Question 1

What is renewable energy?

Accepted Answer

Renewable energy comes from natural sources like the sun, wind, and water that can be used over and over again. Unlike coal or oil, these energy sources won't run out because they keep coming back.

Question 2

Why is renewable energy important?

Accepted Answer

Renewable energy is important because it helps protect our planet. It doesn't pollute the air and keeps nature clean and safe for everyone, including animals and plants.

Question 3

How does solar energy work?

Accepted Answer

Solar energy comes from the sun's rays. Solar panels on roofs collect sunlight and turn it into electricity we can use to power our homes and gadgets.

Question 4

What is wind energy?

Accepted Answer

Wind energy is made when wind blows and turns big, tall machines called turbines. The spinning blades of the turbine create electricity.

Question 5

What is hydropower?

Accepted Answer

Hydropower, or water power, is created by moving water. Dams are built on rivers to hold water, and when the water flows through, it turns a turbine to make electricity.

Question 6

Can renewable energy run out?

Accepted Answer

No, renewable energy won't run out because we get it from things like the sun and wind, which are always there. Unlike fossil fuels, they won't ever disappear.

Question 7

How does using renewable energy help the environment?

Accepted Answer

Renewable energy helps the environment because it doesn’t create pollution. It keeps the air and water clean, which is good for plants, animals, and people.

Question 8

Why don't we use only renewable energy everywhere?

Accepted Answer

We don’t use only renewable energy because not all places get enough sun or wind. Also, it can cost a lot of money to set up at first.

Question 9

What are some examples of renewable energy sources?

Accepted Answer

Some examples of renewable energy sources are solar energy from the sun, wind energy from the wind, and hydropower from water. These sources help us get electricity without harming the planet.

Question 10

Can cars run on renewable energy?

Accepted Answer

Yes, cars can run on renewable energy! Some cars use electricity made from renewable sources, and others use fuels made from plants.

Question 11

What is a solar panel?

Accepted Answer

A solar panel is a flat, shiny thing that catches sunlight and turns it into electricity. You often see them on rooftops soaking up the sun.

Question 12

How do wind turbines make electricity?

Accepted Answer

Wind turbines have big blades that spin when the wind blows. This spinning turns a generator inside the turbine, which makes electricity.

Question 13

Is cooking with renewable energy possible?

Accepted Answer

Yes, you can cook with renewable energy! Some people use solar ovens that work by trapping sunlight to heat and cook food outdoors.

Question 14

How can renewable energy be used at home?

Accepted Answer

You can use renewable energy at home by installing solar panels or using wind turbines if it's windy where you live. This can help power your lights and appliances.

Question 15

What is geothermal energy?

Accepted Answer

Geothermal energy comes from the heat deep inside the Earth. We can use this heat to make electricity or to heat homes in certain areas.

Question 16

Why is sun energy free?

Accepted Answer

Sun energy is free because no one owns the sun! Its light shines everywhere every day, whether we use it or not.

Question 17

How does using renewable energy help reduce global warming?

Accepted Answer

Renewable energy helps reduce global warming by not producing harmful gases that trap heat in the air. This helps keep our planet cooler.

Question 18

Can renewable energy create jobs?

Accepted Answer

Yes, renewable energy can create jobs! People are needed to build and maintain solar panels and wind turbines, and many more roles.

Question 19

What's the difference between renewable and non-renewable energy?

Accepted Answer

Renewable energy comes from sources that can be used repeatedly, like the sun and wind. Non-renewable energy comes from sources that will eventually run out, like coal and oil.

Question 20

Are there any downsides to renewable energy?

Accepted Answer

One downside is that it can be expensive to set up at first. Also, sometimes the sun doesn't shine or the wind doesn't blow, so we need other solutions for those times.
