- Energy generation and storage
- How power is generated
- Non-renewable
- Formed in the carboniferous period. Dead organisms and plants sank to the bottom of swamps and decomposed under layers of sand clay and other minerals
- Coal = trees and plants + heat& pressure
- Oil= small animals (e.g plankton) + pressure= decomposition
- Natural gasses= small animals (plankton)+ pressure and heat
- Formed in the carboniferous period. Dead organisms and plants sank to the bottom of swamps and decomposed under layers of sand clay and other minerals
- Nuclear energy
- Energy stored in the nucleus of an atom
- Fission
- The splitting of a nucleus (uranium 235) into two smaller nuclei producing 2-3 neutrons and energy
- Fusion
- The joining of two small nuclei to make one big /larger nucleus lots of energy is produces.
- ATM only happends in the heart of a star (the sun)
- Non-renewable
- renewable energy
- wind
- airs motion becomes mechanical energy via a turbine connected to an electromagnetic generator
- solar
- passive
- No moving parts capture and use the suns raise e.g green house.
- active
- Mechanical components like fans or pumps to circulate heat carrying fluids.
- residential or commercial heating
- CSP= mirrors concintrate the suns rays on one point steam produced so turbine is reated generator produces electricity
- passive
- Hydro power
- Tidal power
- creates energy from the natural rise and fall of the tides
- tidal barrages, tidal fences and tidal turbines.
- Predictable energy source
- turbine+ generators
- dams and run of river
- Tidal power
- wind
- Energy storage systems including batteries
- Methods of storing electricity need for energy storage systems= higher need for energy for demand
