Tidal and Wave Power Full of Promise in Scotland

by Erin Larsen

In the northeast-most corner of Scotland sits the future site of the world’s largest array of tidal turbines, undersea windmills turned by the waters. As the race to develop alternatives to fossil fuels continues to accelerate, ocean energy is a clean-tech holy grail. Now, with Scotland’s estimated $1.5 billion MeyGen turbine project under way, the promise of tidal energy has never been closer.

Once all the undersea cables are laid, substations are built, and 269 turbines are put in place, MeyGen will have a production capacity of 400 megawatts of power – enough to power 175,000 homes. The project is being overseen by Atlantis Resources. Continue reading

Mobile Energy: Moving Power Sources Offshore

by Sharon Ha

A recent Greentech Media article outlines the worldwide trend of mobile energy plants being moved into the ocean. Author Julia Pyper surveys energy initiatives regarding mobile power plants across the globe, including China, Russia, Japan, U.S., and Norway. Much of construction will be completed soon, by late 2010s or early 2020s. Pyper also examines the pros and cons of each policy, noting how benefits differ depending on the type of energy plant. Also, these plants are expected to be less harmful to the environment than onshore plants, take up less livable space, and are cheaper to maintain. However, it will be hard to find staff and equipment for these floating devices, and radioactive substances could potentially contaminate the surrounding areas. Continue reading
