Sources-of-Energy

What will you learn

• Our energy requirements increase with our standard of living.

• In order to fulfil our energy requirements, we try to improve the efficiency of energy usage and also try and exploit new sources of energy.

• We also need to look for new sources of energy because the conventional sources of energy like fossil fuels are in danger of getting exhausted soon.

• The energy source we select would depend on factors like the ease and cost of extracting energy from the source, the efficiency of the technology available for using that source of energy and the environmental impact of using that source.

• Many of the sources ultimately derive their energy from the Sun.
