Animations

	Energy - let's save it! An animation by the European Commission.
	Better light with less energy An animation by the European Commission.
	Energy action This animation shows a few ways to help save energy. Switch to low energy light bulbs. They use one fifth of the energy of traditional bulbs. Remember to switch off your TV at the wall. Standby leaks electricity. As you will see, there are also easy ways to save energy with kettles, washing machines and windows. But first switch off the light...
	Climate change Over millions of years, prehistoric forests grew on the earth. They absorbed carbon dioxide from the air. The trees died and heat and pressure turned them into coal, oil and gas. When we burn these fuels, carbon dioxide is rapidly released. This is changing our climate.
	Energy from water The sun heats water in the sea. The water rises and falls as rain. Dams trap the water in lakes at the top of hills. The water travels fast down long pipes and spins big turbines to make electricity.
	Ground source heat pump Heat in the ground warms tubes full of liquid (similar to car antifreeze). This warmth is used to heat vapour, which is compressed to greatly increase its temperature. The vapour is condensed and the heat is passed to radiators or hot water for washing. Electricity is used, but the efficiency of the system is 220-300 %. So much more heat is generated.
	Heat and hot water from the sun Black tubes are put on roofs. The tubes are full of special liquid (similar to car antifreeze). They trap heat from the sun. The heat is passed into water pipes and can be used for showers or washing clothes.
	Electricity from the sun This animation shows how energy from the sun can be turned into electricity. This is done by special materials called photovoltaics. These are used to make solar panels.
	Heat and hot water from trees Willow trees grow using carbon dioxide, water and sunlight. After 4 years they can be dried and burned to produce heat and hot water for buildings. So you don't have to use oil, coal or gas. Other trees, wood waste and straw can also be used for bioenergy - even in large power stations.
	Sustainable Transport Cars, lorries, buses and planes all use fossil fuels. These produce a gas called carbon dioxide.The gas collects above the earth. It traps heat (like a greenhouse) and makes the planet get hotter. Ride a bike, walk or take a bus. You will reduce greenhouse gases and help slow down global warming.
	Wind Energy This animation shows how wind energy can be used to generate electricity.The wind turns the rotor blades of the turbine. These are connected to gears that make a generator spin at high speed. The generator produces electricty that is sent to houses through pylons.
	Carbon dioxide Capture and Storage CCS For the next few years, power stations will use oil, gas and coal to make energy. But this produces the carbon dioxide gas that causes climate change. One answer is to capture the gas and store it deep underground in porous rock (rock with tiny holes in it). Then the power station only produces water, air and sometimes hydrogen gas. Hydrogen can be used as a fuel in vehicles or future power stations. CCS is a new idea that is being tested.
	Advanced biofuels Scientists are developing new ways to make biofuels from trees, energy plants, waste materials, straw and even algae (tiny green plants that grow in ponds and the sea). It takes time and money, but the fuels of the future could soon be used by lorries, ships and planes for long journeys. For short journeys in cities, smaller electric vehicles may be the best way to travel.
