Water & Energy: an intensifying interdependence

NextGen spoke to a number of thought leaders and innovators at Water Innovation Europe 2019 about the circular economy and intricacies of the water-energy nexus. A keynote speaker was Molly A. Walton: Energy Analyst at the International Energy Agency (IEA). We caught up with her for a quick interview after a data packed presentation and here’s what she had to say… NextGen: When we talk about water and energy what do you think the big trends and challenges for the sector? Molly Walton: First, it’s helpful to put the water-energy nexus into context before looking at the challenges. Today, the energy sector accounts for around 10 percent of total global water withdraws and 3 percent of total global water consumption. If you look at the other side, the water sector uses about as much energy today as Australia. Given that energy and water demand are set to increase in the future, when we look forward we see that the linkages [between energy and water] are also set to intensify. According to analysis by the International Energy Agency (IEA), the energy sector’s water withdrawals rise by about 2 percent and its consumption goes up by 60 percent by 2040 – this is a quite important point...
