2050 Pathways

Posted by on Sep 13, 2018 in Blog | 0 comments

As part of the update of my book, and in preparation for a two-day energy management training course I am delivering shortly,  I revisited the 2050 pathways model for decarbonisation of the UK economy by 80% by 2050.

I took the plunge and completed my own 2050 scenario, achieving an 81% reduction, summarised in the actions illustrated above. My model is heavily focused on the demand-side, as you can see from the red colours in the upper section of the screenshot above. This brings home the fact that no matter how many wind-farms we put up, unless we change our heating and transport to electricity, the supply-side changes will have little effect.

One particular quandary I had was how much land to dedicate to biomass. When I reached 78% emissions reductions, one of the few remaining ways to reach the 80% target was to increase the land use for biomass from 5% to 10%, or start to import biomass, neither of which I wanted to do. In the end, I achieved the target by turning down the average temperature in homes beyond what I really think is feasible. These kinds of decisions bring home the complexity of the energy system and the fact that no single technology can achieve the goal.

EREWTT Update – v1.3 Sept 2018

Posted by on Sep 9, 2018 in My Book, News | 0 comments

Just to let folks know that I have updated my Book Energy and Resource Efficiency without the tears – the complete guide to adding value and sustaining change in an organisation.

The ability to change the text frequently is one reason why we have chosen to go with “print on demand”. The other is that it has a lower environmental impact as supply matches orders.

The chapter on ISO 50001 has been completely updated as the standard has moved from 50001:2011 to 50001:2018. There have been other updates and corrections throughout the text including checking and updating all the web links in the 800+ bibliography at the end of the book.

The free PDF has been updated as well as the print editions. Please do download the free PDF rather than buy a print version – not only is that more resource efficient but you will always have the up to date version! However, if you absolutely insist on buying a print version, then please do order it through this site.
