Maria van der Hoeven, executive director at the International Energy Agency (IEA) said that ” the drive to clean up the worlds energy has stalled”.
Hoeven added: “Despite much talk by world leaders, and despite a boom in renewable energy over the last decade, the average unit of energy produced today is basically as dirty as it was 20 years ago.”
28 countries make up the IEA membership , which includes the UK. The Energy Sector Carbon Intensity Index (ESCII) shows how much carbon dioxide is emitted to produce a unit of energy and it stood at 2.39 tonnes of CO2 per tonne of oil equivalent (tCO2/toe) in 1990.
In ten years, this fell to only 2.37 tonnes 2.37 tCO2/toe.
The IEA report showed however, that from 2011 to 2012 photovoltaic and wind technologies grew by 42% and 19% respectively.
