Nuclear, fine. But where are they on Wind? I'm sure thy have plenty of that on the British Isles.
(Solar probably won't work there though.)

But they're at a potential crossroads in government policy.

It looks like they're cutting back on encouraging solar and changing HOW they encourage some wind power from direct support to penalizing high carbon emissions.

but the implementation just isn't as advanced as offshore wind is. They're still trying to demonstrate a commercially viable design.

The UK is near the front of the wave (pun intended), but offshore wind has much more short/mid-term options.

The Offshore Valuation, which is the source for some of the Scottish figures in the Wikipedia article below, reckons the split of available wave power between Scotland, England and Wales as:

Scotland 15 GW
Wales 1.5 GW
England 1.5 GW

It comments:


Scotland and Ireland have the majority of the west-facing coast.

The 2 power station sites under discussion here are in Wales and England.

About 40 TWh/annum available, compared with 352 TWh consumption in 2009. And if Scotland were to become independent, they'd get about 80% of the available wave power.

but will it work as an alternate power source? for something other than warming water?

Like for example small scale hydro

Scotland's resource potential

The production of renewable energy in Scotland is an issue that has come to the fore in technical, economic, and political terms during the opening years of the 21st century.[1] The natural resource base for renewables is extraordinary by European, and even global standards. In addition to an existing installed capacity[a] of 1.3 Gigawatts (GW) of hydro-electric schemes, Scotland has an estimated potential of 36.5 GW of wind and 7.5 GW of tidal power, 25% of the estimated total capacity for the European Union and up to 14 GW of wave power potential, 10% of EU capacity.[2][3] The renewable electricity generating capacity may be 60 GW or more, considerably greater than the existing capacity from all Scottish fuel sources of 10.3 GW.[2][4] Scotland is on track to exceed its renewable energy target, set in 2007, for 31% of total power generation coming from renewables by 2011, and the 2020 target for the renewable share of total electricity generation has been raised from 50% to 80%.[5]
