​​City residents, businesses and institutions spend over 200 mi​llion dollars per year on natural gas and electricity.  80% of our energy comes from coal.  Investing in energy efficiency and renewable energy are key to reducing climate-changing greenhouse gas (GHG) emissions and keeping millions of dollars in the local economy.

The City of Ann Arbor set GHG emissions reduction and renewable energy goals for municipal operations and the broader community. Ann Arbor recently adopted a Climate Action Plan that recommends three targets for community-wide greenhouse gas emissions reductions, all relative to a year 2000 emissions baseline:

  • Short-term target: reduce CO2e emissions 8% by 2015
  • Mid-term target: reduce CO2e emissions 25% by 2025
  • Long-term target: reduce CO2e emissions 90% by 2050

​The CAP identifies and quantifies 84 City actions to help Ann Arbor ​reach these goals. CAPMatrix.pdf

In 2011, Ann Arbor City Council adopted Ann Arbor's Green Energy Challenge, which also sets community and municipal goals:

  • 30% renewable energy for municipal operations by 2015
  • 5% renewable energy communitywide by 2015

Reaching these goals requires a lot of help for residents and businesses in the community.

Welcome to Ann Arbor Solarize

What:  Ann Arbor Solarize is a program with a simple design and a big impact.  We gather neighbors and friends together, along with pre-vetted solar installers, to learn about residential solar, get questions answered, and provide the option to come together to bulk purchase solar, allowing for significant savings.

Why:  Our whole reason for existing is to help facilitate MORE solar on MORE roofs and properties!  The benefits are robust for individuals, the community and the planet.  And NOW is the perfect time to consider solar.  The costs have come down, panel efficiency is better than ever, and there is a federal tax rebate of 26% that applies to all installations performed in 2020!  This tax credit reduces to 22% in 2021, and then it is gone.  In addition, legislation has recently passed in Lansing that eliminated the property tax increase associated with solar.  It’s an excellent time to jump in.

Who:  As part of the City of Ann Arbor’s A2Zero carbon neutrality work, the Ann Arbor Office of Sustainability and Innovations works with local and regional pre-vetted Solar Installers, as well as Michigan Saves, a non-profit green bank that facilitates low-interest financing for green upgrades, including solar installations.

How:  Our participating installers have all agreed to tiered discounts depending on the number of participants in a Solarize event.  These discounts are available because of savings realized by reduced advertising and outreach costs for the installers, and potential discounts they can realize by ordering in bulk as well. 


To learn more or to sign-up for your Solarize event, please contact the Ann Arbor Solarize program coordinator, Julie Roth, at or the OSI Manager, Missy Stults (, for more information.

We look forward to working with you!

Property Assessed ​Clean Energy (PACE) Program

Ann Arbor started the first PACE program in Michigan to help commercial property owners finance energy improvements through a special property assessment. The first round of PACE financing funded over $500,000 in local energy efficiency projects

LED Streetlights

Ann Arbor replaced 2,000 streetlight with LEDs to both cut energy and maintenance expenses, and to save energy

Greening Rental Housing

With over 50,000 Ann Arbor residents living in rental housing, the City is working in partnership with the City of Ypsilanti and Washtenaw County to increase energy efficiency in the rental housing stock

Community ​Climate Partnership

The Ecology Center, the Huron River Watershed Council, the City of Ann Arbor, along with a growing list of other partners are coordinating a plan to make sure Ann Arbor's Climate Action Plan gets implemented​
