Be Resourceful! Energy resource a natural resource that humans
use to generate energy. 2 types Renewable resources that can be
replaced quickly Nonrenewable resources that can not be replaced
easily because they take a long time renew. 2
Slide 3
1. Fossil Fuels nonrenewable energy that forms from the remains
or organisms that lived long ago. Release energy when burned. The
energy can be converted to electricity. 3 Main types of fossil
fuels 1. Petroleum liquid also known as crude oil Liquid that comes
from the ground. Diesel fuels and gasoline. 2. Natural gas comes
from the ground Used for cooking and heating. Methane, Butane and
Propane. 3. Coal - solid comes from the ground. Once used to heat
homes and run transportation. 2 Types of Nonrenewable Resources

Slide 4
Formation of Petroleum and natural gas? 1. Marine organisms die
and settle to the bottom. 2. Layers of sediment slowly bury the
dead marine organisms. 3. Heat and pressure slowly turn the remains
into petroleum and natural gas. 4. Petroleum and natural gas flow
through rocks, where they become trapped and concentrated. Humans
then extract the fuel. 4
Slide 5
Formation of Coal 1. Partially decayed swamp plants sink to the
bottom and change into peat. Looks like rotting wood. 2. As
sediment buries the peat, heat and pressure change peat into
lignite. 3. As sediment builds, heat and pressure change the
lignite into bituminous coal. 4. Heat and pressure continues to
change the bituminous coal into anthracite coal. 5
Slide 6
Problems with Fossil Fuels Burning them produces pollution.
Releases carbon dioxide into atmosphere = Increase in global
warming. Creates smog and acid rain. Oil spills
Flammable/combustible 6
Slide 7
2 Types of Nonrenewable Resources 2. Nuclear Fuel the energy
released when the nuclei of atoms are split or combined. Nuclear
fission split an atom We use Uranium as the fuel, which is
nonrenewable! Nuclear fusion combine atoms together The suns energy
is a result of nuclear fusion 7

Nuclear Fuel 8
Slide 9
Produce dangerous waste that is radioactive. Harmful radiation
may also be released into the environment. Can cause cancer from
radiation if the core melts. 9 Dangers of Nuclear Fuels

Slide 11
Turn, Turn, Turn Wind energy uses the force of moving air to
drive an electric generator or do other work. Wind is created by
the suns uneven heating of air masses in earths atmosphere. Wind is
renewable! Turbines or windmills generate electricity by the moving
blades. They do not generate a lot of air pollution! 11
Slide 12
Moving Water Moving water has kinetic energy! Hydroelectric
energy electrical energy that is produced by moving water. The sun
powers the water cycle Water is renewable! 12
Slide 13
Let the Sunshine In Solar energy the energy received by Earth
from the sun in the form of radiation. Solar panels to heat homes.
Photovoltaic cell used to convert solar energy into electricity -
used in solar calculators 13
Slide 14
Biomass Fuels Biomass organic matter from plants and animal
waste that contains chemical energy. This energy can be used to
cook food, provide warmth, power engines. Biomass sources include
trees, crops, alcohol, animal waste and peat. Biomass Fuels are
renewable! The sugars in corn and sugarcane are converted to
ethanol which can be burned as a source of fuel in cars. 14
Slide 15
Geothermal Energy Geothermal energy energy produced by heat
from earths interior. Examples include: geyser, hot springs,
volcanoes. Geothermal power plants pump the steam or hot water from
underground to spin turbines that generate electricity. The
electricity is generated from water heated by magma pumped beneath
Earths surface. 15

Lesson 5: Managing Resources 16
Slide 17
Effective Ways to Manage Resources Stewardship the careful and
responsible management of resources. Conservation the protection
and wise use of natural resources. Recycling reduces the use of new
resources. Reduce Reuse Recycle 17
