Ongoing data centre upgrade projects contributed to a decrease of 5% in energy consumption at our data centres in 2014 despite increasing online delivery of our products and services. Total energy consumption decreased by 7% against 2013, due in part to improved energy efficiency at our offices. In the year, 65% of the electricity assigned to our data centres was classed as renewable energy.
We realise the challenge in reducing absolute energy usage while continuing to grow our business and therefore have set targets to increase renewable energy usage. In 2014, we purchased 46% of our electricity from renewable energy and renewable energy certificates compared with 38% in 2013. We aim to increase this to 50% in 2015, and 100% in 2020. As we are predominantly in leased locations with few opportunities for onsite generation, we rely on green tariffs and RECs, while investigating options for offsite generation. In 2014, the Group was listed as a Leader by the US Environmental Protection Agency’s Green Power Partnership. Read more in the 2014 Corporate Responsibility Report
