4,000: The DOE’s estimate of the dollar cost for a battery delivering 40 miles of electric range (in a plug-in hybrid, for example) in 2015, compared to an estimated $6,700 in 2013 and more than $13,000 in 2009.

5,000: The number of charging stations that Coulomb Technologies plans to deploy at residential and commercial locations in nine metro areas using a $15 million stimulus grant.

10,000: The DOE’s estimate of the dollar cost for the battery needed to give an electric car 100 miles of range by the end of 2015, compared to an estimated $16,000 in 2013 and $33,000 in 2009.

20,000+: The number of new electric vehicle charging stations expected to be available in the U.S. at residential, commercial and public locations by December 2013.

80 million: Number of additional square meters of separator materials for lithium-ion batteries that Celgard will be able to produce at its plant in North Carolina each year following completion of a factory expansion supported with a $49.2 million DOE grant.

5 billion: Amount in dollars that the DOE is investing in electric vehicle batteries, components, charging infrastructure and other efforts to “electrify America’s transportation sector” through the Recovery Act and the Advanced Technology Vehicles Manufacturing loan program.

Here's more info on what the Federal Gov. is doing to save energy.

Consider this: altogether federal, state, and local government constitute more than 38 percent of our GDP. Allow that to sink in for a moment. The federal government will spend $3.6 trillion this year. In more concrete terms, Uncle Sam owns or leases more than 430,000 buildings (mostly large office buildings) and 650,000 vehicles. The federal government is the world's largest consumer of energy and vehicles, and the nation's largest greenhouse gas emitter. Add state and local government activity, and all those numbers grow by about a third again.

The good news is that despite our sclerotic, largely right-wing Congress, government agencies are turning toward procurement as a means to jump-start clean tech and cut emissions.

Perhaps the most important move in this direction came in October 2009, when President Obama quietly signed Executive Order 13514, which directs all federal agencies to "increase energy efficiency; measure, report, and reduce their greenhouse gas emissions from direct and indirect activities; conserve and protect water resources through efficiency, reuse, and stormwater management; eliminate waste, recycle, and prevent pollution; leverage agency acquisitions to foster markets for sustainable technologies and environmentally preferable materials, products, and services; design, construct, maintain, and operate high performance sustainable buildings in sustainable locations."

The executive order also stipulates that federal agencies immediately start purchasing 95 percent through green certified programs and achieve a 28 percent greenhouse gas reduction by 2020. The stimulus package passed in 2009 included $32.7 billion for the Energy Department to tackle climate change, and some of that money is now being dispersed to business and federal agencies.

However, back on Planet America the asphalt transportation arteries are clogged with 250 million gasoline-powered vehicles sucking down an annual $200-300 billion worth of fuel from more than 121,000 filling stations. Add to that the cost of heating and cooling buildings, jet travel, shipping, powering industry, and the energy-gobbling servers and mainframes that are the Internet, and the U.S. energy economy reaches a spectacular annual tab of $2-3 trillion.
