PG&E Agrees to Buy Power from Canadian Firm’s Proposed ‘Wave Park’

Ocean waves pack immense energy in a small area. Tapping even a fraction of it could provide large amounts of electricity without pumping greenhouse gases into the air. And because the energy is so concentrated, the machines needed to tap it, in theory, don’t have be as big as a wind farm or a large-scale solar plant.
As a result, wave power could one day be cheaper than those other energy technologies.
“Wind and solar are very diffuse sources – you have to cover a lot of area to collect energy,” said Roger Bedard, leader of ocean energy studies at the Electric Power Research Institute. “Waves carry a lot of energy in a small space. Smaller machines cost less than bigger machines.”
