The types of energy in our world Energize! The types of energy in our world
Renewable Resource: A resource we get from the earth, that we can run out of, but we can always get more of. Vegetables Fruits Trees Plants Animals
Nonrenewable Resource: A resource we get from the earth, that we can run out of someday. Once these resources are gone, we can NEVER get them back again in our lifetime. Precious gems and minerals Extinct animals/plants Fossil fuels Petroleum oil Natural gas Coal Propane
Fossil Fuels takes millions of years to form (make) animals and plants die and are buried under layers of sedimentary rock Types of fossil fuels: coal natural gas oil Gasoline is NOT a fossil fuel but fossil fuels are used to make gasoline/petroleum
Examples nonrenewable resources
More examples of other types of thermal (heat) energy that do not use fossil fuels
Inexhaustible Resource: A resource we get from the earth, that we will never run out of. Sun Water Wind Dirt
Solar Energy comes from the sun natural resource does NOT cause pollution cheap…sun’s rays are free solar panels can be expensive inexhaustible resource (never used up)
Examples of Solar energy
Wind energy comes from the wind natural resource does not cause pollution cheap, wind is free unreliable because sometimes the wind does not blow wind farms becoming more popular inexhaustible resource (never used up)
Examples of wind energy
Hydro Energy comes from moving water natural resource does not cause pollution cheap, water is free unreliable because sometimes water is not available inexhaustible resource (never used up)
Examples of hydro energy long ago
Static Energy comes from friction manmade and natural does not cause pollution cheap, rubbing 2 surfaces together not powerful enough for human to always use inexhaustible resource (never used up)
Examples of Static Energy sometimes called “static electricity”
Chemical Energy comes from batteries or combustion manmade from natural resources expensive to create causes pollution sometimes If using fossil fuels to make researching new ways to make (wind, water) both inexhaustible and nonrenewable depending on how its made
Examples of Chemical Energy
Batteries
Chemical Energy comes from food that an animal eats from natural resources
Chemical Energy
Geothermal Energy Comes from inside the Earth Heat, steam, and magma found INSIDE the Earth Natural resource Does not cause pollution Free from Earth, materials to get it out are expensive Inexhaustible, but not found everywhere
Geysers (steam)
Biofuels Comes from plants and algae Can come from animals feces Natural resource Does not cause pollution Cheap, but mainly used by farmers Renewable, but can only be used in certain types of engines
(heat energy) Thermal Energy comes from the earth – fossil fuels natural resource decaying/decomposing plants and animals that died MILLIONS of years ago causes pollution expensive to get out of the earth we will run out someday nonrenewable resource (cannot be made)
Examples of Thermal heat using nonrenewable resources
All make electric energy Hydro Thermal Solar ===Wind
