Energy Sources . Objectives: The student will be able to demonstrate understanding of: • Explaining that energy is needed to make . objects work.
Nonrenewable Energy Sources. Sources that cannot be replaced once used. Fossil Fuels. Coal. Oil. Natural Gas. Alternative Energy: Any fuel that is not identified as a fossil fuel
1. Emergence of Alternative Sources. Alternative energy. Supplement / replace an energy source with a new source: The existing energy source judged to be no longer sustainable.
Energy that is available for release from chemical reactions. The chemical bonds in a matchstick store energy that is transformed into thermal energy when the match is struck. Examples of Chemical Energy What is Thermal Energy?
Current definitions - secondary energy “Secondary energy should be used to designate all sources of energy that results from transformation of primary sources” UN, Concepts and Methods in Energy Statistics, New York, 1982.
There are other sources of energy such as: Solar power, wind power, hydroelectric power and wave power. These photographs show ways of getting energy from four different energy sources, can you name them?
Scientists predict that we will use up our fossil fuels in the next 70 years. SOLUTION: Use less (conservation) so it will last longer. This will give us time to continue to research and develop our renewable energy sources so they are more affordable and can be used by more people

Plants as Sources of Energy Through the process of photosynthesis, plants have the capacity to capture and utilize energy, derived from the Sun, along with carbon from the Earth’s atmosphere and nutrients from our soils to generate biomass.
Cells don’t get Energy directly from food, it must be broken down into:ATP-Adensosine TRIphosphateATP = a form of energy one can immediately use, it is needed for cells to function & muscles to contract
What is an Energy Resource ? Aplace where energy originates (comes from). Energy transformations can be traced back to a primary source of energy or ENERGY RESOURCE.
Energy Sources Fossil Fuels Coal, Oil and Gas are called "fossil fuels" because they have been formed from the fossilized remains of prehistoric plants and animals.
