OK what? You accept renewable energy systems are very scalable?
And you've worked out what 7% per annum conventional hydrocarbon depletion rate (that's about 40 million barrels a day in 10 years)
which 10 years are you talking about here?
if you're talking about the next 10 years then you're offering by far the most pessimistic predictions I've seen so far, and I don't see any justification for it at all. the only way I could see this being even close would be if you were to only look at currently producing fields under the worst case scenario of their declines, and not take any account at all even of any of the fields that are currently being developed. If you've got reason to doubt any contribution at all from fields currently under development please post up your reasoning, if not then your figures are seriously out, so it's not surprising you've decided we're into doomsday scenario territory.
40 million barrels a day being a more than 50% drop on current levels btw for anyone wondering.
plus 1% growth to maintain the stability of the financial system
economic growth and energy growth are none linear, ie there could be a 1% economic growth rate maintained even with a 1% per annum reduction in energy if energy efficiency was increasing at 2% per year (or something like that).
translated back into equivalent solar capacity (annual incremental capacity addition) is?
of course not. Aside from your oil depletion figures being wrong, at no point have I suggested that solar can replace oil along. Alongside all the other renewables and energy efficiency measures, and with a more realistic prediction of depletion rates (including new fields etc) however there's every possibility that we'll be able to replace the lost oil availability as it depletes IMO.
You've factored in that the solar manufacturing infrastructure (the factories that make the mining equipment that excavates the ore, the factories that smelt and refine the ore, the trucks that move the refined products to factories for assembly, the assembly factories, the infrastructure associated with the electronics and physical assembly of the units, the infrastructure associated with the manufacture of the distribution infrastructure, etc. Etc. ETC. ) is all currently manufactured and currently powered by hydrocarbon. You've worked out how much power you have left for us after you've plugged all that into the output of your little test plants? You've worked out the capital demand schedule on a £/kW capacity inherent in that depletion/expansion rate?
Firstly, to a large extent, if these people, finance and energy resources weren't deployed in this way, they'd only be getting used for something less useful.
secondly - no, it's not all powered by fossil fuels, approx 20% (and increasing rapidly) of world electricity production is from renewable sources, and 13% from nuclear.
Thirdly - yes renewable energy manufacturers, distributors and installers need to take great care to minimise the embeded energy and resource use within these installations, and it's something I'm working on, but it's frustratingly hard to get any real information out of our suppliers.
