Front

What is hydropower?

Back

Hydropower is energy derived from the movement of water, typically harnessed through dams and turbines to generate electricity.

Front

What does it mean to pump water in hydropower systems?

Back

Pumping water in hydropower systems refers to the process of moving water back into a reservoir to store energy for later use, especially during peak demand.

Front

What is the minimum average annual wind speed for efficient wind turbine sites?

Back

14.5 mph or 6.5 m/s is the minimum average annual wind speed necessary for wind turbine sites to be considered efficient.

Front

Which renewable energy source is most effective at reducing carbon emissions?

Back

Solar energy is considered the most effective renewable energy source for reducing carbon emissions.

Front

What are the types of solar power?

Back

The types of solar power include Active, Passive, Photovoltaic, and Thermal.

Front

What is the availability of solar energy dependent on?

Back

The availability of solar energy depends on the time of day, as it is only generated when sunlight is present.

Front

What is the principle behind geothermal energy?

Back

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

Front

What is biomass energy?

Back

Biomass energy is produced from organic materials, such as plant and animal waste, which can be converted into fuel.

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 role of reservoirs in hydropower?

Back

Reservoirs in hydropower systems store water that can be released to generate electricity when needed.
