First, desalination is not inexpensive, as has been mentioned. It is expensive because it takes a lot of energy to turn saltwater into potable water. There are several types of energy sources, likeOilGas orElectricityThis kind of energy is used for local and commercial purposes. The trouble is that prices of these energy sources have been rising. Higher energy prices also make desalination more expensive. That is why many places are struggling to pay for desalinated water.
To grasp the costs of desalination, we must look beyond energy costs. We have to keep other major aspects into account as well. For example, we should consider how much it costs to construct and maintain desalination facilities. These plants are special facilities, specialized facilities that carry out desalinization. These need huge amount of money to be constructed and also need regular maintenance to keep themselves functioning.
And we ought to consider the expense of bringing the potable water where it’s needed. Once that water has been made safe to drink, it still often needs to move long distances to solutions in homes, schools and businesses. All these items are added cost, making desalinated water more costly than other sources of water we may be using in our country, such as rivers, lakes or wells.
So, can desalination be made cheaper? Yes, there are a few ways! One option is to heat with renewable energy — such as wind or solar power — rather than oil, gas or electricity. Renewable energy is cleaner and more sustainable, which could make it easier to maintain stable energy prices. On the other hand, if we manage to use renewable energ for desaltination, it would help reduce the price for producing potable water.
To further reduce costs, one option is to enhance the technology in desalination plants. Ever since, scientists and engineers have been trying to make the desalination process more efficient. That includes creating more impact with less energy used. If they can do that and then create new technologies that make desalination more efficient, it could lead to cost savings in the future.
It’s also necessary to compare the cost of desalination to that of other water sources. In many instances, obtaining water from desalination may cost more than using wells, rivers or lakes. But there are occasions when those other sources are not available. For example, it could very well be the only option on deserts in dry areas or on islands that don’t have many rivers or lakes. In such cases, desalination can save lives by supplying enough water for a population to consume or use on a daily basis.
There are some advantages to desalination. It provides a reliable source of drinking water, particularly in areas where no alternatives are available. But, of course, there are cons as well that must be kept in mind. One big concern is that desalination will kill marine life. Intakes at desalination plants can harm fish and other ocean organisms when they're sucking in seawater. Once processed, the water is then often expelled back into the ocean at a higher concentration of salt and chemicals, which can have a negative impact on the environment.
