I recently learned about a project from Circle of Blue called ChokePoint: US, a four-month reporting project where journalists set out to better understand what is occurring in the places where rising energy demand collides with diminishing supplies of fresh water. Check out the website for featured stories, multimedia and infographics about hydropower, coal, oil, tar sands, fracking, and renewables.
Check out the interactive infographic titled: Energy Used in the Water Cycle that details the amount of electricity that is needed to transport, distribute and treat the water we use in our homes and businesses as well as the industrial and agricultural sectors. While electricity plays a role in many steps of this water cycle, most electricity use occurs with the end users – customers who heat water to bathe, cook, etc.
For those of you who take your students on tours of water treatment plants or waste water treatment plants, consider asking the plant operators to discuss the plant’s use of electricity to pump, move and treat water.
