Learning Targets

• I Can

⮚ predict the availability of energy resources

as population size and supply/demand

changes using the terms efficiency and

conservation.

⮚ predict the effects of long-term use of

renewable energy resource and determine

whether it is a better sustainable practice.

Utilization Efficiencies

Today's average new home uses half the fuel required

in a house built in 1974.Reducing air infiltration is

usually the cheapest, quickest, and most effective way

of saving household energy.

According to new national standards:New washing

machines will have to use 35% less water in 2007.Will

cut U.S. water use by 40 trillion liters annually.

Conservation

Energy Efficiency is a measure of energy
produced compared to energy consumed.
Thermal conversion machines can turn no
more than 40% of energy in primary fuel
into electricity or mechanical power due to

waste heat.

Fuel cells can theoretically approach 80%

efficiency using hydrogen or methane.

Hydroelectrical Power Use by State

Mini- Lesson

How does Georgia
compare to:
- Florida?
- California?
- Texas?

What do you think
accounts for these
differences?

Mini- Lesson

Hydro-electricity is when you use water
to make electricity.

Falling water has lots of kinetic energy,
which can be turned into electricity,
using a generator.

Hydropower

✔ Fuel is not burned so there is minimal pollution
✔ Water to run the power plant is provided free

by nature

✔ Hydropower plays a major role in reducing

greenhouse gas emissions

✔ Relatively low operations and maintenance

costs

✔ The technology is reliable and proven over time
✔ It's renewable - rainfall renews the water in

the reservoir, so the fuel is almost always there

Hydroelectric power is clean and is important in many regions of the world.

Hydroelectric dams change the river's ecosystem.

Hydropower utilizes the energy of falling water.

Multiple Choice

Which of the following is a disadvantage of Hydroelectricity?

Explain

• Hydroelectric power is clean and is important in many regions of the world.

• Hydroelectric dams change the river's ecosystem.

• Hydropower utilizes the energy of falling water

• radioactive waste

Passive Solar design

•uses seasonal changes in the path of the sun to
create structures that are heated by natural
means.

•Greenhouses, solariums, and sunrooms are
classic examples of basic passive solar
structures. Typically, the sun’s rays pass through
the glass windows, which absorbs and retains
the heat.

Solar Power

Mini- Lesson

During the past 25 years,
efficiency of energy capture by
photovoltaic cells has increased
from less than 1% of incident light
to more than 10% in field
conditions, and over 75% in the
laboratory.Invention of
amorphous silicon collectors has
allowed production of lightweight,
cheaper cells.Currently $700
million annual market.

Solar Power

Mini- Lesson

Photovoltaic cells capture
solar energy and convert it
directly to electrical current
by separating electrons from

parent atoms and

accelerating them across a
one-way electrostatic barrier

Efficiency checklist

●We will use this chart to rate a
renewable resource.

●1. its efficiency either percent
like 15% efficient

●Replenish rate as renewable
energy resources do
replenish. Some factors like
intermittency play a role more
than others. If intermittency
cannot be controlled than it is
a medium replenish rate

●Low rate is if it is dependent
on factors that can be wiped
out . For example, a pig
methane farm.
