The most vital matter of the 21st century is climate change, due to the obvious increase in our energy usage.
Considering that the needs in energy will continue to grow, the only path to keeping in check the negative impacts on the environment, and humanity, is the use of every kind of renewable energy source. Among all forms of renewable energy, the least utilized and exploited one is Blue Energy.
Blue Energy is elaborated as each kind of energy that is generated in the sea/ocean, such as wave, tidal, energy from ocean currents, and also offshore wind and solar energy. Some 71% of our planet’s surface is oceans; thus, the ocean environment becomes a large source consisting of different sources of renewable energy, having the capability to play a catalytic role in keeping in check the energy and environmental issues of our planet. The total available wave power that can be used is 3 Terra Watts (TW), which goes past the required power to cover the world’s needs of electricity (2.3 TW). Taking this advantage into consideration, wave energy becomes a preference for electricity generation.
However, its usage is disproportionately less as compared to wind and solar energy. The main reason for this failure might be the deficiency of understanding and perception of the wave’s properties, which is accountable for the type diversity and numerous wave energy converter (WEC) devices that have been made and studied.
Analyzing the state in Cyprus, one could say that it is not worth investing in this section since the existing devices require larger wave heights to start working. However, using the same mindset, one can say the investment in wind energy should not be made as wind power potential in Cyprus is lower than in other regions of the planet. Yet, wind energy in Cyprus is almost 5% of the total electricity, while it continues to increase.
