As an approved subscription manager in the Oregon Community Solar Program, we operate within the state-regulated framework to make the benefits of going solar accessible to customers of PGE and Pacific Power. For too long, most people have been sidelined from accessing the benefits of clean solar energy due to factors like renting, cost, or roof limitations. Community solar provides a simple and equitable alternative, allowing anyone with an eligible utility account to choose clean energy with no upfront cost and no sign up fees.

Check out Lake Oswego’s newest sustainable school

A Sustainability Tour of the New Lake Oswego Middle School

Photo of the Lake Oswego Middle School cafeteria

Members of the Lake Oswego Sustainability Network Schools Action Team recently toured the newly constructed Lake Oswego Middle School and learned how sustainability has been thoughtfully integrated throughout the campus.

The school’s design was shaped by extensive research into the material, cultural and ecological histories of the site and surrounding community. From colors, patterns and textures to native plants and natural materials, the building reflects and celebrates the unique character of our region.

Building on Lake Oswego School District’s longstanding commitment to sustainability, the school incorporates a high-performance building envelope, passive cooling, rooftop solar panels, smart stormwater management and biophilic design elements that connect students with nature. Sustainable transportation is supported through ample bicycle, skateboard and EV-ready parking.

Photo of the Lake Oswego Middle School grounds and basedball field

Inside, student well-being and energy efficiency go hand in hand. Spaces are designed to support their intended use, with calming blue tones in music rooms and other thoughtful design elements throughout the building. Smart window indicators and a highly efficient wind-turbine ventilation system help maintain a comfortable, healthy indoor environment. Classrooms feature hearing-assistance technology, collaborative learning spaces and accessibility-focused amenities, including a life skills classroom and a dedicated Zen room.

Photo of the Lake Oswego Middle School greenhouse and garden

The campus itself serves as a living example of environmental stewardship. Rain gardens collect and filter runoff before it infiltrates into underground vaults beneath the parking lot, while native meadows, gardens and a greenhouse provide hands-on opportunities for environmental learning.

Solar panels cover much of the roof and are designed to generate enough electricity to power the entire building, further reducing the school’s environmental footprint and supporting district sustainability goals.

The new Lake Oswego Middle School demonstrates how sustainability, student wellness, accessibility and community identity can be seamlessly integrated into a modern learning environment—one that not only educates students but also models a more sustainable future.

Announcing the 2026 Mary Ratcliff Sustainability Awardees

This year marks the third year that LOSN has bestowed the Mary Ratcliff Sustainability Award of $1,000 to a graduating senior at each of our two high schools. We are pleased to recognize Julianna Cahill from Lakeridge High School and Auveen Shafaei from Lake Oswego High School as our 2026 recipients. Congratulations!!

LOSN established the Mary Ratcliff Sustainability Award in 2024 in memory of Mary Ratcliff and as a way to recognize high school graduates who have already contributed to sustainability and have a vision of how they would like to do so in the future.

Lake Oswego School District Adopts New Strategic Plan

On June 8, the Lake Oswego School Board adopted a new strategic plan that will provide the district’s direction for the next five years.  Lake Oswego Sustainability Network’s School Action Team was active in the process and providing recommendations. We are pleased to say that sustainability has remained an important part of the plan. It is one of the four identified conditions of success along with Belonging and Inclusivity; Health and Resiliency; and Innovation and Technology.

At a high level, LOSD has committed to decisions being guided by an equity lens and a sustainability lens. The Sustainability lens was developed by the Board-appointed Sustainability Advisory Committee several years ago.

The plan also includes:

Improvement commitments:

  • Integrate sustainability into operations and resource use
  • Integrate environmental learning into existing instruction and student experiences
  • Promote responsible stewardship of resources

 Indicators:

  • Operational Data: Sustainability practices in facilities, transportation and resource use
  • Student Participation: Participation in sustainability-related learning and       activities
  • Implementation Data: Integration of sustainability practices across schools and programs

Initiatives the district has identified for the first year with respect to sustainability:

  • Launch a climate-focused professional learning program and support participating teachers in implementing sustainability-connected lessons
  • Implement volunteer-supported lunch composting programs in all elementary schools
  • Establish baseline measures and public reporting on energy use, waste reduction and participation in sustainability initiatives

LOSN is excited to continue to work with the school district to support sustainability in its education and practices.

Help Support LOSD Sustainability Professional Development

The Lake Oswego School District (LOSD) wants to train all of their teachers in sustainability education. The online training, Subject to Climate, equips teachers to implement sustainability concepts into subject areas that they already teach.

In order to start this project, two teachers from each school will train, create lessons that integrate with their current units of study, meet, and create a hub of lessons for the rest of the teachers to use.

There is no budget for this professional development, but there is a lot of enthusiasm among teachers. The training costs $250 per teacher. The Lake Oswego Schools Foundation is managing the funds. We invite you to donate any amount to help get this project off the ground.

Lake Forest Home Uses EV During Power Outages

This property in Lake Oswego is equipped with state-of-the-art Vehicle-to-Home (V2H) technology, providing the capacity to run essential household appliances for up to three days using only the energy stored in the electric vehicle’s battery. During prolonged grid outages, residents can maintain indefinite power by “topping off” the vehicle battery at local fast-charge stations before returning to reconnect the vehicle to the home system.  As a bonus, the homeowner estimates that he saves $100 per month by using less expensive stored energy from his vehicle battery during peak times.
