Energy content of biofuel (J/kg) or equivalent units. Energy density is the amount of energy stored in a fuel per unit volume, expressed in SI units as joule per litre (J/L) or equivalent units. The table below includes entries for popular substances already used for their energy, or being discussed for such use. The second column shows specific energy, the energy content in megajoules per unit of mass in kilograms, useful in understanding the energy that can be extracted from the fuel. The third column in the table lists energy density, the energy content per liter of volume, which is useful for understanding the
National Energy Research Scientific Computing Center National Energy Research Scientific Computing Center The National Energy Research Scientific Computing Center, or NERSC, is a high performance computing (supercomputer) user facility operated by Lawrence Berkeley National Laboratory for the United States Department of Energy Office of Science. As the mission computing center for the Office of Science, NERSC houses high performance computing and data systems used by 7,000 scientists at national laboratories and universities around the country. NERSC's newest and largest supercomputer is Cori, which was ranked 5th on the TOP500 list of world's fastest supercomputers in November 2016. NERSC is located on the main Berkeley Lab campus
