Production at first increases approximately exponentially, as more extraction commences and more efficient facilities are installed. At some point, a peak output is reached, and production begins declining until it approximates an exponential decline.
"The World Energy Council has estimated the ‘useful’ global ocean wave energy resource as ... >2TW (17,500TWh/year). From this it has been estimated (Thorpe 1999) that the practical economic contribution from wave energy converters could be 2,000TWh/year (similar to current installed nuclear or hydroelectric generation capacity). Such generating capacity could result in up to 2 billion tonnes of CO2 emissions being displaced from fossil fuel generation per year - similar to current emissions from electricity generation in the US."
… if the chocolate were burned for energy, it could provide 5500 gigajoules (1,530,000 kilowatt-hours)--enough to power a town of 90,000 people for a week. "Chocolate is biomass," says Gaynor Hartnell of the Renewable Energy Association in London. "It is also very calorific, so burning seems a sensible idea."
