Online Gambling and the Environment: What Is Known, What Is Not

Reading time: 7 minutes | Published on March 24, 2026 | Updated: October 2, 2026

Server racks and a laptop symbolising the energy use of online gambling

Online casinos are sometimes described as “green” simply because they need no building, no chips and no paper. The reality is less tidy: every game round, video stream and crypto payment runs on electricity somewhere. This article looks at where that energy goes, what Wettson publishes about it (as of 2 October 2026: nothing), and the few choices a player can actually make. It contains no carbon figures, because neither the operator nor the game studios publish any for this site. Gambling is for adults (18+) and is not a way to make money.

Correction: an earlier version of this article suggested that Wettson used sustainable practices. That was not supported by anything the operator publishes and has been removed.

Where the energy goes

  • Servers and data centres. Accounts, payments and the random number generators of the games run on servers, usually operated by the game providers and hosting companies rather than by the casino brand itself.
  • Live casino streaming. Live tables are filmed in studios with cameras and lighting and streamed continuously as video. A video stream generally carries far more data than the result of a slot spin, so a long live session tends to use more network capacity than the same time on an RNG game.
  • Your own device and connection. Screen, processor and network all draw power, and high-resolution streams draw more.
  • Payments. Card and e-wallet systems run on shared infrastructure; some cryptocurrencies add a much larger energy cost of their own (see below).

Published estimates of the footprint of streaming and data transfer vary widely depending on the method, so this article does not pick a number. The direction is clear enough: more hours and higher video quality mean more energy.

What Wettson publishes on sustainability

On the pages checked on 2 October 2026 — home page and footer (wettson7.com), About (wettson7.com/info/about_us), general terms (wettson7.com/info/terms_and_conditions) and FAQ (wettson7.com/info/faq) — the operator publishes no information on sustainability, green hosting, renewable energy or carbon offsetting. It does not name its hosting provider either. That is common in the industry, but it means any claim that this casino is “eco-friendly” has no source.

The About page does claim “13.000+ games from the BEST providers”. Whatever the real number, the games are hosted by their providers, so the footprint is spread across companies that the casino does not list.

Crypto payments: proof-of-work and proof-of-stake

The cryptocurrencies a network uses matter far more for energy than the casino does. Proof-of-work networks (such as Bitcoin) secure transactions through mining, which consumes large amounts of electricity across the network. Proof-of-stake networks secure transactions through validators who lock up coins, which needs only a small fraction of that energy. Ethereum switched from proof-of-work to proof-of-stake in September 2022 (“the Merge”); according to the Ethereum Foundation this reduced its energy use by orders of magnitude.

The cashier shown on 2 October 2026 (wettson7.com/payments/deposit and wettson7.com/payments/withdraw) lists these crypto options:

Cashier option (as listed)Network typeLimits per transaction
Bitcoin, Bitcoin cash, LitecoinProof-of-workDeposit €25–€5,000; withdrawal €100–€1,000
Ethereum, USD Coin (Ethereum), USDT (Ethereum)Proof-of-stake (Ethereum since September 2022)Deposit €25–€5,000; withdrawal €100–€1,000
USD Coin (Solana)Proof-of-stake (Solana)Deposit €25–€5,000; withdrawal €100–€1,000
USDT (TRON)Delegated proof-of-stake (TRON)Deposit €25–€5,000; withdrawal €100–€1,000

Two caveats from the operator’s own pages. First, the cashier was shown to a visitor located outside the site’s language markets, and the terms state that payment methods depend on country and currency (T&C 59.1), so your list may differ. Second, crypto deposits can trigger a bonus automatically: the Welcome Crypto COMBO (150% up to 1 BTC plus 150 free spins, first crypto deposit from €30) and the 100% Crypto Bonus are both credited automatically, with 40x wagering on the bonus (wettson7.com/promotions/promotions). Read the bonus terms before depositing if you do not want those conditions on your balance.

How much energy a single transaction “causes” on a proof-of-work network is debated, because mining energy is spent per block rather than per payment. What is not debated is that proof-of-stake networks run on far less energy overall.

Paperless verification is standard, not a green credential

Like most online casinos, Wettson handles identity checks digitally. According to its FAQ (wettson7.com/info/faq), documents are uploaded via Icon → My profile → Documents as JPEG, PNG or PDF files of up to 3 MB; accepted documents include an ID card, passport or driving licence and a proof of address issued within the last 3 months. The same FAQ says it “cannot accept mobile screenshots, cropped or scanned files”, yet asks for a screenshot as proof of an e-wallet — a contradiction worth knowing about before you upload. Nothing needs to be printed or posted, which is convenient, but it is the normal way of working online rather than an environmental policy.

What a player can actually do

  1. Keep sessions short and planned. Fewer hours is the single biggest lever for both energy use and spending. Deposit limits per day, week or month can be set via support; decreases apply immediately, increases after 24 hours (wettson7.com/info/responsible_gaming).
  2. Close live tables you are not playing and use a lower video quality where the game offers it.
  3. If you use crypto, prefer a proof-of-stake network (for example a stablecoin on Ethereum, Solana or TRON) over a proof-of-work coin — and remember that crypto prices and network fees carry their own risks.
  4. Do not print documents; upload them in one go in the required format to avoid repeat requests.
  5. Ask — the operator can be contacted at [email protected]. If a casino cannot name its hosting or energy policy, treat “green” claims anywhere on its pages with caution.

How to test a “green casino” claim anywhere

A credible environmental claim names the hosting or data-centre provider, says what share of energy is renewable and who verifies it, explains whether game providers and live studios are included, and says which offset projects are used and by which standard they are certified. Vague words without any of these are marketing. The terms overview on this site summarises what Wettson does publish; the article on VR casinos and what exists today covers formats that would use even more computing power, and the social side of online casinos looks at live-dealer chat and its rules.

Frequently asked questions

Does Wettson use green hosting or renewable energy?

The operator does not say. On the pages checked on 2 October 2026 it publishes no information on sustainability, hosting, renewable energy or carbon offsetting.

Is paying with crypto bad for the environment?

It depends on the network. Proof-of-work coins such as Bitcoin, Bitcoin cash and Litecoin use far more energy than proof-of-stake networks; Ethereum has used proof-of-stake since September 2022. The cashier checked on 2 October 2026 lists both kinds.

Does live casino use more energy than slots?

Generally yes per hour of play, because live tables are filmed and streamed as continuous video, while a slot spin transfers little data. No specific figures are published for Wettson or its game studios.
