Energy - What Next - Essay Example Offshore wind firms are more complex, inclusive of turbines, platforms, grids, cables, substations, interconnection and related construction activities. Currently, construction activities have centered in many rejoins of the U.K, representing over 3300MW of the entire capacity (Jay, 2008). I support the construction of these offshore winds with long-term charters of numerous highly specialized construction vessels and facilities to put up with the increasing dimensions of contemporary support structures, wind turbines, and balance of plant. Offshore wind farms are vital in their contribution to energy supply If these firms are constructed, they will be a suitable technology to meat the growing electricity demand, in a clean and sustainable way. Such firms will have minimal environmental impacts if they are logically well located relative to the places of electricity need. Further, higher wind speeds will increase energy production, since energy production is a purpose of the cube of the wind speed. I expect that a significant part of the future widely spread wind energy usage in U.K will be from offshore sites. Huge offshore wind farms are already in the planning phase of construction in several countries and especially in Europe. Just like Hirts put it, financial payback or economic viability of the farms depend largely on the renewable obligation Certificates, as well as on favorable wind conditions as compared to the sites constructed on land, I argue that the higher energy outcome has to recompense the extra installation and continuance costs. In constructing these farms, particularly siting large projects, a reliable and efficient offshore wind prediction is crucial (Burton & Jenkins, 2011). Present estimates based partially on U.K experience indicate that offshore wind energy can cost less than six cents per KW. In addition, capital costs are about 30-50 percent higher than those onshore because of bigger machine sizes, transporting and installing costs a t the sea, particularly offset by high-energy productions. However, just like onshore, I expect these prices to drop as technology advances and managers get more experience. As the European Wind Energy Association (2012) affirms, most offshore farms will be sited on monopiles or constructed on gravity foundations, there will be concrete structures stabilized by water or sand to allow the turbine towers to fit in. Monopiles must be included in these installations. They are long steel pipes, which are stroked, vibrated or drilled into the seabed to security levels then towers and platforms are installed on top of them. They will have a technical difficulty in mounting turbines on floating constructions, and monopiles get more expensive as one progress deeper into the water. In my opinion, technology has been growing rapidly for the past years and I can predict that technical advancements may make suspended offshore wind farms to be economically realistic in the future. Offshore wind f arms are important in energy providence. I support the construction of these farms basing on several factors. The resource, which is wind energy indirectly from the sun is extremely large, the costs of energy, though originally higher than those of onshore are affordable than most renewable technologies, and the associated risks are low. Constructing wind turbines at sea will limit the restraints that can be
