Energy ResourcesRenewable and Non Renewable
Energy resources are natural resources that
people can turn into other forms of energy in
order to do useful work.
Non Renewable Energy Resources are resources
that cannot be replaced after they are used or
can be replaced only over thousands or millions
of years.
Renewable Resources are replaced over a short
period of time.
Energy Resources
Energy resources are natural resources that
people can turn into other forms of energy in
order to do useful work.
Non Renewable Energy Resources are resources
that cannot be replaced after they are used or
can be replaced only over thousands or millions
of years.
Renewable Resources are replaced over a short
period of time.
Energy Resources
Non Renewable Energy Resources
Fossil Fuels – Coal, Petroleum, and Natural Gas•Main source of electric energy
• Formed from the buried remains of plants and animals that lived long ago
• Generate electricity by burning fossil fuels
Nuclear Energy• Energy comes from radioactive
elements
• Generates thermal (heat) energy by boiling water to produce steam
Solar Energy •sunlight is changed into electric or thermal energy through solar cells.
•cannot be used up
Renewable Resources
Energy From Water•Kinetic / Mechanical Energy from falling water changes to electrical energy
•Falling water turns turbines & turbines give off electrical energy through a generator
Wind Energy•Kinetic / Mechanical Energy from passing winds change to electrical energy
•Winds turn turbines & turbines give off electrical energy through a generator
Geothermal Energy – Thermal Energy caused
by heating of the Earths crust
• ground water heats up and forms geysers
Powerplants put water into the ground, wait for it to heat up, water comes up as steam, steam turns generator to change mechanical energy to electrical
BioMass – burning of orgnanic matter to release usable energy• Plants use and store energy from the
sun through photosynthesis
