Energy and Water Team Up at This Year's World Water Week

If you're going to take a week to gather most of the world's brightest minds working on water issues, you couldn’t pick a better place than Stockholm, Sweden. Every year since 1991 the city – 30 percent of which is made up of beautiful, winding waterways – plays host to World Water Week, organized by the Stockholm International Water Institute.

This year's theme is Energy and Water, which if you read this blog you know makes us very happy. For years we've written about how water and energy are closely linked: It takes a lot of water to create energy and a lot of energy to move, heat and treat water.  It doesn't matter if you’re managing a power plant and becoming concerned about recent droughts, or you're a homeowner wincing as you pay your high water heating bill, water and energy connections affect us all. Below we’ve pulled together a series of recent posts that help to illustrate just a few examples of the water and energy nexus…although we sadly can't offer a stroll along the Norrstrom.

Energy-Water Nexus

The Water Footprint of Energy
You may not realize it, but when you use energy, you're also using water indirectly, sometimes a lot of it! Read on to find out about the water it takes to produce electricity, to extract and refine transportation fuels and to make biofuels, especially corn ethanol.

Water Saving Tips: The Water in Your Energy
When you save energy you also save water. These energy-saving tips will also lower your water footprint.

Fracking

Really? Shale Gas Fracking Uses a Lot of Water? Really!
Why do oil and gas companies celebrate their monumental frack jobs but then downplay them at the same time? In a word: water (and a lot of it). Check out our infographic on hydraulic fracturing's problematic thirst.

California Halts Injection of Fracking Waste, Warning it May Be Contaminating Aquifers
In this ProPublica crosspost, California officials have ordered an emergency shut-down of 11 oil and gas waste injection sites and a review more than 100 others in the state's drought-wracked Central Valley. Fears exist that gas companies have been pumping fracking fluids and other toxic waste into drinking water aquifers.

Power Plants Kill Fish

10 Things to Know about Power Plant Water Use, 10 Reasons to Care
Many of the nation's older power plants have a huge thirst for water. Here are 10 things you should know about power plants and their water use and 10 reasons why you should care.

Power Plants Kill Fish – Animation
Many older thermoelectric power plants require tremendous amounts of water for cooling. This animation takes you through the process and illustrates why there are such devastating consequences for fish and other aquatic life.

So Where Does All That Mercury in Fish Come From?
If you look at a seafood guide you're bound to come across the ominous warning: "High in Mercury." But what does that mean? And how is mercury winding up in the fish on your plate?

Biofuels

The Rush To Corn-Based Ethanol: Not All Biofuels are Created Equal
Global demand for fossil fuels is growing and gas prices are volatile. Along with this, concerns about climate change from fossil fuel emissions make alternative fuel sources look increasingly attractive. However, corn-based ethanol, the most prominent biofuel in the US, is not the solution to any of these problems.
