At PNNL, we believe that greater energy efficiency throughout buildings, improved technologies for enabling renewables – such as wind, water, solar, and biomass – and new vehicle technology, including storage systems for electric vehicles, can lead to timely solutions to our nation's energy challenges. We are a team of chemical, environmental, and materials scientists, economists, and engineers who are finding more efficient ways to use energy resources in transportation, buildings, and industry, and advancing clean, renewable energy.

Buildings account for 40 percent of energy consumption in the United States – more than any other sector in our economy. Residential and commercial buildings use energy daily for heating and cooling, lighting and water, and to run appliances and electronics. Much of this energy comes from burning coal or natural gas, which releases carbon dioxide – the most abundant of greenhouse gases – into the atmosphere. Automobiles present similar issues, but with a variety of alternative fuels and advancing vehicle technologies, they are creating less greenhouse gas emissions and reducing our dependence on foreign oils. PNNL's expertise in bioenergy, including catalysis for bio-diesel and jet fuels, has led to cleaner exhaust, petroleum alternatives, and the advancement of the transportation industry.

Our science base is also the foundation of a long history addressing national challenges in renewable energy. For example, PNNL leadership in science and engineering for sustainable hydropower in the Pacific Northwest is leading to increased fish passage safety and optimized hydroelectric power plants that can be applied at the national scale. Efficient and environmentally friendly energy generation is essential for meeting the demands of a growing consumer base.

    Transactive Times: Three PNNL Researchers Featured in Special Issue

    The May/June 2016 issue of IEEE's Power & Energy Magazine focuses on a topic that the grid gurus at PNNL hold dear: transactive energy. Three of PNNL's own leaders in the transactive energy continuum are featured in the issue, which may help demystify transactive energy and put it on the map as a novel approach for energy management.
