Title: Generating Electricity


1
Generating Electricity World Electricity
Generation LG to compare different
methods of electricity generation
2
Generating Electricity Electricity Generation
electrical energy has to be made by conversion
from some other form of energy LG to
compare different methods of electricity
generation
3
Generating Electricity Electricity Generation
electrical energy has to be made by conversion
from some other form of energy e.g.
hydroelectric generation Turbine a fan-like
device which turns in response to the
pressure of falling water LG to compare
different methods of electricity generation
4
Generating Electricity Electricity Generation
electrical energy has to be made by conversion
from some other form of energy e.g.
hydroelectric generation Generator a coil of
wire turned inside a magnet generates
electricity LG to compare different
methods of electricity generation
5
Generating Electricity Electricity Generation
electrical energy has to be made by conversion
from some other form of energy e.g.
hydroelectric generation Power lines
electricity generated is carried in wires
over long distances to our homes LG to
compare different methods of electricity
generation
6
Generating Electricity Electricity Generation
electrical energy has to be made by conversion
from some other form of energy e.g. tidal
generation -high low tides occur twice
daily -tidal water movement can be used to
turn a turbine LG to compare different
methods of electricity generation
7
Generating Electricity LG to
compare different methods of electricity
generation
8
Generating Electricity Electricity Generation
electrical energy has to be made by conversion
from some other form of energy e.g. thermal
generation -water is heated to make
steam -pressure builds the steam can only
escape by passing through a turbine -this
turns the turbine LG to compare different
methods of electricity generation
9

generation
10
Generating Electricity Electricity Generation
electrical energy has to be made by conversion
from some other form of energy e.g. thermal
generation Fossil Fuel burning coal, oil, or
natural gas can be used to heat the
water LG to compare different methods
of electricity generation
11
Generating Electricity Electricity Generation
electrical energy has to be made by conversion
from some other form of energy e.g. thermal
generation Fossil Fuel burning coal, oil, or
natural gas can be used to heat the
water Radioactive Material when the nuclei of
uranium atoms break apart huge amounts of
energy is released, which can be used to heat
the water LG to compare different methods
of electricity generation
12
Generating Electricity Electricity Generation
electrical energy has to be made by conversion
from some other form of energy e.g. thermal
generation Fossil Fuel burning coal, oil, or
natural gas can be used to heat the
water Radioactive Material when the nuclei of
uranium atoms break apart huge amounts of
energy is released, which can be used to heat
the water Biomass biodegradable wastes can be
burned to heat the water LG to compare
different methods of electricity generation
13
Generating Electricity Electricity Generation
electrical energy has to be made by conversion
from some other form of energy e.g. Wind -the
blades themselves act as a turbine to turn the
middle of the generator to produce
electricity called wind turbines, not wind
mills wind turbine video LG to compare
different methods of electricity generation
14
Generating Electricity Electricity Generation
electrical energy has to be made by conversion
from some other form of energy e.g.
Light photovoltaic cells converts light
directly into electrical energy LG to
compare different methods of electricity
generation
