Energy

The main stores of energy are:
k

el
m

Energy can be transferred by:
H
M
W
E

When energy is , some energy is . This to the environment.

For example, leads to the transfer of energy into a thermal store. This heat then dissipates.

Unwanted energy transfers can be reduced by:

Thermal
Walls in homes

An energy resource is used to and other useful forms of energy.

Energy resource rotates a
->
This rotates a in a magnetic field (a )
->
This produces an electric current: an energy .

Fossil Fuels are burnt to heat a fluid, producing and turning a turbine.

In volcanic places, magma has lots of energy. The magma heats , which heats water in pipes. This rotates a turbine and is known as energy.

Holding water above the ground is a store of potential energy. Allowing it to fall rotates a turbine. This is known as power.

Waves and tides are stores of energy. They can rotate turbines.

In a nuclear reactor, the energy stored in the of atoms is released as energy. Some of this heats up which then heats up a fluid. This creates steam and rotates a turbine.

Solar Cells absorb the waves from the . Some create an current without a generator, while some use the heat from the Sun to boil water, create and rotate a turbine.

The Sun is the original source of energy for:
F fuels
