Our oceans, covering over 70% of the Earth’s surface, are fundamental to global ecological stability. However, due to humans’ anthropocentric perspective, oceans face many threats. If unaddressed, these threats can trigger irreversible consequences that spin out of our control.
Since 1992, the United Nations has celebrated World Oceans Day on 8 June to raise awareness about the deteriorating situation of the oceans and promote conservation efforts.
This year’s theme is “Awaken New Depths.” One goal is to promote a sustainable approach to utilizing the ocean and its resources.
The Significance of Oceans
Oceans are our planet’s connecting factors. They have unparalleled influence on global ecosystems, climate dynamics, and socio-economic landscapes.
Oceans harbor an extensive range of biodiversity including marine ecosystems that reach from microscopic plankton to majestic whales.

They also possess the capability to produce energy to power industries, households, and more.
Oceans serve as prime locations for developing renewable energy projects, offering opportunities to harness wind, hydro and tidal energy. By revolutionizing electricity generation methods, these projects help pave the way for a sustainable future.
Sustainable approach towards oceans
A sustainable approach to oceans will result in a relatively more sustainable world. Sustainable Development Goal (SDG) 14, ‘Life Below Water,’ aims to conserve and sustainably use the oceans, seas, and marine resources.
Oceans are an untapped reservoir of immense potential with diverse avenues for sustainable energy generation.
A sustainable approach to the blue economy is important if we are to reap the benefits of the ocean.
The Blue Economy
The World Bank defines the blue economy as the “sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of the ocean ecosystem.”
According to the Grantham Research Institute on Climate Change and the Environment, the blue economy is worth $1.5 billion globally per year as of 2023. However, its worth has lowered due to an increased emphasis on the ‘green economy’.
However, the interest seems to be spiking in the blue economy and is “indicated by the OECD prediction that the ocean economy may double in size to $3 trillion by 2030”, according to the Grantham Research Institute on Climate Change and the Environment.
According to research titled “Renewable Energies and Blue Economy: New Trends in Global Research,” the renewable energy sector and the blue economy have a synergetic relationship and can work together to tackle climate challenges and promote sustainable development.
Renewable energy meets the blue economy
The International Renewable Energy Agency (IRENA) underscores the significant relationship between renewable energy and the blue economy, emphasizing their potential to work together for sustainable development.
Offshore renewable energy sources, like wind, solar, and emerging ocean technologies, might play a crucial role in this partnership, offering clean electricity while driving economic growth in maritime industries and coastal communities.

Using solar and wind power to turn saltwater into drinking water helps the blue economy by keeping water sustainable and protecting marine life. It’s a way for countries to get clean water without significantly impacting the environment.
Renewable energy also has the potential to transform maritime transportation, with renewable-based shipping offering a sustainable alternative to traditional fuels.
Countries can reduce emissions and minimize environmental harm by adopting technologies like electric propulsion for short-distance sea transport.
The report mentions that offshore renewable energy sources or technologies such as wind, solar, and other upcoming ocean technologies have an important role to play in bringing the blue economy and the energy sector together.
This partnership will promote the production of clean electricity while also increasing sustainable economic growth in industries related to marine life.
