SIX KEY STEPS

FOR SUSTAINABLE NETWORKING INFRASTRUCTURE

As every corner of the globe is encouraged to increase their use of renewables , Mattias Fridström , Vice
President and Chief Evangelist , Arelion , provides six considerations for network operators to help fast-track a greener future and ease the appetite of hungry data centres . ccording to the United Nations , fossil fuels ,

A including coal , oil and gas , currently account for over 75 % of global greenhouse gas emissions and nearly 90 % of all carbon dioxide emissions . In addition , it observes that fossil fuels still account for more than 80 % of global energy production , with only about 29 % of electricity currently coming from renewable sources .

The UN states that the science is clear . To avoid the worst impacts of climate change , emissions need to be reduced by almost half by 2030 and reach net zero by 2050 . To achieve this , we need to end our reliance on fossil fuels and invest in alternative sources of energy that are clean , accessible , affordable , sustainable and reliable .
As if this challenge were not enough , Russia ' s invasion of Ukraine has added an energy crisis into the mix . As the Institute of Economic Affairs ( IEA ) highlights in its World Energy Outlook 2022 , ‘ Today ’ s energy shock is a reminder of the fragility and unsustainability of our current energy system . A key question for policy makers is whether the crisis will be a setback for clean energy transitions or will catalyse faster action .’
The IEA ' s analysis – at least in the longer term – is optimistic . It says that government responses to the crisis in major markets are ‘ fast-tracking the emergence of a clean energy economy ’.
It calculates that policies around the world will help propel annual clean energy investment to more than US $ 2 trillion by 2030 , a rise on current spending of more than 50 %. It predicts that as markets rebalance , renewables , supported by nuclear power , will see sustained gains , with the recent upside for coal from today ’ s crisis being short-lived .
The IEA concludes : ‘ The world is in a critical decade for delivering a more secure , sustainable and affordable energy
