Wind energy is considered as the most efficient energy of all the renewable energies available globally. This is because it does not emit toxic substances and wastes and do not contaminate air or water. Wind farms can be based onshore (on land) or offshore (sea or freshwater). As per the data by the World Wind Energy Association (WWEA), 80 countries across the globe are already using wind power on a commercial basis, wherein prominent countries, such as the U.S., Canada, and the U.K. are ranked first, second and eighth, respectively in terms of installed capacity (both onshore and offshore).
Offshore wind power, i.e. the kinetic energy of the wind, is one of the sources of clean and renewable electricity/power for countries across the globe. The offshore wind power involves using energy from wind turbine to generate electricity. Wind farms are constructed off the coasts, usually on the continental shelf to produce the wind energy for electricity generation. The offshore wind energy technology has attained considerable growth in a very short span of time, but there is clearly much development expected in terms of technological advancement. Increase in investments by governments, especially in the developing countries, such as China and India, rapid urbanization, and rising demand for clean and renewable energy, are expected to support the market growth of offshore wind energy.
Offshore wind turbines prove to be more competent than onshore wind turbines due to the more consistent wind speed and direction. Due to this, less number of turbines are required to be installed to generate the same amount of electricity as compared to onshore turbines. Moreover, offshore wind turbines do not interfere with regular land use. These prove to be advantageous with high energy potentials associated with the large areas and the stronger winds. Offshore wind infers better power generation; however, they have higher initial investment, operation, and maintenance costs. Although the fundamentals of technology are the same in both onshore and offshore, the offshore wind technology is expected to witness more advancements than the onshore technology.
According to the latest report, titled ‘Global Offshore Wind Energy Market: Analysis and Forecast (2018-2023)’, the global offshore wind energy market is projected to reach $50.45 billion by 2023. This growth is attributed to the rising demand for renewable energy sources for power generation, increasing investments in the offshore wind energy sector by several companies and government of different countries, and the government initiatives to reduce the carbon footprint.
