Twenty Questions

20 Questions – Energy

Question 1 What is a renewable resource?

The Answer is… Answer: A resource that can be used over again or easily replaced or grown again.

Question 2 Name the 3 fossil fuels.

The Answer is… Coal, oil, and natural gas

Question 3 What is the energy source for hydroelectric power?

The Answer is… water

Question 4 What is a nonrenewable resource?

The Answer is… A resource that cannot be used over again and we will run out of it one day.

Question 5 What do we call the energy from the sun?

The Answer is… Solar energy

Question 6 How does electricity travel to get to your house?

The Answer is… It travels through wires.

Question 7 What do we call the buildings we use to make electricity with fossil fuels?

The Answer is… We usually call them power plants.

Question 8 What kind of natural energy moves a sailboat?

The Answer is… Wind energy.

Question 9 What do we call the factory where crude oil is processed, then made into many different products?

The Answer is… A refinery

Question 10 In a power plant, what is used inside of the generators to make the electricity?

The Answer is… magnets

Question 11 What tall piece of equipment is needed to make electricity using the wind?

The Answer is… windmills

Question 12 True or False – Electricity is a natural resource.

The Answer is… false

Question 13 True or false – Coal is made from plants that died millions of years ago.

The Answer is… true

Question 14 What are “alternative” energy sources?

The Answer is… These are energy sources that are not typically used a lot at this time, such as solar power, wind, wood, and water.

Question 15 What are two types of energy that the sun produces?

The Answer is… Heat and light

Question 16 Put these sentences in order to tell how electricity is produced. A. Steam runs machines that make electricity. B. Hot water turns into steam. C. Power plants burn coal to heat water.

The Answer is… 1. Power plants burn coal to heat water. 2. Hot water turns into steam. 3. Steam runs machines that make electricity.

Question 17 What are some reasons why we need to find other energy sources besides fossil fuels to make electricity?

The Answer is… Fossil fuels are a nonrenewable resource and scientists predict we will run out of them in the next 50 years, so we need to find out how to use alternative energy sources. Burning fossil fuels to make electricity causes a lot of air pollution.

Question 18 You live in a city in the desert where the weather is hot, dry, and sunny about 330 days out of the year. There are very few storms and very few windy days. What type of alternative energy source would you choose to heat the water for your home and to help provide electricity for your home?

The Answer is… Solar energy because of the large amount of sunny days. There is not enough water for hydroelectricity and not enough wind for windmills.

Question 19 What is a source of energy that leaves behind radioactive wates?

The Answer is… Nuclear energy

Question 20 What energy source comes from deep within the earth and is used in some areas to make electricity using heat from melted rock that turns groundwater to steam?

The Answer is… Geothermal energy
