We live in an era where compute capability is ubiquitous, whether it be on a smart phone or mobile computer, and where “the cloud” can be accessed from anywhere.

In parallel, the ever-improving energy and carbon-efficiency of computers creates new opportunities to trade off atoms for bits, also known as de-materialization, and to substitute carbon-intensive activities, such as transportation, with tele-presence.

Here in Intel’s Eco-Technology group, we’re trying to learn precisely where these trade-offs exist, and under what conditions society can achieve net-positive outcomes, by harnessing technology in more environmentally beneficial ways. To that end, together with Microsoft’s sustainability group, we asked Dr. Jonathan Koomey, visiting professor at Yale’s School of Forestry and Environmental Studies and an expert in energy conservation technology, economics, policy and global climate change, to undertake a study of the environmental tradeoffs, between purchasing music in the traditional fashion (on CD from an online or brick and mortar store), versus purchasing and downloading the digital files.

The first food security assessment ever carried out by a UK government has been published, and it says that the country needs to change the way food is produced and the way it is processed, to maintain a healthy and affordable food ‘base’ in the future.

For as often as we do eat, it seems as if most of us don’t think too much about what we’re putting into our bodies. With food production so far removed from our every day lives, it’s easy to ignore where our food comes from and what it’s impact may be. But what we put on our plates has a larger footprint than what we drive. According to the Food and Agriculture Organization of the United Nations,

“Livestock production is one of the major causes of the world’s most pressing environmental problems, including global warming, land degradation, air and water pollution, and loss of biodiversity. Using a methodology that considers the entire commodity chain, it estimates that livestock are responsible for 18 percent of greenhouse gas emissions, a bigger share than that of transport.”

The things we choose to eat can obviously have an enormous impact on the planet and everything on it, including ourselves. Naturally then, our diet choices can say a lot about our ethics and beliefs. They can even be a political statement and a form of activism. I think that every choice we make has the potential to change the world, and certainly what I choose to eat has an impact.

Lettuce and biodiesel too, that’s the plan of Glen Kertz, CEO of Valcent Products of El Paso, TX. Kertz, who has worked in the greenhouse business for nearly two decades, believes the time has come to localize and simplify food production, and he says his Vertigro system will do just that. I spoke with Glen while he was attending an Orchid growers convention in Miami FL. We talked about his High Density [...]

Today let’s talk about the merits of turnips, rutabagas, and kohlrabi. Not to mention bok choy and burdock root. Hello? Anyone out there? Please don’t panic and run away at the mention of vegetables that don’t fall into the standard pre-cut, ready for stir-fry frozen bag you see at the supermarket.

As environmental stewards, we’re used to taking the path less traveled to make a difference: pulling out the

Americans eat more than a ton of corn every year. Literally, a ton. Right now, you’re thinking, "There’s no way. No one eats that much corn, even in August." Well, that ton is not really corn in its unsullied, fresh-from-the-field, bought-at-a roadside-stand form. Nor is it in its canned-creamed-or-not form. Most of the corn we eat is in the form of processed additives and sweetners. Green Options’

We may live on an organic farm powered by renewable energy, but our son, Liam, requested standard kiddie supper fare for his recent sixth birthday party: macaroni and cheese. No problem, said his parents, and we made a few casserole dishes of the mac and cheese recipe you see below. Both kids and parents ate heartily and were satisfied — and no cheese sauce came in a powdered form out

Leeks fall into that same food group as rhubarb: nutrition and flavor powerhouses that, sadly, wilt away in the produce aisle because we no longer know how to use them in cooking. But, unlike rhubarb, leeks don’t need gobs of sugar or other ingredients to make them palatable. Historically, leeks appeared on Fall harvest tables throughout Western Civilization, from Roman to European times. The Welsh placed leeks on a revered pedestal

Sustainability is making its way into mainstream periodicals. It seems like almost every magazine in the past year has featured a "green" issue, some credible, some not. My friend just gave me the green issue of a magazine targeted at the marketing industry. So it’s no surprise that Edutopia, an education magazine for teachers and administrators published by the George Lucas Educational Foundation, used sustainability as a theme for their

Chocolate, chocolate, chocolate. The word is music to my ears, while the thing itself – when it is a bittersweet pearl of cocoa, or a spicy hazelnut praline, or again the warm melting heart of a rich gateau – why, no words can describe it! No wonder the famed Azetec Emperor Montezuma drank 50 cups of chocolate a day. No wonder the Swedish botanist Carl Linnaeus chose the name "Theobroma cacao" or "food of
