AC Generator (Alternator) :
DC Generator (Dynamo)
AC and DC
AC main source is socket
DC main from a battery or transformed from AC
AC more useful for simple products as the current switchs back and forth, bad for the circuitory
Used for more complex circuits

Nucleur (Cheat one)
Sunlight is one of our planet’s most abundant and freely available energy resources, with solar panesl we can capture this
Wind is a plentiful source of clean energy. Wind farms capture it with giant turbines
By building a dam or barrier, a large reservoir can be used to create a controlled flow of water that will drive a turbine, generating electricity.
Twice-daily tidal currents to drive turbine generators.
By harnessing the natural heat below the earth’s surface, geothermal energy can be used to heat homes directly or to generate electricity
Conversion of solid fuel made from plant materials into electricity
Splitting of the atom, releases energy and used to heat steam

Disadvantages
There are no fuel costs and no harmful polluting gases are produced.
Solar cells can provide electricity in remote locations where there is no mains electricity.
Solar cells are expensive and inefficient, so the cost of their electricity is high.
Solar cells do not work at night and not as well when it is cloudy.
Do not produce carbon dioxide or sulfur dioxide.
Very efficent
Wind farms are noisy and may spoil the view for people living near them.
Nuclear fuels are non-renewable energy resources. They will run out one day if we keep on using them, just will take a very long time.
f there is an accident, large amounts of radioactive material could be released into the environment
Wind is a renewable energy resource. There are no fuel costs and no harmful polluting gases are produced.
The amount of electricity generated depends on the strength of the wind. If there is no wind, there is no electricity.
There are no fuel costs and no harmful polluting gases are produced.
There are no fuel costs and no harmful polluting gases are produced.
Very reliable and can be easily switched on.

Tidal barrages destroy the habitats of estuary species, including wading birds.
Dams flood farmland and push people from their homes.
The rotting vegetation underwater releases methane, which is a greenhouse gas.
The rotting vegetation underwater releases methane, which is a greenhouse gas.
There are no fuel costs and no harmful polluting gases are produced.
The hot water and steam can be used to heat buildings directly.
Most parts of the world do not have suitable areas where geothermal energy can be exploited.
Advantages
Biofuels are made from many different sources such as manure, waste from crops and plants grown specifically for the fuel, sustainable
Carbon Neutral, absorb the carbon they release when burnt
Cost of Production is higher
Monoculture of these crops causes soil damage
Require lots of land
Hard to find suitable location
Expensive
Expensive to build
Looks ugly to tourists
High energy density
Predictable as it relies on the moon and sun
Easily adjust output
Safe
