Climate & Energy

2017-06 Avoiding Climate Change Disaster

A short paper on the actions we must take soon in order to meet a carbon budget target which will limit global warming to 2 degrees and to arrive at a viable sustainable energy scenario thereafter.

2017-07-10 Climate and Energy Topics

Topic 1) emphasises the urgency of energy transition.

Topic 2) is the main focus of the document, with the paper by Sgouridis et al, 2016.
This identifies the relationship between the remaining fossil fuel emissions cap, the transition time, and the required investment in Renewable Energy (RE) supply plant.

Topics 3) and 4) refer to the initial conditions prior to the energy transition.

Topic 5) compares the Energy Return on Investments (EROIs) of Renewable Energy (solar and wind power) supply measures with the weighted average value of 20 assumed by Sgouridis et al.
Topic 6 is concerned with the global limits of renewable power sources.
Where Topics 3) and 4) deal in UK quantities, Topic 6) deals in Global quantities. However, the UK must expect to use only a proportionate share - e.g. equal per capita.

Topics 7) and 8) consider energy demand measures as complements of the supply measures assumed by Sgouridis et al. They refer to two papers by Cullen and Allwood et al, 2010 and 2010.
Including energy demand measures will greatly ease an energy transition within the constraints, such as 2 C global warming.


2013-07-22 Carbon Budgets and Switching to Renewables

This paper assembles a chain of evidence from the global Carbon Budget for permissible climate change to the choice of components of the solution based on their Energy Return on (Energy) Invested (EROI). It shows that for an 80% chance of limiting global warming to 2 C, only 565 GtCO2 can be emitted (up to 2050).

2012-08-14 Regarding 'Solar Energy in the Context of Energy Use'

The late Professor David MacKay, FRS submitted to the Royal Society the paper: 'Solar Energy in the context of energy use, energy transportation, and energy storage',

2011-09-26 Geo-Engineering Debate: Transport Fuel, then ‘Roll-back’

For a 'Geo-Engineering Debate' held at the Royal Society, I prepared - but did not give - a presentation.

2010-09 Energy Resources and Rates for Depletables and Renewables

I produced a presentation showing that the peak discovery of depletable fuels, such as oil, gas, coal and uranium, occurs some 35 years before peak production, so giving ample warning.

2007-08-13 Response to 'Planning for a Sustainable Future'

In response to the UK Government White Paper 'Planning for a Sustainable Future' of May 2007 I submitted two documents.
The first consists of the consultation questions and my answers.
The second is grouped into topics.

2007-07-03 Energy Criteria for Sustainable Energy Solutions

I was invited to give a presentation with this title at the European Sustainable Energy Forum 2007, in Lucerne, Switzerland.
