Let’s go step by step to sort each energy source into the correct category:
Renewable Energy or
Nonrenewable Energy.
First, remember what these mean:
-
Renewable Energy: Comes from sources that won’t run out. They are naturally replaced over time — like sun, wind, water flow, heat from Earth, and tides.
-
Nonrenewable Energy: Comes from sources that take millions of years to form and will eventually run out — like coal, oil, natural gas, and nuclear fuel (uranium).
Now let’s look at each one:
1.
Biomass – This is plant or animal material used for energy. Plants can be grown again, so it’s renewable.
✔ Renewable
2.
Solar – Energy from the sun. The sun isn’t going away anytime soon!
✔ Renewable
3.
Oil – Formed from ancient dead organisms underground. Takes millions of years to make. We’re using it faster than it forms.
✘ Nonrenewable
4.
Wind – Wind blows because of weather and Earth’s rotation. It doesn’t run out.
✔ Renewable
5.
Tidal – Energy from ocean tides caused by moon’s gravity. Tides happen every day.
✔ Renewable
6.
Coal – Like oil, formed from ancient plants over millions of years. Once we burn it, it’s gone.
✘ Nonrenewable
7.
Hydroelectric – Uses flowing water (like rivers) to make electricity. Water cycles through rain and rivers constantly.
✔ Renewable
8.
Nuclear – Uses uranium, which is mined from the ground. There’s a limited amount on Earth.
✘ Nonrenewable
9.
Geothermal – Heat from inside the Earth. The Earth keeps producing heat, so this is renewable.
✔ Renewable
10.
Natural Gas – Found underground with oil. Also takes millions of years to form.
✘ Nonrenewable
Now let’s group them:
✔ Renewable Energy:
- Biomass
- Solar
- Wind
- Tidal
- Hydroelectric
- Geothermal
✘ Nonrenewable Energy:
- Oil
- Coal
- Nuclear
- Natural Gas
That’s 6 renewable and 4 nonrenewable — matches the number of boxes in the worksheet!
Final Answer:
Renewable Energy: Biomass, Solar, Wind, Tidal, Hydroelectric, Geothermal
Nonrenewable Energy: Oil, Coal, Nuclear, Natural Gas
Parent Tip: Review the logic above to help your child master the concept of renewable and nonrenewable resources worksheet elementary.
