We all love a good myth. “Goldfish have a memory of only three seconds”, “Water drains backwards in the Southern Hemisphere due to the Earth’s rotation”, or maybe “A dog’s mouth is cleaner than a human’s”.  It’s all fun stuff until we actually spend cash on things that we thought will do us good but end up to be a complete waste of money.  This may come us no surprise but some very commonly believed energy upgrades seem to be just that – myths.

Rob Moddy is a fellow USGBC member who often whips out a masterful blog entry.  It’s just so hard not to share this one with you.  Here he highlights a talk given by building scientist Michael Blasnik at the Department of Energy’s National Weatherization Training Conference, particularly the problems with inaccurate computer models in determining weatherization strategies and effective home energy improvement measures. 

As originally posted on GreenBuildingAdvisor.com, this is a list of common strategies for home weatherization that don’t save much energy. If you don’t want to waste your time and money, these are the strategies to avoid or closely evaluate: (more…)

If you are going on a long trip across a couple states for a week do you drive your own car or do you rent one?  Many people rent because they don’t like adding extra mileage on their cars.  Normally renting a car is a bit more expensive than driving your own but what about renting a hybrid?  Can the gas savings potentially offset the rental car costs?  As we found out during our recent trip to Nevada and Arizona, the answer is absolutely YES! 

First, we weren’t sure what to do.  Alamo at San Jose Airport presented two options: to rent an economic mid-size car for a total of $180 per week or go for a hybrid for $220.  Considering the fact that we are thinking of buying a hybrid in the future, and the fact that our trip would leave a smaller pollution trail, we decided to have some fun and go for a hybrid – the brand spanking new Toyota Prius. 

Man it was exciting to get into one of those.  Besides the fact that it took five minutes to figure out how to start the darn thing, the ride, the comfort, the dynamics is all really a joy in that car.  Cruising at low speeds in national parks and knowing that there is absolutely no emissions coming out of the pipe was nothing short of orgasmic.  

It was a great trip but what about the bottom line on the numbers? (more…)

One would be miserable without a mask in Kathmandu

If you ever think that San Jose is polluted or is not “green” enough then keep reading… Last February I had a fortune to visit one of the most polluted cities in the world – Kathmandu. Air in Kathmandu is so polluted, you can taste it in your mouth and your skin smells like it for weeks after you leave the place. I am not even being sarcastic, it really was very fortunate circumstances that led me there and it was truly a trip of a lifetime.

Kathmandu is a capital city of Nepal. This magnificent country, situated just north of India, is beautiful, rich in culture and hosts one of the biggest treasures of our planet – the Himalayan Mountains and of course – the Everest, the rooftop of the world.

However, this story focuses on the darker side of that part of the world – overpopulation, pollution and overwhelming neglect of its environment. See, Kathmandu with all of its beauty is situated in the valley, just like the Silicon Valley but the major difference is (more…)

In the heat of San Jose summer, most people don’t want to turn on their ovens unless it’s absolutely necessary. I know I don’t.  A lot of cooking is done with a microwave, but the air inside a microwave also heats up pretty good, and let’s face it, the food just does not taste as good.

One awesome way to avoid this extra heat and unnecessary use of resources is to use a solar oven.  I first discovered it when watching a show called “Living with Ed” on Planet Green.  The guy is green out of his mind and has all these fun ways of saving energy.  He has one of these solar ovens in his backyard which of course causes regular tension with his lovely wife who is a style freak.

So what is a solar oven, you’re asking yourself.  A solar oven or solar cooker is a device which uses sunlight as its energy source. It uses no fuel and they cost nothing to run.  It’s simply a box, lined with tin foil or other material, insulated on the outside to keep the heat inside, which sits out in a strategic position in your backyard, where it will get the most sun. Ever gotten into a car – especially a black one – after it’s been sitting in the sun for a few hours? It’s extremely (more…)
