Will Scotland rule the waves?

Scotland is ready to embark on a major national initiative to harness the power of tidal energy. According to an article posted at www.scotsman.com, the website for the newspaper The Scotsman, wave energy could provide electricity for 750,000 of Scotland's 2.3 million homes by 2020. The country recently granted leasing rights for the projects to seven companies, ranging from global utilities to smaller Scottish renewables firms.
