Harnessing Ocean Energy: A New Frontier in Renewable Resources
As the demand for electricity continues to surge globally, conventional energy resources are increasingly being pressured to meet this need. Covering over 70% of our planet, oceans present a significant opportunity for clean energy generation through renewable means, particularly from ocean currents and wave action.
Emerging Challenges in Marine Renewable Energy Development
Despite their promise, marine renewable energy technologies lag behind established sources like wind and solar power. A key obstacle is pinpointing the most practical and economically viable sites for harnessing ocean current energy. Traditionally, studies have concentrated on regional assessments of these resources; however, comprehensive global analyses utilizing actual data have been scarce until recently.
A team of researchers has investigated the potential to capture kinetic energy from ocean currents by examining how power density varies over time and different geographic locations. Utilizing approximately 1,250 satellite-tracked buoys that continuously monitor ocean currents along with their geographic positions—analyzing more than 43 million data points collected between March 1988 and September 2021—the study aimed for a broad evaluation of this resource.
Key Insights on Power Density Distribution
Published in the journal Renewable Energy, the research highlights that regions off Florida’s East coast and South Africa consistently demonstrate high levels of power density—ideal conditions for electricity generation via ocean currents. Specifically, these areas showcased power densities exceeding 2,500 watts per square meter—approximately two-and-a-half times more potent than an exceptional wind resource. Furthermore, their relatively shallow depths (around 300 meters) enhance feasibility for deploying turbines designed to extract current-based energy efficiently compared to deeper water locales such as Japan or certain sectors in South America where lower densities prevail at similar depths.
“Our findings indicate that nearly three-quarters of all identified high-power density zones span roughly 490,000 square kilometers across various seas; within these areas reside considerable potentials with densities ranging between 500 and 1,000 watts per square meter,” commented Mahsan Sadoughipour, Ph.D., first author and graduate researcher at the College of Engineering and Computer Science. “This suggests ample opportunities exist particularly where prevailing conditions yield moderate yet adequate power outputs suitable for sustainable practices.” Furthermore, he noted how environmental factors alongside measurement techniques could significantly affect precision outcomes when estimating potential yields.
The Geography of Power Densities
The study illuminated regions exhibiting potent marine energies surpassing thresholds set at greater than previously recognized parameters (e.g., above paradigm levels like those benchmarked at higher than approximately two thousand watts). This encompasses stretches along Southeast U.S coastlines extending from Florida up towards North Carolina as well as African shorelines (incorporating countries such as Somalia through Madagascar). Conversely diminished values occur within territories spanning parts located within Eastern Pacific realms including Japan — further south extending into Vietnam—as well areas adjacent around Brazil’s northern coastlines observing less reliable outputs generally associated near French Guiana alongside indicators recorded around Australian coastal expanses.

Harnessing Ocean Currents: Overcoming Challenges and Seizing Opportunities
The deployment of underwater turbines presents formidable hurdles, primarily due to the necessity for advanced anchoring systems that ensure stability and consistent performance. The increased depth in which these turbines operate also exacerbates installation and maintenance complexities, underscoring the urgent need for innovative technologies suitable for such challenging aquatic scenarios.
The Impact of Seasonal Changes on Renewable Energy Availability
Seasonal fluctuations have a profound influence on energy availability derived from ocean currents. During the warmer months in the Northern Hemisphere—from June to August—regions such as Florida, Japan, and Northern Brazil exhibit higher power densities, coinciding with heightened energy demand during this period. Similarly, South Africa experiences peak power densities during its summer months (December through February). This seasonal alignment suggests that ocean current energy could be an increasingly dependable source of renewable power when electricity consumption surges alongside rising temperatures and air conditioning usage.
Critical Factors in Estimating Ocean Current Energy Potential
“The accuracy of ocean current energy estimates hinges on several essential elements: data density, data types utilized, and flow variability,” stated Dr. Stella Batalama, Dean of the College of Engineering and Computer Science. “Insights derived from this research underscore the importance of meticulously considering these factors to ensure that ocean current energy can be seamlessly integrated into the broader framework of renewable resources.”
Innovative Developments in Southeast Florida’s Renewable Energy Sector
“This pioneering study reinforces Southeast Florida’s position as a leading contender for tapping into ocean current potential,” noted Gabriel Alsenas, Director at FAU’s Southeast National Marine Renewable Energy Center (SNMREC). “At SNMREC, we are committed to spearheading advancements in domestic energy solutions by harnessing our unique access to plentiful ocean currents. Our efforts are pivotal in fostering groundbreaking technologies aimed at enhancing not only regional but also national energy resilience.”
