more export and less import.
A change from oil based heating/transport to me was an easy choice, it took 3-4 years to get even on my investments in energy changes.
Of course, when enough have done their changes, they will increase tax on electricity and Ethanol so state income will remain the same, you just have to board the train early to benefit from it.
