Renewable energy options are increasingly being promoted in response to the global challenges of climate change.
Wind power is a clean, sustainable and renewable source that doesn’t produce emissions that contribute to the greenhouse effect by absorbing radiation, unlike fossil fuels from non-renewable sources that emit carbon dioxide and other pollutants.
Wind is an abundant natural resource available worldwide, and clustered wind turbines have great capacity to make electricity for population needs and industrial activities.
Wind currents can be very strong offshore, stronger than on land and along the coasts, and with water covering 70% of the planet’s surface, offshore wind currents are a generous source of airstream.
Wind and tidal energy in offshore wind farms work on the principles of transfer of thermal energy from natural resources into usable power and commercial utilization.
The turbines use natural airflow to create mechanical energy that is converted to electricity.
Offshore wind power is yet to show greater potentials for electricity supply in order to be fully competitive with carbon-based energy sources, focusing more on population clusters as opposed to outlying territories where suitable offshore sites near the coast may be scarce.
But, in order to minimize ecological damage from wind farm projects, during the implementation, construction and initiation stages, all environmental strains must be considered.
Wind and their supporting mechanisms can severely intrude on regular ecosystem cycles, thus causing some species and entire populations of animals and organisms to dislocate, triggering a chain of order which effect certain food levels and production rhythms, impairing future progress.
The turbines are embedded directly into the ocean floor, and thus their construction, assembly and wiring that allows the energy to be stocked and re-supplied can damage the area in terms of natural surroundings of animals, plants and other organisms inhabiting it and depending on it. Consequently, the seabed is always disturbed during decommissioning as the removal of sediments leads to the direct loss of habitats and the increase of local water muddling from suspended solids, as well as redistribution of contaminants.
