I just insist on nuclear. Reliable output all year round, vastly more efficient in land usage than other forms, completely safe and with practically zero environmental impact. The technology has advanced a fair bit since the 60's. Thorium fluoride reactors have no risk of catastrophic failure, no nuclear proliferation, and once we start working with fusion we will have a few thousand years of practically free energy for the whole planet.

Putting structures in the sea, or windmill farms covering vast fields really makes me worry about the environmental damage that does. The expense and waste down the line are also annoying.
