- A study for the Swedish State Power board showed that with increasing end use
- energy efficiencies, CHP, and switching to biofuels, and lower carbon fossil
- fuels
- (ie gas), that country can eliminate it's nuclear programme, support a 54%
- larger
- GNP, and have a $1billion per annum saving in the cost of electrical
- services.
- Over the timescale of the study it allowed 1.9% growth in GNP per annum. In
- the
- Energy without Oil report, they may have covered this, but since neither you
- nor
- I have read it, we won't know will we?
-
- # 4) no mention is made regarding handling the developing countries
- which can
- # potentially cause an explosion in the need for energy
-
- Yes it certainly can, especially if the developing countries follow our
- examples and
- go straight for fossil fuel based power, and use inefficient technologies.
- However
- remember that in the developing countries, there is the possibility of them
- leapfrogging from their current technologies to the highly efficient
- technologies
- that we could use to cut our energy demands with. Of course this would require
- aid
- in the form of money, technical expertise and the transfer of the
- technologies
- themselves, but it would prevent a lot of environmental disruption, and be
- much
- cheaper than if they carried on with the current inefficent technologies.
- Also
- remember again that this was a brief summary that was posted to the group, the
- full
- report may indeed deal with this.
-
- # Statments like these which presuppose fundamental change in worldwide
- wpolicy
- # without explicitly addressing these policy changes directly strike me as at
- best
- # misleading. Why not come out and express the realities:
- #
- # 1) Population growth must be controlled world wide
- # 2) Standards of living in the devleoped world will drop by perhaps as
- much
- # as 1/3 to 1/2
-
- Not necessarily. If efficient use of energy and resources is vigorously
- pursued,we
- can maintain our high living standards whilst considerably reducing the impact
- on
- the environment.
-
- # 3) Business will have to undergo major restructuriong to approach
- zero
- # emmisions and massive recyclin
-
- I wouldn't disaggree about this, just point out that it may well be necessary
- anyway.
-
- # 4) progress in the devloping world will be slowed by a rigorous need
- to
- # support the environemntal controls which are at least being
- # attempted in the developed world today
-
- But efficient technologies would provide them with a chance to develop a lot
- more
- easily whilst still supporting the environmental controls.
-
- # 5) Nonfossile energy sources need to be the predominant energy sources
- in
- # the developing world
- # 6) Nuclear energy sources will become ever increasingly important
-
- Not necessarily, I'm getting the data together at the moment which shows that
- renewables can supply our energy needs.
-
- # My list may not be complete, may overspecify some items etc., but these are
- the
- # classes of policy changes required world wide for visions such as the
- proposed
- # fossile free energy world to be achieved.
-
-
- I doubt if anyone would dare to suggest that we can achieve a fossil fuel free
- world
- without some far reaching changes. This report I suspect demonstrates the
- technical
- possibility of doing so, but I wouldn't be surprised if it offers at least
- some
- pointers as to how the changes are actually implemented. We'll need to wait
- until
- full report is published before we can find out though.
