Irrigation Scheduling for Agricultural Crops: It’s Not Just a Flip of a Switch!

For this second post in the “Sustainable Agriculture on Cleantech Blog” series, I decided to invite Dave Doll, UC Cooperative Extension Farm Advisor, and fellow blogger at Almond Doctor Blog, to share his expert knowledge about irrigation management for agricultural crops. Agricultural use of water within California use has been a media magnet these days. […]

Robert Metcalfe Is Wrong, Clean Technology Alone Will Not Work

by Marguerite Manteau-Rao I got a sneak preview of Scientific American’s Earth 3.0 special issue on ‘Solutions for Sustainable Progress’. Mostly great stuff, with the exception of one article, that prompted me to write this rebuttal. In ‘Learning from the Internet’, Robert M. Metcalfe, venture capitalist and Internet pioneer, expands on the dangerous idea that, […]

Huge Opportunities to Do Good and Do Well with Green IT

by Marguerite Manteau-Rao McKinsey is on a roll, with yet another eye opening report, this time on ‘How IT Can Cut Carbon Emissions’. The study highlights the key role IT can play in maximizing energy efficiency across sectors, more than compensating for carbon emissions from IT equipment manufacturing and operation. Yet another example of the […]

Climate Change a Game Changing Factor for Corporate Valuations

by Marguerite Manteau-Rao Smart industry leaders better listen to McKinsey’s just released study on the likely impact of climate change mitigation scenarios on corporate valuations.

Getting Content Into Sustainability Wikis

by Marguerite Manteau-Rao (This post originally appeared on La Marguerite blog) Sustainability wikis such as Wikia Green or Appropedia have an important role to play, in the gathering of solutions for a sustainable future.

8 Lessons From Twitter Energy Monitoring

by Marguerite Manteau-Rao Two weeks and 77 tweets later, the Twitter “green_watch” project has come to an end. Lots of insights, problems raised, and beginning of answers. The goal was to use Twitter as a real time, online reporting tool for my personal energy consumption, round the clock. Lessons learned from the project: #1. The […]

Energy Monitoring With Twitter

by Marguerite Manteau-Rao This week, I started a new experiment, this time using Twitter to monitor my energy consumption 24/7. A Web 2.0 version of my earlier Daily Footprint Project, when I kept a diary of all my carbon footprinting activities for 30 days. The project is called “green_watch” and you can follow it on […]

Are Clean Tech and Sustainability Types Afraid of Web 2.0?

by Marguerite Manteau-Rao Social media and sustainability may align in at least ten ways, according to Max Gladwell, but they certainly do not intersect very much in actuality. Proof is this quick search I conducted on Twitter, of last 24 hours of business conversations on “sustainability”, “clean tech” and “green”. Here are the results. I […]

More on what’s wrong with biodiversity?

This question from Tom Friedman has been on my mind. After all, I […]

Green, a Dead End For Social Networks?

by Marguerite Manteau-Rao A while ago, I wrote about ‘Why Green Social Networks Don’t Work‘: ‘Green social networks are popping all over the place. Frankly, I have stopped keeping track. They want us to become engaged, and to change our behaviors, fast. They claim to have all kind of tools to help us accomplish the […]

Green Supply Chain Management, It’s Good For the Environment, It’s Good For the Bottom Line

by Marguerite Manteau-Rao While the majority of global executives consider carbon reduction an important aspect of purchasing and supply chain management, only a minority follow through: That’s too bad, according to the McKinsey study. Not only are these companies not helping fight climate change as much as they could, they are also missing out on […]
