How much water should an email consume? Data centers and water use

 A mid-sized data center consumes around 300,000 gallons of water a day, or about as much as 1,000 U.S. households;

About 20% of data centers in the United States already rely on watersheds that are under moderate to high stress from drought and other factors;
Operating a data center often requires a tradeoff between water use and energy use;
And in a survey of 122 data centers in the United States, only 16% or 20 utilities reported plans for managing water-related risks.

As professionals working in the field, what can we do to solve this issue? One aspect is developing and using water models that can identify water risks at different scales - so that we can predict the risk to water supplies under a changing climate. A second is using machine learning to identify and optimize water use between all the stakeholders in the watershed - data centers, farmers, cities, other industries - so that biases and needs are brought out into the open and the key issues identified. A third, of course, is developing and implementing technologies that can help reduce water use (for example air cooling instead of water cooling), or increase water availability (desalination or remediation and reuse of non-potable water sources). However, all these come with tradeoffs - using air cooling increases energy use for example - which will need to be identified and articulated while making decisions. And that's where being able to use process models, statistics and machine learning effectively in these situations is so powerful!

Moonshots, Models, IoT and Machine Learning in Agriculture

  What do Google, Climate Corporation, early stage startups in farm robotics, and researchers trying to figure out how to feed the world sustainably have in common? They’re all grappling with one of the toughest challenges of working with natural systems - how do you work with data that is sparse, unevenly distributed and with systems that have so many connections and interactions with other systems?     Before the advent of cheap sensors that are connected to phones, easily accessible satellite data and drones that can fly over fields quickly and inexpensively -     scientists in companies and academia worked on developing plant and crop models that incorporated as many aspects of the farm and as much data as was available so that they could understand and predict what was likely to happen on the field. Understandably, the forecasts took some time to produce and as the models grew more complex, issues about how to estimate model parameters and the uncertainty a...

What’s the impact of your smartphone? Mapping the distribution and environmental impact of mines around the world

Image
How many different materials go into making your smartphone? According to the American Chemical Society, at least 64 different types of chemicals constitute your smartphone . Many of these materials, particularly the heavy earth metals, are extracted from the Earth through mining operations. Mining has been a part of human society for several thousand years now - from the shallow mines of earlier centuries to the more extractive ones created in the last hundred years. The challenge of mining and other extractive industries is that they are essential to many of our needs today - coal for energy, silicon for solar panels and heavy earths for electronics being among the well known ones. At the same time, they cause significant damage to local environments through the disturbance to the land caused by establishing the mine itself, to environmental impacts on water, land and ecosystems from mining operations.   So far, it’s been difficult to map the spatial extent and environmental impa...
