When you think of March, you think of
St. Patrick's Day. And what color immediately comes to mind? Green. But today,
the color green has taken on a brand new significance as the symbol of the
booming green energy movement. That has become a vital component of Europe's
economy-including the nation where St. Patrick's Day originated. As the
preeminent data center provider in Europe, Interxion (NYSE: INXN) is leading
the charge in both efficient energy practices and the use of renewable energy, showing
that being green is a crucial way to win customers in Europe.
Demonstrating green practices can be
a notable business differentiator for service providers looking to sell
services to the European market. Europeans care strongly about sustainability:
slightly more than eight
in ten E.U. citizens felt that environmental impact was an
important element when deciding which products to buy. One example of this
practice is Taxi
Stockholm - who has an initiative to be completely free by 2025,
an initiative that extends to their data center and IT service provider Devinix
as well. So, for U.S. companies that are trying to take advantage of the
European market, colocating in data centers committed to both using green
technology and innovating new efficiency measures is a way to distinguish
themselves from their competitors.
At Interxion, energy efficiency is a
company-wide policy, with energy-saving measures built right into its data
centers. For more than 20 years Interxion has
pioneered energy-saving designs and harnessed everything from arctic winds to
underground aquifers to the Baltic Sea to reduce its energy use and thus reduce
its carbon footprint.
For data center providers, much of
the daily operations involve ensuring the equipment is kept cool to ensure
customers' mission critical applications are kept running 24/7/365. Interxion
is innovating and implementing advanced energy-efficient cooling technologies:
for example, free-cooling reduces the use of electricity, which is still
predominantly produced from conventional fuels. These energy efficiency
measures are examples of Interxion making a positive environmental contribution
for its industry and its customers.
In
addition to energy efficiency, Interxion pioneered the use of 100% sustainable
energy sources, including water, solar, and wind to power its data centers
across Europe. And between 2017 and 2019, Interxion chose to redeem all of its
data centers' electricity usage in the form of renewable energy produced in
Europe, either via supplier's green tariffs or Guarantees of Origin.
Interxion has played a critical role
in the sustainability efforts of its host cities. A notable example is
Stockholm: in the 1970s, Stockholm took energy efficiency to a new level by
building infrastructure that reused excess heat to warm households in the city.
Interxion is a key partner in this groundbreaking initiative: together with Stockholm Exergi, Interxion is transferring
the excess heat energy into residential heating. In 2018, Germany's two biggest TV networks traveled
to Interxion's Stockholm facility to film documentaries about the city's
power-saving technology with hopes that other countries or cities will soon
adopt similar practices.
In Denmark, Interxion has
developed groundwater cooling as an energy-saving measure. Previously, cooling
in the summer months had been based on traditional refrigeration machines that
used a lot of power. But Interxion worked with the city of Ballerup to develop
a groundwater-based cooling system that can replace the traditional
refrigerants with geo-energy. The result is a system that, summer and winter,
can always provide sufficient cooling while significantly reducing energy
consumption.
Denmark and the whole Nordic region
have evolved into Europe's leaders in energy efficiency. Not only are
Interxion's Nordic facilities designed specifically with byproducts like excess
heat in mind, they are among the only data center providers covering the whole
of Europe with 100% sustainable energy. Hyperscalers like Apple and Google have
applauded the Nordics for their energy efficient data centers.
The great supply of power
from sustainable sources like hydro- and wind power combined with the cold
climate makes the Nordics an ideal place for building sustainable data centers.
Due to this and a fast-growing market in Northern Europe, Interxion is seeing
an increased number of hyperscale data center projects emerging in both Denmark
and Sweden.
Green-laden Ireland is another region
in Europe where energy efficiency is thriving. The Emerald Isle's temperate
climate makes it perfectly suited for free-air cooling, which uses approximately
40% less electricity than typical cooling methods. In addition to energy
efficiency, Ireland is a leader in sustainable energy: 26% of the energy that Ireland produced in 2016 came
from sustainable sources. It also possesses the third-highest wind penetration
in the world. In fact, Ireland has set a target of having 40% of all its
energy generated from renewable sources by 2020. It's quite ambitious, but
completely reachable.
In addition to sustainable energy,
Interxion's Ireland data centers are making major contributions in energy
efficiency. Interxion has pioneered new approaches to data center design and
management, including improvements around power usage effectiveness and the
industry's first-ever modular approach to data center design. Interxion even
designed its newest Ireland data center DUB3 with a specific focus on
energy-saving modular architecture, incorporating cooling and maximum efficiency
components.
Interxion's efficient and sustainable facilities
have changed the conversation around data centers. Once feared as a source of
pollution, data centers are now embraced for their energy contributions to
surrounding communities. Enterprises that wish to boost their business in
energy-conscious Europe have also embraced data centers equipped with green
technology. With such enormous benefits to the data center industry,
environment, and local communities, it is easy to imagine Interxion's green
energy initiative is a win for all.
