Generating Electricity from Ocean Waves

CNN has reported that a Scottish company has set four machines off the Portuguese coast and that these machines can generate electricity by the ocean waves. The four machines will generate 2.25 megawatts of power at a cost of nine million euros, which is a little pricey, but as more of these machines come on line, economies of scale should take over rather quickly.

This would be a completely renewable resource, and with 25 machines in place could reduce carbon emissions by about 60,000 tons. A fully deployed set of machines would reduce CO2 by about 1 to 2 billion tons each year.

Including the environmental pollution reductions in the costs of this new resource should make the marginal cost of generating electricity much closer to traditional means, such as burning coal.
