  • We should never forget energy efficiency – my favorite subject. It may surprise you to learn just how inefficient we really are. Research from the University of Cambridge shows that we put 475 units of energy (fuel, nuclear, everything) in and we actually only usefully use 55 units – a total efficiency of about 11%. Isn’t that amazing – all of our technology and the best the world can do is 11% efficiency!
  • Now – show me the moneyAs an aside Boulton & Watt who are pictured here – made their money by implementing energy efficeincy – the Watt steam engine was much more efficient than the existing technology and saved coal mine owners a fortune. Bolton & Watt had the first example of shared savings deal – they took a % of the savings over a long term contract.Now I am going show you some big numbers
  • Attractive to one of the richest New York property owners – Tony MalkinAs Tony said to me, I am a green but business is business and I only invest on a 3 year payback period – and what is more everyone in the New York property world knows that.
  • Well, breaking down the problem we need to do three things:Massively expand demand for energy efficiency across the economyMassively expand the supply of energy efficiency products and servicesMassively expand the availability of finance for energy efficiency

    18. 18. In summary:Energy efficiency:- Delivers much lower cost per MWh energy services- Does not require any subsidies- Has additional system benefits whereas renewables haveadditional system costs- Generates more jobs per €1m of activity (21) than the averageof the economy (17) and the energy industry (10)- Decarbonisation through renewables is not plausible- Over the last 30 years efficiency has delivered more energyservices than any other type of energy - & that is without usreally trying!- Think about what we can do if we really try!© Steven Fawkes 2013
