    #62 Thirsty datacenters in the heart of Silicon Valley with Masheika Allgood
    Aug 18 2025
    A month ago, Google released its 2024 sustainability report. Its overall water consumption increased by 28% in a year. Less publicized than the data center energy boom, water is also pivotal for the Tech industry and data is even scarcer. To better understand this secret but serious love affair between big tech and water, what better location to investigate than its birth place? Yes. THE silicon valley. And no one there is better qualified to explore the topic than Masheika Allgood who lives in Santa Clara and recently created a Data Center Water Consumption Calculator based on public data. Over their conversation, Gael Duez and her covered: - The astonishing amount of water used by data centers in California and why it could have been even worse - “Back to the loop” & the limits on the efficiency gain from new cooling technics - Air pollution & the trade-off of heat reuse in urban area - The unignorable noise pollution - How big tech lawyers have an edge on city council and community activism And much much more! ❤️ Subscribe, follow, like, ... stay connected the way you want to never miss an episode, twice a month, on Tuesday!

    #60 Why Tech companies should not deprioritize future readiness with Rainer Karcher
    Jun 24 2025
    “Climate activist in a suit”. This is how Rainer Karcher describes himself. It is an endless debate between people advocating for the system to change from the outside and those willing to change it from the inside. In this episode Gaël Duez welcomes a strong advocate of moving the corporate world into the right direction from within? Having spent 2 decades in companies such as Siemens or Allianz, Rainer Karsher knows the corporate world well, which he now advises on sustainability. In this Green IO episode, they analyse the current backlash against ESG in our corporate world and what can be done to keep big companies aligned with the Paris agreement, but also caring about biodiversity or human rights across their supply chain. Many topics were covered such as: Why ESB has nothing to with “saving the planet”, 3 tips to tackle the end of the month vs end-of-the world dilemma, Embracing a global perspective on ESG and why the current backlash is a western world only issue, Knowing the price we pay for AI and how to avoid rebound effect, the challenge with shadow AI and why training is pivotal, and yes they talked about whales also and many more things!
