How Wal-Mart is saving millions with clean tech

The Cleantech Forum that took place in Toronto this week had an interesting guest--Rand Waddoups, senior director of corporate strategy and sustainability at Wal-Mart, who regaled the audience with a pretty interesting array of facts and figures on the retailer's green push, according to Cleantech's news site.

Wal-Mart started to revamp its practices and become more green two years ago. The campaign revolves around good public relations, but also cutting costs. When you managed millions of square feet of retail space, small changes add up.

Some of the results:

The company is saving $1 million a year on … Read more

WiserEarth tracks the work of nonprofits around the world

WiserEarth, which launched in May, is an open-source database of more than 107,000 do-good organizations, with 5,400 users around the world.

The site incorporates Google Maps, wikis, and discussion groups, as well as listings of events, resources, and jobs. Users can create and maintain profile pages, and chat with members of other groups. Areas of focus range from agriculture to health to media to work, and popular forum discussions involve poverty, gender, and "planetary development." More calendars and regionally focused content hubs are being created.

Participants in the Bioneers sustainability conference this weekend were using WiserEarth … Read more

Interactive game illustrates your family's ecological footprint

Is your family burned out on Webkinz and Club Penguin? Are you ready for a new online "game" with a purpose?

The public radio producer American Public Media has launched an interactive game called Consumer Consequences that allows users to model their own ecological footprints. The game prompts users to describe their lifestyles in terms of house size, car travel, energy use, food and shopping consumption, and the mathematical model behind the game translates the information into an easy-to-understand visual summary.

The bottom-line result tells you how many "Earths" of natural resources it would take to sustain all 6.6 billion humans...if everyone lived like you.… Read more

True Green Confessions shares your planet-wasting ways

Ever fling fast-food wrappers from the window of your speeding Prius? True Green Confessions invites you to tell the tale. Unlike so many other green social networking websites that encourage you to practice bicycling, recycling and other planet-friendly habits, here you can share the shame of not doing enough or not caring enough about your fat carbon footprint.

There are many confessions about driving, like taking the SUV to the organic grocery store, as well as rants against "self-righteous" vegans. Other posts are a bit more twisted. One mother-to-be wrote: "I dont (sic) think I am contributing … Read more

When it comes to skyscrapers, is taller greener or smaller better?

I heard an interesting debate the other day on the topic of cities and skyscrapers. In a nutshell, when it comes to cities and buildings, is taller greener or is smaller better? In other words, should environmentally minded people like or dislike skyscrapers?

The Taller Greeners: Building up, rather than out, combats urban sprawl, means more concentration of people, means better for mass transit which equals fewer cars and lower emissions. Building bigger means more opportunity to use technologies like distributed generation, advanced energy efficiency, lighting and monitoring, which typically are more economic in larger projects.

The Smaller … Read more

MakeMeSustainable shows how green you can get

MakeMeSustainable is a new green social networking site. Although entering a crowded field, the service wisely translates how greening your everyday habits saves money. It tallies dollar signs, trees, and carbon emissions to track changes in your usage of electricity, heating, transportation, and travel over many months. I like that it takes you directly to sites where you can achieve a goal instantly, such as by buying CFL bulbs or carbon credits, or downloading a power-saving app for your PC. And you can form and join groups based around your interests.

MakeMeSustainable builds a personal profile based upon your quick … Read more

Prof says global warming is dangerous to your freedom

Nobody's going to like this one. Liberals will feel attacked. Libertarians will nod glumly. Conservatives will feel they're being blamed for something that hasn't happened. And those who intend to ignore climate change will continue to accuse others of a conspiracy.

Peter Wells, a researcher in Cardiff, England, has published an article warning that climate change could lead to a global, militaristic totalitarian state. Here's where you can find the article, but it will cost money to see it all. So, a brief summary: Climate change will create severe challenges to numerous nations. It may prove … Read more

Develop sustainably with Electrocity

Like a mini-version of SimCity, the Flash-based Web game Electrocity lets you develop your own metropolis from the ground up. Rather than existing solely as a entertaining Web diversion, however, Electrocity has a hidden agenda.

The sponsor of the game, Genesis Energy, is an energy provider and retailer in New Zealand. Electrocity was developed to increase public awareness about energy usage, its cost, and its effect on the environment.

Electrocity is a fairly simple, turn-based strategy game. You get 150 turns to create your masterpiece, but the challenge is to allocate resources wisely as you build. One-hundred and fifty turns … Read more

Solar-powered monitors not so bright?

File this in the "not there yet" folder. A bunch of blogs have covered a new, solar-powered system for NEC monitors, yet none show how it looks. My mind's eye pictured a tidy, laptop-size solar panel. But when I received this photo from NEC, I couldn't stifle a chuckle. Who wants to claw their way to a corporate window seat only to have mammoth solar panels block the view? Oh, and try not to kick that battery pack.

The equipment is designed for big businesses that aim to cut costs with clean, off-the-grid energy sources, but … Read more
