I gather that you are interested in developing a SWOT analysis to determine the best strategies for renewable energy.
The problem with SWOT analysis is that it concludes establishing a SWOT matrix with the advantages and disadvantages of each methodology. From there, the decision-maker needs to make a decision.
If you apply Multi Criteria Decision Making to that matrix you can determine quantitatively which the best strategy is.
Some time ago I wrote something about it. You can find it in my RG profile under the name of 'A new tool for strategic planning'
In my opinion, SWOT Analysis of the Renewable Energy Sources (RES) potential in terms of the current state of country's economy, the country's readiness to change the energy plan, the availability of legal regulations or even the position of the country in the world and possible cooperation with neighbour countries, an can be made on the general concept of RES. But if you want to do the analysis on terms of technical potential and development opportunities in the country, You should separate the sources and make a few analysis for each source. Each source differs from each other, characterized by different properties. The strength of one source can be a threat to another source. And it may also happen that the potential of a one source does not exist in a given country. It will be better to do the analysis for each source. I hope that i helped you a little.
I would suggest that you perform a PESTEL analysis that will allow you to establish priorities among the different renewable energy sources available. Rather than competing with each other these resources should complement each other. In any case a holistic approach is required and technical feasibility should be complemented by economic, political, social and legal aspects.
