USDA: GREEN ENGINEERS

Multi-university $3.2M collaboration led by Dr .Heidi Taboada (PI)

and Dr. Jose Espiritu to to produce more scientists and

engineers who can develop new alternative energy sources and

ways to increase energy efficiency.

Offering in the spring semester a course for senior and graduate

students on “Energy Sustainability” as an introduction to the

different types of energy sources; carbon emissions and other

environmental impacts; electric power grid and the future smart

grid.

The course has a final project where the students propose a

device or a system to better exploit energy sources.
