There have been a lot of studies and comparisons on the savings of CO2 emissions when pv solar panels are used in place of electricity from a utility company; however, since different solar panel manufacturers use different manufacturing techniques, and different kinds of power plants produce differing amounts of CO2, the results of these comparisons can vary widely.
Dishwashers vs hand washing is one of those debates that rages though the green community and you can find plenty of facts, research and evidence to support both sides.
Trouble is, that most people try to compare apples and (some un-specified fruit that proves the desired outcome) so we here at greenknowe.org set out to do our own first hand practical kitchen analysis.

If you buy your car home charger through Nissan's program, you must use one of their installers. Their minimum price with installation is around $2500, which can be excessive if you only need a little bit of electrical work done.
Another option would be to buy your own home car charger from Leviton:

Many of you are already familiar with my on going battle with Tetra Pak. Here is a new project for everyone. I thought this would be a good project because I found very little in the way of recycled pencil boxes when looking for products for the eco school supply product list. Most pencil boxes were small, kitsch and over priced.

One of the most frequent questions I get about my Leaf is "how far does it go", or equivalently, "how much electricity does it use?" Both questions hinge on the electrical consumption of the car. "How far does it go" is equal to total capacity (24 kW·h) divided by consumption, and "how much electricity does it use" is equal to your total driving distance times consumption. The leaf expresses electrical consumption by the reciprocal quantity, miles per kW·h, so those are the units I will use as well.
PG&E has a great online utility that will show you your hour-by-hour electrical consumption, directly from your smart meter. The image below is a screenshot of the first full charge of my leaf, done around 4am after driving to work and back the day before.
I did not get it in time for Christmas, but my long wait is over -- my Leaf has arrived -- in the garage, plugged in and charging up! I've been on Nissan's waiting list since June of last year, but I have actually been looking forward to buying an electric car for much longer than that. Back when my previous car was about seven years old, I fi
So being part of the riot4 austerity and just generally wanting to live a better, healthier life has led us to try and spend more time biking around. Most of our local errands we accomplish on foot but what about errands that take us out of town but arnt so far that we need to take the car? What about those intermediate distance shopping trips? How to get the goods home?
First came incandescent bulbs, then CFLs now we are onto LEDs. With this we have changed what sort of lighting fixture we look for in our home.
