Background info

Hidden energy

Each day we charge our devices so we can use apps and create social media posts, often without considering that these apps, posts, and data storage use energy to take a physical journey around the world. In addition, data is kept in mega data storage centres where it is saved, processed, and the data and apps disseminated. Often the energy source used in this process is fossil fuels. 

Data centres

Hyperscale data centres are being built all around the world and contain IT products and tens of thousands of servers and hardware. This is in part a response to a rapid growth in cloud computing, SaaS (software as a service where software is licensed on a subscription basis and centrally hosted), e-commerce, gaming and video services. Many large tech companies, owning and operating these hyperscale data centres, are responding to the climate crisis with commitments to use green energy and sustainable business practices. 

Smart sustainability

With the increase in information flow and connectivity in our world, we need to be discerning about how to interpret the information. Greenwashing is when a business makes incorrect or misleading claims about its sustainable initiatives. But many companies are honestly striving to be sustainable by switching to renewable energy sources and adopting other sustainable practices. The challenge is to differentiate between the two. A sustainable company will share proof to support its sustainability claims and targets and will be transparent and honest about its progress in reaching these targets. 


  • Assess students’ understanding of the energy used by large data centres and the need for tech companies to commit to a low carbon future. 
  • Assess students’ critical thinking and reasoning as they present their arguments in their opinion piece.
  • Assess students’ ability to apply an analytical lens to company claims of sustainability.
