In the most rigorous analyses undertaken to date, two recently released resource assessments show that waves and tidal currents off the nation's coasts contain enough energy to provide a significant portion our nation’s total annual electricity usage.

For many, a barrel of oil is almost synonymous with its most prominent product, gasoline. While almost 40% of a barrel of oil is used to produce gasoline, the rest is used to produce a host of products including jet fuel and plastics and many industrial chemicals. As the United States works to reduce its dependence on foreign oil, we must recognize the complexity of that dependence and work to replace the whole barrel.

Teams at two of the Energy Department's laboratories are making headway on two projects that will enable building a new lithium battery that charges faster, lasts longer, runs more safely, and might also arrive on the market in the not-too-distant future. Learn more.

These are exciting times for fusion energy. Today I’m sharing that excitement with several hundred scientists at a conference on Inertial Fusion Science Applications in Bordeaux, France. These scientists, along with scientists and others around the world, have shown great interest in our National Ignition Facility (NIF) at Lawrence Livermore National Lab,

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.

Earlier this week, the Congressional Budget Office issued a new report that highlights the important role a clean energy standard could have in creating the clean energy jobs of the future at minimal cost to consumers.
 
The report evaluates several proposed clean and renewable energy standards, running them through a variety of models to deter

Entrepreneurs from Durham-based solar startup Semprius teamed with Governor Bev Purdue to announce the company’s plan to build a new high-tech manufacturing facility in Henderson. The factory is expected to create more than 250 full-time jobs over the next five years, which is a particular boon for Henderson, where the county unemployment rate reached 13.3% in May.

Pioneering startup Innovalight partnered with NREL to invent the first liquid silicon on the market. When paired with Innovalight’s industrial screen printing process, this silicon ink technology offers a novel path to producing solar cells with higher conversion efficiencies at lower cost.

The Energy Department announced $4.5 billion in conditional loan guarantees to three California photovoltaic solar power plants. Combined the projects will create enough energy to power 275,000 homes.

We anticipate the project will generate enough energy to power 31,000 homes.

Can you imagine a photovoltaic module that’s able to generate and store electricity on its own? Or an electric vehicle (EV) powered by a technology more durable than the advanced batteries in today’s EVs? Innovative solid-state nanocapacitors are making this clean technology possible.

Did you know 50 percent of the energy generated annually from all sources is lost as waste heat? What scientists are doing to take advantage of this opportunity to save money and new developments in harvesting fuel through photosynthesis.
