What do you think of when you hear Deloitte? You might think of a professional services firm or Big Four auditor. Today, the company has also put a big green stake in the ground, both looking internally to green its operations and as an offering in its consulting practice. Two aspects of this work are worth noting: Deloitte’s internal green team, working to engage employees in sustainability, and its Green Sync™ tool. I had the chance to have an e-mail exchange with Thomas Dekar, vice chairman of Deloitte LLP, regional managing principal of the North Central Region and corporate responsibility officer for the Deloitte U.S. Firms. He shed some light on the origins of Deloitte’s programs and offerings. Read on to learn about Deloitte’s best green business practices for engaging employees in sustainability.

BoingBoing.net is reporting today on a tabletop "hydrogen power station" that produces hydrogen from water using a standard power outlet and costs around $200. While this may sound wonderful on the surface, it merely illustrates how the notion of a “hydrogen economy”� is really a myth. Let's get one thing perfectly clear: hydrogen is not a energy resource. Hydrogen does not exist naturally in any sufficient quantities to make it a viable energy source, at least on this planet. To get hydrogen in any useful quantities, it must be extracted from natural gas, water or biomass, and all of these result in a net loss of energy. It is more efficient to use these fuels in their original forms.
