Energy Resources And Energy Generation Flashcards
Renewable
It replenishes at a faster rate than it is used, it doesn’t run out.
Non-renewable
It is used at a faster rate than it is replenished, hence it will run out.
Advantages of coal power
- consistent
- available
- lots of power stations
Disadvantages of coal power
- pollution
- high maintenance
Transfer of coal power
Chemical energy (stored in the fuel) -Transferred by Heating-> Thermal energy (stored in the water) -Transferred by Heating-> Kinetic energy (stored in the steam) -Transferred Mechanically-Kinetic Energy (in the turbines and generator) -Transferred Electrically-> Houses (in the cables)
Advantages of Solar Cells
- good on short-scale
- cheap
Disadvantages of Solar Cells
- weather-dependent
- uncontrollable
- inefficient
Transfer of Solar Cells
Transferred by Radiation (from the Sun) -> Transferred Electrically (in the cables)
Advantages of wind power
- reliable
- renewable
- job creation
- scalability
Disadvantages of wind power
- damages environment (migrating birds)
- too much energy
- unattractive (disturbs landscape)
Transfer of wind power
Kinetic energy (in the wind) -Transferred Mechanically-> Kinetic Energy (in the turbines and generator) -Transferred Electrically-> Houses (in the cables)
Advantages of Hydroelectric Power
- renewable
- can be controlled
- turned up and down
- consistent
Disadvantages of Hydroelectric Power
- flooding
- too much energy
- high maintenance
- harm sea-life
- restricted to areas
- very loud
- affected by climate
Transfer of Hydroelectric Power
Gravitational Potential Energy (stored in the water) -(Transferred mechanically)-> Kinetic Energy (in the water) -Transferred Mechanically-Kinetic Energy (in the turbines and generator) -> Transferred Electrically-> Houses (in the cables)
Advantages of tidal power
- renewable
- high energy production
- reliable
Disadvantages of tidal power
- too much energy
- dangerous if broken

Advantages of Geothermal Power
- lots of electricity
- renewable
- reliable
- low maintenance
Disadvantages of Geothermal Power
- greenhouse gas or toxic emissions
- high upfront cost
Transfer of Geothermal Power
Thermal energy (in the ground) -Transferred by Heating-> Thermal energy (in the water) -Transferred Mechanically-> Kinetic Energy (in the steam) -Transferred Mechanically-> Kinetic Energy (in the turbines and generator) -Transferred Electrically-> Houses (in the cables)
Advantages of biomass
- more renewable than fossil fuels
- low maintenance
Disadvantages of Biomass
- greenhouse gases
- large growth area
- less efficient
Transfers of Biomass
Chemical Energy (stored in biomass) -Transferred by Heating-> Thermal Energy (in the water) -Transferred Mechanically-> Kinetic Energy (in the steam) -Transferred Mechanically-> Kinetic Energy (in the turbines and generator) -Transferred Electrically-> Houses (in the cables)
Nuclear fission
Splitting atoms to release energy
Advantages of Nuclear Power
- produces a lot of energy
- only need a little uranium
- lasts long
- low risk
Disadvantages of Nuclear Power
- radioactive
- high maintenance
- non-renewable
- large (needs lots of space)
- hard to find building space
- high consequence
Transfers of Nuclear Power
Nuclear energy (stored in the fuel) -Transferred by Heating-> Thermal Energy (in the water) -Transferred Mechanically-> Kinetic Energy (in the steam) -Transferred Mechanically-> Kinetic Energy (in the turbines and generator) -Transferred Electrically-> Houses (in the cables)
