The matches for different forms of energy sources are as below,
- Nuclear energy – The largest non-fossil fuel source in the world
- Oil – May run out in the next 100 years
- Solar Power – Uses energy directly from the sun
- Hydroelectricity – Uses running water
<h3>What are the different energy sources?</h3>
The forms of energy that can be used to perform certain tasks, where they serve as a fuel and electricity are known as energy sources. Oil and Nuclear energy are non-renewable sources of energy.
Whereas, the solar energy and hydroelectricity are renewable and clean sources of energy. They do not cause as much pollution as the non-renewable sources.
Hence, 1-A; 2-B; 3-D and 4-C are the matches for the energy sources.
