Our Renewable Energy Principles

We have a long-term goal of using 100% clean and renewable energy for our global platform. To support this goal, we have identified four principles to help us guide our renewable energy purchasing decisions:

  • Nous privilégions le recours aux énergies renouvelables et à faible émission de carbone
  • Nous privilégions les sources d'énergie locales
  • Nous privilégions les sources d'énergie nouvelles ou récentes
  • Nous recherchons des politiques favorables aux énergies renouvelables lors du choix de l'implantation de nouveaux datacentres

Nos progrès

At Equinix we have a long history of investing in sustainable data centers. In fact Equinix’s energy efficiency program dates back to the dawn of our beginning. In the early 2000s we were cognizant of our choice of construction materials and looked to implement energy efficient components into all of our new builds. More recently we have continued to tackle efficiency, while also increasing our focus on renewable energy both onsite and offsite. As a result of our efforts we have:

  • Increased our global renewable energy total from 30% in 2014 to 43% by the end of 2015
  • Maintained 100% renewable energy in Europe as we have grown
  • Signed Power Purchase Agreements (PPAs) in California, Texas and Oklahoma totaling 330 MW of new solar and wind capacity expected to come online in 2017. These agreements will cover 100% of our North American load when they begin.
  • Invested in onsite deployments of clean energy including solar panels in Singapore and Amsterdam and fuel cells in San Jose, California and Frankfurt
  • Adopted more aggressive regional PUE design targets 8-10% less on average

In 2015 Equinix will meet 43% of its global electricity requirements through renewable energy purchases. This includes 100% certified green power in Europe, onsite generation from solar panels and fuel cells, and renewable generation from bridge renewable energy certificates received through our 105 megawatt (MWac) power purchase agreement in California which is not expected online until 2016. These renewable energy purchases are on top of any renewable energy already distributed through the power grid from our existing utilities and suppliers.

Our gross carbon footprint for 2014 was 1,016,467 metrics tons of CO2 (51% Americas, 25% Asia Pacific, 24% Europe). Factoring in the impact of our renewable purchases in EU, our net carbon footprint for 2014 is 773,289 metric tons of CO2 (67% Americas, 33% Asia Pacific, 0% Europe).

Notre mix énergétique

In 2014, with the continuous expansion of our businesses, Equinix consumed over 2,300 GWh of electricity. We expect our final 2015 totals to total approximately 2,500 GWh or the equivalent of 230,000 average U.S. residential homes.

Our effective 2014 electricity resource mix directly supplied by our utilities and suppliers was:*

  • Americas: Renewables 17%, Coal 27%, Natural Gas 19%, Nuclear 22%
  • Asia Pacific: Renewables 3%, Coal 30%, Natural Gas 40%, Nuclear 7%
  • Europe: Renewables 100% (in addition to utility resource mix: Renewables 22%, Coal 28%, Natural gas 24%, Nuclear 23%)
  • *These percentages are calculated based on specific supplier contracts, utility or supplier specific generation mix where available; as well as reported regional electricity grid mixes. Equinix will continue to progress aligning with the amended Scope 2 Guidance of The Greenhouse Gas Protocol Corporate Accounting and Reporting Standard.

Equinix environmental programs have helped us avoid 13,500 kilowatts of demand annually. That’s the same as taking almost 14,500 cars off the road.


Green Innovation

Our energy efficiency investments since 2011 have help us avoid 32,500 kilowatts of demand annually or approximately 122,000 metric tons in CO2 emissions avoided now every year. That’s the same as taking almost 26,000 cars off the road or enough to power more than 26,000 U.S. residential homes each year.

To help us conserve even more energy in the coming years, Equinix has recently adopted more aggressive regional power usage effectiveness (PUE) design targets for new sites as well as major expansions. These targets are based on an average annual PUE at full load (with redundancy) that meets the definition for PUE Category 3.

Technologies éco-responsables déployées à travers le monde

Datacentres éco-responsables

Les systèmes auto-adaptatifs réduisent la consommation d'énergie et augmentent la capacité de refroidissement à travers une gestion active du débit d'air, reposant sur des capteurs intelligents et distribués et des politiques de contrôle innovantes.

Datacentres éco-responsables

Les directives thermiques ASHRAE servent de référence pour optimiser la température intérieure de nos installations les plus récentes. Ceci permet de réduire la consommation énergétique liée au refroidissement tout en maintenant une température d'exploitation adaptée au matériel informatique.

Datacentres éco-responsables

Le confinement d'allées froides/chaudes repose sur des barrières physiques qui permettent de limiter les mélanges entre l'air froid fourni dans les allées et l'air chaud qui s'évacue de nos datacentres. Cette technique permet de réduire la consommation d'énergie et d'obtenir un refroidissement plus efficace.

Datacentres éco-responsables

Les systèmes d'éclairage écoénergétiques de nos datacentres utilisent des commandes à détection de mouvement pour réduire la consommation d'énergie et la chaleur ambiante provenant des lampes.

Datacentres éco-responsables

Des variateurs de vitesse sont déployés dans les refroidisseurs, les pompes et les ventilateurs de nos système CVC, permettant ainsi d'économiser de l'énergie en réduisant automatiquement la vitesse et la consommation électrique du moteur lorsque la charge du système est moindre.


Éco-innovations dans les centres IBX

Chez Equinix, lorsque nous concevons et construisons de nouveaux datacentres International Business Exchange™ (IBX®), nous tirons parti des conditions propres à chaque site pour réduire notre utilisation d'énergie et notre empreinte carbone. Les exemples ci-dessous illustrent les écotechnologies que nous déployons dans certains de nos datacentres IBX.

  • Stockage d'énergie thermique en aquifère (ATES)

    Stockage d'énergie thermique en aquifère (ATES)

    The ATES system at Equinix's AM3 IBX in Amsterdam uses cold groundwater to help chill air on the colocation floor, eliminating the need for traditional mechanical cooling. When temperatures rise above 18 degrees Celsius (64 degrees Fahrenheit), the ATES system kicks in to keep equipment cool. At other times of the year, AM3 relies on free-air cooling. Excess heat generated by customer's IT equipment is also used to help warm nearby buildings.

  • Refroidissement par eaux profondes

    Refroidissement par eaux profondes

    Equinix's TR1 IBX in Toronto reduces power consumption by using the city's Deep Lake Water Cooling (DLWC) system to draw water from the chilly depths of Lake Ontario to cool buildings in downtown Toronto, including our data center. This novel approach reduces total energy needs by 50% or more.

  • Des économies directes et indirectes

    Des économies directes et indirectes

    In Equinix data centers around the world, we've deployed air and fluid economizers to provide "free cooling" to our colocation space, maintaining temperatures within acceptable ranges while lowering energy consumption. Our economization systems reduce or sometimes eliminate the need to run mechanical cooling systems, which contribute significantly to the energy footprint of any data center. The types of economizers we deploy—direct or indirect, air or fluid (usually water or glycol)—depend on local climate conditions and data center space constraints.

  • Piles à combustible

    Piles à combustible

    Our FR4 IBX in Frankfurt produces approximately 800,000 kilowatt hours of electricity annually through a controlled chemical reaction involving oxygen, hydrogen and water. The power and cooling capacity created by the fuel cell system could reduce FR4's consumption of energy from the grid by 24% and save about 150 metric tons of CO2 emissions each year.

  • Toitures vertes

    Toitures vertes

    By covering roofs with plants and vegetation at our AM3 IBX in Amsterdam and our ZH5 IBX in Zurich, Equinix lowered cooling costs and reduced storm water runoff, which is associated with flooding and the nutrient pollution of nearby lakes and rivers.

  • Énergie solaire

    Énergie solaire

    Solar photovoltaic (PV) systems have been installed at our AM3 (Amsterdam), FR2 (Frankfurt) and SG3 (Singapore) IBX data centers to supplement power from the local grid.

  • Systèmes de contrôle granulaire de la température

    Systèmes de contrôle granulaire de la température

    Equinix's SG1 IBX in Singapore has been retrofitted with a granular temperature control system that has improved the facility's PUE by 15%. Based on SG1's impressive results, this control system is now being installed at several other Equinix data centers, including facilities in Chicago, Hong Kong, Silicon Valley and Sydney.

  • Conception optimisée du point de vue thermique

    Conception optimisée du point de vue thermique

    Equinix's SV5 IBX data center in Silicon Valley incorporates techniques from state-of-the-art refrigeration systems to significantly reduce the power needed to cool the colocation floor. The system uses efficient direct expansion coils, lower fan power through air management approaches and an innovative evaporative condensing system that is more efficient than conventional air-cooled condensers.

  • Recyclage de l'eau

    Recyclage de l'eau

    Several Equinix data centers—RJ2 in Rio de Janeiro, SV2 and SV3 in California's Silicon Valley, SY3 in Sydney and our Ashburn campus in the Washington, D.C., area—use recycled rainwater and/or municipally supplied gray water for landscape irrigation and also sometimes for data center cooling systems.
