Question

Which one among the following is NOT a source of renewable energy?
1. Hydroelectricity
2. Solar energy
3. Fuel cell
4. Wind energy

Answer 1

Correct Answer - Option 3 : Fuel cell

The correct answer is the Fuel cell.

• The fuel cell is not a source of renewable energy.
• Non-renewable energy comes from sources that will run out or will not be replenished in our lifetimes or even in many, many lifetimes. 
• Examples of non-renewable energy -  fossil fuels - coal, petroleum, and natural gas, etc.
• Renewable energy referred to as clean energy, comes from natural sources or processes that are constantly replenished.
• Some examples of renewable energy - Solar energy, Wind energy, Ocean and biomass, etc.

• Hydroelectricity: Hydroelectricity is electricity made by generators that are turned by the movement of water.
• It is usually made with dams that partly block a river to make a reservoir of water. Water is released, and the pressure of the dam forces the water down pipes that lead to a turbine.
• Solar Energy: Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants, and artificial photosynthesis.
• Wind Energy: Wind power or wind energy is the use of wind to provide mechanical power through wind turbines to turn electric generators for electrical power. Wind power is a popular sustainable, renewable source of power that has a much smaller impact on the environment compared to burning fossil fuels.
