Question 1

What is sustainable energy?

Accepted Answer

Sustainable energy is the kind of energy that doesn't run out and is good for our planet. It comes from sources like the sun, wind, and water.

Question 2

Why is sustainable energy important?

Accepted Answer

Sustainable energy is important because it helps keep our planet clean and healthy. It doesn't pollute the air and water, and we can use it forever without running out.

Question 3

What is solar energy?

Accepted Answer

Solar energy comes from the sun. We use special panels called solar panels to catch sunlight and turn it into electricity we can use in our homes and schools.

Question 4

How does wind energy work?

Accepted Answer

Wind energy uses big windmills called turbines to catch the wind. The wind makes the blades spin, turning the movement into electricity.

Question 5

What is hydroelectric energy?

Accepted Answer

Hydroelectric energy comes from moving water, like rivers or waterfalls. The water flows through machines called turbines, which turn and make electricity.

Question 6

What is geothermal energy?

Accepted Answer

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

Question 7

How is sustainable energy different from fossil fuels?

Accepted Answer

Sustainable energy comes from natural sources that won't run out, like the sun, wind, and water. Fossil fuels, like coal and oil, come from deep underground and can run out and pollute the planet.

Question 8

What are fossil fuels?

Accepted Answer

Fossil fuels are made from plants and animals that lived millions of years ago. They include coal, oil, and natural gas, and they're often used for energy, but they're not as clean as sustainable sources.

Question 9

Why should we use more sustainable energy?

Accepted Answer

Using more sustainable energy helps protect the Earth from pollution and climate change. It also means we have a forever source of energy that won't disappear.

Question 10

What are some examples of sustainable energy sources?

Accepted Answer

Some examples include solar energy from the sun, wind energy from the air, and hydroelectric energy from flowing water.

Question 11

Can wind energy be used everywhere?

Accepted Answer

Wind energy works best in places where it's windy. Some places may not have enough wind to make it work well, so they might use other types of sustainable energy.

Question 12

How do solar panels work?

Accepted Answer

Solar panels take sunlight and turn it into electricity. They have special parts inside that let sunlight create electricity we can use.

Question 13

Is using water for energy bad for fish?

Accepted Answer

Sometimes, building big dams for hydroelectric energy can be tough on fish. But there are ways to make it safer, like building fish ladders so fish can swim around the dam.

Question 14

How can we use less energy at home?

Accepted Answer

We can turn off lights when we're not using them, use energy-saving light bulbs, and unplug devices when they're not in use. This helps save energy and keeps our planet healthier.

Question 15

What is biomass energy?

Accepted Answer

Biomass energy comes from plants and waste materials. We burn these materials to make heat and electricity, but it's important to use them carefully so they are still good for the environment.

Question 16

Are electric cars better for the environment?

Accepted Answer

Yes, electric cars are better because they don't have tailpipes, so they don't pollute the air. They run on electricity, which can come from sustainable energy sources.

Question 17

Can we use the ocean for energy?

Accepted Answer

Yes, we can use the power of ocean waves and the tides to create electricity. This is called marine energy, and it's another way to use water for sustainable energy.

Question 18

What does it mean to conserve energy?

Accepted Answer

Conserving energy means using less energy by being smart about how we use it. This can help save resources and keep the environment clean.

Question 19

How does sustainable energy help fight climate change?

Accepted Answer

Sustainable energy doesn't produce as much pollution as fossil fuels. By using less fossil fuel and more sustainable energy, we can reduce the gases that cause climate change.

Question 20

Can kids help with sustainable energy?

Accepted Answer

Yes, kids can help by learning about sustainable energy and sharing what they learn. They can also remind their families to save energy by turning off lights and using less water.
