Department of Energy
Secretary Steven Chu
Budget: 27.2 billion dollars
The Department of Energy's job is to address energy and environmental challenenges, such as global warming or nuclear power, by creating and promoting new technology. One thing they do is help promote electric cars by adding charging stations. Another is to enhance nuclear security through nonproliferation and defense, and another is to make renewable energy sources, like solar, wind, and geothermal energy.
If i were in charge of the department of energy, I would increase its budget, because getting stuff like solar energy and electric cars is important so we don't destroy the earth with poloution and global warming.
