three Princeton properties doing their part to reduce fossil fuel consumption by measuring their real-time electricity use. 

Use our Energy Pyramid to guide you through the steps you can take to use less electricity, save money on your utility bills and help Princeton reduce its greenhouse gas emissions. You can also get started right away by scheduling an energy audit with Tri-State Light & Energy, Inc., Mercer County's designated Direct Install contractor.
