Save On Your Power Bill While Reducing Your GHG Emissions

Our homes are significant drivers of greenhouse gas (GHG) emissions, but reducing your carbon footprint is easier than you might think. Purchasing a Stash Energy Heat Pump with built-in energy storage will drastically reduce your energy bill while helping the electricity grid integrate renewable energy more reliably. With more renewables and storage devices on the grid, the overall cost of electricity will drop as we are forced to rely less on expensive GHG-emitting electricity generating stations.
On average, space heating and air-conditioning account for just over half of your home’s total energy consumption. Globally, residential buildings account for 22% of final energy consumption and 17% of emissions. In 2018, 57.2% of US homes used natural gas, heating oil, or propane furnaces, while 39.2% heated their homes electrically.
During electricity demand peak periods — like when we all wake up in the morning and turn on our heat, or when we come home from work and turn on the air-conditioning — utilities rely on GHG-emitting peaker-plants for electricity generation. These daily peaks make it difficult for electric utilities to reliably integrate intermittent renewable energy like wind and solar. If the wind isn’t blowing when people are demanding energy, it isn’t very useful to us — unless we can store that energy in an economical way.
The Stash Energy Heat Pump system pairs a high efficiency cold-climate air-source ductless heat pump with thermal energy storage. Heat pumps are more energy efficient than gas or oil furnaces and boilers, and they play an important role in reducing global emissions — and they are great air-conditioners. Heat pumps provide the most efficient heating and cooling available, producing two to four units of heat or air-conditioning for each unit of electricity used — a gas furnace produces a little less than one unit of heat per unit of energy. Depending on how electricity is generated in the service territory that you live in, over its lifetime, a new conventional air-source heat pump can reduce greenhouse gas emissions by 46 to 54 percent compared to using natural gas.
The electricity grid connects all of us, and the only way that we can reduce our collective emissions is by recognizing how we support the grid.
With the Stash Energy Heat Pump, homeowners now have the ability to store energy for heating or air-conditioning when they — or the grid — need it. By purchasing our system, you're helping your utility rely less on peaker-plants and more on renewable energy sources by storing off-peak energy — like overnight wind power — for use during peak hours. When your family wakes up in the morning your Stash heat pump isn’t heating or cooling your home with electricity from the grid, it's using the wind energy that was generated and stored overnight that had nowhere to go.
Each Stash Energy Heat Pump shifts 7kWh of electricity demand from on-peak to off-peak hours. Using an average generating mix in the United States, if Stash Energy deployed 10,000 units it could shift 70,000 kWh of electricity heating or air-conditioning demand away from peak periods every day. If that displaced demand is met by off-peak renewables like hydro or wind, Stash Energy’s heat pumps can eliminate 180,649 metric tons of CO2e from the atmosphere over the unit's 10-year lifecycle — the equivalent of nearly 420,000 barrels of oil consumed, according to the Environmental Protection Agency’s GHG Equivalencies Calculator. These GHG reductions are in addition to the efficiency savings that are experienced by switching from natural gas heating or window air-conditioning systems to a heat pump.
Because your Stash Energy Heat Pump supports the grid during peak hours, your utility credits your monthly bill. With the Stash Energy Heat Pump, you get to control your temperature setpoint without needing to worry about managing your storage schedule — leave that to us and your utility. By supporting the grid during peak hours, your Stash heat pump saves you money while giving you the peace of mind that you’re doing your part for the environment, too. For example, Stash Energy customers in Massachusetts could receive up to $4,200 in bill credits from their utility by enrolling in existing demand response programs.
By helping increasingly less-expensive renewable energy become more reliable, Stash Energy Heat Pump consumers are also helping lower electricity costs for all ratepayers. When utilities don’t have to build large, centralized, generating stations and can instead invest in distributed renewable energy, those reduced costs can be passed on to ratepayers. One in three households faces a challenge meeting its energy needs. By purchasing a Stash Energy Heat Pump you are helping make energy more affordable for not only yourself, but your neighbours as well.
We don’t think you should have to sacrifice your comfort in order to live sustainably. The Stash Energy Heat Pump reduces your emissions and saves you money – all without affecting the temperature that you like to have your home. Season after season, you’ll see savings while helping more renewable energy come onto the grid.
