Harvard currently invests in renewable energy by installing and operating a number of on-site renewable energy projects, and purchasing renewable energy credits (RECs) to meet the requirements of the Massachusetts Renewable Portfolio Standard. To date, Harvard's Schools and administrative departments have installed a number of renewable and alternative energy systems including solar photovoltaics, and ground source heat pumps.

  • Biodiesel: 20% soybean oil, 80% diesel mix used in 75 diesel fuel vehicles including shuttles.​
  • Biomass: Waste wood is burned for heat at the Harvard Forest.
  • GreenRev: Program uses human energy to produce electricity (spin class bicycles tied to generators which are tied back to the building grid) at Harvard Business School's Shad Hall.
  • Heat recovery from the steam tunnels at Canaday Hall as part of solar and steam heat recovery system.

Renewable energy uses renewable sources of power (e.g. sun, wind). Alternative energy may still be fossil-fuel generated, but it uses the inputs more efficiently or recovers waste heat or energy (e.g. co-generation, waste wood burning, heat recovery).
