Watch here: Energy Secretary Steven Chu and Microsoft Founder and Chairman Bill Gates hold a fireside chat at the 2012 ARPA-E Energy Innovation Summit, where the two exchanged ideas about how small businesses and innovators can get off the ground successfully.

Biofuels produced here in the U.S. increase our energy security, but there is still a need for next-generation renewable fuels that can be integrated into the nation's current fuel refining and distribution infrastructure. If successful, electrofuels projects sponsored by ARPA-E could help fill this void.

Can you imagine a world in which the pace and scale of innovation of the last 100 years is replicated and compressed into the next 10 to 20 years?

ARPA-E recently announced 60 cutting-edge research projects across five programs, and aim to dramatically improve how the U.S. uses and produces energy. Read more about these new programs and how each takes a unique approach to “out-of-the-box” transformational energy research.

Read about the Liquid Metal Battery -- an innovative emerging technology comprised of liquid metal electrodes of differing densities, which allows the liquids to separate and stratify without the need for any solid separator.

To create jobs and lead in the global clean energy economy, the Obama Administration has made a point of supporting game-changing innovations – including the Energy Department’s Advance Research Programs Agency for Energy (ARPA-E).

The world is offering possibly the biggest economic opportunity of the 21st century. The question is: Can we grab it? Dr. Arun Majumdar gives us his take.

Investments in Primus Power's low-cost, distributed storage battery technology pave the way for increased integration of solar and wind technology into our nation's energy portfolio.

How do people make decisions about energy? What compels their behavior? And how can energy be used more efficiently without adversely affecting people’s lifestyles? ARPA-E's project is seeking a breakthrough on the human behavioral side of energy use, which will be used for public websites and data to reduce energy use.

Find out how this partnership will take early stage technologies out of the lab and test them to see if they can revolutionize the way we use and store electricity.

An inside look at 1366 Technologies' innovative approach to solar manufacturing. Documenting how a $4 million grant from the Advanced Research Projects Agency-Energy (ARPA-E), through the Recovery Act is helping to make their ambitious goal of producing “solar at the cost of coal” a reality.

A new project is using thermophilic extremophiles -- microorganisms that grow optimally in temperatures above 160 deg F -- to produce a new highly efficient fuel. Learn more.
