lbs of CO2 abated

Cost
Impact: CO2

We’ve abated enough CO2
to offset more than 20,000
cross-country flights.

  • Thumb

    We've abated enough CO2 to offset all the energy used in a year by Afghanistan and the Cayman Islands together

  • Car

    We've taken the equivalent of more than 200,000 cars off the road

  • Leaf

    We've effectively added 12,000 acres of rainforest (which could sequester as much CO2 as we've abated)

    Reports Boost Other Utility Program Participation

We use a well-defined, scientific approach to measurement and verification.

Opower’s methodology and results have been independently verified by leading industry analysts and non-profit organizations, including the American Council for an Energy-Efficient Economy (ACEEE), The Brattle Group, Navigant Consulting, Power Systems Engineering, KEMA, Environmental Defense Fund (EDF), as well as by established academics from several leading institutions. Our measurement protocols follow guidelines specified by Public Utility Commissions across the country, and in particular the protocols laid out in the California Public Utility Commission’s Measurement & Verification Guidelines and the EPA’s National Action Plan for Energy Efficiency (NAPEE) guidelines.

  • Time Comparison

    We use baseline data to identify test and control groups with statistically equivalent usage patterns and histories.

  • Group Comparison

    We measure program impact against a group of non-participating homes to control for external factors that may affect energy use.

  • Replication

    We measure energy use across thousands of households, over different spans of time, to increase the statistical precision of our results.

  • Social Norms and Energy Conservation

    The first evaluation of a scaled behavioral efficiency program to be published in a peer-reviewed journal, authored by Hunt Allcott, Assistant Professor of Economics at New York University.

  • 30 Month SMUD Program Evaluation

    Independent verification of results from the first 30 months of Opower's deployment at Sacramento Municipal Utility District by Navigant Consulting. The report shows strong savings sustained over nearly three years.
