Transcript of Energy Resources and

any material from living things that can be used as an energy source
Stem, Tubines, Generators, Electricity
If we keep pulling death from the ground, we will reap death from the skies.”
- Van Jones
How Does It Work?
Biomass
How Does It Work?
Examples: Burning wood, burning discarded plant material.

Crops-ethanol-fuel


Disadvantage: Air pollution

Types of Energy Resources
Nonrenewable and Renewable
heat energy from inside Earth
Geothermal Energy
Non renewable resources are used much faster than it can be replaced.

Renewable resources either can be replaced as it is used or cannot be used up.

Nonrenewable Energy Resources
Most of US energy fossil fuels
fossil fuels decayed remains
coal, petroleum, natural gas, nuclear
Advantage: Produces large amounts of energy when burned
Disadvantage: Pollution

Renewable Energy Resources
Produces natural hot springs and
geysers.

Using geothermal energy requires
a location that is over volcanically
active ground.

Majority of Iceland relies on
geothermal energy
Energy Resources and Their Environmental Impact
Wind, Soloar, Biomass, Hydroelectric, Geothermal
Disadvantage: Expensive
Advantage: Minimum pollution
Steam, Turbines, Generators, Electricity
Lesson Review
Which of the following is a nonrenewable energy resource?
A) Coal B) Wood C) Wind D) Biomass

Which source of energy depends on moving water?
A) geothermal b) hydropower c) solar d) biomass

Which of the following does not release Carbon dioxide when it is used as an energy resource?
A) petroleum B) ethanol C) coal D) wind

Why is the use of geothermal energy limited?
A)only in areas that have volcanic activity
B)only in areas that receive great deal of sunlight
Energy Resource
9/14-9/15/16
Most of US energy fossil fuels
fossil fuels decayed remains
Fossil fuels: 1) fuel is burned 2) steam turns turbines 3) electricity is generated
Wind Power: 1) Wind turns the blades 2) electricity is generated 3)unused energy goes to grid

Solar Power: 1) solar panels captures sunlight 2) converter transforms light to electric energy
Hydroelectric: 1) water is released 2) water turns turbines 3) generates electricity
Geothermal Power: 1) heat from earth creates steam 2) steam turns turbine 3) generates electricity
What are fossil fuels?
How does it
work?
How much energy
do we use?
92% of US uses Nonrenewable Resources; 8% Renewable Resources.
