To determine whether each energy source is Renewable (R) or Non-Renewable (N), we look at whether the source can be replenished naturally in a short amount of time.
Step-by-Step Analysis:
1.
Oceans—Tidal: Tides are caused by the moon and sun's gravity and happen every day. They do not run out.
*
Classification: Renewable (
R)
2.
Geo-Thermal / Earth Heat: This uses heat from inside the Earth. The Earth constantly produces this heat, so it won't run out.
*
Classification: Renewable (
R)
3.
Solar (Sun): The sun shines every day and will continue to do so for billions of years. We cannot use up all the sunlight.
*
Classification: Renewable (
R)
4.
Fuel: In this context (shown as an oil rig), "fuel" refers to fossil fuels like oil and gas. These take millions of years to form and once we burn them, they are gone.
*
Classification: Non-Renewable (
N)
5.
Nuclear: Nuclear energy uses uranium. Uranium is a mineral mined from the ground. There is a limited supply of it on Earth, so it is considered non-renewable.
*
Classification: Non-Renewable (
N)
6.
Wind: Wind is caused by air moving around the planet. As long as the sun heats the Earth, there will be wind. It does not run out.
*
Classification: Renewable (
R)
7.
Hydro: This uses flowing water (like rivers or dams) to make electricity. The water cycle keeps refilling the rivers with rain and snow.
*
Classification: Renewable (
R)
8.
Coal: Coal is a rock formed from ancient plants over millions of years. Once we dig it up and burn it, it is gone forever.
*
Classification: Non-Renewable (
N)
Final Answer:
* Oceans—Tidal:
R
* Geo-Thermal / Earth Heat:
R
* Solar (Sun):
R
* Fuel:
N
* Nuclear:
N
* Wind:
R
* Hydro:
R
* Coal:
N
