Is geothermal energy available in New York?

Geothermal energy is energy that is generated by heat from within the Earth. It involves using the heat from the Earth’s interior for heating applications like buildings and homes, or for generating electricity. Geothermal energy is a renewable resource that can provide clean and sustainable energy.

The purpose of this article is to provide an overview of geothermal energy and discuss its potential applications in New York State. Specifically, this article will cover the geothermal resources available in New York, existing uses of geothermal energy, the benefits and limitations of the technology, government policies related to geothermal, and the future outlook for geothermal energy in the state. The goal is to analyze whether geothermal energy could be a viable clean energy solution for New York.

Overview of Geothermal Energy

Geothermal energy utilizes the natural warmth of the Earth to provide heat and generate electricity. It is considered a renewable energy source because the heat emanates from the interior of the Earth, largely from radioactive decay and residual heat from the planet’s formation billions of years ago. This heat continuously flows outward towards the surface (Source:

There are three main types of geothermal energy systems:

  • Direct use – This uses naturally heated water from hot springs or reservoirs near the surface for applications like space heating or growing plants in greenhouses. Hot springs have been used for bathing, heating, and cooking for thousands of years.
  • Geothermal heat pumps – These use stable ground or water temperatures near the Earth’s surface to control temperatures in buildings. They transfer heat between the ground and the building, helping provide heating in winter and cooling in summer.
  • Electricity generation – Geothermal power plants use steam from reservoirs sometimes miles beneath the Earth’s surface to drive turbines and generate electricity. This type of energy is available near tectonic plate boundaries, volcanic regions, and other areas with naturally heated water.

In summary, geothermal energy relies on harnessing the Earth’s internal thermal energy either directly or through various technologies to provide heating, cooling, and clean electricity (Source:

Geothermal Potential in New York State

New York has significant potential for growth in geothermal energy. According to the New York City Geothermal Pre-feasibility Tool, around 30% of NYC has high potential for geothermal systems, while 50% has medium potential [1]. Areas with shallower bedrock like Manhattan, western Brooklyn, and parts of Queens are well-suited for geothermal.

Statewide, a 2008 study by the Geological Survey estimated over 9,000 megawatts of geothermal power potential using enhanced geothermal systems (EGS) [2]. The study identified hotspots near Syracuse, Buffalo, Albany, and the NYC metro area. EGS methods can extract heat from bedrock through fracturing, expanding geothermal viability across the state.

Currently, New York has around 120 geothermal installations providing 47 megawatts of capacity. Capacity could grow substantially in the coming years with supportive policies and incentives. Urban areas with high heating demands offer the greatest near-term potential.

Current Use of Geothermal in NY

While geothermal energy is still relatively new in New York, there are some notable installations across the state:

In New York City, the largest geothermal system is being built as part of a new residential tower development in Coney Island. This system will have over 500 geothermal wells drilled to provide heating and cooling for two 49-story towers with over 1,100 apartments (Source).

Cornell University has installed geothermal systems in over 20 buildings on campus, including residences, academic buildings, and athletic facilities. Their combined capacity is over 5,000 tons of cooling (Source: NYS Clean Heat).

In the Hudson Valley, the Stone Barns Center for Food and Agriculture uses a ground source heat pump system to heat and cool their educational facilities. This system provides over 300 tons of heating and cooling capacity (Source: NYS Clean Heat).

Other notable geothermal installations in NY include the Bronx Zoo, the NYS Museum in Albany, and dozens of K-12 schools across the state. Total installed geothermal capacity in NY is estimated at over 10,000 tons statewide as of 2020, but is growing rapidly each year.

Benefits of Geothermal Energy

Geothermal energy provides several key benefits compared to conventional fossil fuel energy sources. Some of the main advantages of using geothermal energy include:

  • Environmental benefits – Geothermal energy is considered a renewable energy source and does not burn fossil fuels. This makes it a clean energy source that does not contribute to air pollution or greenhouse gas emissions. According to the U.S. Department of Energy, geothermal power plants emit on average 99% less acid rain-causing sulfur compounds and 98% less smog-causing nitrogen oxides compared to fossil fuel plants. Additionally, geothermal plants emit significantly lower amounts of carbon dioxide, a major greenhouse gas (U.S. Department of Energy).
  • Economic benefits – Geothermal power plants have low operational costs as they do not require fuel sources to operate. The plants have long operating lifetimes, low maintenance needs, and high availability (90-98%), helping lower operating costs. Geothermal also provides a stable base load energy source not affected by market fluctuations in fuel prices (Enel Green Power).
  • High efficiency – Geothermal power plants can achieve high capacity factors averaging around 90-95% as they can operate continuously to provide base load power. This is much higher than intermittent renewable sources like wind and solar which rely on variable resource availability (U.S. Department of Energy).

Overall, geothermal energy provides a clean, renewable baseload energy source with economic advantages from low operating costs and high efficiencies.

Geothermal energy has several drawbacks and challenges that have limited its growth and adoption in many parts of the United States and around the world. Some of the key limitations and challenges include:

Limitations and Challenges

High Upfront Costs: Constructing a geothermal power plant requires substantial upfront capital investment compared to conventional power plants. According to one analysis, the initial cost for a geothermal power plant in 2020 averaged between $2,500 to over $5,000 per installed kW capacity, which is significantly higher than natural gas at under $1,000 per kW ( These high upfront costs can deter investment and widespread adoption.

Site-Specific Limitations: Geothermal energy can only be harnessed in geographically favorable locations with ideal hot rock formations and hydrothermal resources. This means geothermal potential is restricted based on subsurface geology, with the western half of the U.S. often having the most potential. The site-specific nature limits where geothermal plants can be built (

Lack of Awareness: There is generally low public awareness and understanding of geothermal energy and its potential benefits. The geothermal industry has not done enough educational outreach and advocacy compared to other renewable sources like solar and wind. This lack of knowledge has slowed policy support and adoption for geothermal power (

Government Policy

The New York State government offers incentives to promote the adoption of geothermal energy systems. The most significant incentive is a 25% tax credit on the cost of installing a geothermal system, up to $5,000. This can help offset the high upfront costs of installing geothermal heat pumps.

At the federal level, homeowners can claim a 26% tax credit for installing a geothermal system until the end of 2032. There are also special tax credits for commercial geothermal installations.

The New York State Energy Research and Development Authority (NYSERDA) offers various rebates and incentives for renewable energy systems, including geothermal. They have a residential rebate program that provides up to $1,200 per ton of capacity for ground source heat pumps.

Additionally, some utility companies like National Grid offer rebates on top of NYSERDA incentives for installing geothermal systems. All of these initiatives make geothermal more affordable for New York homeowners and businesses.

Future Outlook

Experts project strong growth for geothermal energy in New York in the coming years. According to a report by the New York State Energy Research and Development Authority (NYSERDA), geothermal capacity could expand by over 9 times in New York by 2030 under an optimistic scenario. This would represent an increase from around 130 megawatts (MW) of installed capacity today to 1,200 MW by 2030.

Several key factors are expected to drive growth:

– Policy support – New York’s climate plan calls for a transition to 100% clean electricity by 2040. The state is providing incentives and programs to encourage geothermal adoption.

– Cost declines – As the geothermal market expands, costs are projected to decrease, improving the economics.

– Innovations – Advances in areas like co-production with hydropower could unlock new potential.

– Increased consumer awareness – More homeowners and businesses are learning about geothermal benefits.

However, meeting the optimistic projections will require overcoming persistent barriers like high upfront costs and lack of infrastructure and trained personnel. Targeted policies and incentives will be needed to catalyze growth and drive innovation in New York’s nascent geothermal energy industry.

Case Studies

New York has seen several successful large-scale geothermal projects in recent years that demonstrate the viability and benefits of this technology in the state. One prominent example is the geothermal system installed at the New Central High School in DeWitt, NY. This project utilized 400 geothermal wells drilled to a depth of 500 feet to provide heating and cooling for the 220,000 square foot building. It is estimated to save the school $150,000 annually in energy costs compared to conventional HVAC systems.

Another major project was the geothermal heat pump system installed at the iconic St. Patrick’s Cathedral in New York City. This system leverages 104 geothermal wells drilled in Manhattan to provide an energy-efficient, cost-effective and sustainable way to heat and cool the historic cathedral. It is projected to reduce CO2 emissions by more than 94,000 tons over 30 years.


In summary, geothermal energy does show potential for expanded use in New York state. While geothermal resources are limited compared to other renewable energy sources, new technologies like enhanced geothermal systems are making deeper geothermal resources more accessible. Key geologic locations, like parts of the Finger Lakes region, demonstrate there are viable sites for geothermal in the state.

With the right policy support and technological innovations, New York could further develop geothermal to diversify its energy portfolio with a clean, renewable baseload resource. More demonstration projects and feasibility studies mapping the geothermal potential across the state will help attract investment and project development. Overall, geothermal energy in New York may play a small but meaningful role in the statewide transition to carbon-free power generation.
