How the USA Can Cut 28% of Greenhouse Gases

A new study has been released that looks at how the United States can cut 28% of their greenhouse gas emissions. They looked primarily at the wastefulness of energy use and notice problems that can be solved from the level of the consumer, to the landlord, and to every level of government. By knowing the problem, we can begin to solve and, indeed they have a couple suggestions.

“What the report calls out is the fact that the potential is so substantial for energy efficiency,” said Ken Ostrowski, a leader of the report team. “Not that we will do it, but the potential is just staggering here in the U.S. There is a lot of inertia, and a lot of barriers.”

The country can do the job with “tested approaches and high-potential emerging technologies,” the study found, but doing the work “will require strong, coordinated, economywide action that begins in the near future.”

Make Your Telecommute Even Greener

Telecommuting is good for the environment because it means that people don’t have to get in a car and not move during rush hour. Granted they can take transit or bike, but some people like the “freedom” of getting into slow moving roadways. Telecommuters have it even better because they can wear slippers and pajamas all day.

Over at Web Worker Daily, they recently asked readers how to make web working more green.

I don’t claim to have all the answers, but there are a few areas that seem to be obvious candidates for a web worker focus. Energy consumption is one: if we swap cars for more computers, our carbon footprint doesn’t go down as much as it might. We’ve looked at cutting down on vampire power as a way to attack this in the past. Virtual machines can also offer computer – and power – savings.

Google to Make Solar Energy Cheaper than Coal

Google logoGoogle is at it again, we’ve covered Google quite a bit, more than any other company I think. It’s just so nice to see a company with billions of dollars at their disposal directing their energy at improving the world (and yes, I know that Google is nowhere near perfect and Sun is more the environmentally friendly tech company).

This time around they are contuning their solar power drive by investing in companies that will encourage the use of renewable energy. They emphasize solar power, but they are not limiting the hundreds of millions of dollars they want to invest in solar power.

“Our goal is to produce one gigawatt of renewable energy capacity that is cheaper than coal. We are optimistic this can be done in years, not decades,” Larry Page, Google’s co-founder and president of products, said in a statement.

One gigawatt can power a city the size of San Francisco.

Google is seeking to capitalize on the recent excitement among Silicon Valley entrepreneurs to apply the risk taking that computer, biotech and Internet businesses are famous for to the field of alternative energy production.

Google’s latest moves come as the price of a barrel of oil nears $100 and coal, which produces 40 percent of the world’s electricity, faces regulatory and environmental pressures that could drive up prices.

SkySails Start Sailing to Save Fuel

skysailFootball field sized sails are finally hitting the waves, last year we mentioned SkySails initiative to sell their sails to large tanker fleets. December will see the first ship equipped with the extra-large sails head out on its maiden voyage.

The SkySails system consists of a towing kite with rope, a launch and recovery system and a control system for the whole operation. The control system acts like the autopitot systems on an aircraft, the company says. Autopilot software sends and receives data about the sail etc to make sure the sail is set at its optimal position.

The company also says it provides an optional weather routing system so that ships can sail into optimal wind conditions.The kites typically fly at about 1,000 feet above sea level, thereby tapping winds that can be almost 50% stronger than at the surface.

Chocolate Good for the Earth

Here’s some good news for all you chocolate lovers out there: a chocolate byproduct can provide fuel!

North western English firm Ecotec has taken waste from the chocolate manufacturing process, turned it into bio-ethanol and mixed it with vegetable oil to produce biodiesel.

Some biofuels have come under fire for either diverting much-needed food crops or leading to massive deforestation as land is cleared to grow crops specially for biofuel production.
