Front

How is wind power generated?

Back

Wind power is generated by turbines that are turned by air currents. The movement of the blades of the turbine generates electricity.

Front

Define renewable resources.

Back

Renewable resources are natural resources that can be replenished naturally over time, such as solar energy, wind energy, and biomass.

Front

Define nonrenewable resources.

Back

Nonrenewable resources are natural resources that cannot be replenished in a short period of time, such as fossil fuels (coal, oil, natural gas) and minerals.

Front

What is solar energy?

Back

Solar energy is energy that is harnessed from the sun's rays. It can be converted into electricity or heat for various applications.

Front

What is biomass energy?

Back

Biomass energy is produced from organic materials, such as plant and animal waste. It can be used for heating, electricity generation, and as fuel for vehicles.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, primarily consisting of coal, oil, and natural gas.
