Washington, DC
Despite urgent calls from the White House and members of Congress this year about the need for more energy R&D, government funding for energy research is expected to stagnate in 2011 and possibly even decrease in 2012.

Crumpled sheets of graphene.
New graphene ultracapacitors have five times the energy density of current commercial devices, thanks to the increased surface area of the "crumpled" graphene nanomaterial.

ice
Startup IceCode won GE's Ecomagination Challenge last month for a technology that instantly removes ice from wind turbines. Now they want to incorporate thin-film pulse electrothermal de-icing (PETD) into refrigerators, saving up to 35% of the energy used.

An ARM microprocessor made by Marvell.
In an effort to reduce the cost of cooling microprocessor chips, data centers are looking to low-power chips used in cell phones and other mobile devices. These chips can generate energy savings, but they also have less processing power, so they may only be used in specific systems or applications.

Thermostat
Co-generation of heat from coal power plants increases energy efficiency, but the resultant reliance on coal plants to supply heat limits the grid's use of renewable energy during cold months. As a result, some grid operators are building pumped hydro systems to store the un-used renewable energy.

Cogenra Solar's hybrid solar cell
Cogenra Solar has developed a hybrid solar array that produces electricity and uses waste heat to provide hot water. The company says it has a solution for the overheating problems that have stymied this type of hybrid solar in the past, and they also believe they can achieve reasonable efficiency.

white light LED
Startup EcoSpark believes it can produce a white light LED using zinc oxide. Unlike blue, gallium nitride LEDs, EcoSpark's bulb doesn't require any phosphorus coating to achieve white light, making the device cheaper and more efficient.
