CO2-free power from regenerative energy sources and energy-optimized technology



Climate protection and energy efficiency are two important subjects for Europe's biggest rendering farm, the REBUSfarm. By constantly increasing the capacity of our render nodes, not only do we reach a higher cost-efficiency for our customers, but we are lowering the energy consumption per rendering hour as well. Furthermore we are acquiring our power as green electricity from the Naturstrom AG, Düsseldorf. This award-winning green electricity is produced from 100% CO2 and atomic waste free energy sources. The energy mix consists of water- and wind-energy, biomass and solar energy. Adding to that REBUSfarm stands up for the expansion of production capacities for regenerative electricity, and its share in the energy mix to get increased. In the highly competitive market of rendering services, this climate friendly approach is ground-breaking.


Against cost explosion and growing energy consumption

Energy consumption and costs have grown, a tendency that will continue in the coming years. Costs for electricity turn out to be an essential factor in IT-structures. That's why rendering services consistently choose cheap energy, produced by controversial nuclear power plants or the CO2-generating combustion of fossil fuels. But short-term saving of costs doesn't solve the problem: To be competitive in the long term, IT-service providers have to increase their energy efficiency. REBUSfarm does this in three essential areas: hardware, cooling and management software.


Highly efficient hardware lowers the energy consumption

REBUSfarm buys its hardware with focus on the newest energy-saving technologies and only uses CPUs with high processing-density, to optimize the energy consumption per rendering hour. Thus superficially inexpensive technology, like old dual- or even single-core CPUs, are already disqualified. Compared to other providers we save up to 75% energy per CPU.


Cooling without air-conditioning

By doing without the usage of air-conditioning in our computing center we are gaining an essential advantage in energy efficiency. An elaborate cooling concept of hour nodes allows us to do without the energy guzzler no.1: the air con.


Intelligent software management

Performance-optimized, custom-tailored software results in important but unobvious energy-savings. Not only does our intelligent software management keep our customers away from nasty surprises with their rendering results, it also reduces unnecessary energy-consumption by avoiding redundant renderings. Our development endeavors aim at the best possible efficiency to advantage both our customers and the environment.


Designing the future in an ecology-minded way

In 2008 REBUSfarm achieved 50 percent energy-savings per render-hour. To continue with this trend we are constantly working on upgrading and developing new, energy-saving technologies. This has a positive effect on the companies balance, the customer's purse as well as the environment. But that's not enough: Thanks to the Naturstrom AG, as of 2008 the company runs on 100% CO2 and nuclear waste free energy, in spite of drastic price cuts for the customers. Hence it's obvious: When you choose REBUSfarm, you are deciding environment-friendly, while saving hard cash.
