 Brazil has a large coastline with many different shorelines and geomorphologies, making it ideal for wave energy production. A recent study identified 319 locations along the coast that could potentially host wave energy farms equipped with onshore oscillating water columns, OWC. These locations have a combined power capacity of 9.84 gigawatts, GW, enough to meet the energy demands of Rio de Janeiro, a city of over 17 million people. The study also found that if these locations were used to generate wave energy instead of gas-fired thermal generation, they would reduce carbon dioxide emissions by 44.52 million tons per year. This shows that wave energy can play a key role in helping Brazil transition away from fossil fuels and towards cleaner sources of energy.
