Green Data Centers in 2018: How Has Industry Opinion Shifted?

As we release our 2017 Sustainability Report, we wanted to see how the industry opinion on green data centers may have shifted over the years.

Back in late 2014/early 2015, Green House Data put out a survey for data center workers asking for their opinions on green data centers. At that time, the results showed that most industry insiders thought energy efficiency and sustainability was most important for the bottom line, rather than for Corporate Social Responsibility. It did not appear that very many sought out green service providers specifically.

We recently sent out a follow up survey. Our sample size increased from 166 to 789. 10% of the respondents did not have input into their IT and infrastructure decision making, leaving 710 IT decision makers answering our questions.

Nearly ¼ of all respondents worked in the IT industry, with another 20% coming from Healthcare, and Finance wrapping up the top three industries with 10%.

The results were surprising, to say the least.

In-House Efforts Towards Green Computing

This was perhaps the largest backslide compared to 2015. Individual organizations were less likely overall to make green choices for their own infrastructure EXCEPT when choosing service providers.

Some 36% of survey respondents chose green service providers, an 8% increase over 2015. 60% recycled electronics, another increase of 4% over 2015. Companies were only 1% more likely to use free cooling. And while slightly more people reported using direct on-site renewable energy generation, there were also less people purchasing Renewable Energy Credits.

Perhaps what was most surprising about this question is an 8% reduction in the number of offices that recycle. Come on, guys!

In the meantime, data center goals in the next three years remain much the same. IT professionals report that by 2021:

• 15% plan to build, purchase, or rent a data center
• 26% plan to expand or migrate to public cloud
• 37% plan to expand or migrate to hybrid cloud
• 26% plan to consolidate data centers
• 30% plan to colocate new or additional equipment

As stated above, 36% of survey respondents look for green-leaning service providers. That increase held up to further scrutiny, as green factors became signifacantly more likely to be considered “Very Important” when looking for a service provider.

• Data center PUE was 26% more likely to be listed as Very Important
• Overall Environmental Impact was 21% more likely to be listed as Very Important and 4% more likely to be a Primary Focus
• Renewable Energy Use was 13% more likely to be listed as Very Important
• Green Technology Investment was 10% more likely to be Very Important and 5% more likely to be a Primary Focus

In 2015, a full 25% of IT professionals said data center PUE was “Not At All Important,” but today only 12% agree. More people found the Total Energy Consumption to be Very Important, too.

This marks a demonstrable shift in attitude, with green factors across the board shifting into a more important decision maker when evaluating a service provider.

How Is the Cloud Affecting Green IT?

One of our most interesting questions had the most dramatic swing of any statistic in the survey. When asked if the move to cloud computing is improving the environmental impact of enterprise computing overall, 86% of respondents said yes.

Compare that to 2015, when only 67% said yes, and you’ll see that more of the industry now believes the cloud is making enterprise IT more environmentally friendly. Today, only 14% claimed that the cloud was not any greener than traditional data centers.

The reasons given now overwhelmingly backed the concept of efficiencies at scale, with a smaller overall footprint for the same or greater amount of compute power. The few holdouts stated that in the end, you’re still facing an ever-increasing amount of demand for computing power, so the ultimate result is in fact a higher footprint.
