Question 1

What is renewable energy?

Accepted Answer

Renewable energy comes from natural sources that never run out, like the sun, wind, water, and plants. It's like using a magical backpack that keeps refilling itself.

Question 2

How does solar energy work?

Accepted Answer

Solar energy comes from sunlight. Solar panels catch sunlight and turn it into electricity, a bit like how plants take sunlight and turn it into food.

Question 3

What is wind energy?

Accepted Answer

Wind energy uses wind to create power. When the wind blows, it turns big blades on windmills, and that movement makes electricity.

Question 4

How do windmills work?

Accepted Answer

Windmills have big blades that spin when the wind blows. This spinning action turns on a generator inside the windmill to make electricity.

Question 5

What is water energy or hydropower?

Accepted Answer

Water energy, or hydropower, uses water to make electricity. Rivers or waterfalls turn things like water wheels, which create power for us to use.

Question 6

How does a water dam make energy?

Accepted Answer

A water dam holds back a lot of water. When the water is released, it flows down and spins turbines, turning them to create electricity.

Question 7

What is biomass energy?

Accepted Answer

Biomass energy comes from plants and waste. It's like using old leaves, wood, and natural things to make fuel, just like how a compost pile breaks down to feed plants.

Question 8

How do plants make energy?

Accepted Answer

Plants turn sunlight into energy by a process called photosynthesis, just like how solar panels make electricity. This energy can be used as a fuel after the plants are burned.

Question 9

Why is renewable energy important?

Accepted Answer

Renewable energy is important because it doesn't run out and it doesn't pollute the air. This helps protect nature and animals from harm.

Question 10

How does renewable energy help the Earth?

Accepted Answer

Renewable energy helps the Earth by keeping the air and water clean. It also reduces the bad stuff that makes the Earth's climate change.

Question 11

Is renewable energy expensive?

Accepted Answer

Although it can be costly at the start to build things like solar panels or windmills, renewable energy usually becomes cheap because the 'fuel'—like sunlight or wind—is free.

Question 12

What is geothermal energy?

Accepted Answer

Geothermal energy comes from the heat inside the Earth. Deep holes are drilled to bring this heat up to the surface to make electricity.

Question 13

How do geothermal plants work?

Accepted Answer

Geothermal plants use the Earth's heat to produce steam. The steam spins turbines to create electricity, just like in a windy or water-filled place.

Question 14

Can cars run on renewable energy?

Accepted Answer

Yes, cars can run on renewable energy by using electricity from solar or wind power plants. Some cars also use biofuels made from plants.

Question 15

What are solar panels made of?

Accepted Answer

Solar panels are made of many small units called solar cells, usually made from materials like silicon. These cells catch sunlight and turn it into electricity.

Question 16

Can we use renewable energy at home?

Accepted Answer

Yes, people can put solar panels on their roofs or use small wind turbines in their yards to make their own electricity.

Question 17

Why don't we use renewable energy all the time?

Accepted Answer

Sometimes the wind doesn't blow or the sun doesn't shine, so we can’t always make renewable energy. That’s why we still use other kinds of energy.

Question 18

What are some challenges of using renewable energy?

Accepted Answer

One challenge is storing the energy for when it's not sunny or windy. Also, some places don't have enough space to build large wind or solar farms.

Question 19

How does renewable energy help animals?

Accepted Answer

Renewable energy helps keep the air clean, which is good for animals. Less pollution means animals have cleaner places to live and healthier food.

Question 20

Can schools use renewable energy?

Accepted Answer

Yes, schools can use solar panels or wind turbines to get electricity. This can help save money and teach kids about clean energy.
