Question 1

What is sustainable energy?

Accepted Answer

Sustainable energy is energy that comes from resources that don't run out, like the sun or wind. It’s good for our planet because it doesn't make a lot of pollution.

Question 2

Why is sustainable energy important?

Accepted Answer

It's important because it helps keep our planet clean and healthy. It also means we won't run out of energy in the future.

Question 3

What are some types of sustainable energy?

Accepted Answer

Some types are solar energy from the sun, wind energy from wind, and hydro energy from water. These all help make electricity without pollution.

Question 4

How does solar energy work?

Accepted Answer

Solar energy works by using sunlight to make electricity with special panels called solar panels. It's like a plant using the sun to grow, but instead, we make power.

Question 5

What are wind turbines?

Accepted Answer

Wind turbines are big machines that look like giant fans. They use the wind's power to make electricity.

Question 6

How do wind turbines help the environment?

Accepted Answer

Wind turbines help by making electricity without pollution. They use the wind, which is free and never stops blowing.

Question 7

What is hydro energy?

Accepted Answer

Hydro energy comes from moving water, like rivers. Dams can help collect this energy to make electricity.

Question 8

Can we use ocean waves to make energy?

Accepted Answer

Yes, ocean waves have a lot of energy we can use. There are special machines that can turn wave power into electricity.

Question 9

What makes solar panels special?

Accepted Answer

Solar panels are special because they can turn sunlight directly into electricity. They can be put on rooftops to help power homes.

Question 10

Why don’t we use only sustainable energy?

Accepted Answer

We’re trying to, but it takes time and money to build new power plants. Also, some places don’t get enough sun or wind all year round.

Question 11

How do people store sustainable energy?

Accepted Answer

People use batteries to store energy from the sun or wind. This stored energy can then be used when the sun isn’t shining or the wind isn’t blowing.

Question 12

What are biofuels?

Accepted Answer

Biofuels are made from plants or other natural materials. They can be used instead of gasoline for cars and other machines.

Question 13

How can I help support sustainable energy?

Accepted Answer

You can help by turning off lights when you're not using them. You can also ask your family to use energy-efficient appliances and support renewable energy projects.

Question 14

What is geothermal energy?

Accepted Answer

Geothermal energy comes from heat inside the Earth. We can use it to make electricity and to heat buildings.

Question 15

Why is wind energy clean?

Accepted Answer

Wind energy is clean because it doesn't make pollution. It just uses the wind to spin turbines and make electricity.

Question 16

Is using solar energy expensive?

Accepted Answer

The cost of solar panels has gone down a lot. Once you have them, using solar energy is very cheap because the sun is free.

Question 17

Can cars run on sustainable energy?

Accepted Answer

Yes, some cars use electricity from renewable sources instead of gasoline. There are also cars that use biofuels made from plants.

Question 18

Why is saving energy important?

Accepted Answer

Saving energy helps protect our planet by reducing pollution. It also makes sure we have enough energy for the future.

Question 19

What are renewable energy sources?

Accepted Answer

Renewable energy sources are natural resources like sunlight, wind, and water. They can make energy that won’t run out.

Question 20

What can schools do to help with sustainable energy?

Accepted Answer

Schools can use solar panels or wind turbines to make energy. They can also teach students about saving energy and taking care of our planet.
