On Samsø Island in Denmark, Søren Hermansen led a community of 3,724 to achieve their zero-carbon goals in ten years. Today, every person on the island has a negative carbon footprint. What can cities in Vermont learn from Danish methodologies of stakeholder engagement so they can reach their carbon reduction goals?
Renewable energy resources – including solar, wind, geothermal, hydroelectric, biomass (any organic non-fossil material of biological origin), ocean thermal, wave action, and tidal action – are becoming a larger part of the American energy portfolio.
The origin stories for heat pump technology are economic. Applying Lord Kelvin’s theory that disputed the concept that heat could only flow ‘downhill’, Peter von Rittinger turned an expensive wood-based salt processing enterprise into a money maker by using heat pumps to desiccate salt brine. In the 1970s during the oil embargo, modern heat pump sales increased by 500% as heating and cooling costs squeezed homeowners. The innovation of ductless heat pumps in Asia created an alternative to costly kerosene space heaters and PTAC units. The energy efficiency of heat pumps directly translates into financial savings; why does the U.S. market still pale in comparison to the rest of the globe (Figure 1)?
