Efficient in what way? I don't care about the amount delivered vs the amount 'wasted.' I care about the cost per unit delivered. By this measure, dams are far more 'efficient.'
Read the report, tanks can be competitive with dams on a per unit basis, in the right situation.
I'd also note that when it doesnt rain, efficiency has a lot to do with the amount wasted.
And ahh... aren't you telling me that you are the one advocating less waste? And yet here you are saying you don't care how much dams waste? Make up your mind!
Quote:Again, by excise, do you mean tax?
What do you think... look it up if you have to.
Quote:Sure, a 50% reduction in the use of coal power is just as good as switching to generating 50% of our capacity from renewables. It is even better if it is a lot cheaper. The argument can be applied very broadly.
But that doesn't address the issue of sustainability now does it?
Quote:Yes it does. The real issue is not where we get our electricity from. It is how much CO2 we emit.
The issue absolutely is about where we get electricity from, non renewable resources are not sustainable.
Quote:I am arguing against wastage. You are arguing in favour of it. Subsidies are a form of waste. Spending a fortune on tanks when reduced consumption and improved efficency is far cheaper is a form of waste.
If you think I am arguing for wastage then you have not been reading what I have written. Please take the time to read everything again if you missed this point... By advocating dams over water tanks, you are advocating waste, I am advocating conservation in every sense of the word.
Quote:No it doesn't. This is the least costly option in terms of our economy. Pushing the change via subsidies is far worse for the economy.
Exactly what difference does it make?
If a subsidy means families on low incomes will adopt tank water then it is not waste. Again you seem to be massively out of touch with people on low income.
Quote:It's all relative. I would say it is elastic in the short term, and extremely elastic in the long term. Even for a short term change, taxes are a better option than subsidies.
Water use (wastage not considered) transport, food and energy are inelastic commodities. This does not mean they do not respond to price signals, it means demand will respond in a negligible way. Everything is elastic, elasticity is relative... way to state the obvious. When you say something is 'inelastic' you simply say that consumption is not effected dramatically by price, ie people have to eat, drink water, drive to work and turn on the lights. Price fluctuations don't change this, they just hurt people when they go up.
Quote:I am not arguing against any given technology. I am arguing against using the wrong economic incentives to get it implemented. The only thing you can guarantee with the wrong incentives is the wrong outcome.
So you propose to hike prices and let the market suffer the consequences until new technology is adopted? You can only conserve so much water freediver, I can really see that you have not lived off of tanks before...
Quote:Those economists you link to do not agree with you. This is not an argument about tanks vs desal vs dams. It is an argument about taxes vs subsidies and about tanks vs improved efficiency and reduced consumption.
Subsidising tanks will not return flows to dry rivers. Water taxes will.
The economists argue the case for increased subsidies!
I am advocating taxes!! I am trying to offer a solution that forces business to carry the weight of the tax, by giving households an alternative.
