Science P3 - Sustainable Energy
- Primary Energy Source
- Is found or occurs naturally.
- Examples include fuels
such as coal, oil, natural
gas and wood.
- Secondary Energy Source
- Is energy in a form that can be distributed easily but is
manufactured by using a raw energy resource such as a
fossil fuel or wind
- Examples of electricity, hot water used in heating streams, and stream.
- Fuels
- A fossil fuel is one that is built up over
millions of years by decay of plants and
animals remain.
- Coal, petroleum, and natural gas are all fossil fuels.
- When they burn, fossil fuels produce carbon
dioxide (CO2) and other pollutants such as
carbon particles.
- A biofuel is a renewable fuel that uses biological material,
such as recently living plant material and animal waste.
- Formulas
- Energy used = Power rating x Time
- Power = Voltage x Current
