Global Warming
Amount of CO2 – emissions
in Germany
• The climate change is currently one of the most
important concerns in the world.
• If we don´t do anything against it, the earth is
going to grow warmed
• Besides many Mediterranean regions would have
30% less amount of water
• For now the priority lies in stopping the climate
change, because it most certainly cannot be
reversed
Methane:
• Australian, British and American scientists report
that since 2007 the concentration of methane in
the atmosphere has been increasing again for
almost ten years.
• As a greenhouse gas, methane is about 25 times
as effective as CO2. Its share of the global
warming problem is currently 16 percent.
Climate change & Environmental
protection
• The issues of climate change and
environmental protection are among the most
important of our time. We will explain what
contribution you can make to protect the
environment by solar energy and how much
emission can be saved annually.
Environmental protection by solar
energy
• Solar energy is a renewable and clean energy.
• More and more solar and thermal systems
and photovoltaic systems are being installed,
for example the increase from 2007 to 2008
was 100 percent in Germany
Solar systems reduce carbon
emissions
• A conventional heating causes 603 grams of
climate-damaging carbon dioxide per kilowatt
hour.
• This gas is responsible for among other things
• As for the use of solar energy no substances are
burned, this technology saves a large amount of
emissions and protects the environment.
• The amount depends on the type of solar
collector and the solar system.

Energy generation in Germany
The electricity mix in Germany consists of very different energy
sources: coal, nuclear and renewable energy are the most
important.
In industrialized countries, is a life without electricity hardly
conceivable.
Electricity is usually generated in power plants, power
generation in Germany is now privatized.
Electricity is generated by energy forms such as heat or kinetic
energy which are converted into electrical energy.
Coal has the largest share of electricity generation.

The energy turnaround since 2011
• A shift away from nuclear energy and towards green energy. This
is the principle of German energy policy following the nuclear
disaster in Fukushima.
• In Germany, energy turnaround is the new buzzword for the
nuclear phase-out in politics and in the media. It is to be
facilitated by the development of renewable energy.
• The term energy turnaround has been around longer and it
actually refers to a complete transition to sustainable energy. Not
only nuclear, but also the fossil fuels (oil, coal, natural gas) should
be replaced by renewable energies (wind energy, hydropower,
solar energy, bio-energy and geo-thermal energy).

Garzweiler
• The lignite mine Garzweiler, is an open pit of RWE Power in the Rhenish
lignite mining area in North Rhine-Westphalia and was named after the
village in the municipality of Garzweiler Juechen.
Positive Side
 No nuclear energy is needed
Negative Side
 Co2 emission

Global Warming
Consequences of the
Climate Change
Extreme weather conditions
Extreme weather conditions
•
•
•
•
The winters are warmer
The summers are hotter
The weather conditions are very extreme
Climate Change was not very obvious in
Germany this year
• We had very bad weather, ice and snow in
May 2013. This is unusual and definitely does
not feel like global warming
Ozone Hole
Ozone Hole
• The ozone layer thins out and a hole above
the poles originates
• Reasons: mainly chlorine atoms
• This causes higher solar and ultra violet
radiation
• This is dangerous for all living beings
• From time to time the ozone hole gets bigger
Rising of the sea level
Rising of the sea level
• The sea level is rising 3.2 mm per year on
average
• Reason: glaciers melt because of warmer
temperatures
• The heating of the oceans leads to a thermal
expansion of the water
• The ice is melting → more water in the oceans
• Experts forecast a rise of sea levels of two or
three metres until 2100
Rising of the sea level in Germany
• The sea level is rising in Germany as well
• The North Sea and the Baltic Sea are predicted
to flood the north of the country
• One third of Germany will be flooded
Floods in Germany
• In June there were serious floods in Germany
Floods in Germany
• The German government pays 1.5 Billion €
and the Federal States pay 3.5 Billion € to
remove the damages
• There were also floods in 6 other countries
• At least 25 people died
Measures against floods
• Flooding areas are built to reduce the damage
• Several dykes are built
Dams
Flood
protection
Sandbags
Retention

Important measures to
ward off floods
Less sealed areas
Mobile barriers
