Essential Question: What do the different energy resources have in common? What is
different?
Topic: Energy ResourcesEssential Question: What do the different energy resources have in common? What is different?
• When we use electricity in our home, the electrical power was probably generated by burning coal, by a nuclear reaction, or by a hydroelectric plant at a dam. Therefore, coal, nuclear and hydro are called energy sources.

• Energy sources are divided into two groups.– Renewable (an energy source that
can be easily replenished) – Nonrenewable (an energy source
that we are using up and cannot recreate).

• Advantage- A good reason to do or use something.– Example: The advantage of using a
calculator is math is quicker.
• Disadvantage- The reasons why doing something would be bad.– Example: The disadvantage of using
a calculator is you could punch in the number wrong and not know it.

Examples of Renewable Energy
• Solar Energy- Solar energy is the sun’s rays (solar radiation) that reach the Earth.
• Advantages- – does not produce air
pollutants.– Low impact on the
environment.
• Disadvantages-– Sunlight is not the same
all the time.– You need a LOT of solar
panels.

Examples of Renewable Energy• Wind- energy captured
from air in motion. This is captured with the use of a windmill.
• Advantages- •Few impacts on the environment.•Reduces the amount of air pollutants
• Disadvantages-•Some people do not their looks on the land•Kills birds

Examples of Renewable Energy• Hydropower- Produces
the most amount of electricity in the U.S. Energy from moving water.
• Advantages-– Generators do not
pollute the air.– Also helps stop floods
from rivers.• Disadvantages-
– Stops the migration of fish
– Could change water temperature
– Could impact plants and animals next to plant.

Examples of Renewable Energy• Geothermal- Energy
from the heat inside the Earth. Heat is always coming out of the Earth.
• Advantages- – Does not pollute
the air– Earth is always
hot so never going to run out
• Disadvantages-– Have to find a
place to drill (time consuming)
– Wells could stop producing steam
Topic: Energy ResourcesEssential Question: What do the different energy resources have in common? What is different?
Examples of Renewable Energy• Biomass- The burning of
organic material made from plants and animals . Burning releases heat which is energy.
• Advantages- – Alcohols are basically
clean burning– Can be found
anywhere
• Disadvantages-– Depending on what is
burned, could lead to global warming
– A lot less energy is released than other types of energies.

Examples of Nonrenewable Resources • Fossil Fuels-
– Include Coal, Oil and Natural Gas.
– Formed from the remains of plants and animals over millions of year.
• Advantages-– Creates HUGE amounts of
energy.– Power stations can be
made pretty much anywhere.
• Disadvantages-– Creates a HUGE amount of
pollutants– Contributes to Green
House Gases– Destroys land from mining.

Examples of Nonrenewable Resources • Nuclear- Made
from the splitting of Uranium. Split the atoms to release the energy.
• Advantages-– Does not pollute the air– Creates LARGE amounts of
energy
• Disadvantages-– Creates radioactive waste
which could cause cancer.– Can be very dangerous
