Harnessing just 2% of the energy potential from tidal and offshore solar sources could make a significant dent in global CO2 emissions, new research has found.
Researchers at the Universities of Strathclyde and Maine examined more than 660 assessments of offshore renewable energy (ORE) potential in more than 3,000 locations worldwide. They found that tidal and solar consistently had more energy to offer than other sources such as wind and wave, but were the subject of far less research, and consequently, remained largely untapped.
Offshore solar energy, in particular, was found to be more reliable and less variable than other sources, making it ideal for energy mixes. Despite their lower theoretical potential, wind and wave energy accounted for three-quarters of the assessments examined by the researchers.
