A country has a long coastline with a large tidal range and many hours of sunshine in the summer. The country has no fossil fuel reserves of its own. At present it imports coal and burns the coal to generate all of its electricity.
The government must choose between building a tidal scheme and building a large number of solar farms.
Compare the use of a tidal scheme with the use of solar farms for generating electricity in this country. In your answer you should refer to reliability, to the effect on the environment, and to how well each one matches the times when electricity is needed.
