Renewable and Non Renewable Energy

Front

What is renewable energy?

Back

Energy that is collected from resources that are naturally 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

What is solar energy?

Back

Energy harnessed from the sun using technologies like photovoltaic cells and solar panels.

Front

What is geothermal energy?

Back

Energy derived from the heat stored beneath the Earth's surface, often used to generate electricity or for direct heating.

Front

What is wind energy?

Back

Energy obtained from the movement of air, typically harnessed using wind turbines.

Front

What is hydroelectric energy?

Back

Energy generated by the movement of water, usually from rivers or dams, to turn turbines and produce electricity.

Front

What is biomass energy?

Back

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

Front

What is radioactive waste?

Back

Waste that is produced from nuclear energy processes, which can remain hazardous for thousands of years.

Front

What is a disadvantage of fossil fuels?

Back

They cause pollution when burned, contributing to air quality issues and climate change.

Front

What is the main advantage of renewable energy?

Back

It is sustainable and has a lower environmental impact compared to non-renewable energy sources.
