Solar energy is a renewable energy source because it is derived from the sun, which is a constantly replenished source of energy.

Coal is a non-renewable energy source because it is formed from the remains of plants that lived millions of years ago. Once coal is burned, it cannot be replaced.

Renewable energy sources are sustainable because they are derived from sources that are constantly replenished, such as the sun, wind, and water. They do not produce greenhouse gases, which contribute to climate change.

Renewable energy sources can be intermittent and unpredictable, meaning that they may not be available when they are needed. For example, solar energy is not available at night, and wind energy is not available when the wind is not blowing.

Hydroelectric power is a renewable energy source that is used to generate electricity by harnessing the power of moving water.

Coal is a non-renewable energy source that is used to generate electricity by burning it in a power plant.

Geothermal energy is a renewable energy source that is used to heat homes and businesses by harnessing the heat from the Earth's core.

Natural gas is a non-renewable energy source that is used to heat homes and businesses by burning it in a furnace or boiler.

Electric energy is a renewable energy source that is used to power vehicles by storing it in a battery and using it to drive an electric motor.

Gasoline is a non-renewable energy source that is used to power vehicles by burning it in an internal combustion engine.

Wind energy is a renewable energy source that is used to generate electricity by harnessing the power of the wind.

Nuclear energy is a non-renewable energy source that is used to generate electricity by splitting atoms.

Solar energy is a renewable energy source that is used to heat homes and businesses by harnessing the power of the sun.

Natural gas is a non-renewable energy source that is used to heat homes and businesses by burning it in a furnace or boiler.

Electric energy is a renewable energy source that is used to power vehicles by storing it in a battery and using it to drive an electric motor.
