A Sea Of Green Power Beneath The Waves? Tidal Electricity Is Becoming A Reality Off The Coast Of Wales

December 01, 2016
Britain’s coast is way more than white cliffs, cold beaches and crisps-stealing seagulls. It also boasts some of the highest tidal ranges in the world, measuring between 23 and 40 feet. Twice a day, like clockwork, the moon’s gravity makes the seas ebb and flow. All that moving water is also a huge reservoir of reliable, renewable and carbon-free electricity. “Tidal could potentially supply up to 12 percent of the U.K.'s energy generation,” says Mark Elborne, president and CEO of GE UK.

How Renewable Energy Is Taking A Page From Bitcoin

Laurent Schmitt Smart Grid Strategy Leader GE Grid Solutions
November 28, 2016

The problem of “too much” renewable energy on a grid can be solved with blockchain, a technology most often associated with bitcoins. Blockchain will provide a transparent way for households and businesses to trade renewables with each other. Laurent Schmitt, Smart Grid Strategy Leader for GE's Grid Solutions business, explains how it will work.

 

 

Bitcoin is one of the most revolutionary ideas to come out of the tech world. A whole new form of currency was created from nothing, but people are now using it to buy everything from coffee to electronics.

Hawaii’s Biggest Electricity Supplier Explains How The State Will Be First To Rely On 100 Percent Renewables

Connie Lau
November 18, 2016
What’s been called the most aggressive clean energy goal in the nation, legislation was enacted last year with the goal that the state of Hawaii will use 100 percent renewable sources by 2045. Connie Lau, president and CEO of Hawaiian Electric Industries Inc., and GE Ecomagination Advisory Board member, explains why the state’s largest electricity supplier supports the goal and what they are learning as they work to get there.

    High Voltage: Watch Out AC / DC Is Getting Its Groove Back

    Dorothy Pomerantz
    November 02, 2016
    America’s largest machine — the power grid — has been pumping lifeblood electricity from power plants to our homes and businesses for more than a century. The vast network of wires, switches, transformers and other technology has gone through periodic upgrades, but the infrastructure is aging and increasingly prone to blackouts. Unfortunately, the stress on the network is starting to show at exactly the time when we need it to shoulder and move thousands of megawatts from new wind farms and solar installations popping up all over the country.

    This Unique Combo Of Wind And Hydro Power Could Revolutionize Renewable Energy

    Tobey Grumet
    October 16, 2016
    Wind is a clean, cheap source of renewable energy, but it’s also fickle. You can never be sure whether the wind will blow. But engineers in Europe have now found a way to crack this shortcoming by combining it with hydropower. The big idea here is that the wind will generate electricity when it’s, well, windy, and the water will act as a giant battery that will discharge and modulate output when it stops blowing.

    Bladerunners: GE’s Wind Business To Buy Danish Blade Maker For $1.65 Billion

    October 11, 2016
    The company that made the world’s largest wind turbine blade will soon join one of the world’s largest makers of wind turbines. GE said today that it plans to acquire LM Wind Power, the Danish maker of rotor blades, for $1.65 billion.
    LM Wind is a global leader in wind turbine rotor manufacturing. The company builds blades for the industry’s 1.5- and 2-megawatt, meat-and-potatoes wind turbines as well as 8-megawatt behemoths with rotors spanning 180 meters — more than two football fields.

    Thousand Power Islands: These Technologies Will Help Turn On The Lights In Remote Parts Of Indonesia

    September 22, 2016
    From Jakarta’s glittering glass towers—which seem to grow as fast as rattan—to remote fishing villages with no plumbing and electricity, Indonesia is a country of contrasts. Spread across some 18,000 islands—only half of which have been named—its megacities and lush green forests are home to some 255 million people, making it the fourth most populous country in the world after India, China and the United States. The government is now trying to make sure the vast majority of them can turn the lights on at night.

    Turnt4Turbines: Top Photogs Shoot Block Island Wind Farm

    September 20, 2016
    It’s the last week of summer. Sunset. You’re 3 miles out to sea, 500 feet above the churning waves in a little red helicopter with (you hope) a trusty seatbelt and no door.
    Roughly at eye level, a white blade traces a sinuous line across the sky to the nacelle that holds the gears of an offshore wind turbine.

    Grip your camera, lean out (but not too far, bucko!) and train it on the turbine backlit by a fiery sun. Find the turbine’s reflection in the aircraft’s tail. Snap.

    Solar Has Big Limitations, But This Wonder Material May Change That

    Jeffrey Carbeck
    September 14, 2016

    Three years ago, Oxford University physicist Henry Snaith, one of the earliest researchers of perovskite, said that material would usher in a "new era for low-cost, high-efficiency" solar cells. This year, it's one of the World Economic Forum's top 10 emerging technologies. Jeffrey Carbeck, a specialist leader in advanced materials with Deloitte, discusses the strengths that perovskite may have over silicon photovoltaic cells for solar use.
