Recently the climate-abusing effects of exhaust gases from combustion processes have been increasingly focused. This is underlining the importance of improving the energy efficiency. Nowadays, fishing fleet is in most cases not efficient because of outdated technology. Maintaining an adequate level of energy efficiency requires a continuous monitoring of the energy profile of the vessel. Any causes of energy inefficiency can be identified, being able to act on them promptly and effectively. A proper system of energy use monitoring is therefore essential for maintaining high-energy efficiency. Once energy use has been related to each operating condition, fishers can minimize fuel use. Energy efficiency in fisheries can be investigated through Energy Audit, which allows obtaining an extensive energy profile of the fishing vessels monitored. Vessel Energy Audit assesses the energy consumption of each energy user (e.g. propulsion system, electric- and hydraulic-user). Energy audits have been conducted for fishing vessels, which lead to recommendations for improved efficiencies to solve present and possible future fuel cost increases.
