Even before a single ounce of natural gas gets burned in a home or power plant, massive amounts of CO2 have already been released. The process of extracting natural gas releases carbon dioxide pent up in the same wells as the gas, thus adding to the climate-changing impact of the fuel.

To help lower the global warming impact of one of the world's largest natural gas fields, General Electric has supplied Chevron, Exxon Mobile and Shell with enough compression "trains"--the pumps and turbines that do the sequestering--to create the world's largest carbon sequestration project. The trains will pump 3.3 million tons of CO2 released from natural gas mining back into the ground every year. That's the equivalent of taking 630,000 cars off the road.

A Maui resort community is slated for a new smart grid, courtesy of General Electric. The power grid will cut back energy costs by automatically turning off household appliances when electricity prices soar, and aims for the 2012 goal of reducing peak electricity consumption by 15 percent.

The community of Wailea will see new power meters in homes that help monitor electricity usage among different appliances, according to AP. Part of the project also involves upgrading utility computers so that they can better integrate renewable energy from more unpredictable sources such as solar and wind.

Today, General Electric unveiled a next-generation optical storage technology that can pack as much as 20 Blu-Ray discs or a hundred DVDs' worth of data onto a single disc. The newly devised discs, which use holograms to store data in the form of bits, can hold 500 gigabytes of information, the company says.

They sit on a spur of test track outside General Electric’s locomotive factory in Erie, Pennsylvania, panting and grumbling like two old lions half asleep. The ominous, muttering rumble is the sound of 8,800 horsepower at idle—24 cylinders with pistons big as buckets, turbochargers the size of washing machines, two V12 engines direct-driving alternators five feet in diameter.
