During summer, demand for water in Bayhaven is estimated to exceed its existing supply by 12%. A proposed desalination plant could provide 20 million litres a day and create 35 permanent jobs. It would increase the average household water bill by £48 a year and initially use as much electricity as 18,000 homes. The operator plans to obtain 60% of its electricity from offshore wind within five years. Evaluate whether building the desalination plant would be a sustainable economic choice for Bayhaven.
