Resource summary
P2: Sustainable Energy
Energy Stores and Transfers
Energy is Transferred Between Stores
Thermal
Kinetic
Gravitational Potential
Elastic
Chemical
Nuclear
Electromagnetic
Electrostatic
Energy can be Transferred by Heating
Conduction
The vibrating particles transfer energy to close particles.
Convection
The energetic particles move away from hotter to cooler regions.
Conservation of Energy and power
Energy can be transferred and stored but NOT created or destroyed
Energy Transferred Equation
Energy Transferred (J) = Power (W) x Time (s)
Efficiency and Sankey Diagrams
Efficiency Equation
Efficiency = Useful Energy Transferred / Total Energy Transferred
Use the Diagram to Show Efficiency
Energy Resources
Renewable
Never run out
Most do damage to the environment, but less than non-renewable
Don't provide as much energy
Main resources: wind, sun & tides
Non-Renewable
Will run out one day
Reliable
Damages the environment a lot.
Nuclear waste releases radiation, makes it dangerous
Main resources: fossil & nuclear fuels
The National Grid
Plugs Contain 3 Wires
Live Wire - Carries the voltage.
Neutral Wire - Completes the circuit - electricity flows in through the live wire and out through the neutral.
Earth Wire - For safety - Carries the current away if something goes wrong.
