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.

This Data Will Blow You Away: Renewables By Far The Largest New Power Source In The U.S.

Tomas Kellner
February 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.

Christine Todd Whitman: What’s the Most Effective Path to Clean Energy? Go Nuclear

Christine Todd Whitman President Of The Whitman Strategy Group
February 09, 2016

Overlooking nuclear energy as part of America’s clean energy strategy would be tantamount to unilateral disarmament.

Clean, green and reliable — these should be the core elements of our nation’s energy policy in the 21st century and beyond. Accepting any lesser criteria will hinder our efforts to reduce carbon pollution and provide clean air for all Americans to breathe. That’s why we cannot afford to lose the most important tool in our clean energy arsenal: carbon-free nuclear energy.

Mind The Gap: Here’s How You Take On A Power Crisis The Size Of A Continent

Tomas Kellner
January 06, 2016
One easy way to see Africa’s power problem is by looking at a picture of the Earth from space at night. While other inhabited regions of the world glow and sparkle like jewels in a black velvet display case, Africa remains largely dark. That’s because the continent’s 1.1 billion inhabitants have at their disposal just 185 gigawatts (GW) of installed power-generation capacity. The United States, by comparison, can draw on 1,000 GW for 300 million people.

The Real Point Break: Where The World’s Largest Gas Turbines Prove Their Mettle

December 15, 2015
In parts of the world like the US and Brazil where electric current oscillates at 60 Hz, there’s no larger and more efficient gas turbine than a machine GE calls 7HA. So efficient, in fact, that when it swallows and burns 3.3 tons of air mixed with natural gas - equivalent to 23 tanker trucks - out comes a mere 6.3 fluid ounces of pollution, a volume slightly larger than a half- can of soda.

Go with Current: GE's New Energy Business Changes the Power Game

October 07, 2015
GE announced today the creation of Current, a startup that combines energy hardware with a digital backbone to make power simpler and more efficient for customers.
The company, which is backed by GE’s balance sheet, brings together GE’s LED, Solar, Energy Storage and Electric Vehicle businesses as a one-stop shop for early customers like Walgreens, JPMorgan Chase, Hilton Worldwide and others.

Something New Under the Sun: GE’s Industrial Grade Inverter Takes Solar Power to a New High

Tomas Kellner
September 10, 2015
Try as he might, Vlatko Vlatkovic won’t make the sun shine brighter. So when he wanted to make a more efficient solar farm, he and his team had to go for the next best thing: a gray plastic box the size of a small hut called the inverter. “It takes direct current from the PV panels and turns it into alternating current that you can use,” says Vlatkovic, chief engineering officer at GE Power Conversion. “Since the inverter system also represents as much as 20 percent of the capital costs of the farm, you could make a huge impact if you made it more efficient.”

Rise and Shine: This Diamond-like Material is Helping Solar Power Cast a Bigger Shadow

July 28, 2015
The energy usage curves of most industrial countries – or load curves - have long resembled a crumpled fedora hat. They rise sharply at daybreak as people start brewing coffee and companies switch on machines, then peak twice – in the morning and the late afternoon, before dropping off after dinner. Utilities usually crank up their turbines and bring extra power plants online to cover the “peak” demand.

Das Hybrid-Kraftwerk: Power Plant Mixing Gas, Solar, Batteries and Software Could Chart the Future of Renewable Power

May 13, 2015
From Japan’s offshore solar plants to a tidal lagoon in Wales, countries around the world have found clever ways to tap renewable power. But nowhere is the need for ingenuity more in demand than in Germany, which aims to produce 80 percent of electricity from renewables by 2050, up from 30 percent now.
