Usually when you hear about conserving water, the concern is simply for the water itself. But water takes a considerable amount of electricity and infrastructure to treat, distribute and dispose of. T...
his chart shows the hidden environmental cost of water treatment with data used from the report 'The Carbon Footprint of Water' completed by NGO The River Network in 2009. One average shower requires approximately 50 grams of coal. Whilst this figure is most common for the USA, the embodied energy can change for different locations, taking up to six times the power represented in this chart and also less power in some areas. Water and energy conservation are completely interdependent. It takes power to treat water and also water is used in coal and nuclear power plants. This is why locally collected water such as water tanks is important because it does not require the energy intensive water treatment processed from the centralized treatment and distribution system.
