Answer 2

Fossil fuels are the most common form of non-renewable energy resources. Once used up, they cannot be replenished.

So, there is a need for replacement of these energy sources by renewable and eco-friendly energy sources. Solar energy is a renewable source of energy. So, it would be a good alternative to fossil fuels. Similarly, bio-diesel is the biofuel extracted from plants. It is eco-friendly and is renewable.

So, the correct choices will be: solar cells and biodiesel.
