The windiest places in the UK are the tops of hills and ridges in Scotland and the West of Ireland, and in the open sea. There are over 2,000 wind turbines in the UK at the moment. The government wants to 6,000 more onshore and 4,000 more offshore turbines installed by 2020. Many people object to the use of wind turbines because of their impact. Linda please insert photo or clip art of a wind turbine First of all Caitlin interviews local people. List 3 arguments for and against the wind farm that Caitlin might hear. Caitlin writes up all the different views but now needs to write a paragraph to finish off her report. Write a paragraph for Caitlin that weighs up both sides of the argument. You should make sure that you use ideas about the availability of energy and the possible impact on the environment of the wind farm compared with any alternatives. Caitlin works for her local newspaper. Her boss has asked her to write a balanced report about the new wind farm that is due to be built near by.

2. Teachers’ guide Goal The problem targets understanding part of the Big Idea: Energy Resources Fossil fuels are concentrated stores of energy but they are non- renewable. Renewable energy is derived from a natural resource, where the energy is constantly replaced, but they are more dilute stores of energy, and their output can vary. - Not sure what to put here- lots is crossed out on the Wiki?

As above but also considers the relative impact of the wind farm on the environment e.g. considers the local impact (such as unsightly building in the countryside) but then also considers the wider consequences e.g. reducing the need elsewhere to generate electricity using fossil fuels and thereby reducing the emission of greenhouse gases

For each of the possible future events predict how it might our use of renewable energy resources. Give reasons for your answers including the availability of the energy resources in question and the environmental impact of your choice. Linda – photo to illustrate a conference please A World Climate Change Conference agrees limits to carbon emissions well below our country’s plans. Linda – a photo of an oil rig surrounded by sea please A new source of gas is found in the North Sea. Linda- a photo of Antarctica please Oil is discovered under Antarctica. Linda- photo of oil tanker please Crude oil supplies worldwide are very low. Those countries with their own supplies stop exporting to other countries. If we decide to increase the amount of electricity produced without burning fossil fuels in each area of the country will need to contribute to generating the electricity. Look at the map showing the area around the Severn Estuary and Bristol Channel. Write a brief proposal on what types of non fossil fuel based energy resources this part of the country could contribute. You may wish to use powerpoint to do this. You should include: Slide 1- suggesting at least two non fossil fuel energy resources suitable for this part of the UK (in order of preference) Slide 2- reasons for each including cost and efficiency of the energy transfers involved Slide 3- any possible arguments against the proposals Slide 4 – arguments for the proposals Linda The link below should take you to the area of map this needs. Please draw and add in : The motorways. Labels for Cardiff, Bristol, Minehead, Weston Supermare Nuclear power station on coast half way between Watchet and Burnham on Sea Label the River Severn on the narrow bit of the river and Bristol Channel on the wide bit. http://maps.google.co.uk/maps?hl=en&ie=UTF8&ll=51.412912,- 3.548584&spn=1.139169,2.158813&z=9

Nviz Energy Resources Problems 5-7 Activity from the Live & Kicking unit © upd8 wikid, built by cracking science 2009 This page may have been changed from the original Marking guide Emerald 2a - suggests how our use of renewable energies is likely to change in the future makes sensible suggestions for future energy supplies based on suggested future circumstances e.g carbon limits- wind, wave or tidal (but not burning of refuse),new sources of gas- possibly build another gas fire power station etc. [There is no objective for Solve problems at emerald level. Looks a bit odd leaving this blank. Currently the level 5 statements are included in sapphire.] Sapphire 2b - predicts how our use of renewable energies might change in the future as a result of world events makes predictions by consideration of potential consequences e.g. recognises that even if more gas was found a way would need to be developed to burn the gas without raising carbon dioxide levels further 3a- recommends specific energy resources for a site, based on the availability of energy, and cost makes sensible suggestions as to suitable means of electricity generation on the geographical area shown e.g. Tidal and expansion of nuclear or development of wind farms. justifies these choices in terms of the natural resources available or pre existing facilities and gives some order of preference in terms of the electricity generation that the geographical area shown could provide taking in to account factors such as cost, availability or environmental considerations. Diamond 2c – as above but gives reasons based on the availability and environmental impact of renewables takes into account the availability and environmental impact of the different energy options e.g. With restricted oil supply, still recognises the limits in availability of renewable energy without substantial investment and development, and potential environmental concerns e.g. damage of estuary habitat with a tidal barrage, affect of wind turbines on the landscape etc. and/or 3b as above but also considers the energy efficiency of the energy transfers involved. shows understanding that each wind turbine only transfers a limited amount of kinetic energy into electrical energy and therefore a very large number of turbines are needed to replace fossil fuel power stations and/or links the large Tides of the area with the potential to transfer a large amount of kinetic energy into electrical in comparison with other areas of the country and uses this as an argument as to why a facility to use this tidal energy may need to be built in this location and/or
