For Dell, going carbon neutral means outsourcing the dirty work

Computer Keyboard Al Gore has been busy for the last several years with the debut of Inconvenient Truth and winning a Nobel peace prize. His message has made its way to larger companies like Dell, who are seeking to reduce their carbon footprint in the world. Considering the number of computers Dell manufactures on a daily basis, a significant overhaul of businesses processes would make sense. Instead, Dell is paying someone else to deal with the problem without changing it’s overall approach to business.

Dell claims that it is already carbon neutral, but it achieved that milestone largely by purchasing renewable energy credits, according to the Wall Street Journal. That means the company itself isn’t doing much to reduce how much carbon it’s generating in the environment.

Instead, the money it invests in renewable energy credits is used to fund initiatives like building wind turbine farms.

Voltree rips clean coal to shreds, makes electricity from trees

Hardwood Tree Forest What grows around us everywhere, draws power from a virtually limitless energy source and is green by nature? Trees. Voltree, a new startup based in the U.S., noticed that too and is doing something about it in a potentially big way. Right now the company is working to create a mesh network of wireless sensors that detect forest fires and draw power from a host tree. That makes power from clean coal seem awfully dirty.

Though Voltree is starting with its sensor array, drawing power from trees opens up a whole new approach to power generation applying some green principles. The company’s Early Wildfire Alert Network (EWAN) would track humidity and temperature in remote forested locations, according to Voltree.

LED technology, the bulb of the future

Light Bulb Forget large scale renewable energy solutions. It’s time to think smaller. It’s time to think about replacing our energy-hungry, wasteful light bulbs for a more efficient, longer lasting bulb.

The advancements in LED (light-emitting-diode) technology will not only change the way our world uses light, but also sees light. LED technology is certainly not the newest innovation on the market. In fact, LED technology has been around since the 1960’s. Most recently, it has been used in digital clocks, watches, remote controls and other digital devices. Perhaps its greatest contribution, however, will be in the light bulb.
