That's a Lorra Lorra Steel and Concrete to Boil 186 Kettles!


'Gold-Standard' data for wind energy comes from this site:  Renewables UK  The 'Onshore' + 'Offshore' Capacity is 12,119 MW. From the 29,534,391 MWh of 'Energy Produced', the average generational power works out at 3,369 MW, giving a Capacity Factor of 27.8%.

Page 16 of this site:  State of the Industry Report 2014 - Deployment  states: "...A snapshot of the UK wind industry taken on 30 June 2014 is shown in Table 1...". Page 15 shows 'Wind Energy Performance Totals'  - 'UK-wide Operating' as 11,183 MW.

It is very reasonable to apply the 27.8% Capacity Factor to this 'Total' to give generational power of 3,109 MW, working out at 27,252,389 MWh (27.252 TWh) of 'Energy Produced'.

From this:  Renewables UK  there are a total of 6,036 Onshore and Offshore turbines, meaning each one has a 2 MW capacity to give the 12,119 MW figure. So, the 30 June 11,183 MW means 5,591 x 2 MW turbines.

 5,591 wind turbines  generate 3,109 MW - so - 
   
each one is generating 556.07 kW

That's enough to boil 186 Kettles!



It is indeed

A LOT OF STEEL AND CONCRETE 


FOR A FEW CUPS OF TEA !

  2. We need to use less energy. We can do so. Your assumptions in the header are wrong.

  3. Yes, your right. I calculated that figure quite a few years ago when the mantra was ¼ of the worlds population uses ¾ of the energy.

    Data required for a recalculation is taken from this website: http://www.economicshelp.org/blog/5988/economics/list-of-countries-energy-use-per-capita/

    In 2012, with the population at 7 billion, World Average per capita (69) = 1790.1 kgoe; France (27) = 3958.8; Germany (29) = 3889.1; UK (41) = 3183.3

    In 2050, when population will be 10 billion, if we assume the whole world aspires to reach the energy usage level of a typically poor (or careful) European country like the UK, the increase in energy required is:
    (10 x 3183.3) ÷ (7 x 1790.1) = 2.5 x current usage.

    I shall change the heading immediately.
