Neighborhood geothermal energy

December 30, 2024 By EarthWise Leave a Comment

Residential geothermal energy makes use of the constant, year-round temperature of the earth below the surface to efficiently provide both heating and cooling for a home. In the summer, the cool earth beneath a house sits at about 55 degrees and can be tapped into with a heat pump to provide cooling. In the winter, that 55-degree underground expanse provides a much warmer source of air to heat instead of the often freezing-cold air outside. Geothermal systems are appealing because they use far less energy than other sources of heating and cooling.

Using geothermal energy to heat and cool buildings is nothing new. But after years of planning and months of drilling into the ground, the first neighborhood-scale geothermal heating and cooling project has come online in Framingham, Massachusetts.

The project ties together 31 residential and five commercial buildings that share the underground infrastructure needed to heat and cool them. This sort of shared geothermal system has previously been used on college campuses and similar places, but never before across a neighborhood in the United States.

The $14 million project, built by Eversource, broke ground in June 2023, and comprises 90 boreholes or wells drilled 600-700 feet underground. Approximately 135 customers are connected to the system, including low- and moderate-income customers, apartment buildings, a gas station, and a kitchen cabinet showroom.

A total of 13 states, including Massachusetts and New York, are considering pilot projects or advancing legislation that would allow gas utilities to develop networked geothermal heating and cooling.

Electric Cars And Apartments | Earth Wise

July 10, 2023 By EarthWise Leave a Comment

The transition to electric cars is underway. People are increasingly buying them, carmakers are switching over to making them, and governments are providing incentives as well as legislating the changeover. More and more consumers want to lower their carbon footprints and stop burning fossil fuels. But one very large group of consumers faces an uphill battle in switching to electric cars: people who rent their dwellings.

About one third of our country lives in rented apartments or houses. These nearly 110 million Americans are more likely to be in the bottom half of income and net worth and are more likely to be people of color. These people are less likely to have the spare cash to make upgrades to their property such as car chargers and may not be able to get permission from their landlords to do it anyway.

Renters face what is known as the “split-incentive problem” or the “landlord-tenant problem.” Three-quarters of tenants in the US pay their own utility bills, so they have a strong incentive to conserve electricity, water, and gas. Their landlords, on the other hand, have little incentive to upgrade appliances and systems to be more environmentally responsible. Studies have shown that on average renters use 3% more energy than homeowners for this reason.

There are some landlords who are being proactive and installing facilities for charging cars on their properties. This will undoubtedly become an increasingly sought-after feature for renters. But in the meantime, millions of them have a more difficult time driving electric cars. They can charge at public chargers or perhaps at work. But at the moment, homeowners are three times more likely than renters to own an electric car.

Fumes From Gas Stations

A study by environmental health scientists at Columbia University examined the release of vapors from gas station vent pipes and found that emissions were 10 times higher than the estimates used to establish setback regulations that determine how close schools, playgrounds, and parks can be to the facilities.
