Adapt

Advancing DC-ready appliances & technology




Direct current (DC) is the power of our sustainable energy future – produced by solar panels, stored in batteries, and consumed by the lights and appliances we have in our homes and offices already.

Adapt supports and coordinates the growing market for DC-ready appliances and lighting products. We envision a future where AC and DC power generation, distribution, and use coexist within our homes and buildings.

Adapting to DC

Designed a century ago, our alternating current (AC) power distribution system is showing its age. Inefficient, inflexible, and increasingly fragile, it was created at a time when today’s diverse energy demands could not have been imagined.

Today, however, an alternative method of generating and delivering electricity within homes and buildings is emerging – direct current or DC power. More than five thousand solar energy systems, which generate DC power, are installed on US rooftops every week, challenging traditional electric utility service models. Soon many buildings will be outfitted with batteries for on-site, DC energy storage. Our electronics, modern LED and fluorescent lighting, and many of today’s appliances require DC to function, but first convert AC to DC through adapters or ‘wall warts.’ Together, these native DC loads – loads that must run on DC – account for about 32% of US residential electricity use, while resistive loads that can run on either AC or DC comprise 37%. The prevalence of DC power in the home will only increase with the proliferation of efficient lights, consumer electronics, advanced motor-driven appliances, and eventually electric vehicles.

We envision a future where AC and DC power generation, distribution, and use coexist within our homes and buildings. In this scenario, DC power is put to use where it is produced and stored, rather than converted, exported to the grid, and converted again. With DC power, we can unlock remarkable benefits for consumers, product manufacturers, and the environment, including:

  • Major market opportunities for appliance manufacturers and solar and energy storage companies
  • Lower energy bills for consumers
  • More efficient, reliable, and higher-performing appliances with reduced materials and shipping costs
  • Improved resiliency, lower electricity demand, and reduced carbon emissions. 

There are three parts to the DC equation: supply (generation); distribution; and demand (consumption). The first two are progressing already. On the DC generation side, renewable energy companies and battery storage and electric vehicle manufacturers continue to grow their markets and increase the presence of DC power in homes. In terms of DC distribution, coalitions of businesses, non-profits, and government organizations are busy developing standards and components necessary for reliable DC power distribution in buildings. However, there has not been a coordinated effort to promote the demand for DC through the manufacture of DC-ready lighting and appliances. Appliances and lighting are the most important interface between people and energy in the home.

Adapt supports and coordinates the growing market for DC-ready appliances and lighting products. Additionally, and with the rapid proliferation of distributed renewable energy technologies in the developing world, highly efficient DC products present a significant sustainable development and business opportunity. Adapt seeks to align these commercial forces and markets to benefit rapid adoption of efficient DC appliances and technologies worldwide.

Within the next three years, we will set a clear path to market for DC-ready appliances, fostering competitive commercial markets for high-quality, high-efficiency, and appropriately designed DC-ready appliances, and amplifying opportunities for manufacturers and others.

We have set the following goals:


Achieving this vision will require cooperation, open dialogue, and a shared commitment among those who have a stake in generating, storing, distributing, and consuming DC power.
