Question 1

What is renewable energy?

Accepted Answer

Renewable energy comes from natural sources that can be used over and over again, like the sun or wind. It's different from energy sources like coal that can run out.

Question 2

Why is renewable energy important?

Accepted Answer

Renewable energy is important because it helps keep our planet clean and doesn’t run out. It also helps reduce pollution and stops the Earth from getting too warm.

Question 3

How does solar energy work?

Accepted Answer

Solar energy uses sunlight to make electricity. Solar panels catch the sunlight and turn it into power we can use for lights, TVs, and more.

Question 4

What is wind energy?

Accepted Answer

Wind energy is made by using the wind to turn big blades on a windmill. This spinning creates electricity that we can use to power our homes.

Question 5

Can water create energy?

Accepted Answer

Yes, energy from water is called hydroelectric power. Water moving fast or falling from a height turns big wheels in a dam to make electricity.

Question 6

What are the benefits of using renewable energy?

Accepted Answer

Renewable energy is clean and safe for the environment. It also never runs out, so we don’t have to worry about running out of power.

Question 7

Why do we need to find alternatives to fossil fuels?

Accepted Answer

Fossil fuels like coal take millions of years to form and can pollute the air. Renewable energy is cleaner and won’t run out.

Question 8

How is energy from the sun different from energy from coal?

Accepted Answer

Energy from the sun is clean and renewable; we can keep using it without making the Earth dirty. Coal, however, can pollute and will eventually run out.

Question 9

What is geothermal energy?

Accepted Answer

Geothermal energy comes from the heat inside the Earth. It can be used to heat houses or make electricity.

Question 10

Are there any downsides to renewable energy?

Accepted Answer

Sometimes, the sun doesn’t shine or the wind doesn’t blow, so we need ways to store energy for later. But overall, renewable energy is very good for the planet.

Question 11

How can we store renewable energy?

Accepted Answer

We can store renewable energy in big batteries. This way, we can use it when the sun isn’t shining or the wind isn’t blowing.

Question 12

What are solar panels made of?

Accepted Answer

Solar panels are made of special materials that catch sunlight and turn it into electricity. They are usually flat and shiny so they can catch lots of sun.

Question 13

Can renewable energy be used in cars?

Accepted Answer

Yes, cars can use renewable energy! Some cars run on electricity from solar and wind power instead of gas.

Question 14

Does renewable energy help with pollution?

Accepted Answer

Yes, renewable energy produces little to no pollution compared to fossil fuels. This helps keep the air and environment cleaner.

Question 15

How are wind turbines different from traditional windmills?

Accepted Answer

Wind turbines are used to make electricity, while traditional windmills were used to grind grain or pump water. They both use wind, but for different jobs.

Question 16

Can solar panels still work on cloudy days?

Accepted Answer

Yes, solar panels can still make some electricity on cloudy days, but not as much as on sunny days. They work best when the sun is bright.

Question 17

Why do people use renewable energy if it can be more expensive?

Accepted Answer

Even though it can be expensive at first, renewable energy saves money over time by avoiding the cost of fuel. It also helps keep the planet healthy.

Question 18

What are biofuels?

Accepted Answer

Biofuels are made from plants and other organic materials. They can be used to power cars and other machines.

Question 19

How has renewable energy changed over the years?

Accepted Answer

Renewable energy has become more popular and common. New technologies have made it easier and cheaper to use.

Question 20

What can kids do to support renewable energy?

Accepted Answer

Kids can learn about renewable energy and share what they know with others. They can also help save energy at home by turning off lights when not needed.
