1 CAMBRIDGE INTERNATIONAL EXAMINATIONS International General Certificate of Secondary Education MARK SCHEME for the May/June 2013 series 0417 INFORMATION AND COMMUNICATION TECHNOLOGY 0417/21 Paper 2 (Practical Test A), maximum raw mark 80 This mark scheme is published as an aid to teachers and candidates, to indicate the requirements of the examination. It shows the basis on which Examiners were instructed to award marks. It does not indicate the details of the discussions that took place at an Examiners meeting before marking began, which would have considered the acceptability of alternative answers. Mark schemes should be read in conjunction with the question paper and the Principal Examiner Report for Teachers. Cambridge will not enter into discussions about these mark schemes. Cambridge is publishing the mark schemes for the May/June 2013 series for most IGCSE, GCE Advanced Level and Advanced Subsidiary Level components and some Ordinary Level components.

It is growing at the rate of 30% annually and is extensively used in Europe, Asia and the United States. the Atlantic Ocean, with some local opportunities in areas of the Mediterranean and Black Seas. The deep offshore potential is even larger but costs mean development is slow. Report by: Candidate Name Offshore Wind in the UK Subtitle Data entry 100% accurate, 18 pt sans-serif Italic, The bold, UK right has aligned the largest wind energy resource in Europe with an offshore wind potential equal to three times its electricity demand. Surrounded by a large shallow continental shelf with good access to available strong and constant offshore winds it is ideally placed to exploit the enormous potential for offshore wind power and offshore wind farm development. The sea is relatively shallow around the land masses allowing for turbine foundations to be driven into the seabed rather than attempting to accomplish a complicated floating system of turbines. To date, 9 offshore wind farms have been built around the UK coastline with 330 offshore turbines, equating to MW of installed capacity. The UK has a target of securing 15% of all its energy needs for electricity, heat and transport from renewable sources From an emerging fuel source twenty years ago, wind energy has transformed Footer by Offshore wind farms in the UK Date left, Name & Cand Number into a mature and booming global producing right 190 mark Body text MW or more of power are: business.

Europe s offshore wind potential is huge with the technical potential of offshore wind being six to seven times greater than projected electricity demand. At the end of 2010 there were 1,136 offshore wind turbines installed and connected to the grid on 45 wind farms in 9 countries with an operating capacity of 2,396 MW. The 9 European countries with offshore wind power capacity in 2010 were: Offshore wind power in Europe Country Capacity (MW) UK 1341 Denmark 854 Netherlands 249 Belgium 195 Sweden 164 Germany 92 Finland 26 Ireland 25 Norway 2.3 Largest Offshore Operations but via undersea cables.

Over the past 10 years global wind power capacity has continued to grow at an Benefits of Offshore Offshore wind farms are generally larger average cumulative rate of over 30%. Improvements in wind energy technology than onshore farms and the electricity is mean that generation costs have transported not underground or overhead, dramatically decreased and modern wind turbines have better power ratings,

It is estimated that 40,000 wind turbines will be installed in the next 10 years. The European Union has set ambitious targets to provide 20% of Europe s energy from renewable sources by As a proven source of clean, affordable energy, wind resources have a vital role to play in realising these goals. Conventional fuels have a dangerous impact on the climate and the drive for a future of cleaner, more sustainable energy technologies means wind power will go from strength to strength.
