Directly involved in every aspect of AllEarth Renewables' day-to-day operations, David brings to the company a lifetime of passion for, and a career’s-worth of experience in, bringing practical, economically sound on-site renewable energy solutions to homeowners and businesses. In 1982 when the wind industry was in its infancy, David founded NRG Systems, his first entrepreneurial venture that grew into an internationally recognized leader in wind measurement technology. Twenty-two years later, David stepped down as CEO of NRG Systems to kick-off his second entrepreneurial venture, AllEarth Renewables, a start-up company dedicated to the development, manufacture and deployment of residential-scale, grid-connected renewable energy systems.

AllEarth Renewables began as Earth Turbines, a small research and development company producing an innovative and durable residential-scale wind turbine currently installed at 20 test sites across Vermont. In 2009, Earth Turbines introduced the AllSun Tracker, a pole-mounted, turn-key solar array that actively follows the sun from dawn to dusk. In 2010, the company reintroduced itself to the industry as AllEarth Renewables to reflect its new emphasis on both wind and sun.

David grew up in Pittsford, Vermont near Grandpa’s Knob, which happens to be the site of the world’s first commercial wind turbine. In high school, he tinkered with paper-cup anemometers and experimented with wind-generated electricity to light his sugarhouse during springtime evening “boils” of maple syrup. His curiosity for renewable energy became a dedication to helping transition the US economy away from its dependence on fossil fuels in 1973 when he got his driver’s license during the Arab Oil Embargo and watched gas prices sky-rocket.

David went on to build a wind turbine as part of his bachelor’s degree in mechanical engineering, which he earned from the University of Vermont in 1981. Still committed to practicing what he preaches, today David's home relies on net metering to produce all of its power. The grid-connected house includes a 6000 watt fixed solar photovoltaic system and solar hot water system on its roof, a wood pellet stove for heating, and a 2500 watt Earth Turbine on a 115 foot tall tower shares the backyard with a 4000 watt AllSun Tracker.

In addition to his duties as CEO, David makes frequent public speaking engagements on our energy future and also maintains several institutional commitments: He is board member and treasurer of the Small Wind Certification Council (SWCC), a non-profit formed to certify small wind turbines. He served as treasurer of the American Wind Energy Association for 16 years, until the spring of 2010, when he became a founding member and treasurer of the Distributed Wind Energy Association (DWEA). He is a board member, founding member and past chair of Renewable Energy Vermont (REV). He serves on the Board of Directors of the Energy Co-op of Vermont, Vermont Businesses for Social Responsibility (VBSR), and the Association for the Study of Peak Oil and Gas (ASPO-USA). David is also a member of the Board of Advisors for the Union of Concerned Scientists, the University of Vermont's Rubenstein School of Environment and Natural Resources, the SUNY-Canton Engineering School, and the Vermont Manufacturing Extension Center (VMEC).

David has two grown children, Alyssa and Evan. In his spare time, David enjoys “wind power” recreationally, in the form of hang gliding and sailing.
