TWO TYPES TWO TYPES OF RESOURCES OF RESOURCES

NON RENEWABLE RESOURCES

A nonrenewable resource is a natural resource that cannot be re-made or re-grown at a scale comparable to its consumption.

NUCLEAR ENERGYNuclear fission

uses uranium to create energy.

Nuclear energy is a nonrenewable

resource because once the uranium

is used, it is gone!

Fossil FuelsFossil fuels take millions of Fossil fuels take millions of years to form. They are the years to form. They are the product of the fossilized product of the fossilized remains of dead plants and remains of dead plants and animals that have been animals that have been exposed to the heat and exposed to the heat and pressure deep within the pressure deep within the earth’s crust. There are many earth’s crust. There are many types of fossil fuels, such as types of fossil fuels, such as petroleum (gasoline), natural petroleum (gasoline), natural gas, and coal.gas, and coal.

COAL, PETROLEUM, AND GAS

Coal, petroleum, and natural gas are considered nonrenewable

because they can not be replenished in a short period of

time. These are called Fossil fuels.

HOW IS COAL MADE ???

HOW ARE OIL AND GAS MADE ???

RENEWABLE RESOURCES

Renewable resources are natural resources that can be replenished in a short period of time.

SOLARThe sun’s rays are used The sun’s rays are used for energy by organisms for energy by organisms

that undergo that undergo photosynthesis. Nearly photosynthesis. Nearly every organism on the every organism on the

planet gets energy through planet gets energy through photosynthesis, directly or photosynthesis, directly or indirectly. There are also indirectly. There are also

ways that people can ways that people can utilize the energy that the utilize the energy that the

sun provides. sun provides.

Geothermal energy is thermal energy

generated and stored in the Earth.Earth's geothermal energy originates from the original formation of the

planet, from volcanic activity, and

from solar energy absorbed at the

surface.

GEOTHERMALGEOTHERMAL

WIND Wind is caused by the uneven heating of the Wind is caused by the uneven heating of the atmosphere.atmosphere.

Some areas of the world, such as costal Some areas of the world, such as costal regions, have more wind than others regions, have more wind than others because the terrain of the area is relatively because the terrain of the area is relatively flat and has few obstacles to block the wind flat and has few obstacles to block the wind from blowing.from blowing.

The wind blows naturally – it is not caused The wind blows naturally – it is not caused by human activity, and it cannot be used up.by human activity, and it cannot be used up.

BIOMASSBiomass, a renewable energy source, is biological material from living, or recently living

organisms, such as wood, waste, (hydrogen) gas, and

alcohol fuels. Biomass energy is derived from five distinct energy

sources: garbage, wood, waste, landfill gases, and alcohol fuels.

HYDROELECTRIC

Hydroelectricity is the term referring to

electricity generated by hydropower ; the

production of electrical power through the use of the gravitational force of falling or flowing water.

It is the most widely used form of renewable

energy.
