Question 2

Why is renewable energy important?

Accepted Answer

Renewable energy is important because it doesn't harm the Earth or make bad air. It helps keep our planet clean and safe for everyone!

Question 3

What is solar energy?

Accepted Answer

Solar energy is when we use sunlight to make electricity. We can catch sunlight with special panels and use it to power our lights and gadgets.

Question 4

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 and makes electricity we can use.

Question 5

What is hydropower?

Accepted Answer

Hydropower uses moving water, like rivers or waterfalls, to make electricity. The water pushes big wheels called turbines to make power.

Question 6

Can we run out of renewable energy?

Accepted Answer

No, we can't run out of renewable energy because it's always there in nature. The sun, wind, and water are always around us!

Question 7

How does renewable energy help animals?

Accepted Answer

Renewable energy doesn't pollute the environment, so animals have clean air and water to enjoy. It helps keep their homes safe too.

Question 8

What is biomass energy?

Accepted Answer

Biomass energy comes from natural materials like plants and animal waste. We can burn these materials to make heat or electricity.

Question 9

Are electric cars part of renewable energy?

Accepted Answer

Electric cars use electricity instead of gasoline. If we charge them with renewable energy, like from wind or solar, then they are part of renewable energy.

Question 10

What are some examples of renewable energy sources?

Accepted Answer

Some examples are solar power from the sun, wind power from the wind, and hydropower from water. They all help make clean energy!

Question 11

How can we use sunny days to make energy?

Accepted Answer

We can use special panels called solar panels to catch sunlight. These panels turn sunlight into electricity that we can use at home or school.

Question 12

Why is wind a good source of energy?

Accepted Answer

Wind is free and blows everywhere, making it a great source for energy. Plus, wind energy doesn’t make any pollution, keeping the air clean.

Question 13

What does 'renewable' mean?

Accepted Answer

Renewable means something we can use over and over without it running out. Like the sun's light or wind blowing, they never stop!

Question 14

Can renewable energy make enough power for everyone?

Accepted Answer

Yes, renewable energy can make enough power for everyone. As technology gets better, we can use more of it to power houses, schools, and more.

Question 15

What are solar panels made of?

Accepted Answer

Solar panels are made of materials that can catch sunlight. They have special cells inside that turn sunlight into electricity.

Question 16

How do kids use renewable energy?

Accepted Answer

Kids can help by turning off lights when leaving a room and using toys that charge with sunlight. This way, they are using renewable energy and saving power.

Question 17

What is geothermal energy?

Accepted Answer

Geothermal energy comes from the heat inside the Earth. We can use this heat to make electricity and warm up our homes.

Question 18

Can wind turbines work on calm days?

Accepted Answer

Wind turbines need wind to spin their blades. On calm days, when there's no wind, they can't make electricity.

Question 19

Is renewable energy expensive?

Accepted Answer

At first, renewable energy can be a bit costly to set up. But over time, it can save money because the sun and wind are free!

Question 20

Can we see renewable energy in action?

Accepted Answer

Yes, we can see solar panels on roofs and wind turbines spinning in windy areas. They show us how we use renewable energy every day.
