I see you're intent on actually avoiding having to clarify your position on that specific statement though, but I hope it's been noted by anyone interested that you've failed to back up your statement with hard data.
You were provided with three independent sources of data, each counterfactual to your claim that the energy supply can still grow.
1. On EROEI, you were provided with a link to "Searching For a Miracle: Net Energy Limits & The Fate Of Industrial Society" (Heinberg 2009). Heinberg is an authoritive author in the field of energy analysis, publishing under the International Forum Globalisation, an international research, education and activism institute comprising leading scholars,economists and activists. I made the study and report, and its fully referenced data available to you in downloadable form. I provide it again
here (PDF). It surveys each of the major candidate energy groups (oil, coal, gas, hydropower, nuclear, biomass, windpower, PV, active solar thermal, passive solar thermal, geothermal, waste, ethanol, biodiesel, tar sand, oil shale, tidal power and wave energy) and evaluates each against nine key criteria: monetary cost, dependence on additional resource, environmental impact, renewability, scale of contribution, resource location, reliability, energy density (gravimetric, volumetric and areal), transportability, and EROEI. It provides detailed, fully referenced data on each of those metrics. From its introduction:
"The scale of denial is breathtaking. For as Heinberg’s analysis makes depressingly clear, there will be NO combination of alternative energy solutions that might enable the long term continuation of economic growth, or of industrial societies in their present form and scale."
I'm indifferent as to whether you agree or not, to your manufactured confusion between net and gross energy quantities, and to your manufactured confusion about timescales. I'm inviting the interested reader to compare your accusation that you were not provided hard data with the data you have been supplied with, and to consider your motives for claiming dissatisfaction.
2. On primary energy depletion rate, you were provided a reference to "World Energy Outlook 2008", published by the International Energy Authority - an authoritative institution comprising leading scholars and economists, constituted by the European Goverments to undertake research and policy advice in global energy. I have given detailed quotations and references to the relevant data previously (e.g. in
this post), and extensive graphs throughout this post derived from this data applied to IHS CERA (another authoritative energy institute) data e.g.
I'm indifferent as to whether you agree or not. I'm inviting the interested reader to compare your accusation that you were not provided hard data with the data you have been supplied with, and to consider your motives for claiming dissatisfaction.
3. On climate change, you were provided with a reference to a Guardian article (
link), which in turn reproduces detailed statistics from the International Energy Authority's "World Energy Outlook 2011" e.g.
If the world is to stay below 2C of warming, which scientists regard as the limit of safety, then emissions must be held to no more than 450 parts per million (ppm) of carbon dioxide in the atmosphere; the level is currently around 390ppm. But the world's existing infrastructure is already producing 80% of that "carbon budget", according to the IEA's analysis, published on Wednesday. This gives an ever-narrowing gap in which to reform the global economy on to a low-carbon footing. If current trends continue, and we go on building high-carbon energy generation, then by 2015 at least 90% of the available "carbon budget" will be swallowed up by our energy and industrial infrastructure. By 2017, there will be no room for manoeuvre at all – the whole of the carbon budget will be spoken for, according to the IEA's calculations. And you were provided with a link to The Carbon Tracker Initiative's award wining report, "
Unburnable Carbon: Are the world's financial markets carrying a carbon bubble" (PDF), showing in detail how we can burn only 565GtCO2 of the 2,795 GtCO2 contained in the proven reserves owned by private and public companies and governments - 20%.
I'm indifferent as to whether you agree or not. I'm inviting the interested reader to compare your accusation that you were not provided hard data with the data you have been supplied with, and to consider your motives for claiming dissatisfaction.
I am calling your sophistry and I don't expect you to embarass yourself with further claims that you have not been provided with hard data. I hope that puts an end to wasting the interested reader's time on this futile line of defence. I'll deal with your other howlers separately, to ensure you can't skip past the tricky bits.
