Energy and the New Reality, Volume 1: Energy Efficiency and the Demand for Energy Services (March 2010, Earthscan, UK)
This book and Volume 2 comprehensively and critically assess what it would take to stabilize atmospheric CO2 concentration at no greater than 450 ppmv. Some of the key conclusions from these books are that

Files Used to generate the ENR energy supply (Volume 1) and demand (Volume 2) scenarios, and associated CO2 emissions

Overview of the ENR and Climate-Carbon Cycle Files Posted Above
The idea behind posting the Excel files and FORTRAN code used for the Energy and The New Reality books is to permit those who are so interested to generate their own scenarios with their own input assumptions concerning population, GDP per person, activity levels per person, and physical energy intensities for various energy end uses in 10 different geopolitical regions, as well as to generate scenarios for energy supply from various C-free energy sources. Outputs from these files include global demand for fuels and electricity, annual material and energy inputs required to build a new energy infrastructure, land requirements for bioenergy, and annual and cumulative CO2 emissions to 2100 (the CO2 emissions in turn were used as inputs to a coupled climate-carbon cycle model to produce the scenarios of global mean warming and ocean acidification that are given in ENR Volume 2). The FORTRAN code applies a building stock turnover model to 2 different energy sources (fuels and electricity) in two different building sectors (residential and commercial) in the 10 geopolitical regions, and uses as input the growth in regional building floor area as generated from the Excel demand scenarios, along with a variety of other inputs.
The stock turnover model has also been implemented in Excel for one generic fuel, building type and region for those who wish to adjust the inputs to a particular region and building type of interest so as to explore the impact of alternative assumptions concerning growth in total floor area, rates of building renovation and replacement, and the change over time in the total energy intensity (annual energy use per unit floor area) of new buildings and of newly-renovated buildings.
The climate-carbon cycle Excel package (subsequently referred to as the CCC package) will be part of the online material associated with my chapter in the forthcoming 2nd edition of Environmental Modelling: Finding Simplicity in Complexity (Wiley-Blackwell, John Wainwright and Mark Mulligan, eds.). It has three parts, the first of which contains a number of worksheets that explain the physics of climate change and the development and properties of simple climate and carbon cycle model components. The second part of the CCC package contains a highly-simplified representation of the energy demand and supply framework used in my two energy books. These give scenarios of global fossil fuel emissions of CO2. The CCC package also has worksheets that give land use emissions of CO2 and total anthropogenic emissions of CH4, N2O and halocarbons (all subject to alteration by the user). The impacts (radiative forcings) of tropospheric ozone and aerosols are computed in a manner that is roughly consistent with the fossil fuel and land use CO2 emissions. The third part of the CCC package contains a coupled climate-carbon cycle model (built from the components illustrated in Part 1) that is driven by the outputs from Part 2. The climate sensitivity and a number of carbon-cycle and climate-carbon cycle feedbacks can be specified (including the possibility of eventually catastrophic releases of CO2 and methane from permafrost regions beginning slowly at some user-specified threshold temperature change).
The climate-carbon cycle model in the CCC package can be driven either with the fossil fuel CO2 emissions that are generated from Part 2 of the package, or with the CO2 emissions that are produced from the Excel package for the two energy books (these emissions can be pasted into the CCC package). In this way, those who are so interested can explore the range of possible impacts on global mean warming (given uncertainty in climate sensitivity and climate-carbon cycle feedbacks) resulting from very specific assumptions concerning future population, economic growth, activity levels and physical energy intensities at the regional level, and in the rate of deployment of C-free energy supplies at the global scale.
