Coal fired Drax, our biggest station is rated at 4GW. At 68% load factor it produces 24TWhr of electricity consuming 10M tonnes of coal and producing about 30M tonnes of CO2.
To replace this one power station with photovoltaic generation at 10% load factor would require about 140M of Sanyo's best 200W panels, about 7 panels for every house in the county.
250kW inland wind turbines at 30% load factor would require over 45,000 such turbines.
Large offshore wind turbines at 3MW and operating at 40% load factor would require 2,280 such turbines.
One curiosity on the chart. It colour codes the fuel for each power station and lists coal, gas, oil, hydro, nuclear and wind and also lists steam as a fuel. It shows one of the latter in Brighton but I don't think there is a power station in Brighton. The nearest I know of is at Shoreham
where there is a new combined cycle gas fired system which replaced the old coal fired unit.
Anyone any idea what a steam powered generator could mean in this context?
I think steam refers to power generated from hot industrial processes where waste heat is used to raise steam and generated electricity. Such electricity is used on site with surplus sold.
