LPG: An Assessment of Alternative Fuels
In his State of the Union Address for 2007, President George W. Bush called for a 22% increase in federal grants for research and development of alternative energy. The NREL’s raison d’etre is the advancing of the US Department of Energy’s and the United States’ alternative energy objectives.
The laboratory’s field researchers and staff scientists, in the words of Laboratory Director Dan Arvizu, support critical market objectives to accelerate research from scientific innovations to market-viable solutions. At the core of this strategic direction are NREL’s research and technology development areas. It spearheads research and development efforts into renewable sources of electricity; these would include such things as solar power, wind power, biomass power, and geothermal power.It also spearheads research and development of renewable fuels for powering our vehicles such as biomass and biodiesel fuels and hydrogen fuel cells.
