The Sun - Original Source of Energy
The sun is the original source of energy for many energy resources:
Solar power
- Solar power comes directly from the Sun.
Fossil fuels
- Fossil fuels are made of decayed plants and animals, which originally got their energy from the Sun.
- Plants captured this energy through photosynthesis.
- And it then passed along food chains to animals.
Wind power
- Winds are created by differences in air pressure.
- Differences in air pressure arise because of air being unevenly heated by the Sun.
Wave energy
- Waves are created by winds, which are created by the Sun.
Hydroelectricity
- Hydroelectric power is produced by dams.
- Water builds up behind the dam due to rain, which is produced by the water cycle, which is driven by the Sun or pumped up using electricity from other sources.
