What you could gain

  1. Low-carbon heating53/100

    ~$1,351/yr

    less heating after insulation + heat pump (−8,190 kWh/yr on 90 m², electric heating)

    The detail

    Realistic outlook

    2,630 heating-degree-days: a high-efficiency heat pump is the lowest-carbon way to keep New York warm.

    Watch-outs

    A heat pump only pays off in a well-insulated envelope — insulate first, then size the unit.

    Incentives & tips

    Energy Efficient Home Improvement Credit (§25C): up to $2,000/yr for heat pumps plus credits for insulation; HEEHRA state rebates may stack.

  2. Food growing65/100

    ~$784/yr

    off the weekly shop — up to ≈280 kg/yr of fresh vegetables from 100 m²

    The detail

    Realistic outlook

    With about 244 frost-free days, a household garden in New York supports two planting rotations a year.

    Watch-outs

    A productive garden needs space, decent soil and a few hours a week — start small and scale up.

    Incentives & tips

    USDA People's Garden and many municipal community-garden and composting programs support home food production.

  3. Solar energy37/100

    ~$526/yr

    less electricity with 3 kWp on your roof (≈4,044 kWh/yr)

    The detail

    Realistic outlook

    At 1,348 kWh/kWp per year, New York offers moderate potential for residential rooftop solar.

    Watch-outs

    Roof orientation, shading and local interconnection rules affect real output — get a site assessment first.

    Incentives & tips

    Federal Residential Clean Energy Credit (IRA §25D): 30% tax credit on solar PV and battery storage through 2032.

  4. Rainwater90/100

    ~$200/yr

    less mains water with a 5,000 L tank (≈111,520 L/yr harvestable from a 100 m² roof)

    The detail

    Realistic outlook

    1,312 mm of rain a year makes rooftop rainwater harvesting highly productive in New York.

    Watch-outs

    Harvested rain is non-potable by default — keep it separate from drinking water and add a first-flush diverter.

    Incentives & tips

    Rainwater incentives vary by state — e.g. Texas sales-tax exemption on harvesting equipment, local rebates in Arizona. Check state and city programs.

Local context

What is specific to New York

Brownstones line the streets of Park Slope, Fort Greene and Harlem. In historic districts, exterior work answers to the Landmarks Preservation Commission, which regulates more than 38,000 landmark properties, most in 157 historic districts. Under its rules in effect since July 2024, staff can approve flat-roof solar arrays that are only minimally visible from the street. Panels on a front- or side-facing pitched slope need proof that other spots lack enough sun, must stay off slate or clay tile, cannot go on an individual landmark and, if visible, should generally be black-on-black.

Local Laws 92 and 94 of 2019 require new buildings, and buildings replacing an entire roof deck or assembly, to cover their sustainable roofing zone with solar panels, a green roof or both; cisterns and blue roofs built to Department of Environmental Protection (DEP) guidelines are left out of that zone. For solar or batteries placed in service from 2024 through 2034, a property tax abatement is worth 30 percent of installation cost, up to $250,000, spread over four years. Installers file through the Department of Buildings; applications received by March 15 take effect that year.

Local Law 154 of 2021 bans burning fossil fuels on site in new buildings: since 2024 for one- and two-family homes and most buildings under seven stories, and for all new buildings from July 2, 2027. Local Law 97 caps emissions for most buildings over 25,000 square feet; owners of smaller ones can get free advice from NYC Accelerator. Con Edison's steam system, running since 1882, covers Manhattan below 96th Street on the West Side and 89th on the East Side. Under the state's 2026–2030 utility orders, the company's Clean Heat program serves only one- to four-family homes.

Water comes from DEP's upstate Catskill, Delaware and Croton reservoirs. The city declared a drought watch on November 2, 2024, raised it to a warning on November 18, eased it back to a watch on December 16 and lifted it on January 3, 2025. The dry spell forced DEP to pause its $2 billion repair of a Delaware Aqueduct leak under the Hudson River; it now expects to resume in 2031. DEP cuts water charges by 25 percent for buildings whose reuse systems lower consumption by at least a quarter.

NYC Parks GreenThumb, founded in 1978, supports more than 550 community gardens, most of them once-abandoned lots. Each is volunteer-led and self-governing, open to the public at posted hours from April to October. Most still water from fire hydrants; a 2022 federal award of more than $46 million will fund water connections at over 200 food-producing gardens by the end of 2030. Since April 1, 2025, owners can be fined for not separating food scraps and yard waste from trash, and from April to September the Department of Sanitation gives residents free bags of compost.

Local climate

Climate month by month in New York

In New York, a 3 kWp array pitched at 37° and facing 6° east of south — the optimum PVGIS computes for this location — produces about 4,044 kWh a year. July is the strongest month, at about 402 kWh, and December the weakest, at 222 kWh. November to February still bring 26% of the year's output, so the system stays useful all winter and a battery pays its way year-round.

The heating season runs from October to April: 7 months average below 59 °F (15 °C), and January is the coldest at 32 °F (-0.1 °C). In a typical year the coldest hours drop to about 16 °F (-9 °C), the point a heat pump has to be sized for: a standard air-to-water heat pump copes comfortably in an insulated house.

Frost is possible until late March and returns from late November, which leaves about 244 frost-free days; tender crops such as tomatoes, beans and squash go outside once late March is past. About 23 days pass 86 °F (30 °C), so water early in the morning during heatwaves.

With a mean wind of 8 mph (3.6 m/s) at 10 m, a small rooftop turbine would produce little in New York; the roof is better used for solar. PVGIS's elevation model puts the southern horizon up to 15.7° high — terrain or tall buildings — which trims the low winter sun, so check shading on site before choosing panels.

Compared with Philadelphia, 81 miles away, New York has 1% less solar yield, 26 more frost-free days and a heating need 2% higher. Compared with Baltimore, 169 miles away, New York has 2% less solar yield, 6 more frost-free days and a heating need 7% higher.

Frequently asked questions — New York

How much could solar panels generate in New York?

A well-oriented 3 kWp rooftop array in New York produces about 4,044 kWh a year, worth roughly $526 in self-consumption. A 6 kWp system reaches about 8,088 kWh/yr where the roof allows. Federal Residential Clean Energy Credit (IRA §25D): 30% tax credit on solar PV and battery storage through 2032.

Is rainwater harvesting worth it in New York?

Yes. A 60 m² roof in New York can capture about 66,912 litres a year for the garden, WC and washing machine. Keep harvested rain separate from drinking water and fit a first-flush diverter. Rainwater incentives vary by state — e.g. Texas sales-tax exemption on harvesting equipment, local rebates in Arizona. Check state and city programs.

What grants help with low-carbon heating in New York?

Energy Efficient Home Improvement Credit (§25C): up to $2,000/yr for heat pumps plus credits for insulation; HEEHRA state rebates may stack. Insulate first — a heat pump only pays off in a well-insulated home (2,630 heating-degree-days here), so prioritise the roof and walls before sizing the unit.

How much food can a garden grow in New York?

With about 244 frost-free days, a 100 m² garden in New York yields roughly 280 kg of fresh fruit and vegetables a year — a partial share of a household's needs, not full calorie autonomy. USDA People's Garden and many municipal community-garden and composting programs support home food production.

When is the last frost in New York?

Frost is possible until late March and returns from late November, which leaves about 244 frost-free days; tender crops such as tomatoes, beans and squash go outside once late March is past.

How much does solar produce in winter in New York?

December is the weakest month: a 3 kWp array makes about 222 kWh, against 402 kWh in July. November to February add up to 26% of the yearly total.
