that extracts energy from fluid flow and converts it to useful work

• Generator - a device that converts mechanical energy to electrical energy

• Renewable

• Nonrenewable

NONRENEWABLE RESOURCES

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

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 ???

NUCLEAR ENERGYNuclear fission

uses uranium to create energy.

Nuclear energy is a nonrenewable

resource because once the uranium

is used, it is gone!

Getting electricity from steam…

Pressure generated by steam pushes through a turbine, spinning it

Spinning turbines use kinetic energy to turn a magnet inside a large

generator, creating a flow of electrons.

RENEWABLE RESOURCES

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