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.

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
