What to Focus On
- Energy is the capacity to do work.
- Energy exists in many forms, including heat, light, electrical, chemical, and mechanical energy.
- Energy can be transformed from one form to another.
- Conventional sources have been used for a long time.
- They are formed over millions of years.
- They are non-renewable because they are consumed faster than they are formed.
- Coal is a solid fossil fuel and a major fuel for thermal power plants.
- Petroleum is a liquid fossil fuel and is refined into useful products.
- Natural gas is a gaseous fossil fuel and the cleanest conventional source.
Common Mistakes to Avoid
Natural gas is a renewable energy source because it burns more cleanly than coal and petroleum.
Biomass energy is always renewable, even if it is used carelessly.
Solar energy can be used whenever electricity is needed, so it is as dependable as coal or natural gas.
