Question 1

What are renewable energy sources?

Accepted Answer

Renewable energy sources are natural things we can use to make electricity or power and they won't run out. Examples include sunlight, wind, water, and plants.

Question 2

Why is the sun important for renewable energy?

Accepted Answer

The sun gives us light and heat, which we can use to make electricity. Solar panels catch sunlight and turn it into energy we can use for our homes and gadgets.

Question 3

How do windmills make electricity?

Accepted Answer

Windmills have big blades that spin when the wind blows. This spinning turns a machine inside the windmill that makes electricity for us to use.

Question 4

Can water make electricity too?

Accepted Answer

Yes, water can make electricity! Dams use moving water to spin big wheels called turbines, and this makes electricity.

Question 5

What is solar energy?

Accepted Answer

Solar energy is when we use sunlight to make power. We use special panels, called solar panels, to catch sunlight and turn it into electricity.

Question 6

Is wood a renewable energy source?

Accepted Answer

Yes, wood is a renewable energy source because trees can be replanted after we cut them down. We can burn wood to make heat and power.

Question 7

Why is wind energy good for the environment?

Accepted Answer

Wind energy is good because it doesn't make dirty air or use up natural resources. It's clean and can be used over and over again without harming the earth.

Question 8

What is geothermal energy?

Accepted Answer

Geothermal energy comes from heat inside the earth. We use this heat to warm buildings or create electricity.

Question 9

How does hydropower work?

Accepted Answer

Hydropower uses the energy from moving water. It uses dams to collect water and let it flow through turbines to make electricity.

Question 10

Can we use the ocean to make energy?

Accepted Answer

Yes, we can use waves and tides in the ocean to make energy. The movement of water can turn turbines that help make electricity.

Question 11

Do renewable energy sources pollute the air?

Accepted Answer

No, renewable energy sources don't pollute the air. They are cleaner than other energy sources that burn things like coal and oil.

Question 12

Why do we need renewable energy?

Accepted Answer

We need renewable energy to help protect our planet. It's cleaner and won't run out like other energy sources might.

Question 13

How does biomass energy work?

Accepted Answer

Biomass energy uses plants and other natural materials to make power. We can burn these materials to create heat and electricity.

Question 14

Are batteries important for renewable energy?

Accepted Answer

Yes, batteries store energy from sources like solar panels and windmills. It helps us have power even when the sun isn't shining or the wind isn't blowing.

Question 15

Can cars use renewable energy?

Accepted Answer

Yes, some cars run on electricity made from renewable energies like solar or wind. These cars are better for the environment because they don't need gasoline.

Question 16

Why don't we use more renewable energy everywhere?

Accepted Answer

Sometimes it's expensive to set up and not everyone has the right weather for it. But people are trying hard to use more renewable energy because it's good for the earth.

Question 17

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

Accepted Answer

Renewable energy comes from things that can be replenished, like the sun or wind. Non-renewable energy comes from things that can run out, like coal and oil.

Question 18

Can we use renewable energy at home?

Accepted Answer

Yes, many homes use solar panels to make electricity from the sun. Some even use small wind turbines if they get a lot of wind.

Question 19

What is a wind farm?

Accepted Answer

A wind farm is a group of big wind turbines all together in one area. They work together to make a lot of electricity.

Question 20

Why is it important to save energy, even with renewable sources?

Accepted Answer

Saving energy helps reduce waste and makes sure we have enough to go around. Even though renewables are plentiful, being smart about energy use is always a good idea.
