Morocco gets a fair bit of the Sun.Only during daylight hours, which are pretty much the same as the UK. and if you covered Morocco with solar panels, the sensible next step would be to move all your manufacturing industry to Morocco.
Tidal Wave energy has Potential.There have been attempts to harness tidal and wave power for several centuries. Some tidal mills were reasonably successful at grinding corn but AFAIK there are very few suitable locations for tidal generation of electricity and those that aren't commercial ports (not a good idea to erect a dam across Southampton) would require flooding of vast areas of farmland to produce a useful amount of power. Wave power is less predictable than wind and involves enormous quantities of moving machinery being tethered in a hostile environment - again, very little output from a huge number of failed projects over the last 100 years.
Issue being Sea creatures.
Nuclear waste isn't as serious a problem as the quantity of fossil fuel you have to expend to build and fuel up a nuclear power station. Back in the old days, the payback period was about 5 years but it is now more like 20 - 50 years and therefore commercially unattractive.
