Is wave energy untapped potential?

The increase of energy demand in the past 50 years and targets to reach net-zero carbon dioxide emissions have led an electricity production from renewable sources . This paper first gives a snapshot word's mix then reviews most widely used market; comparing their reliability, efficiency cost-effectiveness, highlighting major advantages weaknesses. review concludes that marine energy, specifically wave can be emerging source capable addressing many problems current concepts devices present, although challenges remain. is focused on global position technologies market under development two decades, by looking at status, generated, capacity installed geographical locations. status main players, including France South Korea, compared with rest Europe has been reviewed special interest UK, as one Australia new area development. Wave Energy Converters (WECs) together world's density map are also discussed. conclusion, even though there high potential, developed date cannot offer much needed breakthrough. A concept WEC based system synchronized rotational pendula, having potential work across-scales introduced, which motivate future work.
