Desalination is primarily accomplished through reverse osmosis (forcing water molecules through a semi-permeable membrane) or distillation (evaporating salt water and then condensing the vapor). Both processes require large energy inputs to accomplish.
Carbon footprints will be increased by 180 kgs per 60, 000 of water, and that equates to a full tank of gasoline; however, that is less than traveling from Perth to Sydney!

On the other foot, the construction costs are very large, the running costs are big and ongoing, and there is still resistance from the neighbors on the impact on the local community from construction and also from having a large, noisy, 24/7, industrial-size building stuck on your local beach between the houses bought for the ocean view and the ocean.

Desalination is expensive because it requires what?
Desalination requires a lot of of energy or electricity, which makes it expensive.
Is desalination expensive because it requires a lot of energy?
yes
Desalination is expensive because it requires?
It is expensive because if requires a great deal of energy or electricity.
Is desalination important?
Yes. The Earth's water is running out and we need new ways to take water and make it fresh. There are many forms of desalination, but many are very expensive. Less than 1% of the Earth's water is fresh and many people are polluting the very little water we have.
How expensive is desalination?
Depending on the size of the desalination plant and where it is being built it can cost Millions of Dollars to buid but seem to produce very clean water for between US$0.49 and US0.53 per cubic meter. The costs are coming down, the quality is going up and the choises available are getting wider.

Reverse osmosis is more expensive than the evaporation method of desalination TRUE or False?
false
Is the expensive process of removing salt from sea water to produce drinking water?
This process is called Desalination.
How attractive are desalination and water-purifying technology?
The desalinated water is more expensive but in many countries is absolutely necessary.
Why is desalination of water and the use of icebergs as fresh water options are too expensive to be used at the moment?
Icebergs are a long way from where the water is most needed, so getting them to where they could be used would cost a lot of money. Desalination is used, to some extent, but it requires a fair amount of machinery and energy, which also means that it's expensive.
