(PhysOrg.com) -- Using solar panels, wind turbines, appliance monitoring, and on-site energy storage, General Electric has a plan to enable homeowners to cut their annual energy consumption (from the electric grid) to zero, in some cases, and at least minimize consumption in others. GE is piloting the technology this year, and hopes to commercialize the system by 2015. http://www.physorg.com/news166965770.html Technology Thu, 16 Jul 2009 12:23:15 EST news166965770 (PhysOrg.com) -- A team of Yale University researchers has discovered a "repulsive" light force that can be used to control components on silicon microchips, meaning future nanodevices could be controlled by light rather than electricity. http://www.physorg.com/news166711942.html Physics Mon, 13 Jul 2009 13:52:50 EST news166711942 Top electricity distributor Manila Electric Co., better known as Meralco, plans to use its power lines to deliver broadband Internet service, a company statement has said. http://www.physorg.com/news166680504.html Technology Mon, 13 Jul 2009 05:09:36 EST news166680504 A research report in the International Journal of Environment and Pollution suggests that individuals prefer to be involved in a collective contribution to green electricity that involve everyone paying more, rather than having individual higher bills. http://www.physorg.com/news165739334.html Space & Earth Thu, 02 Jul 2009 08:20:02 EST news165739334 US software giant Microsoft launched a free online home energy monitoring tool on Wednesday that allows consumers to gauge their usage and reduce consumption. http://www.physorg.com/news165084939.html Technology Wed, 24 Jun 2009 18:30:01 EST news165084939 Steve and Beth Griffith and their family thought they were well on their way to living an energy-saving green lifestyle. http://www.physorg.com/news164919474.html Technology Mon, 22 Jun 2009 20:30:01 EST news164919474 Dreams of renewable energy riches have set off a scramble not seen since miners rushed into these surrounding hills in search of shiny nuggets. http://www.physorg.com/news162824347.html Technology Fri, 29 May 2009 14:00:02 EST news162824347 At "Laser 2009" in Munich, Germany, June 15 to 18, Fraunhofer researchers will be demonstrating how laser technology can contribute to optimizing the manufacturing costs and efficiency of solar cells. http://www.physorg.com/news162814613.html Technology Fri, 29 May 2009 11:19:40 EST news162814613 (AP) -- The organizers of a global business summit on climate change say millions of new jobs would be created in the U.S. alone by relying almost entirely on renewable or low-carbon sources of electricity. http://www.physorg.com/news162447096.html Technology Mon, 25 May 2009 05:13:16 EST news162447096 (PhysOrg.com) -- Chip manufacturers beware: There's a newfound flaw in our understanding of transistor noise, a phenomenon affecting the electronic on-off switch that makes computer circuits possible.

When you have to plug in a car for a charge, the electricity used to charge the battery often comes from a power plant that gets its energy from oil. Chicago is hoping to change that as it becomes the first city to install an electric vehicle (EV) charging station powered with solar energy. http://www.physorg.com/news158564122.html Technology Fri, 10 Apr 2009 06:36:09 EST news158564122 Chinese and Russian cyber-spies have hacked into the US electricity grid and inserted programs that could be used to disrupt the system, a report said Wednesday. http://www.physorg.com/news158409303.html Technology Wed, 08 Apr 2009 11:35:26 EST news158409303 Australia announced plans to build a 30 billion US dollar broadband network, its biggest infrastructure project ever, opting to retain government control rather than contract out the deal. http://www.physorg.com/news158302467.html Technology Tue, 07 Apr 2009 05:55:01 EST news158302467 Dear EarthTalk: If you have an electric or plug-in hybrid car, you're paying for electricity rather than gasoline all or most of the time. How does that cost compare to a gas-powered car's cost-per-mile? And since the electricity may be generated from some other polluting source, does it really work out to be better for the environment?
