What is our major source of energy ? Our major source of energy comes from fossil fuels.

Is our major source of energy limited ? Why / why not ? Yes, it is. Because power demand is increasing very rapidly , fossil fuels will be exhausted within a relatively short time .

How many sources of energy are mentioned in the text ? What are they ? Five sources of energy are mentioned in the text. They are nuclear power, solar energy, water power, wind power, geothermal heat.

Which source of energy do you think has the most potential? I think solar energy is the most potential.
