Question 1

What is renewable energy?

Accepted Answer

Renewable energy comes from sources that won't run out, like the sun or wind. These sources can keep giving us energy over and over.

Question 2

Why is renewable energy important?

Accepted Answer

Renewable energy is important because it helps keep our planet healthy. It doesn't pollute the air as much as other types of energy.

Question 3

How does solar energy work?

Accepted Answer

Solar energy comes from the sun. Special panels, called solar panels, catch sunlight and turn it into electricity we can use.

Question 4

What is wind energy?

Accepted Answer

Wind energy is made when wind spins big blades on a wind turbine. The spinning blades turn the wind's power into electricity.

Question 5

How do we get energy from water?

Accepted Answer

Energy from water, or hydropower, comes from water flowing fast. The moving water turns big wheels, called turbines, to make electricity.

Question 6

What is geothermal energy?

Accepted Answer

Geothermal energy is heat that comes from inside the Earth. We can use this heat to make electricity or to warm our homes.

Question 7

Can renewable energy help stop pollution?

Accepted Answer

Yes, using renewable energy can help reduce pollution. It makes cleaner energy that doesn't dirty the air like burning coal or oil does.

Question 8

Is renewable energy expensive to use?

Accepted Answer

At first, setting up renewable energy like solar panels can cost a lot. But in the long run, it can save money because sunlight and wind are free.

Question 9

Can solar energy work on cloudy days?

Accepted Answer

Yes, solar panels can still collect some energy on cloudy days. They work best on sunny days but can still provide power when it's cloudy.

Question 10

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

Accepted Answer

Sometimes the sun isn’t shining, or the wind isn’t blowing, so it's hard to rely only on renewable energy. Scientists are working on better ways to store energy for these times.

Question 11

What are fossil fuels?

Accepted Answer

Fossil fuels are energy sources like coal, oil, and natural gas. They're called 'fossil' fuels because they're made from plants and animals that lived a long time ago.

Question 12

How does using renewable energy protect animals?

Accepted Answer

Renewable energy is cleaner and can help keep the environment healthy. This clean environment is better for animals to live in and helps protect their homes.

Question 13

Can cars use renewable energy?

Accepted Answer

Yes, some cars use electricity made from renewable energy like solar or wind. Electric cars can be powered by renewable energy instead of gasoline.

Question 14

What is biomass energy?

Accepted Answer

Biomass energy comes from plants and waste. It can be used to make electricity and is a way to use nature’s leftovers to create power.

Question 15

How can wind energy help the environment?

Accepted Answer

Wind energy makes electricity without polluting the air. It helps keep the planet clean and reduces the need for fossil fuels.

Question 16

Can we run out of renewable energy?

Accepted Answer

No, renewable energy comes from things we won't run out of, like sunlight and wind. As long as the sun shines and the wind blows, we’ll have renewable energy.

Question 17

What is a wind turbine?

Accepted Answer

A wind turbine is a tall machine with big blades that spin in the wind. This spinning turns energy from the wind into electricity we can use.

Question 18

How do solar panels help the planet?

Accepted Answer

Solar panels make clean energy from sunlight without making pollution. By using them, we help keep the Earth’s air cleaner.

Question 19

What do we use renewable energy for?

Accepted Answer

We use renewable energy to power things like lights, computers, and cars. It helps us do everyday things without harming the planet.

Question 20

Is hydropower available everywhere?

Accepted Answer

Hydropower works best in places with lots of flowing water, like rivers or waterfalls. Not every place has enough water for it, so it's used where it’s possible.
