Energy of the world Flashcards
Controlled nuclear fission
Can be used to produce near limitless amounts of heat
No greenhouse gases produced
Non-renewable energy
Controlled nuclear fission
Fossil fuels
Problems with nuclear fission
Problems with storing the radioactive waste over long periods of time
Fossil fuels
Oil, gas and coal
Problems with fossil fuels
Non-renewable
Produce greenhouse gases
Renewable energy
Tidal power Wind power Solar power Geothermal energy Solar heating Hydroelectricity
Tidal power
Barriers across tidal estuaries drive water turbines as the tide comes in
Wind power
The winds movement turns wind turbines thus making energy that can be used as electricity
Solar power
Photovoltaic cells are used to convert the suns energy into electricity
Geothermal energy
Naturally occurring energy produced by the earth’s core
Solar heating
By focusing mirrors
Water can be heated for high pressure steam production
Hydroelectricity
Potential energy in the river to kinetic energy in a turbine, turns a generator to power electricity
work measured in
Joules
Work is
Transferring energy
