Companies that opt to delay sustainable priorities over the next five years will find it impossible to catch up as sustainable business continues to become a new standard.

The above quote is from Gartner who says this in the analysis “Build and advance sustainability programs”. Although primarily directed at the logistics business, the analysis is based on key factors that are just as important for the IT-sector and it’s data centers.

  • Data centers throughout the world are now using approximately 3 % of the worlds available energy (about the same as Great Britain), and are responsible for 2 % of the worlds total carbon dioxide emissions.
  • This is now more than the aviation industry, and these numbers are expected to double every 4 years.
  • This - obviously - cannot continue.

According to Gartner (and trends we see emerging more and more) - you should not be satisfied with this. Regardless of which part of this supply chain you are a part of, if you want to keep your business/customers, you have to change towards green.

Consumers

There is a big push towards sustainability in the consumer market. Forbes did a survey about this and concluded: “Our survey revealed an overwhelming demand for brands to step up on sustainable lifestyles. If your brand isn’t helping your consumers improve their environmental and social footprint, then you’re in danger of disappointing 88% of them.”

This trend among consumers is coming to the IT-sector and it’s data centers as well. Should you, as a supplier in this market, follow your customers? Undoubtedly. But even better: Get there before them.

Suppliers

Some suppliers have already worked on this; Microsoft has a sustainability calculator that helps the customer see how much of what kind of energy goes into their server rig, either on-premises or in Azure. They also announced that they were 100% powered by renewable energy already in 2014, although by purchasing RECs (renewable energy credits).

Amazon (AWS) are building huge wind and solar farms to help them in their goal of achieving net zero carbon emissions by 2040.

Maybe the best idea so far is the dutch company Nerdalize who instead of putting their customers servers in data centers, put them in private households to heat radiators and water. (Unfortunately, they seem to have gone out of business since their crowdfunded startup in 2017).

There is a big challenge here: IT is rather dependent on electricity. Servers and data centers cannot just turn off the power at night to be environmentally and politically correct. There are however quite a few ways to be environmentally aware about this. Read the next instalment to learn more.

Lombok – avoid getting burned by the boilerplate

Executive summary

This blog describes briefly the most commonly used annotations of the code generation tool Lombok which shields the Java developer from having to generate or write so called ‘boilerplate code’. It begins with explaining that term and the problems it may cause, continues with a brief setup description of a Maven based Java project that incorporates Lombok and then display some useful annotations.

These annotations are grouped after function such as object creation, field access, some methods ... [continue reading]
