13 Change in Fuel Mix for Electricity Generation in UK Major changes in the Fuel Mix for Electricity Generation
14 From 1990 to 1999 Substantial fall in carbon dioxide emissions Despite 23% increase in demand However, once change is made saving cannot be made again Hence rise in recent years Carbon Emission Factors for Electricity Generation Coal ~ 1000 g/kWh Oil ~ 850 g/kWh Gas ~ 540 g/kWh Gas (CCGT) ~ 420 g/kWh Nuclear ~ 4 g/kWh Electricity Options for the Future
15 Historic and Future Demand for Electricity Number of households will rise by 17.5% by 2025 and consumption per household must fall by this amount just to remain static Business as usual Energy Efficient Future
16 The Gas Scenario Assumes all new non-renewable generation is from gas. Replacements for ageing plant Additions to deal with demand changes Assumes 10.4% renewables by % renewables by 2020 Energy Efficiency – consumption capped at 420 TWh by 2010 But 68% growth in gas demand (compared to 2002) Business as Usual 257% increase in gas consumption ( compared to 2002) Electricity Options for the Future
17 Energy Efficiency Scenario Other Options New Nuclear needed by 2025 if CO 2 are to fall significantly Business as Usual Scenario New Nuclear is required even to reduce back to 1990 levels 25% Renewables by MW Wind MW Other Renewables inc. Tidal, hydro, biomass etc. Alternative Electricity Options for the Future
18 Energy Saving: Why is it important for the UK? In the past the UK has been self sufficient in energy Under present trends the UK will be a substantive importer of natural gas ~ 80% and oil by 2020 It makes sense to reduce energy demand and still remain competitive economically. Reducing energy demand will also see a reduction in carbon dioxide - the main contributor to Global Warming The Government has set targets and provided mechanisms to provide grants for individuals and industry. However, more could be done.
19 Government Targets 10.4% of total electricity by 2010 unlikely to be met - at best 6 - 7% 20% by 2020 Promoting Renewables in the UK Electricity Market Onshore 1.5 MW turbine 60 MW offshore Wind Farm at Yarmouth commissioned early New Wave Powered device - launched 6th August 2004
20 Renewables Obligation –Requires all suppliers to provide a minimum percentage of electricity from New Renewables. –In the percentage will be 6.7%, but only around 4% is being achieved. Target is increased each year –In 2006 – 2007 Suppliers will fined at p per kWh (1.662 Roubles) per kWh for any shortfall. Fine is index linked – in 2002 – 3 it was 3.0 p per kWh –This is introducing a new market in the trading of Renewable Obligation Certificates - issued as proof of generation. Promoting Renewables in the UK Electricity Market
21 The Regulator OFGEM SUPPLIERS Trader and Brokers Renewable Generator Notifies Regulator how much generated. ROC’s issued Sells ROCs to Trader Sells Electricity with or without ROCs Notifies OFGEM of compliance - i.e. ROCs or pays FINE Buys ROCs from Trader FINES recycled in proportion to ROCs held Renewable Obligation Certificates (ROCs)

24 Started in Norwich Now also in Suffolk, Camden, Essex, Cheshire and others Elsewhere in World: –USA (North Carolina), Japan (Okinawa) China (Shanghai) The Carbon Reduction Project Aims to Reduce CO 2 emissions by 60% to combat Climate Change Promoting Approriate Renewable Energy and Energy Conservation Promoting Awareness Working with businesses, Public Bodies, individuals
25 Understandable Language Energy Saving: Awareness / Education / Advice A mobile phone charger left on up to 25 kg CO 2 a year Standby on television > 60 kg per year Filling up with petrol (~£35 for a full tank) kg of CO 2 (5% of a balloon) A tumble dryer uses four times as much energy as the equivalent washing machine - use the dryer sparingly Boiling an extra cup full of water causes the emission of 25 cupfuls of carbon dioxide. and the domestic sector Each person in UK emits 9 tonnes of CO 2 per year ~ 5 hot air balloons Russia 10.5 tonnes ~ 6 balloons
Community Engagement - Reepham Total emitted by residents of Reepham tonnes of CO 2 = 7382 hot air balloons of CO 2 Reepham is now developing a zero-carbon ambition in the Community Flying 11% Heating/ hot water 40% Other household energy 28% Car 21% CO 2 by proportion

37 And Finally Lao Tzu ( BC) Chinese Artist and Taoist philosopher "If you do not change direction, you may end up where you are heading." If we do not change direction then we WILL end up where we are heading and the adverse consequences of Climate Change. Combating Climate Change requires Promotion of Appropriate Renewable Energy, Energy Conservation Carbon Capture and Sequestration in the Future Promoting Awareness to use energy more effectively Supporting the aims of the Programme VISIT the WEB Site This presentation will be displayed on above WEB Site >> follow Academic Links Keith Tovey Н.К.Тови

39 Energy Saving: The UK Perspective UK has become more efficient in using energy to generate wealth over past 50 years. Generates the same wealth with 45% of energy as in Improvement ~ 1.45% per annum
40 Energy Consumption: The UK Perspective Wealth of UK increased uniformly with energy in 1950s and 1960s Major infra-structure projects in late 1960s - early 1970s restructuring followed by increase efficiency increased conservation
