GreenTalk Radio host Sean Daily talks to Stephanie Thornton of the EPA about their WaterSense program. Much like the EnergyStar program, WaterSense seeks to help Americans to save water and protect the environment by creating product efficiency standards that manufacturers must meet in [...]

BrightTALK is sponsoring an Earth Week webcast summit, featuring free presentations on water management, green building, green IT, and green marketing.

Many green buildings address water efficiency as second to energy efficiency. But, as this article shows, they are more closely tied together than we may think.

Is your home healthy?  Residents in Calgary, Alberta, are getting answers to that question from the Healthy Homes Calgary program offered by Clean Calgary Association.

The new residential service provides free home visits to Calgarians who are interested in “creating a healthy living environment, while reducing the home’s eco-footprint.”  A staff member or trained volunteer shares tools and information city residents need to improve indoor air quality, energy and water efficiency, waste reduction and more.

2008 - what a year! As we get ready to draw the curtains on one of the most unsettling economic years in history, we the writers of the Inspired Economist are still wondering… was this year one that has left our battered economy begging for inspiration? Or have the sustainable events of 2008 spearheaded the initiation of what we believe is truly an Inspired Economy?

2008 was about the $700 billion bailout. Foreclosures. The plummeting stock market. As the year came [...]

The Environmental Protection Agency’s WaterSense program is the EPA’s water efficiency equivalent to its wildly successful and well-known Energy Star program. Watersense’s mission is to protect the future of the U.S. water supply by promoting and enhancing the market for water-efficient products and services.

WaterSense has jumped onto the internet “widget” bandwagon, and recently released a widget that provides a jump to the WaterSense website, which includes tips [...]

Showering is one of the major uses of domestic water. Showering is responsible for roughly 18% of indoor water use. But with a new kind of shower system invented in Australia, showering could, according to the manufacturer, use 4 times less water and save up to 87% of the energy used in typical showering.

Australia has been suffering through a drought for the last several years. Since 2003, most of Australia has been experiencing the most severe drought conditions on record. And Australia is the driest populated continent, which further exacerbates water issues there. So it’s not surprising that a super-efficient shower would come from Australia.

According to the Quench Showers brochure, “If we focus on Australia’s water position we are at crisis point. Being aware of this is a start, but more importantly, we all need to understand the crisis and take immediate action if we are going to influence change. Without changing the way we consume and manage our water usage in our day-to-day activity, this crisis will become a widespread catastrophe!”

So how does the Quench shower save so much water and energy?

They’re not sexy, and the Department of Energy estimates 13% of your home energy consumption goes into a big tank of hot water. I’ve seen other estimates that go higher, and a larger or older tank will burn more energy. So your water heater may be one of the more boring appliances in your home, but it’s a leading load on your energy bill. Fortunately, there are easy ways to fix that.

First let’s talk about how to improve a water heater that you already have. For less than $20, you can hit your local DIY hub/ home improvement store and buy a water heater blanket with quick and easy assembly instructions. If Internet testimonials are true, it will probably take more time to drive to the store and buy one, than it will to install it. If your water heater already has a blanket, bravo! Just keep in mind that the big sticker on the front of your water heater has some important information. You might want to tape it to the blanket for easy reference. While you’re at it, you could also consider insulating some of your pipes or ducts (see first link in this paragraph) for even more savings.

As for the yawn-factor on water heater tanks, check out my favorite Myth Busters episode from the Discovery Channel. (Please don’t try at home, duh)

Reducing the amount of water you use is good for the environment, and good for your wallet. Better yet, you don’t have to sacrifice water pressure to do it. Check out the best water faucet aerators of 2008.

Water shortages are on the rise, from Mexico to the Andes, northern China to southern India, and Spain to Pakistan. Drought, soaring populations and population densities, changing diets, and increasing living standards are all factors. Is this an issue that technology can fix?

Judging by investors’ responses, the answer seems to be yes. FourWinds will invest up to $4.7 billion in water treatment and desalinization and companies that make meters, pumps, and pipes.

BlueWater Bio is a player in the wastewater and sludge treatment arena. Their claim to fame is a treatment technology called Hybrid Bacillus Activated Sludge (HYBACS). It uses proprietary bacteria that eats waste, saving on chemicals. The high quality treatment effluent has reuse potential for commercial or industrial applications, but I wouldn’t recommend drinking it.

Monsanto’s top 20 experts have been examining how climate science will affect the company, with drought being the leading problem to solve. New drought-resistant crops are being created.

“The most advanced of these is now a drought-tolerant corn product … commercializable within several years,” said Monsanto’s head of technology strategy and development David Fischhoff . “We expect this to be the first generation of an ongoing stream.”

Solar thermal technology provides space heating and hot water and is a frequently forgotten member of the solar family. These highly effective systems are popular in many parts of the globe, from China to Greece to Zimbabwe. They displace the use of the existing hot water heater and heating equipment, typically saving either natural gas or electricity.Solar thermal is a more mature technology than solar photovoltaic systems that produce electricity. It has been used for centuries for water heating. In fact, even Leonardo Da Vinci owned one.

When considering the installation of such a system, it is important to consider the following items.
