Solar Electricity
UC Davis has a 16.3 megawatt on-campus solar farm that generates about 14% of the campus’s electricity needs and reduces the University's carbon footprint by 9%.
About 30% of UC Davis' purchased electricity comes from two large off-site solar PV farms in California.

Grid Electricity
The campus purchases electricity from the grid to
supplement its electricity needs.

Large Hydropower
UC Davis has a contract with Western Area Power Administration to purchase electricity generated from large-scale hydro-power sources. The electricity is not considered "renewable" under common definitions, but it is 100% Carbon Neutral.

Natural Gas
The campus purchases natural gas delivered through
PG&E pipe lines to heat campus buildings and make hot
water.
