Multiple choice

Which of the following is an example of a renewable energy source that can help reduce carbon emissions and promote biodiversity?

  1. Nuclear power

  2. Coal power

  3. Natural gas power

  4. Solar power
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Solar power is a renewable energy source that generates electricity from the sun's energy. It does not emit greenhouse gases during electricity generation and can contribute to reducing carbon emissions. Additionally, solar farms can provide habitat for wildlife and promote biodiversity.

Multiple choice

Which of the following is an example of a non-renewable energy source that contributes to carbon emissions?

  1. Hydropower

  2. Wind power

  3. Geothermal energy

  4. Fossil fuels
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Fossil fuels, such as coal, oil, and natural gas, are non-renewable energy sources that release carbon dioxide and other greenhouse gases when burned. The use of fossil fuels contributes significantly to carbon emissions and climate change.

Multiple choice

Multiple choice

Which technology is considered a promising option for storing large amounts of renewable energy?

  1. Pumped Hydro Storage

  2. Batteries

  3. Compressed Air Energy Storage

  4. Flywheel Energy Storage
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Pumped Hydro Storage is considered a promising option for storing large amounts of renewable energy, as it involves pumping water uphill when there is excess electricity and releasing it downhill through a turbine to generate electricity when needed.

  1. Wind

  2. Sunlight

  3. Water

  4. Fossil fuels
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Hydropower harnesses the energy of flowing or falling water to generate electricity.

Multiple choice

Which of the following is NOT a type of hydropower plant?

  1. Run-of-the-river

  2. Pumped-storage

  3. Tidal

  4. Geothermal
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Geothermal power plants utilize heat from the Earth's interior, not water, to generate electricity.

Multiple choice

Which type of hydropower plant uses a reservoir to store water and release it during periods of high demand?

  1. Run-of-the-river

  2. Pumped-storage

  3. Tidal

  4. Micro-hydro
Reveal answer Fill a bubble to check yourself
