The energy consumption of avatars


by

Virtual worlds (World of Warcraft, Second Life) and the avatars that exist in them use energy. Often more than the average person in many countries of the world. Many IT pundits forget or ignore that computers are physical objects that require resources for their construction and maintenance and that they thus have an (under-explored) ecological footprint.

Entropy revisited

by

One way of looking at our current set of predicaments is that we’ve been on a binge, consuming energy considerably faster than it can be captured and stored by Earth’s ecosystems. While fossil fuels once appeared limitless (and still do to deniers of peak oil), and though we’re literally bathed in energy (in the form of sunlight), the disappearance of the fossil-fuel storehouse accumulated over millions of years isn’t something that can be replaced with anything nearly as convenient as fossil fuels.

The peak oil crisis: revisiting the electric car

by

If one thinks of the vast amount of infrastructure the developed world has to maintain – buildings, roads, water, sewage, trash disposal, public safety, power and communications lines – one soon gets the idea that even a relatively short range electric vehicle is going to be an awful lot better than an oxcart in preserving and rebuilding the facilities we currently rely on for food and shelter during the next 100 years or so.
