Explanation:

In solar thermal generators. they depends solely on sun's energy for its energy generation and distribution. The energy generation made use of solar cells which are cells joined together in series which helps in trapping the sun's energy and converting them into electric charges for its onward transmission to the circuit and battery leading to electricity.

On the other-hand, over dependence on fossil fuel causes environmental issues like global warming due to gas flaring etc.
