Title: 2050 Domestic lighting, appliances, and cooking costs Content: h1 Issues / to do * I think I've misinterpreted £m/PJ/a in converting it to £/TWh * Appliances haven't been costed * Methodology is inconsistent with 2050 Commercial lighting, appliances, and catering costs h1 data sources Markal3.24Doc, note just one cost - no high/low h1 Methodology Cooking - Use Markal assumption of one cooker per household. Assume scrappage after 15 years (MARKAL assumes 14), therefore 1/3rd of all stock needs replacing. New stock is therefore the difference between the implied split of electric/gas by that year (assume same efficiency of gas and electric hobs and cookers e.g. 50% fuel used from gas for cooking = 50% gas hobs and cookers in homes) and stock scrapped. Lighting - Use MARKAL assumption of split between household electricity demand where 16% is lighting as the costed element and hold up to 2050. Cost the level 1 as using standard lighting (from MARKAL costs) and every additional reduction has a low cost of zero (it could be met through behavioural change) and high cost is that every additional TWh reduction from level 1 is met by the most expensive lighting technology. h1 Differences with MARKAL Markal constrains electric hobs to 70% of cooking fuel use. h1 Issues # No range # Assumption of fuel split = appliance split in homes may not hold # Haven't costed lighting and appliances yet User: Tom Counsell Picture updated at: Signed off by: Signed off at: |
