This includes activities with lower data traffic such as using ride-hailing apps and sending emails, to heavier ones like video streaming and big data processing.
Data and internet have made people’s lives easier but we often dismiss their environmental cost. To store and manage digital information, data centres use high volumes of energy and water to control temperatures.
Humans’ increasing dependence on data has caused a growing demand for data centres.
Indonesia currently houses 94 data centres with leading names including Alibaba Cloud, Google Cloud and state-owned-enterprise PT Telkom Indonesia. They have a combined capacity of 727.1 megawatts.
As an illustration, a small one megawatt data centre requires electricity to power 1,000 houses and consumes around 26 million litres of water per year. The number is expected to rise by about 20% each year due to the country’s growing digital activity.
The Indonesian government plans on constructing four National Data Centres by 2026 – each boasting a capacity of up to 40 megawatts.
Additionally, demand for data centres may shift to Indonesia from Singapore – the region’s digital powerhouse – which is currently limiting further growth of data centres due to environmental sustainability concerns.
Indonesia’s capital Jakarta is now one of the fastest-growing data centre hubs in the Asia Pacific, second only to Melbourne in Australia. But it’s important for these data centres to adopt sustainable practices to reduce their environmental impact.
So, how can Indonesia create a digital regime that is more environmentally sustainable?
Make them transparent and efficient
To control and minimise the environmental cost of growing data centres, the Indonesian government and industry players need to create plans for more sustainable methods of operation and reporting.
Currently, the government only imposes a mandatory reporting program on energy consumption for large energy consumers of about 70 gigawatt hours per year.
However, there are no data centres that meet this threshold. A hyperscale data centre consumes around 20-50 megawatt hours annually, far below the 70 gigawatt hours threshold. So reports on actual energy consumption from individual data centres have been unknown.
To ensure transparency, data centre operators – regardless of how much energy they consume – should collaborate to systematically report energy consumption. The public must also have access to the sector’s annual energy usage for greater accountability.
On top of this, the government should require the electricity usage of data centres to be efficient. In Singapore, for instance, data centres are required to have a ‘power usage effectiveness’ of 1.3 (the closer they are to 1, the more efficient a centre is).
The rule pushes operators to design and operate their data centres in the most energy-efficient way possible. This includes the usage of modern energy-efficient machines, which will significantly cut energy consumption and save costs in the long run.
The government should also encourage data centre operators to adopt more environmentally-sustainable energy sources.
Currently, several data centres in Indonesia have received Renewable Energy Certificates to prove their commitment to using renewable energy to power up their facilities from Indonesia’s state-owned electricity company, PLN.
In the future, the government could encourage more companies to adopt a similar approach, for example by giving tax incentives for industry players using renewable energy.
In Europe, a group of data centre operators, including the Amazon Web Services (AWS) and Google Cloud, have committed to buy enough renewable energy to match 75% of their total energy consumption by 2025 and 100% by 2030.
Behavioural adjustment in digital space is needed
Making sure data centres run as efficiently as possible is still only half of the battle however because emissions from data centres are not the only concern. There are also negative environmental impacts from the advanced use of data, many of which are difficult to measure.
For instance, there are environmental costs from increased consumerism due to the ability of big data and algorithms to flood users with the “right” advertisements and to keep users engaged in social media and e-commerce platforms.
Efficient data centres may become susceptible to the “Jevons Paradox”, where their optimised operations could encourage increased growth and resource consumption in the long term.
At the end of the day, technological innovations and efficiency alone cannot achieve sustainability – it has to be accompanied by a continuous behavioural adjustment in the digital space. Educating Indonesian users on the tangible impacts of their digital activities is an essential step.
