Answer:
Step-by-step explanation:
The term "alternative energy" refers to all nuclear and renewable energy sources as well as energy sources other than fossil fuels (such as coal, petroleum, and diesel).
Nuclear material cannot be regenerated during a human lifetime, so even though it is not as detrimental for the environment as fossil fuels, nuclear energy is not considered a renewable energy source. Utilizing elements with a finite supply, such as uranium and thorium, which cannot be renewed, nuclear energy is created.
Different types of alternative source of energy are:
1. Wind energy
2. Solar energy
3. Nuclear energy
4. Hydrogen gas
5. Tidal energy
