Power Investment Options - Alternatives to Carbon

I would like more policy option alternatives for the state to generate electricity.
I think there should be more alternatives besides CO2 restriction or reduction.

Viable alternatives that would allow a credible energy mix at a cost should be available.

Investment into a H2-Hydrogen Economy - or Nuclear Economy (80% Electricity Generated in France is Nuclear) - Dam Creation - or perhaps even the option to buy electricity from foreigns neighbours should be available and reduce CO2 generation.
