Montgomery County Energy Summit

May 04, 2021 to May 06, 2021


This year's Summit will take place virtually May 4-6. The theme for 2021 is “Resiliency, from Building to Community.” We will explore strategies, technologies, and case studies focused on enhancing the resiliency of the commercial, multifamily, and residential built environment. Not only must we adapt to changing climate hazards in our buildings, but our economy and public health must become more resilient as well. Together, our community can adapt and become more resilient against changes to our regional and global climate, while striving to reach the County’s ambitious goal of zero carbon emissions by 2035.

The Summit will include breakout education sessions, a keynote address, topical networking salons, interactive brown bag lunches. All education sessions will be approved for GBCI and AIA continuing education credits.

Connecting the Corridor: Lessons From a Century of Racism and Resilience along the Purple Line

April 21, 2021 - 6:00 pm to 8:00 pm


Connecting the Corridor will tell the story of how the Purple Line corridor has been shaped by racism and the organizing and resilience communities have shown in response. The event will explore how communities along the corridor have been affected by discrimination and urban renewal, as well as how patterns of residential and economic segregation are perpetuated by contemporary policies. The event will feature presentations from community storytellers from Lakeland, Langley Park, Lyttonsville, and Bethesda, who will describe the personal and enduring consequences of the region’s often inequitable development, with lessons for how our community can make sure that the Purple Line is a force for racial equity and not an instrument of displacement. The event will be facilitated by planner and writer Dan Reed, and the Honorable Parris Glendening, former Governor of Maryland, will deliver remarks.

The event will be held via Zoom from 6:00PM to 8:00PM on Wednesday, April 21. Register here. Formal invite to follow!

The event is presented by Kaiser Permanente, the Coalition for Smarter Growth, and the Purple Line Corridor Coalition.

Prince George's County Growing Green with Pride

May 01, 2021 - 12:00 am to 12:00 am


Prince George’s County will host a Countywide community clean up program entitled "Growing Green With Pride." This event supports our Beautification Initiative to make our community cleaner by conducting individual community litter collection events, which demonstrates our shared commitment to keeping our communities appealing and attractive. Community organizations and groups are encouraged to participate.

Message from the County Executive:

Please join me on Saturday, May 1, 2021 for a countywide effort to safely clean our communities. Due to the COVID-19 pandemic and out of an abundance of caution, we will utilize the Centers for Disease Control and Prevention's (CDC) best practices by implementing a grab-n-go style pickup. However, communities are invited to help us keep Prince George’s County clean and beautiful by placing mulch, picking up roadside litter and removing illegally dumped materials.

In order to keep our communities clean and aesthetically appealing, we must all work together and do our part. If your community or organization would like to join our efforts by participating in the Spring 2021 Growing Green with Pride Day community cleanup event, I encourage you to please complete the registration form. When completing the application, please provide all of the pertinent information requested, including the name and mailing address of your community or organization’s primary contact, the expected number of volunteers, and the area and street name(s) of where your community will be cleaning.

Walk/Bike to School Day

May 05, 2021 to May 06, 2021

Mark your calendar for National Bike to School Day on May 5, 2021, and get ready to bring attention to the value and joy of safe walking and rolling!

The first-ever National Bike to School Day took place on May 9, 2012, in coordination with the League of American Bicyclists’ National Bike Month. Almost 1,000 local events in 49 states and the District of Columbia joined together to encourage children to safely bicycle or walk to school.

The event builds on the popularity of Walk to School Day, which is celebrated across the country – and the world – each October. Many communities and schools have been holding spring walk and bicycle to school events for years. National Bike to School Day provides an opportunity for schools across the country to join together to celebrate and to build off of the energy of National Bike Month.

World Bee Day

May 20, 2021 - 12:00 am to 11:59 pm

Bee engaged!

To raise awareness of the importance of pollinators, the threats they face and their contribution to sustainable development, the UN designated 20 May as World Bee Day.

The goal is to strengthen measures aimed at protecting bees and other pollinators, which would significantly contribute to solving problems related to the global food supply and eliminate hunger in developing countries.

We all depend on pollinators and it is, therefore, crucial to monitor their decline and halt the loss of biodiversity.
