Renewable energy The source of alternative power generation to replace or substitute fossil fuels has deepened scientific understanding and innovation; in doing so, the world’s warming and its impacts have been reduced to some level, that is, in an environmentally friendly manner. Renewable energy might not be total without effect or impact on the environment, but it may be less than fossil fuels. “Human pressure has resulted in biodiversity loss and structural changes in marine ecosystems on local and global scales, with seas of northern Europe being among the most affected.” (Hammar et al., 2016)
According to Marine Energy Basic, marine energy is renewable energy or power harnessed from the natural movement of water, including waves, tides, and river and ocean currents. Marine energy can also be harnessed from temperature differences in water through a process known as ocean thermal energy conservation (Marine Energy Basic, n.d.).
Categories of renewable energy sources. Wave/tidal energy: This energy is generated from tides or waves in the ocean. Turbines can capture or transform it.
Wind energy is a form of energy that wind turbines produce. By rotating the blades, they transform kinetic energy into electricity.
Solar energy is gained from the sun's rays through photovoltaic (solar panels) or concentrated solar power.
Geothermal energy: Heat energy derived from the earth’s crust.
Hydropower: This energy is obtained from freshwater using turbines to generate electricity.
Biomass: This involves using plant and animal matter to generate energy. These materials can be converted into biofuel to produce heat, electricity, or fuel.
Offshore Wind Energy (OWE) in Europe
Offshore energy is one of the world's leading alternative energy sources, leading Europe with great power supplies, economic growth, and less or non-carbon footprint.
The European Union (EU) has five basins, which are potentially excellent for offshore wind and ocean energy. This energy plays a great deal in the energy transition. Historically, the first offshore farm was initiated in Demark in 1991. The EU is currently the world's leading manufacturer of turbine components, foundations, and cables. (Offshore Renewable Energy, n.d.).
“The renewable energy of the seas consists of many different sources that are abundant, natural, and clean, like wind, wave, and tidal energy” (Offshore Renewable Energy, n.d.).
Wind power is one of the purest and most sustainable ways to obtain electricity because it emits no harmful pollutants or greenhouse gases. Wind is abundant, inexhaustible, and inexpensive, making it a viable and ubiquitous alternative to fossil fuels.
Despite its immense potential, wind power generation has several environmental consequences that must be recognized and handled.
