11 Introduction to Energy Energy is stored work Energy is the ability to get work done Energy ist necessary to get things moved, heated up etc. Energy can be gathered from different sources: coal, crude oil, uranium Energy can be dissipated/converted into usable forms of energy like heat, light etc.

12 Units of Energy For example: flap of a fly = 1 Joule (FOTOFliege) burning match = 1000 Joule (FOTO) Motor of a car = 300 MJ per hour = 0,3 Billion Joule 1 Joule = 1 Ws 1 kwh = 1000 Ws = 3600 kj 1 ton of hard coal = 8141 kwh = 30 GJ = 1 Billion Joule

13 How to gain usable energy? Fossil fuels: out of coal, crude oil, natural gas, nuclear fuel, thermonuclear fusion Regenerative/renewable energy: solar energy/solar power, wind power, tidal power, water power, geothermal energy, biomass energy, Hydrogen

14 Differentiation between Primary energy Secondary energy Effective/usefull energy For example: crude oil heating oil/fuel oil heating or: Uranium ore current/electricity light

15 Energy cycle efficiency Primary energy (natural gas, black coal, uranium) = 100 % in a normal power plant convertion-loss 62% propagation loss 2% energy recovery for electricity 36% Primary energy (natural gas) = 100 % in a small combined heat and power station convertion-loss 10% propagation loss <0,1% energy recovery for electricity 30% and heating 60%

16 General aspects on automotive motion

17 How to move a car? Three types of motors electric motor combustion motor rocket propulsion ;)

18 How to keep a car running with electricity? stored in accumulator batteries - electricity is gained from solar energy, wind power, tide power, heat pump, digester gas plant, fermentation gas plant, (planned: thermonuclear fusion) etc. atomic energy (in submarines) solar cells hydrogen fuel cell

19 Electric Motors have no local emission! Electric motors are (at the moment) not relevant for moving cars Because of the short cruising range the long time to refuel The low maximum speed with current accumulator batteries
