Nonrenewable & Renewable Energy Review

Front

What is a nonrenewable energy source?

Back

A nonrenewable energy source is a type of energy that cannot be replenished in a short period of time, such as fossil fuels (coal, oil, natural gas) and nuclear energy.

What is a renewable energy source?

Back

A renewable energy source is an energy source that can be replenished naturally in a short period of time, such as solar, wind, hydroelectric, and geothermal energy.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, which are used as energy sources, including coal, oil, and natural gas.

Front

What is tar sands oil?

Back

Tar sands oil is a type of unconventional fossil fuel found in sand deposits, where bitumen is extracted and processed to produce crude oil.

Front

What does 'intermittent' mean in the context of energy sources?

Back

'Intermittent' refers to energy sources that do not provide a constant supply of electricity and generate power at irregular intervals, such as solar and wind energy.

Front

What is geothermal energy?

Back

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

Front

What is required for geothermal power plants to be effective?

Back

Geothermal power plants need to be located in areas where magma is close to the Earth's surface to access the heat necessary for energy production.

Front

What is a hydroelectric dam?

Back

A hydroelectric dam is a structure that uses the flow of water to generate electricity, typically by harnessing the energy of flowing or falling water.

Front

What is pumped storage in hydroelectric systems?

Back

Pumped storage is a method used in hydroelectric systems to store energy by pumping water to a higher elevation during low demand and releasing it to generate electricity during high demand.

Front

What is solar energy?

Back

Solar energy is energy harnessed from the sun's rays, which can be converted into electricity or heat using solar panels and other technologies.
