Explore Active Efficiency
Active Efficiency brings together a variety of technologies and practices to achieve a greater optimization of energy.
Click the categories in the web to explore the Active Efficiency universe, including the overarching objectives that shape its design, the technological tools and resources that can be combined into implementation strategies, and the results.
Reduced Climate Emissions
Decarbonization is a key policy strategy to reduce climate emissions. Active Efficiency offers a framework for harnessing the potential of digital technologies and renewable energy resources to optimize energy use and achieve this policy goal.
Equity & Social Justice
When implemented with a proactive strategy to ensure equitable outcomes, Active Efficiency can provide tools to improve affordable access and quality of service for all consumers, including frontline/underserved customers.
Active Efficiency presents many opportunities for economic growth, including net bill savings for consumers, creation of new value streams in energy and capacity markets, better optimization of the grid, and job creation in numerous sectors.
Reliability, Resilience, & Adaptation
Active Efficiency strategies can improve the grid’s reliability and resilience by minimizing energy waste and deploying technologies and practices to enhance demand flexibility, resulting in a more responsive relationship between supply and demand.
Internet of Things (IoT)
This network of physical objects, embedded with sensors and software to connect and exchange data over the internet, can be coordinated to enable insights on usage patterns, ensure the more efficient use of energy, and support demand flexibility.
Advanced Analytics, Cloud-based Platforms, Edge Computing, Big Data
IT advances in advanced analytics and computing are accelerating, reinforcing innovations that produce a myriad of opportunities for Active Efficiency, ranging from distributed energy resource (DER) aggregation to digital twinning.
Predictive & Automated Controls
As digital energy management tools and strategies become more complex, controls that have the ability to predict and automate energy use are critical for optimizing energy and providing a more streamlined customer experience.
Advanced Metering & Controls
An integrated system of smart meters, communications networks, and data management systems that enables two-way communication between utilities and customers. Such infrastructure is a critical foundation for Active Efficiency.
The consistent deployment of high-speed data transmission that provides constant, reliable internet connection is necessary to ensure all customers are able to benefit from digitalized Active Efficiency opportunities.
Distributed Energy Resources (DERs)
Resources sited close to customers that can provide electric and power needs. Deployment and coordination of DERs with Active Efficiency can reduce peak period demand and provide supply to satisfy energy, capacity, or ancillary service needs.
Traditional Energy Efficiency
The reduction in energy demand gained through strategies that are typically static and not digitalized, such as vehicle, equipment, and appliance replacement; weatherization; and behavioral change.
The voluntary reduction or shifting of customer electricity usage, often in response to financial incentives, to improve grid conditions during peak periods and/or optimize the dispatch of variable energy resources.
The transition from fossil fuel end-uses to electricity in circumstances where specific benefits are achieved. When combined with demand flexibility, it serves as an opportunity for wider energy optimization, and a clear example of Active Efficiency.
Efficiency Maine Trust
Systems that allow energy to be stored when plentiful, used onsite when needed, or returned to the grid during periods of low production or high demand. By reducing the need for backup generation, storage increases grid efficiency and reliability.
A localized energy system that can disconnect from the grid and operate autonomously in case of energy disruptions. By implementing Active Efficiency strategies, microgrids can leverage DERs to enhance grid efficiency, flexibility, and reliability.

Deep Energy Efficiency Retrofit
An upgrade that uses a whole-building evaluation of energy performance to optimize multiple systems and achieve significantly larger energy savings than retrofits focused on upgrading isolated systems.
The ability to shift electricity demand to times of day when power is abundant and low-cost, which reduces costly peak loads and makes energy more reliable and affordable. A fundamental tool of energy optimization and Active Efficiency.
Grid-interactive Efficient Building (GEB)
An energy-efficient building with smart technologies characterized by the active use of DERs. GEBs enable demand flexibility and help optimize energy use for grid services, occupant benefits, and cost reductions.
V2G technology allows bi-directional charging between electric vehicles and the grid. Electric vehicles can serve as distributed energy resources for the grid, particularly during times of peak electricity demand or power disruptions.
Performance-based Utility Program
A program that delivers energy savings and demand flexibility by incentivizing energy/demand reductions over a specified time period. Well-designed programs can ensure all consumers reap the multiple benefits of GEBs and other Active Efficiency approaches.
Dynamic & Customized Solutions
Smart and connected devices and systems enable consumers to take an Active Efficiency approach to energy use – customizing how they track energy performance, how much energy they use, and when they use energy.
Building automation systems – sensors and controls that are programmed to monitor and regulate building equipment and system operation – are a key technology for optimizing building performance and energy use through Active Efficiency approaches.
Evaluation, Measurement, and Verification (EM&V)
A set of processes to determine energy savings impacts of projects or programs. Advanced metering and other technologies improve EM&V’s accuracy at a lower cost. In turn, improved EM&V validates the efficacy of Active Efficiency approaches.
Seattle City Light’s MEETS program
Other Programs & Policies
Programs & policies that support Active Efficiency approaches include incentives for smart devices, performance-based energy savings metrics, real-time energy pricing, and developing valuation methods for co-benefits of improved energy performance.
The coordination within and between energy systems across multiple pathways and scales (e.g., buildings, campuses, cities, whole regions) to optimize energy in real-time, achieving greater energy savings than component-focused efforts.
Real-Time Energy Management
Real-Time Energy Management is the modulation of energy use according to real-time conditions on the grid, allowing for a more meaningful optimization of supply and demand, and creating benefits such as cost savings and emissions reductions.
Integration/Optimization Across the Meter
Active Efficiency tools and strategies can modulate both energy demand (i.e., “behind the meter”) and supply, leading to a more comprehensive energy optimization.
Shaving Peaks & Energy Costs
The prioritization of consumer needs – such as affordability, convenience, and a seamless user experience – in an efficiency program, project, product, or recommended practice.
Steep Emissions Reductions
If optimally deployed, the full suite of measures in the Active Efficiency toolbox will contribute to the steep greenhouse gas emissions reductions required before mid-century to avoid the worst effects of climate change.
Equitable, Accessible Energy Costs
Nearly one-third of U.S. households struggle to meet energy needs. Well-designed Active Efficiency strategies can support equitable and affordable energy systems that are critical for low-income, minority, and other underserved communities to thrive.
Better Quality of Life and Service
Integrating Active Efficiency strategies in energy management can deliver enhanced health, comfort, and other benefits to occupants as a result of improved indoor air quality, temperature regulation, and noise levels in the built environment.
Active Efficiency in Action
The best way to understand the value of Active Efficiency is to see it in action. There are many examples that demonstrate the potential of Active Efficiency. Between the economic, social, and environmental benefits, the hard work that goes into making these examples successful is something to be celebrated.
