Carbon footprint
Yearly emissions by energy source
Based on the rig's annual power draw and the carbon intensity of common grid mixes.
| Energy source | CO₂e / yr |
|---|---|
| Wind | 92.19 kg |
| Nuclear | 100.57 kg |
| Hydroelectric | 201.14 kg |
| Geothermal | 318.47 kg |
| Solar | 377.14 kg |
| Biofuels | 1,927.58 kg |
| Gas | 4,106.59 kg |
| Coal | 6,872.26 kg |
Estimates only — actual emissions vary by hardware, cooling, and grid mix.
What does that actually mean?
At the world-average grid intensity of about 475 g CO₂e/kWh, Antminer Z9 running 24/7 for a year releases about 3,981 kg of carbon dioxide equivalent. Here's what that looks like in everyday terms:
Driving a gas car
9,854 mi
EPA average passenger car emissions ≈ 404 g CO₂/mile.
Trees to absorb it
180 trees
A mature tree absorbs roughly 22 kg CO₂ per year.
Household electricity
1.0 yrs
Equivalent to the yearly emissions of an average household's electricity.
Where you plug in matters
Electricity is not one thing. A kilowatt-hour from a coal plant carries roughly 820 g of CO₂; the same kilowatt-hour from a hydro reservoir carries about 24 g. That's a 34× difference — large enough that Antminer Z9's annual footprint swings from roughly 6,872 kg on coal-heavy grids down to about 201 kg on hydro-dominated grids. The single biggest lever a miner has on their carbon footprint is choosing where to plug in.
Regions commonly used for low-carbon crypto mining include Quebec and British Columbia (hydro-dominated, typically <50 g CO₂/kWh), Iceland and Norway (geothermal + hydro, often <30 g), Paraguay (Itaipú hydro), and parts of the US Pacific Northwest. Coal-heavy grids — Kazakhstan, Inner Mongolia, Poland, parts of Australia — sit at the opposite end, often above 700 g CO₂/kWh.
Some operators also reduce their net impact by using otherwise-wasted energy: flare gas at oil wells (burning methane that would be vented anyway), curtailed renewables (wind or solar that the grid can't absorb), or behind-the-meter hydro during off-peak hours. These arrangements can drop effective emissions below the local grid average because the energy would have been wasted or flared without the mining load.
How to reduce this rig's footprint
- Pick a greener ASIC. The efficiency column above matters as much as the grid: a 15 J/TH rig emits roughly half the CO₂ of a 30 J/TH rig for the same hashrate.
- Choose a low-carbon host. Data centres advertising hydro, geothermal, or nuclear power typically sit at <100 g CO₂/kWh.
- Look for stranded or curtailed energy. Flare-gas miners, wind-curtailment co-location, and off-peak hydro arrangements use energy that would otherwise be wasted.
- Use heat recovery. Capturing the heat for greenhouse agriculture, pool heating, or district warmth offsets fossil-fuel heating that would have been burned anyway.
- Time-shift your uptime. In grids with high daytime solar, running more during the day and less at night lowers your effective intensity even if you don't switch providers.
- Purchase verifiable offsets. Treat this as a last resort, not a substitute — and favour additional, permanent, third-party-verified projects (Gold Standard, Verra VCS).
Frequently asked questions
How do you calculate these numbers?
Yearly electricity use = rig power (W) × 24 × 365 ÷ 1000. We multiply that by each row's grid intensity in grams CO₂-equivalent per kWh and convert to kilograms. Intensities are representative averages — real emissions depend on your specific utility mix, time of day, and local transmission losses.
Is crypto mining bad for the environment?
It depends almost entirely on where the electricity comes from. A single rig plugged into hydro in Quebec emits less over a year than an average family's two cars in a month. The same rig on a coal-dominated grid can exceed that in a few days. The hardware is the same — the grid is what changes the answer.
What about the Bitcoin network as a whole?
Network-wide estimates vary by methodology; the Cambridge Centre for Alternative Finance's Bitcoin Electricity Consumption Index is the most widely cited reference. As of recent reporting, the network's sustainable-energy share has grown as more hashrate migrates to hydro, wind, solar, and stranded-gas sites. This page just estimates a single rig — for the big picture, CCAF's dashboard is the best source.
Do pool fees or mining difficulty affect the footprint?
Not directly. The rig draws the same wattage regardless of which pool it joins or how difficulty trends — so its electricity use, and therefore its emissions, stay constant. Those factors change revenue, not power consumption.

Frequently asked
About the Antminer Z9
Is the Antminer Z9 profitable?
As of April 2026, the Antminer Z9 earns $-0.79/day mining Equihash at an electricity cost of $0.1/kWh. At this electricity rate it is not profitable.
How much power does the Antminer Z9 use?
The Antminer Z9 consumes 970W of power. At $0.1/kWh, that costs approximately $2.33/day in electricity.
Can the Antminer Z9 earn from AI rental?
No. The Antminer Z9 is a mining ASIC — it has no general-purpose compute cores and cannot run AI workloads. AI rental is a GPU-only income mode.
What crypto algorithms can the Antminer Z9 mine?
The Antminer Z9 can mine 1 algorithm(s); Equihash is its most profitable, generating $1.54/day in direct mining revenue before electricity costs. Pool-based mining is the traditional approach — you point the rig at a mining pool and receive payouts in the native coin.
Can the Antminer Z9 sell hashrate on NiceHash?
Yes. NiceHash and similar hashrate marketplaces (Mining Rig Rentals, etc.) let the Antminer Z9 sell its Equihash hashpower directly — buyers rent the compute, you receive BTC per hash delivered. It is similar to mining, but removes coin-price risk since you are paid in BTC on NiceHash's rate.
