Online Home Water-Energy-Climate Calculator

Are you wondering how much water your household uses? The Pacific Institute offers a great free tool to estimate your homes energy use. I went through the survey and the website gave output many pages of statistics, figures and tables. It appears that the pacific institute's ultimate goal is to help us realize the embedded energy that we move through when we use water. Embedded energy is the total energy used by a utility to collect, treat, and distribute water to the customer and to treat wastewater.


The calculations have many assumptions built in. I was battling it's assumptions for leaks, but then I read the fine print.  The website operates on the assumption from an AWWARF study finding that states nearly all houses have leaks. The study, Residential end uses of water is linked here.

Conspiracy theory on climate change: DEBUNKED

This is a great work which is necessary to depoliticize climate science.  

EPA Rejects Claims of Flawed Climate Science

EPA denied 10 petitions challenging its 2009 determination that climate change is real, is occurring due to emissions of greenhouse gases from human activities, and threatens human health and the environment.  The petitions to reconsider EPA's Endangerment Finding claim that climate science cannot be trusted, and assert a conspiracy that invalidates the findings of the Intergovernmental Panel on Climate Change (IPCC), the U.S. National Academy of Sciences, and the U.S. Global Change Research Program.  After months of serious consideration of the petitions and of the state of climate change science, EPA finds no evidence to support these claims. In contrast, EPA's review shows that climate science is credible, compelling, and growing stronger.  Additional information is available at:
