Silas and Munro are off on a class visit to Peggy’s Cove, about 45 minutes west of their home in Halifax, Canada. Along the way, Silas sees how the landscape has been manipulated by man’s insatiable need for energy. Huge tidal generating stations have been constructed along the coastline in an effort to curb the country’s need for oil. Sea life in some of these areas is now non-existent.
Tidal power could provide great potential for creating large amounts of electricity in the future. It’s not yet widely used, but some view it as a more reliable source of renewable energy as the tides are predictable compared to the sun and wind. In OurGlass, I have made an effort to mention both the barrage method of tidal power generation (involving a gate system to trap the water’s outflow) and the floating generator (involving a turbine being submerged into an ocean’s current). Both are still in the development stages and their impact on marine life is still being assessed. There is no silver bullet in solving our need for energy.
On their own, these methods of power generation will not fulfill man’s total energy needs, but they could play a very important supplemental role in man’s future demands for electricity.
