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:

  • Wir präferieren den Einsatz erneuerbarer und kohlenstoffarmer Energiequellen
  • Wir fördern die Nutzung lokaler Energiequellen
  • Wir bevorzugen neue oder neu errichtete Energiequellen
  • Wir verfolgen bei der Platzierung neuer Rechenzentren Richtlinien für den Energiebezug aus günstigen und erneuerbaren Quellen

Unsere Fortschritte

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
  • Hundertprozentige Nutzung erneuerbarer Energien bei Wachstumsprojekten in Europa
  • 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
  • Regionale Designvorgaben für eine Optimierung der Power Usage Effectiveness (PUE) um 8 bis 10 % im Vergleich zum Durchschnitt

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).

Unser Energiemix

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:*

  • Nord- und Südamerika: Erneuerbare Energien 17 %, Kohle 27 %, Erdgas 19 %, Atomkraft 22 %
  • Asien-Pazifik: Erneuerbare Energien 3 %, Kohle 30 %, Erdgas 40 %, Atomkraft 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.

Nachhaltige Technologien weltweit im Einsatz

Nachhaltige Rechenzentren

Adaptive Kontrollsysteme reduzieren den Energieverbrauch und erhöhen die Kühlkapazitäten durch ein aktives Luftstrom-Managementsystem, das intelligente verteilte Sensoren und innovative Kontrollrichtlinien einsetzt.

Nachhaltige Rechenzentren

Die Richtlinien der American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) werden als Referenz für die Optimierung der internen Temperaturen in unseren neusten Rechenzentren eingesetzt. Dadurch lässt sich der Energiebedarf für die Klimatisierung reduzieren, ohne die sicheren Betriebstemperaturen für das IT-Equipment zu beeinträchtigen.

Nachhaltige Rechenzentren

Die Kalt-/Warmgangeinhausung verwendet physische Barrieren, um die Vermischung von kalter Zuluft und warmer Abluft zu reduzieren. Dies sorgt für einen geringeren Energieverbrauch und eine effizientere Kühlung.

Frequenzumrichter kommen in Kältekompressoren, Pumpen und Ventilatoren unserer HVAC-Systeme zur Senkung des Energieverbrauchs zum Einsatz, indem sie automatisch die Drehzahl eines Motors und damit dessen Leistungsaufnahme reduzieren.


IBX Umwelt-Innovationen

Bei der Entwicklung und Errichtung neuer International Business Exchange™ (IBX®) Rechenzentren setzt Equinix - ausgerichtet an den individuellen Standortbedingungen - Technologien und Prozesse ein, um den Energieverbrauch und den Ausstoß an Kohlenstoffen zu minimieren. Die folgenden Beispiele zeigen den Einsatz nachhaltiger Technologien in ausgewählten IBX-Rechenzentren auf.

  • Aquifer Thermal Energy Storage (ATES)

    Aquifer Thermal Energy Storage (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.

  • Deep Lake Water Cooling

    Deep Lake Water Cooling

    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.

  • Direkte und indirekte Einsparungen

    Direkte und indirekte Einsparungen

    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.

  • Brennstoffzellen


    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.

  • Begrünte Dachflächen

    Begrünte Dachflächen

    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.

  • Solarenergie


    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.

  • Granulare Temperaturkontrollsysteme

    Granulare Temperaturkontrollsysteme

    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.

  • Thermisch optimiertes Design

    Thermisch optimiertes Design

    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.

  • Wasseraufbereitung


    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.
