Pros and cons of renewable energies+ -
endless Conditions and locations huge impact
No burning of fossil fuels no toxic chemicals
Investment costs are high
Widely available drawbacks, or limitations with respect to environment and ecology
low maintenance costs associated with them
Not yet a global acceptance
Kinds of sustainable/ renewable energy
WATER

Waterenergy
Potential energy Kinetic energy electric energy
Hydroelectric station
Pumped storage hydroelectric station
Geothermal energy
Heat energy electric energy
the drilling can cause an earthquakeyou might drill a hole without finding a heat
sourceyou could hit the groundwater testing for places with enough heat is very
expensive
Risks of geothermal energy
Solar energyHeat energy electric energy

chemical energy thermal energy electric energy
Sustainability of renewable energy forms
Solar radiation energy
• Solar energy is up to 50 times more
sustainable in comparison to coal
• the solar panels must be produced
before they can be placed on the roof
Production
• Mining of silicium• Silicium gets raffined
takes a lot of hydrochloric acid• Wafer gets formed• Wafer goes into bath of
industrial acids and heavy metals to become a useful solar cell.
• the poisonous production processes endanger the environment and must be replaced by an other, responsible way.
• Health of local population and workers must be guaranteed
• BUT:• Responsible choises are expensive• Hard global competition• Economization is necessary
LOCATIONS FOR RENEWABLE ENERGIESSolar Energy Panels
- Solar Heat Panels- Solar Electricity
Wind Energy Parks
Water Energy Locations- River Power Plant- Reservoir Power
Station
Geothermal Energy Plants
next to the equator
coastal regions; high plateaus
-> rivers; barrier lakes (ex. the Alps)
-> in the best case Island; Greece; Turkey
LOKATIONS FOR RENEWABLE ENERGIESSolar electricity panels
Solar heat panels Next to the equator
Wind energy parks Coastal regionsHigh altitude plateaus
Water energy:-River power plants- Reservoir power stations
Rivers and barrier lakes in mountain regions
Geothermal power plants Iceland, Greece, Turkey
