Question 1

What are renewable energy sources?

Accepted Answer

Renewable energy sources are natural things we can use again and again to make power, like the sun, wind, and water. They never run out because they keep coming back, unlike coal or oil.

Question 2

Why is the sun important for renewable energy?

Accepted Answer

The sun gives us sunlight, which can be changed into electricity using solar panels. It's important because it shines all around the world and helps us create clean energy without pollution.

Question 3

How does wind create energy?

Accepted Answer

Wind turns big blades on a windmill called turbines. When these blades spin, they make electricity we can use in our homes.

Question 4

What is hydropower?

Accepted Answer

Hydropower means using moving water to make electricity. Dams are often built on rivers to help control the water flow and create energy.

Question 5

Why is renewable energy good for the planet?

Accepted Answer

Renewable energy is good for Earth because it doesn’t pollute the air and water. It's clean and helps keep our planet healthy and safe for all living things.

Question 6

What is a solar panel?

Accepted Answer

A solar panel is a flat, shiny piece that catches sunlight and turns it into electricity. You often see them on rooftops or in fields.

Question 7

Can renewable energy run out?

Accepted Answer

No, renewable energy sources like the sun and wind won't run out because they are always available. That's why they are called 'renewable'!

Question 8

Do cars use renewable energy?

Accepted Answer

Some cars can use electricity to run, which could come from renewable sources like solar or wind. These electric cars help reduce pollution and save the planet.

Question 9

How do we use sunlight to get heat?

Accepted Answer

Sunlight can be used to heat water in large tanks or spaces directly. This warm water can then be used for showers or heating buildings.

Question 10

What are wind farms?

Accepted Answer

Wind farms are places where many wind turbines are set up. Together, they make a lot of electricity from the wind, just like a big power station.

Question 11

How does water make energy?

Accepted Answer

Water makes energy when it moves fast and turns a wheel inside a machine. This moving wheel helps make electricity that we can use.

Question 12

Is renewable energy safe?

Accepted Answer

Yes, renewable energy is safe because it doesn’t cause pollution or waste. It helps us have cleaner air and water.

Question 13

Why don't we use only renewable energy?

Accepted Answer

We don't use only renewable energy yet because not everywhere can get enough sun, wind, or water all the time. But people are working on ways to use more renewable energy worldwide.

Question 14

What is geothermal energy?

Accepted Answer

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

Question 15

Can homes use renewable energy?

Accepted Answer

Yes, homes can use renewable energy by adding solar panels on the roof or getting electricity from wind turbines. This helps save money and the environment.

Question 16

How does the Earth make wind?

Accepted Answer

The Earth makes wind when the sun heats up the air. Warm air rises, and cool air rushes in to take its place, creating wind.

Question 17

Do all countries use renewable energy?

Accepted Answer

Not all countries use a lot of renewable energy yet, but many are trying to use more. Some places have more sun, wind, or water, which helps them use these resources more.

Question 18

What is biomass energy?

Accepted Answer

Biomass energy comes from plants and animals. We can burn wood or use plant material to make electricity or heat.

Question 19

Can we store renewable energy?

Accepted Answer

Yes, we can store renewable energy using batteries or other systems. This helps us use the energy even when the sun isn't shining or the wind isn't blowing.

Question 20

What is tidal energy?

Accepted Answer

Tidal energy comes from the rise and fall of ocean tides. We use machines to capture this movement and make electricity.
