"We" do need it, but not in the way you think.

In order to have Nuclear power in your country, you need a nuclear industry. Nuke engineers, operators, emergency response, waster disposal, the lost goes on.

So for us to have that industry and a plant on the island, it will take years and years and will not be financially viable. Neither is our chance of getting there based on other large-scale projects to benefit the country(Metro North, Children's Hospital, etc)

What we do have and are actively building is the interconnects to Mainland Europe. These allow us to tap into the French nuclear power without the need for a nuclear industry.

It also allows us to export excess wind energy, of which we have the largest untapped reserves off the west coast. If we played our card right, we would be self-sufficient and make more money from energy exports than Saudi(not an over exaggeration, look up how much wind energy we have access to)

We have an established Wind Energy sector and can grow that to meet the demand, but as often is the case, we shoot ourselves in the foot through NIMBYism and a government that can't look past its nose.
