The amount of carbon dioxide in Earth’s atmosphere reached 419 parts per million in May, its highest level in more than four million years, the National Oceanic and Atmospheric Administration announced on Monday.
Oceans contain vast renewable energy potential – theoretically equivalent to more than double the world’s current electricity demand. Nascent ocean energy technologies could cut carbon dioxide (CO2) emissions from power generation and help to ensure a sustainable, climate-safe energy future.
Alongside other offshore renewable energy technologies, ocean energy – including wave, tidal, salinity gradient and ocean thermal energy conversion technologies – forms a crucial component in the world’s emerging blue economy.
