    What you could reach in Denver

    • ≈174 days a year off the grid — keep the fridge, lights, router and heating pump running straight from your own roof and battery, right through a winter outage.
    • Rainwater self-reliance — ≈68,000 L harvested from a 100 m² roof covers the garden and toilet flushing, so hosepipe bans stop mattering.
    • A real harvest — ≈180 kg of fresh vegetables over a ≈155-day frost-free season takes a genuine bite out of the weekly shop.
    • A warm, low-bill winter — insulation plus a right-sized heat pump turns the local climate into low-carbon comfort and shields you from gas-price spikes.

    Solar energy

    Growing

    40/100
    Realistic outlook
    At 1,610 kWh/kWp per year, Denver 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.
    Technical details

    Annual PV yield : 1,610 kWh/kWp.

    Rainwater

    Growing

    56/100
    Realistic outlook
    800 mm of rain a year makes rooftop rainwater harvesting worthwhile in Denver.
    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.

    Food growing

    Growing

    38/100
    Realistic outlook
    With about 155 frost-free days, a household garden in Denver 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.
    Technical details

    Frost-free growing season : ≈ 155 days.

    Low-carbon heating

    Growing

    31/100
    Realistic outlook
    3,330 heating-degree-days: a high-efficiency heat pump is the lowest-carbon way to keep Denver 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.

    energy autonomy

    Indicative estimate (production = kWp × local yield). Real output depends on roof orientation, shading and your self-consumption rate.

    Denver: 42/100 achievable autonomy with a recommended setup.

    A typical home in Denver can reach about 42% self-sufficiency with a right-sized solar, storage, rainwater and low-carbon heating setup — most of it backed by federal tax credits. The figure sharpens once you enter your own home.

    Public climate data (PVGIS, NOAA, USDA) weighted by how vital each dimension is. The score sharpens once you enter your own home. See the full methodology.

    Frequently asked questions — Denver

    How much could solar panels generate in Denver?

    A well-oriented 3 kWp rooftop array in Denver produces about 4,830 kWh a year, worth roughly $628 in self-consumption. A 6 kWp system reaches about 9,660 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 Denver?

    Yes. A 60 m² roof in Denver can capture about 40,800 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 Denver?

    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 (3,330 heating-degree-days here), so prioritise the roof and walls before sizing the unit.

    How much food can a garden grow in Denver?

    With about 155 frost-free days, a 100 m² garden in Denver yields roughly 180 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.
