And we moan about the weather!

Australia - the country that wastes huge amounts of it's drinking water on their lawns

One gardener we spoke to for Costing the Earth told us that 90% of his water usage is for his garden and that it would break his heart if he ever had to stop watering and give up his beloved green lawns.

Yes, it's an expensive business.

In the last 30 years, the amount of energy required for desalination has fallen precipitously, and along with it the price. Decades ago it took approximately 12 kilowatt-hours of energy to produce one cubic meter of freshwater using RO technology; today it takes on average between 3 and 4 kilowatt-hours of energy. Even today, however, the cost of that energy makes up about 40 percent of the total cost to produce each cubic meter of water.

That's 3 kWh per 1000 litres though, so at 10 pence per kWh = 30p per 1000 litres. Multiply by 2.5 times to factor in other costs = 75p per 1000 litres, or 0.075 pence per litre. RO is a lot cheaper than importing water bottles I'd say, not including capital and depreciation costs, etc. Distillation would probably take 200 times that amount of energy.

Why is it called wastage to water the lawn when the gardener does it, but just called rain when God does it?

Why is it called wastage to water the lawn when the gardener does it, but just called rain when God does it?

So to extrapolate; gardeners are God, and to question him is heresy and deserves beheading?
