Multiple choice

Which of the following is a renewable energy source commonly used in energy-efficient buildings?

  1. Fossil fuels

  2. Nuclear energy

  3. Solar energy

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

Solar energy is a renewable energy source that is commonly used in energy-efficient buildings through the installation of solar panels.

Multiple choice

Which of the following is a renewable energy source?

  1. Coal

  2. Natural gas

  3. Solar power

  4. Nuclear power
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Solar power is a renewable energy source that harnesses the energy from the sun to generate electricity. Unlike fossil fuels, which are finite and contribute to greenhouse gas emissions, solar power is a clean and sustainable alternative.

Multiple choice

Which of the following is a non-renewable energy source?

  1. Wind power

  2. Hydropower

  3. Fossil fuels

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

Fossil fuels, such as coal, oil, and natural gas, are non-renewable energy sources formed from the remains of ancient plants and animals. These fuels are finite and their combustion releases greenhouse gases, contributing to climate change.

  1. Run-of-the-river

  2. Impoundment

  3. Pumped-storage

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

Run-of-the-river plants use the existing flow of a river to generate electricity without creating a reservoir.

Multiple choice

What is the term used for the artificial lake created by a dam in a hydropower system?

  1. Reservoir

  2. Forebay

  3. Tailrace

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

A reservoir is an artificial lake created by a dam to store water for various purposes, including hydropower generation.

Multiple choice

Which component of a hydropower plant converts the kinetic energy of water into mechanical energy?

  1. Turbine

  2. Generator

  3. Transformer

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

The turbine in a hydropower plant converts the kinetic energy of flowing water into mechanical energy, which is then used to drive the generator.

Multiple choice

Which type of hydropower plant uses a reversible turbine that can both generate and pump water?

  1. Run-of-the-river

  2. Impoundment

  3. Pumped-storage

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

Pumped-storage hydropower plants use reversible turbines to pump water uphill during periods of low electricity demand and generate electricity by releasing the water downhill during periods of high demand.

Multiple choice
