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 are the main types of renewable energy?

Back

Solar energy, wind energy, hydroelectric energy, geothermal energy, and biomass.

Front

How does a wind turbine work?

Back

A wind turbine converts the kinetic energy of wind into mechanical energy, which is then converted into electrical energy.

Front

What is the energy transformation in a wind turbine?

Back

Wind --> Mechanical --> Electrical.

Front

What is solar energy?

Back

Energy harnessed from the sun's rays, which can be converted into heat or electricity.

Front

Why is solar energy considered renewable?

Back

Because the sun is expected to shine for another 5 billion years, providing a continuous source of energy.

Front

What is a disadvantage of solar energy?

Back

It only works during the day and is less effective on cloudy days.

Front

What is biomass energy?

Back

Energy produced from organic materials, such as plant and animal waste.

Front

What is geothermal energy?

Back

Energy derived from the heat stored beneath the Earth's surface.

Front

What is the role of potential energy in renewable energy systems?

Back

Potential energy can be converted into kinetic energy, which can then be transformed into electrical energy.
