Renewable vs Non-renewable Energy

Front

What is renewable energy?

Back

Energy that is generated from natural processes that are continuously replenished, such as sunlight, wind, rain, tides, waves, and geothermal heat.

Front

What is non-renewable energy?

Back

Energy that comes from sources that will run out or will not be replenished in our lifetimes, such as fossil fuels (coal, oil, natural gas) and nuclear energy.

Front

Name three examples of renewable energy sources.

Back

1) Solar energy 2) Wind energy 3) Hydroelectric energy.

Front

What is geothermal energy?

Back

Energy derived from the heat stored beneath the Earth's surface, which can be used for electricity generation and direct heating.

Front

What is biomass energy?

Back

Energy produced from organic materials, such as plant and animal waste, which can be converted into biofuels.

Front

What is the main disadvantage of solar energy?

Back

Solar energy production is dependent on sunlight, which means it is less effective on cloudy days and at night.

Front

How does wind energy work?

Back

Wind energy is generated by converting the kinetic energy of wind into mechanical power using wind turbines.

Front

What is the impact of coal on the environment?

Back

Coal combustion releases significant amounts of carbon dioxide and other pollutants, contributing to air pollution and climate change.

Front

What is the carbon cycle in relation to biomass energy?

Back

The carbon cycle involves the absorption of carbon dioxide by plants during photosynthesis, which is then released back into the atmosphere when biomass is burned.

Front

What is hydroelectric power?

Back

Electricity generated by harnessing the energy of flowing or falling water, typically using dams.
