2.
Close windows
when you cool the house
3. Open "room doors" to let the
air spread
4. Plant
trees
to give shade
1. Install a
programmable thermostat
2. Heat
slowly
and not rapidly
3. Leave windows open during daytime (in summer)
4. Do not turn off the heater, e.g. during vacation

electronics
... concerning
electronical devices
avoid using the
"stand-by"
-mode, but
turn them off
entirely (during the night and your vacation)
buy a
laptop
instead of a computer to
save energy
do not
plug
your portable devices
into the charger
for the whole night (-> it wastes energy when it is full charged)

Carlotta, Charlotte, Emily, Helen and Samuel
1. Switch your
thermostat to auto
so that it
short showers
place one lamp in a corner instead of two at the wall
Secondary and Tertiary Sector
Industry
during transport
in the industry
Most of the energy is used in the sectors
industry, transport and in households.
We waste energy, because of
ignorance
oblivion
unimportance
Transport
Advantages
wind is free
uses little land
lowest prices renewable resources
environmental
(once they are build)
no pollution
no air pollution
available in range of sizes
What could they do
Save Energy?
buy more expensive "premium efficiency motors" to ultimately reduce the costs caused by
energy waste
use natural light from outside or CFL
(Compact Fluorescent Lamp) instead of incandescent (bright) lamps
install timers or occupancy sensors

improve the quality of your air
compressor by using small and well-functioning ones
don't heat and cool always if not necessary (e.g. during the night)
in the factories?
Fracking
Direction: Save Energy
How should we drive?
filter little oil or gas leftovers
water+sand+chemicals
switch the gears
accele-rate often
start & stop abun-dantly
turn off engines in pauses
use the aircon
drive fast

The tertiary sector

trade, commerce and services
15.2 % (1,413 PJ) of the total final energy consumption
Mainly used for...
Suggestions:
employees should attend trainings
commendable manner could be honored
less power consumption
-> higher salary
tax decrease for ecofriendly products
lighting
power
Information and Communications Technology
Wind farms
a group of wind turbines in the same location used to produce electricity
mainly non-renewable energies (87%)
oil (35%)
gas (20%)
Energy consumption by type
only 11% renewable
biomass (6%)
install a solar water heater
use cold water
wash only full loads of dishes & clothes
buy energy-efficient bulbs
dishwasher's drying (-> air dry dishes & clothes)
wash every day & after every meal
activate lamps during night night and vacation (-> turn them off if you leave the room)

Elec
Onshore
largest onshore windfarms are in Germany, China and the USA
Advantages:
2-3 month payback
cheaper foundation than offshore
turbines last for around 20 years
Disadvantages:
the Noise
destroys the view of the landscape
windfarm in Druiberg
Offshore
most of the offshore wind energy in europe
first offshore windfarm in Denmark, 1991
Advantages:
offshore turbines are stronger than onshore
higher and more constant wind speed
Disadvantages:
expensive to built
difficult to maintain
windfarm near Kopenhagen, Denmark
Disadvantages
unreliable, wind is not constant
less electricity
destroys the countryside
the noise
pollution produced by production
Birds, bats and other flying creatures die by flying into the turbines
strip mining
win cole with the help of digger
afterwards lake
mine
sometimes strip mining
deeper rock bed
gives more energy because of higher concentration
jack-up rig
oil rig
semi-submersible
floating platform
drillship
oil deposit or sea of oil (similar to gas)
possible on-, and offshore
onshore
offshore
oil spill gulf of Mexico
firstly oil lack did not repair that right
afterwards explosion of the oil rig
800 million liter
Conclusion:
no exhaust of fumes and CO2
while driving, less energy is consumed
production of batteries is very energy-wasting
recycling is expensive and harmful
much CO2 is emitted
History
one of the first energy resources
windmills at the beginning of the Islamic civilization (7^th century)
http://www.bbc.co.uk/schools/gcsebitesize/science/ocr_gateway/energy_resources/energy_from_the_sunrev3.shtml
July, 1887 first windmill for producing electricity
first automatically wind turbine by Charles F. Brush
Hydropower
What is Hydropower?
the electricity or power that is generated from the energy of moving water
"hydro" means water
renewable source of energy
constantly refilled by the water cycle, specifically precipitation
most widely useform of renewable energy
History
farmers used waterwheels to grind wheat into flour
early 1800's factories made use of the waterwheels to run machines
late 19^th century hydropower used to generate electricity
waterwheels and -mills used for irrigation and mining
1830's hydropower provided energy for transportation up and down steel hills
1879 first hydroelectric power plant was built at the Nigeria Falls
Pro
sun is one of the greatest energy sources (produces 10.000 times more energy than needed daily)
for humans it’s usable with modern solar technology
possibility to convert electricity in heat
electricity and heat generation without harmful consequences for the environment
own production of energy more independent
solar systems have a “life expectancy” of more than 20 years
Contra
success depends on weather, seasons and location
intensity of radiation
at the moment very expensive (not everyone is able to pay a solar cell)
Bioenergy
organic materials like plants or animals used as an energy source
general information
16% of the worlds electricity
it saves 600m tonnes of carbon emission per year
2-6 grams of carbon per kilowatt
almost twice the total amount the so far unratified global warming Kyoto Protocol treaty is designed to save
it takes 8-15 years to be built
statistics
435 nuclear power plants in 31 countries
in Germany(9):
Kernkraftwerk Brokdorf (KBR)
Kernkraftwerk Emsland (KKE)
Kernkraftwerk Grafenrheinfeld (KKG)
Kernkraftwerk Grohnde (KWG)
Kernkraftwerk Gundremmingen (KGG) Block B
Kernkraftwerk Gundremmingen (KGG) Block C
Kernkraftwerk Isar (KKI) Block 2
Kernkraftwerk Neckarwestheim (GKN) Block 2
Kernkraftwerk Philippsburg (KKP) Block 2

pros
cons
countering climate change, oil shocks and landscape destruction by windmill farms
safe and available energy source
saves carbon emission
well-known technology
generates eclectricity at a smilar cost to natural gas
massive costs
does not grow fast enough to combat global warming
does not suit everybody's needs
unsafe (Chernobyl, ...)
takes a long time to be built (8-15y) and it takes the same time to repay the financial and carbon investments later
of a nuclear power reactor
construction
Chernobyl
Fukushima
General
no fuels like mineral oil, coal or petroleum gas
energy sources like timber, straw , grasses, cereals
bioenergy is like solar energy in an herbal form
Advantages
Disadvantages
efficient use in heating stations
pressure for ground and water
competition of the raw materials
good for the environment
use of garbage
inexhaustible sources
high variety of energy sources
Examples
Look into the future
Advantages
cheapest method of generating energy
store energy
waste less energy
dams control flooding and water supply
hydropower plants are dependable, last long
maintenance is cheap
source is clean
reservoirs can also offer leisure activities
Disadvantages
become more expensive
wildlife can be changed or destroyed
26.April 1986
Ukraine - Chernobyl
2 explosions,Ultimate MCA - a lot of radioactive radiation (it causes death and cancer)
30 victims --> two died on the night and the other 28 within weeks after
many people could not flie fast enough, others came back early
2011 it was officially declared a tourist attraction
