Top Ten U.S. Cities Ranked For Climate & Renewable Energy Policies

Sustainable Business & Enterprise Roundtable (SBER) Member-clients are formulating and pursuing aggressive renewable energy goals and almost all have substantial presence in multiple large U.S. cities. Consequently, Member-clients have requested a quick survey of what the most advanced large U.S. cities are doing to meet their climate change goals, especially as they consider potential partnerships with the cities they operate in to advance a shared commitment to accelerating the necessary move to a low carbon economy.

Since this concerns public information, Sustainability Roundtable Inc. wanted to share this ranking of large U.S. cities leading on the low carbon economy on our blog.  This post, therefore, explores ten large U.S. cities leading through their relatively bold commitments to reduce their greenhouse gas (GHG) emissions and advance renewable energy. This movement is, of course, much broader than the listed cities.

For example, twenty-nine U.S. cities and counting have committed to transition their power source to 100% renewable energy. An interactive map created by the Sierra Club reveals that seven of those cities have already hit their renewable energy targets– Aspen, CO, Burlington, VT, Columbia, MD, Greensburg, KS, Kodiak Island, AK, Rockport, MO and Santa Monica, CA. The map also features 22 other cities committed to 100% renewables, including San Diego and San Francisco, CA, along with 39 cities currently working towards 100% renewables, including Chicago, IL, Denver, CO, Oakland, CA, and Philadelphia, PA.

For the convenience of Member-clients and others, we provide the following informal ranking of cities’ efforts in specifically pursuing renewable energy to reduce their GHG emissions, highlighting selected progress.  Five of those listed are part of the Carbon Neutral Cities Alliance (Boston, DC, New York City, Portland and San Francisco).

#10. Philadelphia, PA: Financing solar in Philadelphia has been challenging over the years, but the City has made significant strides in making it easier, faster and cheaper to install – and has been recognized as a SolSmart Gold designee – which helps the city reach its 80% GHG reduction goal by 2050.

Philadelphia’s Office of Sustainability is responsible for driving Greenworks Philadelphia, the City’s comprehensive sustainability plan which was first launched in 2009. Philadelphia’s 2016 Greenworks Plan outlines a goal to reduce GHG emissions 80% by 2050, below a 2006 baseline and the City is currently establishing new local government energy and climate targets. As part of the eight visions of Greenworks, the third vision focuses on clean energy that all Philadelphians can afford.

  • 2016 Population: 1,526,006.
  • Philadelphia had 10 MW of solar PV installed by the end of 2016.
  • The City’s solar and wind installation at Lincoln Financial Field generates three megawatts of energy responsible for 1/3 of the City’s solar capacity.
  • As a SolSmart Gold designee, Philadelphia is receiving national recognition for its work to reduce solar permitting costs, create a Solar Guidebook, and update their expedited permitting process.

Beginning in 2009, the City of Philadelphia purchased 20% of its total annual energy through national wind RECs. In 2014 the City shifted its purchasing strategy from national to state RECs, focusing City dollars on supporting local projects. While local RECs are more expensive, the Energy Office is committed to using Philadelphia’s buying power on the REC market to spur the growth of renewable energy close to home. The increase in renewable generation in Philadelphia has come not through solar alone, but also through projects like the PWD’s biogas cogeneration plant at its Northeast Water Pollution Control Plant.

p5According to Greenworks Philadelphia, the state’s alternative energy portfolio standard and initial investment in solar through the PA Sunshine Program helped create a market for solar renewable energy credits (SRECs). The end of the Sunshine Program and the lack of sufficient expansion of the portfolio standard (and the ability of utilities to meet requirements by purchasing solar energy outside of Pennsylvania) have made financing solar projects in Philadelphia challenging in the past years.

 

#9. Chicago, IL: The City of Chicago has the same GHG reduction goal as Philadelphia but recently announced to power municipal operations with 100% renewable energy by 2025 which is currently being met through a combination of Renewable Energy Credits (RECs), utility-supplied renewable energy, and on-site generation.

The City launched the Chicago Climate Action Plan (CCAP) in 2008 to create a roadmap of five strategies – including clean and renewable energy sources as number two– to reduce GHG emissions and adapt to climate change. The Plan outlines how Chicago will achieve its mid-term goal of 25% reduction by 2020 and its ultimate goal of 80% reduction below 1990 GHG levels by the year 2050. Chicago also has goals to improve citywide energy efficiency by 5%; improve overall energy efficiency in municipal buildings by 10%; and create an additional 20 MW of renewable energy consistent with the Illinois Renewable Portfolio Standard, including installing 10 MW of renewable energy on City properties.

  • 2016 Population: 2,695,598.
  • Chicago had 13 MW of solar PV installed by the end of 2016.
  • The City provides annual reports on progress towards its goals in the Sustainable Chicago Action Agenda.
  • Chicago has reduced its carbon emissions by 7% from 2010 to 2015.
  • In 2010, a solar field consisting of 5,000 solar panels, covering over 2.3 acres, was completed on top of a 30-million-gallon underground reservoir. This roof generates over 1 MW of electricity annually.
  • Mayor Rahm Emanuel and City leadership announced on April 9, 2017, more than 900 city-owned buildings will shift to 100% renewable energy by 2025.
    • City Buildings, Chicago Public Schools, Chicago Housing Authority, Chicago Park District, and City Colleges of Chicago use almost 1.8 billion kWh of energy (8% of the city’s total use).
    • With initial purchases to begin in 2018 and 2019, the commitment will be met through a combination of acquiring RECS, utility-supplied renewable energy via Illinois’ Renewable Portfolio Standard, and on-site generation.
  • Chicago Solar Express makes installing solar easier by cutting fees and streamlining and standardizing permitting and zoning processes
  • A list of renewable energy consultants and working groups that the city has worked with can be found here.

#8. Boston, MA: Pulling ahead of Chicago, the City of Boston exceeded its 25% GHG emissions reduction goal by 2020 seven years early, achieving it through renewable energy programs and installations, paired with energy building ordinances which helped the City achieve a #1 ranking in energy efficiency.

Boston’s initial climate goals were formally adopted in 2007 with Executive Order 3-3890. In 2014, Mayor Walsh released the Greenovate Boston Climate Action Plan Update to reveal the City’s progress towards GHG emissions reduction and outline its strategies. The City announced it had reduced municipal GHG emissions by approximately 27%, meeting its 2020 goal of 25% reduction seven years early and on track to meet its long-term goal of 50% reduction by 2050. The Climate Action Plan outlines 2020 targets that include 15% energy use from co-generation and 10 MW of additional commercial solar. Boston plans to expand on-site renewable energy, district energy, and combined heat and power, along with promoting renewable energy purchasing, including buildings that have linked off-site renewable projects.

  • 2016 Population: 667,294.
  • The City of Boston had 20 MW of total solar PV installed by the end of 2016.
  • The report, Shining Cities: How Smart Local Policies Are Expanding Solar Power in America released April 4, 2017, ranks Boston 21st among major U.S. cities for solar, ahead of Philadelphia, Seattle and Miami for the total amount of installed solar, but behind Newark, NJ, Portland, OR, and DC.
  • According to the third edition of the City Energy Efficiency Scorecard, recently delivered by the American Council for an Energy-Efficient Economy (ACEEE), Boston remains the number one U.S. city for energy efficiency. Boston’s solar programs and building energy reporting ordinances have helped the City achieve this national recognition.
  • Since Boston is one of the windiest cities in the nation, the Boston Redevelopment Authority created new zoning laws for wind turbines.
    • The installation of a 1.5 MW turbine in Charlestown and two 600 KW turbines on Deer Island, generate more than 5 million kWh, saving roughly $600,000 each year.
    • In 2008, the Massachusetts Port Authority installed 20, 12-foot tall wind turbines on the roof of Logan Airport’s offices which utilize stable winds along the waterfront.
  • Boston’s Municipal Greenhouse Gas Inventory Summary reveals the City started buying RECs primarily from Midwestern wind farms in 2005.
  • Solar is also a critical source to meet Boston’s climate action goals. Boston has created many programs to expand solar energy, such as the Renew Boston solar program which helps Boston residents, businesses and institutions save money and energy.
  • The City’s interactive BERDO Mapping Tool calculates metrics for renewable energy for all buildings.

#7. Oakland, CA: Oakland may be the “other” city in the Bay Area but it is a national and global leader in greater sustainability.  Oakland is on track to reduce GHG emissions 36% by 2020 through residential and government solar programs including community choice aggregation as the City plans to add 62 million kWh of new renewable energy used to meet local needs, annually.

The Sustainable Oakland program is an evolution of the Sustainable Community Development Initiative, established by Oakland’s City Council in 1997, and supports Oakland’s progress in becoming a more sustainable city. The Oakland Energy and Climate Action Plan (ECAP) was adopted by the City Council on December 4, 2012 and outlines a ten-year plan including more than 150 actions that will enable Oakland to achieve a 36% reduction in GHG emissions by 2020 and 83% by 2050, below 2005 levels. The plan consists of a 32% decrease in electricity consumption through renewable generation, conservation and energy efficiency. It also includes a goal to add an annual 62 million kWh of new renewable energy used to meet local needs. Specifically, Action BE‐45 outlined in Oakland’s ECAP states: explore opportunities to install alternative energy technologies (e.g. via solar power purchase agreements) or purchase grid-based renewable energy for City facilities.

  • 2016 population: 390,724.
  • Sustainable Oakland’s website reveals that throughout the city, there were a total of 1,819 residential and non-residential solar systems at the end of 2013, with a total generation capacity of 15 MW.
  • The City installed a 372 kW system atop the Oakland Ice Center. The system generates 31% of the electricity used at the facility.
  • Additionally, a 760 kW system on the Municipal Service Center in the Coliseum Business Park generates 82% of the four buildings’ energy load, covering 85,000 square feet.
  • The City has also installed solar thermal systems on Fire Station 18 and the East Oakland Sports Center.
  • Oakland is a member of the Local Government Sustainable Energy Coalition’s Energy Policy Committee which focuses on energy efficiency, clean energy and community choice aggregation (CCA).
  • Sustainable Oakland’s 15/16 Progress Report presents findings from its 2016 emissions inventory and discovered Oaklanders reduced their GHG emissions 14% since 2005 from all sectors of the community – residential, commercial, and local government.

#6. District of Columbia (DC): DC has been reducing its emissions through one of the largest 20-year off-site wind PPAs of its kind ever entered into by an American city which serves 35% of the government’s total electricity needs.

The District’s first Climate Action Plan, Climate of Opportunity, provides an outline for District agencies to cut emissions. DC is committed to reducing GHG emissions 50% below 2006 levels by 2032 and 80% by 2050. The Department of Energy & Environment (DOEE) has been working on updating the Climate Action Plan to align it with the goals and initiatives of Sustainable DC, moveDC and Clean Energy DC. Sustainable DC’s 2032 targets include reducing energy use by 50% relative to 2012 and increasing renewable energy to represent 50% of all energy used in the District.

  • 2016 Population: 561,702.
  • DC had a total of 25 MW of solar PV installed by the end of 2016.
  • The Sustainable DC 2017 Year Progress Report highlights key projects and initiatives, and summarizes basic progress on the Plan.
  • In December, 2015 Mayor Muriel Bowser entered into one of the largest municipal on-site solar projects in the U.S. to boost the city’s total solar generation capacity by roughly 70% through the deployment of 11.4 MW of solar PV systems on the roofs and parking lots of 34 District-owned facilities. This was through the DC Department of General Services’ (DGS) Power Purchase Agreement (PPA) with DC-based, Nextility Inc.
  • DGS expects additional peak-season cost savings for electricity purchases from off-site energy sources in the summer months, when both demand and solar output is often greatest.
  • On top of the immense solar generation, DGS signed the largest 20-year off-site wind PPA (in PA) of its kind ever entered into by an American city in July 2015, which serves 35% of the government’s total electricity needs from a wind farm.
  • The District’s commitments to sustainable energy were recognized by the U.S. Environmental Protection Agency (EPA) with a Green Power Leadership Award in 2015.

DC6DC extended its Renewable Portfolio Standard (RPS) target from 20% by 2020 to 50% by 2032 which includes a separate solar-specific target of 5% by 2032. In 2015, electricity sales in the District totaled 11.3 billion kWh with an RPS requirement of 12%. Since DC has limited renewable capacity, almost all of the RPS compliance targets were met by generation outside of the District through the purchase of RECs.

DC719 states outside of DC have approved capacity that can count toward DC’s RPS, as they are all part of or adjacent to the PJM region. Because some of these states may have their own renewable portfolio standards, the eligible generating capacity may not necessarily be fully available to meet the District’s RPS requirement. About half of the approved capacity is in Illinois, Indiana, and Pennsylvania. The 22 MW of solar capacity in DC represented only 0.3% of total eligible capacity as of July 2016.

#5. Denver, CO: Currently exploring pathways to get to 100% renewable energy, Denver had 45 MW of solar installed by 2016 and has outlined strategies to double renewable energy produced in government operations by 2020 while partnering with Xcel Energy on solar and wind projects.

Denver’s long-term climate reduction goal highlighted in the City’s 2015 Climate Action Plan is to reduce GHG emissions 80% by 2050 from a 2005 baseline. Denver’s Office of Sustainability has formally adopted separate community-wide goals and government operations goals as part of Denver’s 2020 Sustainability Goals. Community-wide goals include reducing Denver’s CO2 emissions to below 1990 levels and holding total energy usage below 2012 levels while cutting fossil fuels by 50% by 2020. Denver’s government operations goals include reducing city GHG emissions to <345,000 mtCO2e and a 20% energy consumption reduction as city operations double renewable energy produced by 2020. Denver is currently exploring pathways to get to 100% renewable energy.

  • 2016 Population: 682,545.
  • Denver had 45 MW of installed solar by the end of 2016.
  • Denver International Airport has four solar arrays installed generating 10 MW of solar developed by Denver-based Oak Lead Energy Partners under a 20-year PPA.
  • Oak Leaf Energy has completed 68 additional solar projects, including the projects for the Denver Housing Authority and the Denver Public School System.
  • The Denver Housing Authority also agreed to a PPA with Enfinity America Corporation enabling the installation of 2.5 MW of solar on more than 350 Authority affordable housing properties.
  • A strategy in place to meet Denver’s GHG goals is to Partner with Xcel Energy to rapidly attain a lower emissions factor for electricity through system efficiencies, additional renewable energy projects and no-carbon sources.
  • Denver has many programs in place to help its residents and businesses become more efficient in lighting upgrades and solar, such as the Denver Energy Challenge.
  • The Office of Sustainability last updated their government operations progress report in February 2017. The report reveals government operations decreased GHG emissions year-over-year. To meet their 2020 GHG goal, Denver will require significant momentum and implementation of major strategies.

#4. Portland, OR: Portland ranks fourth on our list since the city achieved its goal of purchasing or generating 100% renewable energy for City operations in 2016, which was successfully met through solar, micro-hydro turbines, a cogeneration system and RECs.

Portland was the first city in the U.S. to create a local action plan for cutting carbon in 1993. Portland’s 2015 Climate Change Action Plan concludes the City and County established a goal of reducing local carbon emissions 80% from 1990 levels by 2050, with an interim goal of 40% by 2030. In 2015, Portland City Council adopted the Sustainable City Government 2030 Environmental Performance Objectives, directing City operations to purchase or generate clean power for 100% of electricity needs which was achieved a year later.

  • 2015 population: 632,309.
  • Portland had 27 MW of solar PV installed by the end of 2016.
  • The 2015 Climate Action Plan calls for supplying 50% of all energy used in buildings from renewable resources, with 10% produced within Multnomah County from on-site renewable energy sources or district renewable energy sources such as solar, biogas, in-pipe microhydro and biomass.
  • According to Portland’s 2017 Climate Action Progress Report, the City completed renewable energy purchases to meet its FY15/16 electricity demand with 100% renewable energy. The City generated 7% of its electricity from on-site renewable energy systems including solar, micro-hydro turbines and a co-generation system; local electric utilities provided 15% of their supply from renewable resources; and RECs were purchased to offset the remaining electric utility supply.
  • The City was awarded a competitive grant from Pacific Power’s Blue Sky renewable energy program for the design and installation of a solar array at the North Police Precinct (scheduled to be completed in 2017).
  • Portland has one of the highest participation rates in voluntary green power purchase programs in the country, with participants accounting for more than 7% of all electricity sales.
  • The City and County have participated in several relevant PUC dockets and legislative proceedings related to renewable energy policy. This includes PUC proceedings on community solar, solar incentive program design, voluntary renewable energy tariffs, resource value of solar and renewable portfolio standard (RPS) legislation (Clean Electricity and Coal Transition Act of 2016).
  • The 2017 Progress Report indicates that compared to 1990 levels, total carbon emissions from commercial buildings and the industrial sector have declined 15% and 37%.

#3. San Francisco, CA: San Francisco set an ambitious goal to meet 100% of its electricity demand with renewable power community-wide by 2030 and is on track to achieve that goal through its first-in-the-nation mandate of solar and living roofs on residential and commercial buildings.

The San Francisco Department of Environment released the 2013 San Francisco Climate Action Strategy Update, under Mayor Edwin Lee. San Francisco’s GHG emissions reduction goals are to reduce emissions by 25% below 1990 levels by 2017; 40% by 2025; and 80% by 2050.  The 2017 target came two years ahead of schedule, set in 2008, and puts the city on track toward its ultimate goal of an 80% reduction by 2050. San Francisco is committed to meeting 100% of its electricity demand with renewable power community-wide by 2030.

#2. New York, NY: By far the largest city on our list, New York City, installed 74 MW of solar in 2016 and has created strong partnerships citywide to implement the City’s comprehensive plans for large-scale solar integration, grid independence and battery storage.

In 2015, Mayor Bill de Blasio announced a Request for Information (RFI) to identify new renewable energy generation capacity, with a goal of powering 100% of City government operations from renewable sources. Under One New York: The Plan for a Strong and Just City (OneNYC) and One City: Built to Last, Mayor de Blasio has committed to a 10-year roadmap of policies regarding dramatic reductions in GHG emissions, from City government operations and citywide. The City has pledged to reduce overall GHG emissions 80% by 2050 and emissions from City government operations 35% by 2025.

  • 2016 Population: 8,537,673.
  • Private and public solar installations in the City totaled almost 74 MW in 2016. Public solar capacity has increased to nearly 9 MW and private solar capacity has nearly tripled from 24 MW at the beginning of 2014 to nearly 65 MW, which helped to drop GHG emissions by 19% from 2005 levels.
  • Mayor de Blasio pledged to install 100 MW of new solar on public buildings and 250 MW of new solar on private buildings by 2025 through One City: Built to Last. Concurrently, the plan provided funding for the NYC Solar Partnership to continue to reduce market barriers for solar; attract more solar energy companies to the city and create more jobs; and increase the city’s installed solar capacity.
  • Partners helping to advance the Mayor’s goal of increasing solar are the NYC Solar Partnership which is led by Sustainable CUNY of the City University of New York, the New York City Mayor’s Office of Sustainability, and the New York City Economic Development Corporation.
