Times They Are a-Changin': The Renewable Energy Transition Is Happening, But Major Challenges Are Slowing It Down

Christine Lins Executive Secretary Ren21
June 05, 2016

Countries, provinces, cities and companies are increasing their renewable energy production targets at a rate that makes clear the transition away from fossil fuels is happening and unstoppable. But they must overcome major structural, political and perception hurdles if they hope to attain a future powered only by renewable sources.

The Temple Of Turbine: One of These Wind Turbines Can Power 5,000 Homes

The French port of Saint-Nazaire lines the northern shore of the Loire estuary as the river empties its muddy waters into the Atlantic Ocean. The city may not be large, but the 70,000 people who live there are used to making very big things.
The world’s fastest and largest liners, including Normandie and Queen Mary 2, sprung from its dry docks. The port also serves as a transit hub for the fuselage and wings that make the double-decker Airbus A380, the world’s largest passenger aircraft.

This Massive Magnet Will Generate Power At America's First Offshore Windfarm

Tomas Kellner
March 20, 2016
Offshore wind farms can tap into a bounty of wind that allows them to work twice as productively. But that efficiency comes at a cost. Like any sea-based technology, wind farms are difficult to build and expensive to maintain, with workers fighting against the same weather that makes the farms work so well. As a result, terrestrial turbines have been steadily gaining ground compared to turbines built at sea. But that may soon change.

How GE Is Helping Build America’s 1st Offshore Wind Farm

Timothy Brown
March 18, 2016
New wind farms added more than a quarter of total new power generation capacity in the United States between 2010 and 2014, reaching 75,000 megawatts at the end of last year. No other country with the exception of China has more. But the race is on.

Mix And Match: These Engineers Make Renewables Play Nice With Other Sources Of Energy

Tomas Kellner
March 10, 2016
New solar and wind energy farms added a whopping 68 percent of new power generation capacity in the United States last year, according to a report from Bloomberg New Energy Finance. When combined with hydropower, renewables now make up a fifth of America’s electricity generation capacity, more than double what it was in 2008.

This trend isn't going away. Getting all that clean electricity to homes and factories, however, is a challenging task.

This Scientist Has Turned The Tables On Greenhouse Gas, Using CO2 To Generate Electricity

March 07, 2016

Solar power is a great source of renewable energy, but as with many things in life, timing is everything. The sun doesn’t shine on long winter nights when people turn on their lights. On the other hand, a sunny Sunday afternoon can produce an ample electricity surplus that’s difficult to store.

“That’s the grand challenge,” says Stephen Sanborn, senior engineer and principal investigator at GE Global Research (GRC). “We need to make renewable energy available to the grid when it is needed.”

Cloudy With A Chance Of Electrons: This Scientist Can Forecast Renewable Electricity

Todd Alhart
February 29, 2016
A group of physicists that included a Nobel laureate and Kurt Vonnegut Jr.’s brother spent the 1940s working in GE labs to figure out how to control the weather. After a promising start – they created snowfall over Schenectady, N.Y. – the project eventually fizzled.

The Electron’s Digital Journey: Do You Know Where Your Power Comes From?

Tomas Kellner
February 22, 2016
The electrons that brew your first cup of coffee in the morning have many different parents. Some were born on a wind farm, while others came from a gas-fired power plant or a water turbine buried deep inside a massive dam.
