  1. Solar energy

  2. Wind energy

  3. Hydropower

  4. Natural gas
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Renewable energy sources are those that can be replenished naturally and do not contribute to greenhouse gas emissions. Solar energy is an example of a renewable energy source.

Multiple choice

What is the primary energy source for tropical cyclones?

  1. Solar radiation

  2. Wind energy

  3. Ocean heat

  4. Lightning strikes
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Tropical cyclones derive their energy from the warm waters of the ocean, which provide the latent heat necessary for the formation and intensification of the storm.

Multiple choice

Which of the following is NOT a renewable energy source?

  1. Solar

  2. Wind

  3. Hydropower

  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 because they are formed from the remains of ancient plants and animals over millions of years. Renewable energy sources, on the other hand, are replenished naturally on a human timescale.

Multiple choice

What is the primary source of biomass for bioenergy production?

  1. Wood and wood waste

  2. Agricultural crops and residues

  3. Animal manure

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Biomass for bioenergy production can be derived from a variety of sources, including wood and wood waste, agricultural crops and residues, animal manure, and even algae. The specific source used depends on the availability and cost of the biomass in a particular region.

Multiple choice

Which of the following is a common technology for converting biomass into electricity?

  1. Gasification

  2. Pyrolysis

  3. Anaerobic digestion

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Gasification, pyrolysis, and anaerobic digestion are all technologies that can be used to convert biomass into electricity. Gasification involves heating biomass in the presence of oxygen to produce a combustible gas, which is then burned to generate electricity. Pyrolysis involves heating biomass in the absence of oxygen to produce a bio-oil, which can be used as a fuel or further processed to produce other products. Anaerobic digestion involves the breakdown of organic matter by microorganisms in the absence of oxygen, producing biogas (primarily methane), which can be burned to generate electricity.

Multiple choice

Which of the following is a common type of wind turbine?

  1. Horizontal-axis wind turbine

  2. Vertical-axis wind turbine

  3. Both of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Horizontal-axis wind turbines and vertical-axis wind turbines are the two main types of wind turbines. Horizontal-axis wind turbines are the most common type, and they consist of a rotor with blades that rotate around a horizontal axis. Vertical-axis wind turbines have a rotor with blades that rotate around a vertical axis. Vertical-axis wind turbines are less common than horizontal-axis wind turbines, but they have some advantages, such as being able to operate in lower wind speeds.
