At LRob, we believe that the operation of a website should not weigh on the planet.
This is why we have adopted a green web hostingaligned with the principles of sustainable developmentwithout compromising on performance.
Is eco-friendly web hosting possible?
Behind the scenes, every website requires storage spacethe processor resource and consumes bandwidthon machines that run day and night.
The result: without special care, energy consumption can skyrocket, resulting in emissions greenhouse gas emissions on the rise, an environmental impact which is growing at the same rate as our carbon footprint...
And our planet suffers.
While some people are content with greenwashing, we take concrete action by providing solutions.
Your hosting provider has a responsibility in terms of digital sobriety. And so do you, by choosing eco-friendly solutions.
LRob, a company based in France, didn't wait to react. Our commitment to the environment has always been part of our DNA.
We use two main levers for reducing the ecological footprint :
- Choice of datacenter and physical machines Infrastructure modern, eco-efficient, using renewable energies
- Intelligent server management : Optimize every watt for do more with less: an innovative solution that minimizes electricity consumption while maximizing efficiency.
So yes, a eco-friendly accommodation is possible: it combines efficiency and sobriety.
Fewer resources, more results for you
Choosing a green web host isn't just a gesture for the planet: it's a strategic choice for your business.
The choice of a lightweight, optimized infrastructure
Streamlined, efficient infrastructure means less server overload, faster response times and sites that load in a flash.
Result: best user experience, better Google search engine optimization (SEO), better conversions.
And since our servers consume less power, your costs remain reasonable, allowing you to achieve service excellence while reducing your budget. Sometimes, being green can be cost-effective. You gain in performance, visibility and commercial impact, while reducing your ecological impact. You also gain the satisfaction of doing the right thing.
🔄 The virtuous circle of eco-responsible web hosting
Every step of the LRob hosting process is designed to create a winning cycle:
- We start with optimize each server and we optimizes websites (simple site & server architecture, caching, bot blocking)...
- This reduces consumption (CPU, bandwidth)...
- This frees up resources for better performance...
- And enables energy and cost savingsreinvested in new optimizations.
💡 Result: less environmental impact, more concrete results for your business.
A real virtuous circle. And at LRob, it works for you 24 hours a day.
Datacenter 100% green energy = host green
LRob has chosen for you one of the world's most efficient data centers100% green energy: Hetzner
This data center boasts an exceptional PUE (Power Usage Effectiveness) of 1.13.
PUE measures the energy efficiency of data centers. The closer this value is to 1.0, the higher the efficiency.
In 2024, the average PUE worldwide is 1.56. The European average in 2020 was 1.46. OVH's average PUE is 1.26 over a period between 2023 and 2024.
Optimum energy performance for a responsible digital future
Achieving a PUE of 1.13 requires multi-disciplinary intelligence and coordination right from the design stage.
Result: a energy saving multi-factorial: from the design of the datacenter for natural air cooling 98% of the year, to the optimization of physical servers to consume less.
Energy 100% renewable
Powered by hydroelectricity, our datacenter uses exclusively renewable energy sources.
Natural air cooling
Very little air conditioning for our eco-friendly servers. 98 % of the time, Hetzner cools its data centers withexternal air (free cooling), without mechanical air-conditioning: a cool geographical location, a cold/warm aisle layout and a saw-tooth roof that encourages air flow, avoid the need for year-round air-conditioning.
Optimizing physical servers
With a view to conserving resources, our servers are designed on a modular basis, with no superfluous chassis, and every unnecessary component is removed as soon as the customized production run has been completed.
The result: considerable savings on materials, and an immediate reduction of 50 watts per machine. It's cheaper and greener, right from the design stage.
Our partner Hetzner
We've found this high-performance, eco-responsible design quality in our German partner Hetzner.
The European evolution of the PUE shows us that we have made the right choice with Hetzner, which has a clear lead in energy optimization.

Server optimization by LRob
At LRob, we know that software optimization can make all the difference. Through a simple and efficient architecture, where every configuration is carefully thought out, we save resources and energy, for maximum performance. The fight against robots in particular saves up to 95% of CPU.
The processor (CPU) is the component that performs all the calculations and consumes the most energy in a server.
How do we reduce CPU load?
This can save up to 100 watts per server at any one time.
It all starts with the fine-tuning of each server software and the rigorous optimization of each website. By caching files, databases and web pages, we significantly reduce load.
But the real stroke of genius comes from our ability to effectively block attacks. Over and above the security benefits for your online services, this approach to reducing processor utilization saves energy and physical machines.
It is estimated that 95% of processor load is saved by these efficient blocking operations. This directly translates into 95% more available resources. For the most heavily-attacked sites from hosts with limited computing resources, the gain in response time is drastic and immediate.
Simple server architecture
At LRob, we apply the "KISS" principle: Keep It Simple Stupid.
Why complicate things?
The simpler the architecture, the more stable it is, and the greater the energy savings. You don't need a cluster of 15 machines to host a site.
Our approach: Excellent, finely configured servers. This is more efficient and effective, avoiding latencies between cluster elements and limiting the risk of breakdowns.
MySQL optimization
For databases, we always use the very latest versions of MariaDB, so we're at the cutting edge of native optimization. What's more, our database servers are optimized to hold databases directly in RAM, with a finely-tuned cache. This drastically speeds up processing and considerably reduces CPU load. Here again, we combine energy savings with performance gains.
Website optimization
A poorly optimized website can use far more resources than necessary. That's why we contact our customers on a case-by-case basis to offer optimization advice. For WordPress, we can even apply these optimization measures directly for you.
In this way, we prevent sites from wasting resources and performance.
Use VPS whenever possible
VPS servers are both economical and ecological, pooling resources while offering excellent availability. That's why all small LRob application and infrastructure servers, such as DNS servers, run on VPS. This delivers more than sufficient performance for lightweight applications, and saves energy.

FAQ
What are the criteria for choosing a green host?
An eco-responsible web hosting provider can't be decreed, it has to be demonstrated. Here are the points to check before entrusting your site to someone:
- ✅ Energy 100 % renewable with clear, audited guarantees of origin.
- 🌬️ Optimized cooling The new air-conditioning: outside air rather than energy-hungry air-conditioning.
- 🔁 Reusable, reconditioned or recycled equipment : priority given to equipment durability.
- 🌍 Datacenters close to your users to limit distances and bandwidth.
- 📉 Digital sobriety policy no unnecessary oversizing, efficient resource sharing.
- 📜 Transparency and proof published figures, available audits, recognized labels or certifications (ISO 27001, European code of conduct, etc.).
- 🚫 No greenwashing Beware of vague promises without supporting data.
How do I transfer my site to an eco-friendly web host?
Good news: at LRob, we offer you migration. You don't touch a thing, we take care of everything: site, database, e-mails, DNS, SSL certificates. Everything is done without interruption and with full verification.
To understand what's going on under the hood, here are the key steps to transferring to your new LRob hosting :
- 🌐 DNS preparation For example, you can prepare to lower your TTL and/or recopy your DNS zone, so that the change of host is instantaneous afterwards.
- 📦 Exact copy of your data Site files, database, e-mails... via FTP, SSH, IMAP.
- ⚙️ Hosting configuration PHP version, SQL identifiers, WordPress instance detection.
- 🔎 Pre-access test We check that everything is running smoothly before finalizing the migration.
- 🌐 DNS modification to ensure that your domain name actually points to LRob.
- 🔒 SSL/TLS certificate generation We generate a Let's Encrypt certificate to secure exchanges.
- 🔎 Tests We're here to help you: navigation, forms, e-mailing... everything has to work, and we'll test it with you and help out if necessary.
- 🔀 Domain name transfer If you have a .fr domain name, it can be included in the LRob offer.
- ✅ Cancel your old hosting once the migration has been validated.
You can do it yourself if you like, but if it's too much for you, we'll take care of it, at no extra cost - it's included in the package.
What is the ecological impact of bandwidth?
The more bandwidththe more network equipment (routers, switches, fiber optics, etc.) and servers it mobilizes to respond to requests - which increases the cost of the network. overall energy consumption all along the chain, from the datacenter to the end-user terminal.
A poorly optimized or data-hungry site can have a much heavier footprint than it appears, with each request consuming several watts for several seconds.
At LRob, the sites we design are optimized at source (caching, compression, lightweight files) and for all of them, attacks are blocked upstreamwhich drastically reduces (95%) non-legitimate traffic.
👉 Fewer parasitic requests, less data to transfertherefore less bandwidth required = less activated equipmenttherefore less energy consumption.
With LRob, your site consumes less unnecessary bandwidth, and goes faster.
The result: less energy wasted, fewer resources activated, and a lighter environmental footprint - without compromising on performance.
