Answer 1

There are two types of Sources: Renewable Sources and Non-renewable Sources.

Key Points

(Energy Source)	(Environmental Impacts)
Wind Energy	Wind energy is the process of using the wind to produce mechanical or electrical energy. Wind turbines affect birds and bats, including several rare species.
Thermal Energy	The thermal energy that results from the number of molecular vibrations increases with temperature. Thermal energy sources are fossil fuels like natural gas, coal, and oil. It is the largest source of Green House gases from the burning of fossil fuels.
Hydroelectric Energy	Hydroelectric Energy is generated after creating a dam on the natural flow of a river or body of water. Dam water level fluctuations may also have an effect on riparian vegetation.
Photovoltaic energy	Photovoltaic solar energy harnesses solar radiation to generate electricity. It is based on a phenomenon known as the photoelectric effect. It produces electronic waste which contains lead, cadmium, and other toxic chemicals.

Therefore, (A) - (III), (B) - (I), (C) - (II), (D) - (IV) is correct matching.
