In summary:

Energy efficiency:- Delivers much lower cost per MWh energy services- Does not require any subsidies- Has additional system benefits whereas renewables have

additional system costs- Generates more jobs per €1m of activity (21) than the

average of the economy (17) and the energy industry (10)- Decarbonisation through renewables is not plausible- Over the last 30 years efficiency has delivered more

energy services than any other type of energy - & that is without us really trying!

- Think about what we can do if we really try!
