Solar vs Geothermal and Wind

There's more to renewable energy than just wind and solar power - hydro, wave, geothermal to name a few. Discuss these RE alternatives here!

We are asked to believe that the best scientific brains in the world are dreadfully worried that carbon emmissions are likely to cause our world to end, yet not one of them has made a comment about the fact that the world population is expected to continue doubling every 40 years. It doesn't matter how many "50/50 by 2020" type policies are promoted, if the worlds population is to double every 40 years anthropogenic climate change would never be beaten. If the scientists were conscience driven, or real fear driven instead of dollar driven they would clearly be making noises about population control.

However, it should be obvious to everyone that spewing pollution of any kind into our environment is a dumbo action. We DO need ways of stopping our pollution, but we need real solutions that actually reduce emmissions, not the ineffective dollar-driven solutions we are being offered.

Take the solar panels on domestic roofs program. Imagine if all those panels were in one spot - the economies of scale would make it vastly more cost effective and there would be vastly less embodied energy. However, the current arrangement is very visible and thus we can all feel warm and fuzzy about how our government is helping to save the world.

As to wind farms, less said the better, but until someone invents a viable way of storing electricity these things are complete duds, but again very visible to the punters and very lucrative to the big end of town.

Bah, we are being conned!


Brilliant post Willandra !

Population growth alone will ensure that the worlds combined efforts at reducing carbon emissions will be negated 10 fold.
Not that it is important because we have no idea what all these CO2 emissions are doing if anything except making people more wealthy.

Joey - could you please supply some more detailed information on "...many of the worlds greatest scientist no longer support....."
If there are "many" it should be easy to give us a big list of names and publications.

Here is a public register with names links etc

CLIMATE SCIENTISTS' REGISTER ENDORSERS

If you are a someone who has professionally studied the causes of climate change and you would like to add your name to the below list of scientists who endorse The Register .

The Climate Scientists' Register
“We, the undersigned, having assessed the relevant scientific evidence, do not find convincing support for the hypothesis that human emissions of carbon dioxide are causing, or will in the foreseeable future cause, dangerous global warming."


Another list of over 700 scientists.

for the epw site-

"New study finds IPCC "consensus" an "illusion"

"Akasofu is one of the 700+ scientists listed in a report issued by the Republican minority of the United States Senate Committee on Environment and Public Works entitled More Than 700 International Scientists Dissent Over Man-Made Global Warming Claims Scientists Continue to Debunk “Consensus” in 2008 & 2009 who are said to dispute the theory of anthropogenic global warming.

For baseload power, I'd be gunning for geothermal along with some wind thrown in for good measure. Solar is best suited to peak demand, for obvious reasons. However, I do feel energy efficiency measures deserve a lot more attention than they currently are. For example, the insulation rebate scheme should be reintroduced, with extra checks and balances, such as needing a thermal performance assessment of the candidate building performed by an accredited HERS assessor to determine optimum insulation levels and where in the building to place them for the best performance per dollar spent to an agreed maximum value. If anything, it'd help keep rogue operators to a minimum.
