Westinghouse has a modular design PWR reactor :AP-600 and AP-1000 (600MW & 1000MW) which has failsafe mechanisms that work on natures laws of gravity- thus it has less moving parts and it takes only 5 years to build. The south africans and the chinese are working on pebble bed reactor designs that are small and modular and could be build at even less cost. Some of these pebble bed designs are so small they fit in the basement of a building and could provide enought ""juice" to heat a whole city through winter.These reactor designs are cheaper than French, Finnish and Swedish designs and could be funded with both EU structual funds and bond issues. There would be enough capacity that Estonia could export the excess electricty to further offset the costs. Such a plant could also produce hydrogen fuel at a sensible cost, thus making Estonia an innovative green nation. This know-how could be sold all over the world. This is simple in engineering terms (I have a Bachelors Degree in Nuclear Engineering & operation reactor experience from Kansas State University) but a near impossibility in terms of political will. I can offer myself as the first special interest lobbyist in Estonia to advocate for nuclear power and educate the general population how new technology reactors are inheritantly safe and could never do a Chernobyl. This is Estonia's ticket to energy independence and it should be made a "manhattan project" priority by government and business leadership in all sectors as they stand to benefit long term.

I still do not know how to store energy, from windmills for example.
Does anybody know this?

Government Bond, great summary! I think Estonia should do b, but taking the mentality of Estonia today into account unfortunately it will most certainly be d.
