Of all the opponents of wind turbines , few are as vociferous as the loose collective that planners and developers deride as “Nimby,” a term that derives from the acronym for “not in my backyard.” Driven to stake out real estate further offshore, a group of European companies have devised a plan almost breathtaking in its audacity: create a vast artificial island in the middle of the tumultuous North Sea, populate the area around it with thousands of spinning pylons, and drum up enough renewable energy for millions of Europeans by 2050. The venture, born of the 2050 goals laid out by the Paris agreement on climate change , is a collaboration between Denmark’s Energinet and the German and Dutch arms of electricity firm TenneT . To solidify the partnership, the companies will be meeting with Maroš Šef?ovi?, the European Commissioner for Energy, at the North Seas Energy Forum in Brussels next week to sign a trilateral agreement. If greenlit, the proposed 2.5-square-mile Power Link Island, also known as the North Sea Wind Power Hub, will boast its own harbor, air strip, solar farm, and artificial lake, along with homes for in-residence staff. Early estimates place the price of construction in the ball park of $1.3 billion. Dogger Bank, a large sandbank about 62 miles off the east coast of England, is thought to be the ideal location for the island because it’s centrally located, has waters shallow enough for turbines, and is buffeted by constant wind.

By linking the energy markets of those countries, Power Link Island could facilitate international trading in electricity. It could even consolidate energy by serving as a connective hub for other, scattered wind farms or bud off smaller but similar enclaves. “This project can significantly contribute to a completely renewable supply of electricity in Northwest Europe,” said Mel Kroon, CEO of TenneT. There’s another upside: An island of significant scope could, through economies of scale, also whittle down costs. “Offshore wind has in recent years proved to be increasingly competitive and it is important to us to constantly focus on further reduction in prices of grid connections and interconnections,” said Peder Østermark Andreasen, CEO of Energinet. “We need innovative and large-scale projects so that offshore wind can play an even bigger part in our future energy supply.” + Energinet + TenneT Via The Next Web
For the first time in nearly a century, a ship is about to be fitted with a set of “spinning sails” that harness the wind to help power it across the ocean—a technology that could significantly green up the process of trans-oceanic shipping. As The Guardian reports, the spinning or rotor sail was first invented in 1926 by German engineer Anton Flettner, who installed them on two ships, including one that crossed the Atlantic. The “sails” are actually rotating columns that work with the prevailing winds to generate forward thrust for ships. This modern trial of a new take on old technology is backed by Maersk, Shell ’s shipping arm and one of the largest shipping companies in the world. One Maersk tanker ship will be outfitted with two of the nearly 100-foot-tall spinning sails – which are manufactured by Finland’s Norsepower . How, exactly, do they work? The spinning sails employ a principle known as the Magnus effect , in which wind passing through the spinning rotor sail accelerates on one side, while decelerating on the other. The movement of the sail generates a “thrust force” perpendicular to the wind. Electricity from the ship powers the turning of the sails, and the force generated by the sails lets the ship’s engine throttle back to lower fuel consumption. Using these sails could theoretically cut the fuel consumption of global shipping by as much as 10 percent. Related: Wind energy supplied all of Denmark’s power needs in one day Add to that the fact that, when the winds are right, each of these sails can produce about 3 megawatts of power while only requiring 50 kilowatts to operate, and the ships also have a source of renewable energy on board. The rotor sail only failed during its first go-around in the 1920s because it couldn’t compete with diesel power at that time. Now, as the price of fossil fuels is on the rise and climate change is here, this technology could be ready to set sail. Via The Guardian Images via Norsepower

Comments Off on Why Sun Chemical sees solar as part of its cost-reduction strategy
Schneider Electric, the global specialist in energy management and automation, recently added another healthy dose of renewable energy to its portfolio.The company has announced the signing of a 20-year solar power purchase agreement (PPA) that will allow its client, Sun Chemical, to cut electricity costs at its Carlstadt, N.J., production facility by roughly $400,000. This extends the energy savings the company has realized through its partnership with Schneider, which runs into the millions.

Comments Off on Amazon to install large-scale solar systems on 50 facilities by 2020
Amazon just announced plans to install 41 megawatts worth of solar power on the roofs of its US facilities this year. The project is part of amazon’s larger initiative to install solar systems on 50 of its order fulfillment facilities around the globe by 2020. “As our fulfillment network continues to expand, we want to help generate more renewable energy at both existing and new facilities around the world in partnership with community and business leaders,” said Dave Clark, Senior Vice President of Worldwide Operations. “We are putting our scale and inventive culture to work on sustainability—this is good for the environment, our business and our customers. By diversifying our energy portfolio, we can keep business costs low and pass along further savings to customers. It’s a win-win.” The solar projects planned for this year will see a total of 41 megawatts installed on the rooftops of Amazon facilities in California, New Jersey, Maryland, Nevada and Delaware. Depending on various factors, the solar installations could provide the facilities with up to 80% of the energy needed to run.

It’s also possible some of this power could be used to energize other initiatives Amazon is working on – such as the eventual delivery of orders by drones , and the company’s plans to build a giant floating warehouse in the sky from which the drones would work.
