Energy Resources Oliver Headlam-Morley

Non-Renewable Energy Resources  These are forms of energy that can not be used again and mainly come from fossil fuels  Fossil fuels include Coal, Natural Gas, Oil and Nuclear power.  The problems with fossil fuels is that when burnt they are very damaging to the Earth

Amount’s of energy produced

Nuclear Energy How Does it Work? The reactor splits atoms. This releases huge amounts of energy and heat. This then heats up water to massive temperatures. water is then turned into steam which turns a turbine and creates a lot of power

Nuclear Energy Cont… Advantages  It does not emit any emissions  It produces a lot of energy  It does not harm the environment Disadvantages  It produces nuclear waste  It isn't renewable  Nuclear waste is very DANGEROUS and hard to store

Coal, Natural Gas and Oil

Coal, Natural Gas and Oil Cont…  All theses power stations work in basically the same way the only difference being the fuel.  They all burn their fuel and use the resulted energy to heat water.  The water turns into steam which turns in a turbine thus creating power

Renewable Energy Resources  Renewable energy means that it will never run out and is a reliable supply of energy  It does not harm the environment in any way whatsoever by releasing emissions  At the moment they are not as effective as fossil fuel powered stations

Wind Power  The wind turns the rotor blades which in turn, turn the turbine.  They aren't very efficient as they require the wind to work and the wind isn't always blowing.  However the wind turbine doesn't harm the environment as their will always be wind some where

Solar Power  This diagram shows water being heated by the suns rays.  Other materials like silicon produce an electric current when hit by the suns light

Wave Power  This works very simple as it works by using the motion of the waves to generate power  As the waves hit the generator it moves up and down this motion drives a generator which creates power

Hydroelectric Power

Hydroelectric Power cont..  Water from the reservoir falls down pipes and turns turbines  The turbines turn generators which create the power  An example of an hydroelectric dam is the hover dam in America

Tidal Power  The turbines are turned by tidal currents  They are heavily geared so that the slow turning blades produce larger amounts of energy  The power station does not harm any wildlife or the environment  This means their power output is always predictable with the tides

Geothermal Power  Cold water is pumped down into the earth  It is turned into steam and is pushed back up the other pipe  This steam drives the turbine which creates the electricity
