Renewable Energy - Part 1

Front

What is renewable energy?

Back

Renewable energy is energy that can be replaced as quickly as it is used, such as solar, wind, and hydroelectric energy.

Front

What is a disadvantage of using hydroelectric power?

Back

It is associated with the release of methane into the air.

Front

How does renewable energy compare to fossil fuels in terms of pollution?

Back

Most renewable energy resources produce less pollution than fossil fuels.

Front

What do photovoltaic cells do?

Back

Photovoltaic cells capture the photons of sunlight to provide enough energy for electrons to move, thereby producing electricity.

Front

Why is solar energy considered renewable?

Back

The sun's energy would not run out for billions of years.

Front

What is an example of a renewable energy source?

Back

Solar energy, wind energy, and hydroelectric energy are examples of renewable energy sources.

Front

What is the main advantage of renewable energy?

Back

Renewable energy sources are sustainable and can help reduce pollution and dependence on fossil fuels.

Front

What is the role of a turbine in renewable energy generation?

Back

A turbine converts kinetic energy from wind or water into mechanical energy, which is then converted into electricity.

Front

What is biomass energy?

Back

Biomass energy is produced from organic materials, such as plant and animal waste, which can be used to generate electricity.

Front

What is geothermal energy?

Back

Geothermal energy is heat energy generated and stored in the Earth, which can be used for heating and electricity generation.
