the current water shortage on Oahu. For the purpose of this paper‚ our group has chosen to discuss what we believe to be the top three most feasible technological solutions. In order of current usability they are; 1. Water recycling 2. Desalination 3. OTEC (Ocean Thermal Energy Conversion) Water Recycling Water recycling here on Oahu is an important part of ensuring a sustainable water supply for future generations. Through the natural water cycle‚ the earth has recycled and reused water for millions

How can water generate Electricity? There are two primary methods for generating electricity from water. One method uses the energy potential of trapped water in dams in a more sophisticated version of the water wheel‚ and the other method of generating electricity is to capture energy from ocean waves. Electricity generated from water is entirely renewable‚ sinccete water is an abundant natural resource First method:When a dam is used to generate energy‚ tunnels are installed in the dam when
