Quote:The net pollution from establishing base load sufficient wind, solar, flow batteries and implementing these technologies on a large scale has not been fully investigated.
Neither has nuclear. Howards plan for 25 nuclear plants will amount to some 10% of our power consumption...hardly base load.
You are also forgetting that climate change is not just about CO2, dumping vast quantities of waste thermal energy into the biosphere is still a massive problem that nuclear plants do not solve.
Quote:Modern batteries have their own set of environmental problems. Ignoring these and pushing the tired uranium scare-mongering doesn't make them go away.
Lead acid batteries are one of the most successfully recycled goods we have. Either way, battery waste is not on par with radioactive waste in terms of cost of disposal, or future environmental impacts.
There is no need to scare monger about the dangers of radioactive pollution, it is simply uneconomical to deal with.
Quote:Can you say desert? Can you say ocean?
Power transmission presents a problem for this scenario
Not if you convert the electricity directly into stored chemical energy. This is the way we should be heading anyway, power grids have their own problems.
Neither would it be a problem if we encouraged a decentralisation of power supply (as should be the case for water too). But oh no don't ask anybody to take responsibility for their own existence now...
Quote:The fact is, the govt and the opposition have both recognised that renewables will only ever make up a fraction of the power requirements needed for the Australian population. Anything else is only a pipedream at this point in time. That's not to say it won't be in the future, but they cannot produce the demand that industry requires.
And neither will nuclear... seeing a pattern yet?
Quote:Even the international energy community recognises that renewables are only good for 15-20% of glabal energy.
At current levels of consumption, and current levels of technology. This is why it is important to make people respect the resources they consume by giving them a decent signal through price. This is also why it is important to create a market for these technologies so we can make the engineering advancements that are being stifled right now by this white elephant of a debate over nuclear. Howard announced more money to be spent on chaplains in schools last year than his much touted solar energy funding, and we are looking at investing many more millions of dollars into nuclear plants that won't even come close to base load and even then not for 20 years. Renewables may not be economic for base load TODAY, but TODAY they can do what nuclear can only do in the future. If we just put the money into technology that is ON THE MARKET, made by AUSTRALIAN companies we could have the sort of figures Howard is talking about within 5 years, not 20. And an expanding market for renewables that will create demand for innovation... oh no no, forget that, nuclear is coming...one day...I think...
Coal is a non renewable resource, uranium is a non renewable resource. Ziggy was on the TV the other night and said we have maybe 100 years of uranium as a power source in the world...great plan for sustainabilty there.
