AskPablo: Active Solar

| Monday December 11th, 2006 | 1 Comment

breadbox.gif
This week I am going to run the numbers on a hypothetical active solar heating system. Active solar differs from passive solar in that it requires mechanical means for moving the heat energy (pumps, fans, etc.). Passive solar can be as simple as opening your curtains to let some sunlight in.

Not your Momma’s Biodiesel

| Monday December 11th, 2006 | 1 Comment

Fatbike.jpegNow this is the essence of waste into food, or food into fuel, or something: According to Shortnews.com, a Norwegian businessman who now lives in Miami, named Lauri Venoy, is negotiating with Jackson Memorial Hospital to obtain more than 11.5 litres of human fat obtained from liposuction operations every week. Normally burned, Lauri can turn it into truck fuel.
This could be for the Goth movement what soybean oil was for the hippie movement. I can see the sticker now on the VW Jetta: 100% powered by Human Fat. [link here]

TXU Shareholders File Resolution Against New Coal

| Thursday December 7th, 2006 | 2 Comments

coalpower.jpgThis is what owning shares in a company is all about: Major shareholders in TXU (Texas) filed a resolution advising the company against building new coal plants in Texas. The investors include pension funds as well as religeous organizations who are precisely the kind of investors who can safely make such resolutions. The reason is that forcing the company to innovate, encourage efficiency, and/or invest in alternative non-polluting fuels may be costly in the short term, but ultimately results in a stronger offering for investors as well as society and the environment. Short term investors are inherantly harder to convince of this.
Ironically, because of tax breaks and other misguided government incentives, coal plants, supposedly now referred to as “clean coal” have suddenly become a lot cheaper to build (see this TreeHugger post for some Niagra Falls irony). Environmental Defense has more about the dituation with TXU. Read it here.

TreeHugger on Oprah, with Bonus Appearance on Rush Limbaugh

| Wednesday December 6th, 2006 | 3 Comments

rush_limbaugh.jpgPresidio Grad and TreeHugger TV leader Simran Sethi made it to the Oprah Winfrey show yesterday with a prerecorded segment on greening your Christmas tree. Watch the piece on YouTube here. It’s short, but fantastic. The show’s other star was Al Gore who used the opportunity to talk about climate change and “An Inconvenient Truth”.
In the shadows, however, was lurking the infamous Rush Limbaugh who had this to say about the episode: [transcript][audio file]

Shi Zhengrong: More Proof of Riches in Green

| Wednesday December 6th, 2006 | 1 Comment

shijen.jpgIf money can’t motivate the average person then I’m at a bit of a loss, but let it be at least some of the inspiration toward building a greener economy. TreeHugger mentioned a while ago that China’s richest person made her fortune by importing waste paper from the United States and recycling it. Now, Tom Friedman reports on the success of Shi Zhengrong’s Suntech Corporation. He’s China’s 7th richest person (who’s really counting at that point?) with an impressive billion dollar fortune. The source? Solar panels. I agree with Tom Friedman when we says that this is both a heartening sign for China’s future as well as a wake up call for the US energy sector.

What Would it Take to Move you to Bentonville?

| Tuesday December 5th, 2006 | 0 Comments

Joel Makower has an excellent post about a dream job with Wal Mart. The “Corporate Partnerships Project Manager – Wal-Mart” position is set to be filled soon by Environmental Defense, and requires moving to Bentonville, AR. It might take a rare breed of person to satisfy all the criteria needed to fill the position, and still be happy with small town American life. Or is it? Drop over to Joel’s site and apply if you think you’ve got what it takes.

AskPablo: R-Value

| Monday December 4th, 2006 | 6 Comments

insulation.jpgMany years ago some guy decided to leave a legacy behind. His goal was to confuse the heck out of us. But with a little patience I will try to clear the muddy water on our way to understanding R-values. R-values are a measure of thermal resistance, or the ability to insulate. You will most commonly find R-values on insulating materials at your local building supply store. R-values range from 1 (for a single-pane window) to 7.2/inch (for polyisocyanurate foil-faced panels) or as high as 10 for high-tech silica aerogel and 30 for vacuum insulated panels. But what does R-value mean? Well, here comes the confusing part: R=ft²-°F-h/Btu (I am using the non-SI definition here because it is most common in the US). What?

RAN vs. Car Culture Equals a Communication Breakdown

| Thursday November 30th, 2006 | 4 Comments

gm-ran.gif
Effective communication is not always easy. However, in order to accomplish anything when controversy or new ideas are on the table you’ll get nowhere if you can’t make yourself understood without souring the air. Speaking of the art of communications, I’m walking gingerly to articulate this post.
Yesterday morning Rick Wagoner, General Motors CEO, gave a keynote address to open the LA Auto Show. The main gist of the speech was to outline GM’s commitment to non-gasoline powered automobiles, in particular electric ones. His company is definitely not yet what I might call a “leader” in efficiency or green thinking, but they are making real steps in that direction. In particular, they announced that a plug-in Saturn hybrid is on the way, and rumor has it, something a lot more exciting will be announced in January.
At the very end of Wagoner’s speech, two official looking men took the stage and the following ensued: Click Here to watch video. The entire room was taken for a ride – who the heck were these guys? Read on for my reaction…

Johnson Controls Sustainability Training Goes Online

| Tuesday November 28th, 2006 | 0 Comments

jon_con.jpgOf all the companies that should be leaders in green building and retrofitting, Johnson Controls should be at the top of the list. They’re starting to get there, in fact there is now a “path to sustainability” on the front page of their website. Even better, the company now offers a web based “Sustainable Energy Education & Communications” program to other companies as well as their own employees. Here’s a PDF about it. The web based version of the progam is highlighted here.

How An Airport “Cell Phone Lane” is a Green Choice

| Wednesday November 22nd, 2006 | 5 Comments

cellcar.jpgSometimes it’s the little things that count. At Detroit Airport, and apparantly in San Jose as well, there is now a special lane for cars waiting to pick people up known as the “Cell Phone Lane”. The idea is that instead of circling endlessly in bumper to bumper traffic, you pull in to this special lane a fair distance from the terminal, and wait for a call. That’s smart and saves a fair amount of emissions and headaches alike. Ideally, they should put up a sign saying “if you’re here for more than 30 seconds you should turn of your motor alltogether”. No word on that. Via Gizmodo.

All About the Carbon Disclosure Project

| Wednesday November 22nd, 2006 | 0 Comments

CDP2logo.gif
Here’s a little tid bit you ought to be aware of – the Carbon Disclosure Project is a massive repository of informaion on greenhouse gas emissions voluntarily disclosed by over 2000 major companies. It’s 4th edition launched in September and offers detailed survey responses from each company involved.
But what makes a company, especially in the United States, voluntarily take the time to disclose their carbon footprint? It’s a process that might presumably reveal secrets afterall. It’s not just goodwill – a company that is prepared to provide this information voluntarily is a company that will be far more prepared to present it if and when government regulations require it. It also makes for a more transparent public relations with shareholders and critics alike, and that’s almost as good as a reduction in emissions.
