East Hampton’s 100% renewable energy goals go beyond the electricity sector (getting 100% of annual community-wide electricity consumption from renewable sources is anticipated for 2022). The adopted goals include that the equivalent[1] of annual community energy consumption in two additional sectors  – transportation and heating – be achieved with renewable energy sources by the year 2030.

Renewable heat is an application of renewable energy and refers to the renewable generation of heat, rather than electrical power (e.g. replacing a fossil fuel boiler using concentrating solar thermal to feed radiators). Renewable heat technologies include renewable biofuels, solar heating, geothermal heating, heat pumps and heat exchangers to recover lost heat. Significant attention is also applied to insulation.

In New York State, conventional heating and cooling systems are responsible for 37 percent of energy consumption and 32 percent of greenhouse gas emissions. Clean heating and cooling technologies, such as heat pumps, are making it possible for homes to stay comfortable year round, save energy, and reduce their carbon footprints.

Heat pumps are two to four times as efficient as conventional oil, propane, or electric resistance heating, and ground source heat pumps provide cooling much more efficiently than other cooling systems. They are also a safer and healthier choice for homes, with no combustion of fossil fuels, fuel storage, or carbon monoxide emissions.

Mini-split ASHP
Air source heat pumps, like this mini-split (aka ductless) system extract heat from the air outside and distribute it inside your home or business. During warmer months, the process is reversed to provide cooling by pulling heat out of your interior space.

There are two primary types of heat pumps sold today—air source and ground source heat pumps. When buying or replacing your heat pump, always look for ENERGY STAR® certified heat pumps, which are more energy efficient than other options. In addition, the Coefficient of Performance (COP), Seasonal Energy Efficiency Ratio (SEER), and Heating Seasonal Performance Factor (HSPF) can help determine which option or model will be the most energy efficient. The higher the rating, the more efficient the heat pump will be.

GSHP
Ground source heat pumps (aka geothermal heat pumps) extract heat from the ground during cold weather via an underground pipe system, which is then distributed throughout your home or business. During warmer months, the process is reversed to provide cooling.

If purchasing a heat pump, you may also be eligible to receive a tax credit and/or a financial incentive. Visit NYSERDA’s Air Source Heat Pump and Ground Source Heat Pump program pages to learn more. Your utility may also offer additional incentives and reduced electric rates.

Performance and life expectancy of these systems are dependent upon installation, location, fuel, maintenance, and occupant behavior. (Source)

Comfort at the community level

The Clean Heating and Cooling Communities program is getting groups of homes and businesses in New York State to install clean heating and cooling (CH&C) technologies. These technologies can help lower energy bills and reduce emissions of harmful greenhouse gases, while making homes and businesses more comfortable.

[1] The term ‘equivalent’ means that excess annual renewable electricity produced (or interconnected) in East Hampton would be credited (offset) against remaining fossil fuel usage in the transportation and heating sectors.
