Energy & Climate

Reduce greenhouse gas emissions 80% by 2027 and 100% by 2035.
Achieved carbon neutrality for County government facilities and fleet vehicle operations.

About Energy & Climate

Industrial activities, deforestation, and the burning of fossil fuels release high concentrations of carbon dioxide, methane, and other greenhouse gases (GHG) into the atmosphere. These high concentrations of GHG are leading to rising temperatures, rising sea levels, and more extreme storms across the globe.

Montgomery County has been a national leader in responding to the challenge of climate change. Setting aggressive GHG emissions reduction targets, the County aims to reduce GHG emissions 80% by 2027 and 100% by 2035. To achieve this ambitious goal, the County government must lead by example by:

  • generating solar, CHP, and other low emissions energy on County facilities;
  • reducing fuel consumption through green fleet operations;
  • building high performance green buildings;
  • continually improving energy efficiency of existing buildings; and
  • clean energy purchasing.

Investments in energy-efficiency and renewable energy reduces County operating costs and creates opportunities to grow green businesses. Additionally, electric vehicles charging infrastructure is expanding to support electrification of the County fleet. As of FY2016, Montgomery County achieved carbon neutrality for government buildings and fleet operations as a result of combined energy efficiency, renewable energy investment and energy purchases.


Solar panels

Montgomery County has installed 7.6 megawatts (MW) solar on County facilities and over parking lots. The solar panels generate enough electricity to power more than 800 single family homes reducing greenhouse gas emissions by 7,400 metric tons each year and equivalent to planting 192,000 new trees! The County’s overall goal is to install a total of 11 MW of solar. More...

Green Fleet

Electrical vehicle

Montgomery County is on track to reduce fleet petroleum fuel consumption 20% below 2014 levels by 2020. The County now has 39 electric vehicles and 193 hybrid vehicles in its fleet, installed idle technology on 57 vehicles, converted 28% of Ride On buses to run on compressed natural gas, and uses telematics and driver education to shorten routes and maximize fuel efficiency.

Green Buildings

White Oak Recreation Center

Heating, cooling, lighting, and powering buildings accounts for 40% of greenhouse gas emissions. Montgomery County designs new buildings to achieve a minimum LEED Silver certification, with many achieving LEED Gold. Existing buildings are retrofitted with energy efficiency improvements whenever possible reducing energy use and greenhouse gas emissions. More...

Advanced Energy Projects

Combined heat and power (CHP) saves energy by using waste heat from on-site power generation to heat buildings saving energy and reducing pollution. Microgrids are on-site clean power generation systems that can run independent of utilities using solar panels, CHP systems, batteries, and advanced controllers. The County is installing microgrids at key facilities to allow critical operations to run uninterrupted during prolonged power outages. The County’s first two microgrid projects were completed in 2018 at Public Safety Headquarters and Montgomery County Correctional Facility, incorporating CHP systems. More...

Continuous Energy Improvement

Upgrades to older buildings can result in vast energy savings, also reducing pollution and lowering utility bill costs. Upgrades include:

  • replacing outdated lighting fixtures with energy efficient LED lighting;
  • installing automatic shut off switches for lights;
  • installing low flow fixtures and other water conservation measures;
  • replacing heating and air conditioning systems with more energy efficient models; and
  • improving insulation and ventilation.

The County continuously identifies buildings with high potential for energy savings through data analysis and energy sweeps of the facilities plans cost-effective improvements and builds energy efficiency into building refresh projects. In addition, the County is implementing a six-year plan to invest $120 million in facilities through Energy Savings Performance Contracts (ESPC) companies which recommend upgrades and guarantee energy efficiency.

Clean Energy Purchase

Since FY2016, Montgomery County government has purchased 100% of its annual electricity consumption from clean sources, specifically energy generated by wind turbines. The County also purchases credits to offset greenhouse gas from its facilities. Since 2004, Montgomery County has led a coalition of County agencies and municipalities to purchase electricity supply generated from wind energy. The County led purchase currently ranks fourth among local governments and 31th among all national purchases tracked by the U.S. Environmental Protection Agency’s Green Power Partnership.

Using Data to Manage Building Energy Wisely

More than 80 County buildings have automated building controls that allow technicians to monitor and adjust building temperature, humidity levels, lighting, and more to save energy while keeping staff and building users comfortable and safe. We also closely monitor utility bill data of more than 425 buildings to identify opportunities to improve energy efficiency. Using EnergyCAP software, staff pulls data directly from utilities and investigates and resolves billing issues, along with tracking and analyzing long term trends. More...

Climate and Energy Policy

Montgomery County enhances sustainability by enacting and implementing progressive policies and by advocating for state and federal policies that promote sustainability and resiliency. This includes policy initiatives to secure more reliable, cleaner, and cost-effective energy and programs that reduce energy consumption in public and private buildings. More...

Employee Engagement

Employment engagement

Employee behavior has a significant impact on energy use, water use, and waste reduction. We’re educating employees about how to conserve resources and reduce pollution at work – and at home – through training and events. We’re also encouraging employee participation in pilot telework programs, providing incentives for employees to use public transit, commute by bicycle, or ride share. Check back for more information as we pilot new programs to further engage employees in energy conservation and pollution protection. More...
