In it he set out all the possible sources of low carbon energy in the UK on one side, and all the demand we have for energy on the other and looked at how much we could decrease our demand and increase our supply and saw whether or not these actually lined up, so was it possible to meet our target and have a sustainable energy system,” explains Laura Aylett, programme manager for the 2050 Calculator at the Department for Business Energy and Industrial Strategy – BEIS. “The calculator is really an interactive version of what David did in sustainable energy without the hot air. It was time to create the carbon calculator, which later became known as the 2050 Calculator.

To achieve this a new set of tools was needed to measure the impact of different energy scenarios in reducing emissions and David had already set out the how to do this in his book. And it allowed people to judge the impact of changing elements of production or consumption.ĭavid’s approach was so simple as to be revolutionary, and it immediately captured the attention of the government who appointed him as Chief Scientist at the UK’s newly formed Department for Energy and Climate Change at a time where the country had become the first in the world to set a legally binding reduction target for carbon emissions of 80% on 1990 CO 2 emissions levels. The book enabled readers to see clearly whether the UK could power itself sustainably.


Sustainable Energy Without the Hot Air simplified the maths around sustainable energy production and consumption, using consistent units so that readers could easily understand the numeric building blocks of our energy system.
