POWER STATIONS

Untitled Slide

• Power stations convert energy sources into electricity.
• These use mostly turbines to drive energy!
• They are situated all round the globe.
• There are public and private power stations.

NUCLEAR POWER STATION

Untitled Slide

• Thermal power station which heat is used to generate steam
• The steam drives a steam turbine connected to a generate
• Then generater produces electricity.
• There are 439 stations in 31 countries as to the IAEA report

HDROELCTRIC

Untitled Slide

• Electricity is produced by use of gravity
• Gravitational force makes the water fall or flow
• This flowing water has high pressure
• The pressure drives the turbine for electricity
• Situated in 150 countries

GEOTHERMAL

Untitled Slide

• Use steam from reservoirs of hot water
• Found a few km or more below the earth's surface
• The steam rotates the turbine which produces electricity
• There are dry,flash,binary steams
• Produced in 24 countries while geothermal heating in 70 countries

WAVE

Untitled Slide

• Wave capture chamber set into rock face
• Tidal power pushes water into chambers
• Air oscillates water column
• Rushing of water drives the turbine
• 5 country's power station that run on wave power

WIND

Untitled Slide

• Wind pushes the turbine
• Turbine generates electricity
• 83 countries have wind power plants
• Chine is the leading in production followed by USA

Untitled Slide

TIDAL

Untitled Slide

• Hydropower that converts energy of tides
• Energy of tides into electricity
• Renewable energy
• First ever station used to grind wheat

Untitled Slide

SOLAR

Untitled Slide

• Conversion of sunlight directly into electricity
• Directly using photovoltaics
• Indirectly using concentrated solar power
• CSP uses lenses or mirrors to track sun
• Solar power is gained from solar panels
