Question 1

What is sustainable energy?

Accepted Answer

Sustainable energy comes from sources that won't run out, like the sun, wind, and water. It helps us keep the planet healthy by not polluting the air.

Question 2

How does solar energy work?

Accepted Answer

Solar energy comes from the sun. We use special panels that catch the sunlight and turn it into electricity we can use in our homes.

Question 3

What is wind energy?

Accepted Answer

Wind energy comes from the wind blowing. Big windmills, called turbines, spin when the wind blows, making electricity for us to use.

Question 4

How do plants use the sun’s energy?

Accepted Answer

Plants use sunlight to make food in a process called photosynthesis. This helps them grow, and also gives us oxygen to breathe.

Question 5

What is hydropower?

Accepted Answer

Hydropower uses water to make energy. When water flows downhill, it turns big wheels called turbines, creating electricity.

Question 6

Why is it important to use sustainable energy?

Accepted Answer

Sustainable energy is important because it helps keep the earth clean. It doesn't use up resources that could run out.

Question 7

Can sustainable energy run out?

Accepted Answer

No, sustainable energy doesn't run out. Sources like the sun, wind, and water are always available.

Question 8

What is geothermal energy?

Accepted Answer

Geothermal energy comes from heat inside the Earth. We can use this heat to make electricity or warm our homes.

Question 9

How does the sun make energy?

Accepted Answer

The sun makes energy by burning gases. This energy travels to Earth as sunlight, which we can then use for power.

Question 10

Why don’t we use more sustainable energy?

Accepted Answer

We don’t use more sustainable energy because sometimes it’s expensive or we don’t have the right technology everywhere. But more people are trying to use it every day.

Question 11

What is bioenergy?

Accepted Answer

Bioenergy comes from plants and animals. When we burn these organic materials, they release energy we can use.

Question 12

How does wind make electricity?

Accepted Answer

When the wind blows, it turns the blades of a wind turbine. This movement creates electricity that we can use in our homes.

Question 13

Can we store energy from the sun and wind?

Accepted Answer

Yes, we can store solar and wind energy using batteries. This way, we have power even when the sun isn’t shining, or the wind isn’t blowing.

Question 14

What is renewable energy?

Accepted Answer

Renewable energy is another name for sustainable energy. It means the energy comes from sources that won’t run out.

Question 15

Why is solar energy good for the environment?

Accepted Answer

Solar energy is good for the environment because it doesn’t produce pollution. It also uses a resource, the sun, that won't run out.

Question 16

How do we get energy from waves and tides?

Accepted Answer

We get energy from waves and tides through machines that move with the water. These movements help create electricity.

Question 17

What kind of energy do we get from the sun other than electricity?

Accepted Answer

Besides electricity, we can use the sun’s energy to heat our water and homes. Solar panels can capture sunlight for both heating and power.

Question 18

How are solar panels made?

Accepted Answer

Solar panels are usually made from materials like silicon. These materials help capture sunlight and turn it into electricity.

Question 19

What is a wind turbine?

Accepted Answer

A wind turbine is like a giant pinwheel on a stick. As the wind blows, it turns the blades, making electricity.

Question 20

How can kids help use more sustainable energy?

Accepted Answer

Kids can help by turning off lights when they’re not needed, telling others about the importance of sustainable energy, and using less electricity at home.
