Which argument(s) for the increasing use of solar energy is/are valid? i. solar cells are becoming cheaper and increasingly more efficient ii. the cost of generating electricity from fossil fuels is increasing iii. limited and uncertain supply and the increasing requirements for pollution control are raising the cost of using fossil fuels

The correct one is (III)

Explanation: Limited and uncertain supply and the increasing requirements for pollution control are raising the cost of using fossil fuels.

This is because fossil fuels emit green house gases that are causing global warming. As a result more awareness have been drawn towards the harmful use of fossil fuels, and international bodies are starting to form regulations on the use of fossil fuels. These above reasons has made fossil fuels though abundant, very expensive to use.

This make the usage of greener sources of energy like solar energy desirable. The only challenge solar is facing is on the area of efficiency, but scientists are constantly researching to make it more efficient.
