Fusion does have merits and a large fuel supply from the oceans should we ever get it sustainable, I feel we should at least keep reseaching it.
We are. ITER is probably going to be the first experimental fusion power plant able to produce more energy than is needed to keep the process going.

But yes, practical methods using technology we have now should get the priority, hydroelectric has quite a good yield and a good track record.
Hydroelectricity isn't an option for every country. Geology and stuff, you know? You need rivers and ideally mountain ranges.

I still think windfarms are a dead end, the vastness of the farms and the resources/energy/man hours just are not repaid from what little energy they produce so far.
For most countries windfarms are more viable than hydroelectricity.

Some states have started creating "wind maps" giving detailed information on average wind speeds for every square kilometre of the country. For most areas the percentage of unused land that's viable to use for wind power is around 1-3% of the total land area. That doesn't sound like a lot but it is enough to cover a huge percentage of power production.

And there's still a lot of untapped potential in off-shore wind farms. Wind power will probably not be able to replace fossil fuels completely but it's going to be the backbone of any sustainable renewable energy structure.
