Where is the grid going, big or small?

Scientists at Pennsylvania State University have discovered a solution to the problem of reliable storage for alternative energy: a bacteria that can convert electricity to methane when combined with CO2.

Any surplus power from wind, solar, or tidal sources is fed into the bacteria and combined with CO2 from the atmosphere to create methane for storage. Methane is a clean-burning gas and 80% of energy fed into the process was retained at the end.

Legacy electricity grids, the current distribution systems used for a century in the US, are highly inefficient…7%, never makes it to the user, lost at the transmission and distribution levels…..Environmentalists and others have been pushing for smart-grid technology for over a decade because it will enable consumers to use less electricity and benefit the environment.

Spending in the American Recovery and Reinvestment Act on environmental projects being debated in Congress right now already includes $100 billion in ‘green stimulus.’ But because of the stated preference for so-called ’shovel-ready’ infrastructure projects, long-term infrastructure projects like mass transit and a smart grid may suffer.

PG&E may be installing millions of smart meters in Northern California, but the nation of Malta (pop. 400,000) is about to become the world’s first smart grid island. IBM is building the island’s national smart grid network, which will consist of 250,000 smart meters placed in homes around the country.

GreenSmith Energy Management Systems has unveiled technology it claims can solve the peak demand issues experienced by U.S. utilities.

The company has created a battery control-management system, that when paired with a lithium ion battery, can store up to 20 kilowatt-hours. The system can then deliver a full 4,000 discharge cycles.

European Union officials are studying plans for an international wind power grid in the North Sea that could provide energy generated from renewable sources to 70 million European homes. The proposed offshore grid would be more than 3850 miles long, and connect more than 100 wind farms, containing a total of 10,000 turbines to seven countries.

I have been living off the grid for 15 years now, and there are certain parts of my daily energy use practices I take for granted as normal. Yet, when I visit friends or relatives living on the grid, I become aware of how differently I use electricity. While watching last week’s PBS NOW program about families living off the grid in Iowa, I began to wonder if the principles of

Global warming concerns, government policies, and money-saving efficiency benefits have spurred clean energy systems to spring up all over the world. But a giant wind farm in the middle-of-nowhere North Dakota doesn’t do much good if there aren’t transmission lines to connect the power with the more populated areas that need it.

Europeans are facing similar distribution and reliability issues with their burgeoning renewable energy growth, and some see a continent-wide grid as

The Western Area Power Administration (WAPA) is responsible for delivering hydroelectric power within a 15-state region of the central and western United States. WAPA – an agency of the U.S. Department of Energy – has a transmission system that carries electricity from 57 power plants to homes and businesses across a great portion of this country.

Stifle that yawn! The exciting news is that its new administrator is gung-ho on wind power.
