The Zen of Green Software: Finding Balance in the Sustainable Growth Journey

As businesses continue to evolve their operations to meet consumer demands and remain profitable, reliance on the IT sector will only grow. Today, it’s estimated that this sector contributes around 3% of global CO2 emissions, on par with the aviation industry. Expansion of a customer base and a drive for increased revenue is on an upward trajectory. This often translates into increased demand for energy needed to power data centers roughly doubling every four years, and even in a best-case scenario, the ICT industry is likely to account for 8% of total electricity demand by 2030–a 15-fold increase from 2010. Achieving a balance between growth and efficiency can be a formidable task. Software engineers can play a critical role at the nexus of both, enacting small changes to daily tech operations and software development which will add up to a big impact. This is where Green Software as practice and mindset intersects with business strategy to achieve measurable results across an organization.

In this talk, we’ll discuss open source software tools and methodologies for balancing carbon with growth across your IT organization. You’ll walk away with actionable approaches to greening your IT organization in your daily work.
