WAVE ENERGY           //How it works: // //Example: // Pelamis Machine Wave Energy Converter //The energy changes invovled: // Waves: As long as the waves propagate slower than the wind speed just above the waves, there is an energy transfer from the wind to the waves. Pelamis Machine Wave Energy Converter  The rolling motion of the waves is resisted by hydraulics, which pump oil through a hydrolic motor. This motor is what converts the wave motion to electricity by powering electrical generators. Fact& Figures > //Environmental Effects // - Waves energy are //__environmentally friendly__// - do not do any harm to it   - - //__Reduce carbon emissions of greenhouse gases__// - less contribution to global warming
 * 1) Waves are caused by the //__wind__// blowing over the surface of the ocean.
 * 2) The wind blows with enough __//consistency//__ and //__force__// to provide continuous waves.
 * 3) <span style="font-family: 'Arial Black',Gadget,sans-serif;">Wave energy is produced when //__electricity generators__// are placed on the surface of the ocean.
 * 4) <span style="font-family: 'Arial Black',Gadget,sans-serif;">The energy provided is most often used in water pumps.
 * 5) <span style="font-family: 'Arial Black',Gadget,sans-serif;">The output is determined by //__wave height, wave speed, wavelength, and water density.__//
 * <span style="font-family: 'Arial Black',Gadget,sans-serif;">A technology that uses the motion of __//ocean surface waves//__ to create //__electricity.__//
 * <span style="font-family: 'Arial Black',Gadget,sans-serif;">The machine is made up of //__connected sections__// which flex and bend as waves pass (motion which is used to generate electricity.)
 * <span style="font-family: 'Arial Black',Gadget,sans-serif;">Developed by the Scottish company Pelamis Waves Power.
 * <span style="font-family: 'Arial Black',Gadget,sans-serif;">the first wave farm consisting of three Pelamis machines was located at the coast of Portugal.
 * <span style="font-family: 'Arial Black',Gadget,sans-serif;">Generated by wind passing over the surface of the sea.
 * <span style="font-family: 'Arial Black',Gadget,sans-serif;">Technically and economically recoverable resource has been estimated to be 50-90TWh <span style="font-family: Arial,Helvetica,sans-serif;">(TeraWatt Hour) <span style="font-family: 'Arial Black',Gadget,sans-serif;"> of electricity per year, or 15-25% of current UK demand.
 * <span style="display: block; font-family: 'Arial Black',Gadget,sans-serif; text-align: left;">Wave is created: the //__progressive transfer of energy__// from the //__wind__// as it blows over the surface of the water.
 * <span style="display: block; font-family: 'Arial Black',Gadget,sans-serif; text-align: left;">Wave energy could play a major part in the world’s efforts to combat climate change, potentially displacing //__1 – 2 billion tonnes of CO2__// per annum from conventional fossil fuel.
 * <span style="font-family: 'Arial Black',Gadget,sans-serif;">Off the west coast of Ireland, the annual average wave height is 2.5m-3m, however winter events are substantially greater.
 * <span style="background-color: #000000; color: #f52121; font-family: 'Arial Black',Gadget,sans-serif; font-size: 120%;">Advantages || <span style="background-color: #100202; color: #f52121; font-family: 'Arial Black',Gadget,sans-serif; font-size: 120%;">Disadvantages  ||
 * <span style="font-family: 'Arial Black',Gadget,sans-serif;">- Reduce consumption of limited resources. || <span style="font-family: 'Arial Black',Gadget,sans-serif;">- May interfere with mooring and fishing ||
 * <span style="font-family: 'Arial Black',Gadget,sans-serif;">- Constructions would provide many employment opportunities || <span style="font-family: 'Arial Black',Gadget,sans-serif;">- Waves can be big or small so you may not always be able to generate electricity. ||
 * <span style="font-family: 'Arial Black',Gadget,sans-serif;">- Security of supply – renewable; never runs out || <span style="font-family: 'Arial Black',Gadget,sans-serif;">- Find a way of transporting the electricity from the sea onto the land - inefficient ||
 * <span style="font-family: 'Arial Black',Gadget,sans-serif;">- Fuel is not needed so the cost would reduce || <span style="font-family: 'Arial Black',Gadget,sans-serif;">- The equipment might cost a lot ||
