Google Vs Yahoo – Who’s Greener?

Silicon Valley is known for both innovation and hype. Recently, this pool of innovation has extended beyond bandwidth to the protection the environment. Google and Yahoo, the search engine giants, are both headquartered in the Valley and have been making headlines by greening their offices, reducing energy consumption, and carbon trading. The PR motivations are obvious, but are the green benefits really there? To set apart the hype from reality, we have analyzed the green value of both Google and Yahoo’s headquarter facilities.

We looked at the ecological services provided by green landscape features such as trees and open space (i.e. grass). Grass and trees are pervious surfaces, meaning they allow water to permeate into the ground. Roofs, sidewalks, patios, and asphalt parking lots are examples of impervious surfaces, where rainwater drains into the public storm drains. Heavy metals, oil, and other pollutants are carried off parking lots in rainwater, which often lead directly to open water habitats, where fish, birds, and reptiles live.

In terms of ecological services, trees and grass have been proven to:

1.      Remove and store carbon from the atmosphere,

2.      Remove certain airborne pollutants,

3.      Permits rainwater to seep into the ground as opposed to draining into the stormdrains, and

4.      Remove certain waterborne pollutants.

Here is a look at how green Google and Yahoo really are and how the measure up against each other.

Google Green Report
Google’s headquarters, the Googleplex, covers 44 acres, nearly 50% of which is grass or tree canopy. This is an impressive paved to open space ratio. The grass and trees on the Googleplex remove roughly 2 tons of carbon from the atmosphere per year, or 0.04 tons per year per acre. In addition, 530 lbs. of air pollution are removed per year (e.g., ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide, and particulate matter), or 12 lbs. per year per acre. It was assumed that the parking lot of the Googleplex is asphalt, and not a type of porous pavement, so the cost of managing rainfall runoff from the Googleplex is $4,474 per year, or $103 per year per acre. The abundance of grass and tree canopy on the Googleplex go a long way to offset the water quality impacts of the paved surfaces (mainly the parking lot). On average, the grass and trees reduce water pollution by 6%, as opposed to the entire property being paved.

Yahoo Green Report
The Yahoo headquarters, Yahooplex, covers 28 acres, a third of which is grass or tree canopy. This is a classic ratio of paved to open space for large office complexes in California. So far, par for the course. The Yahooplex removes 0.36 tons of carbon from the atmosphere per year, or 0.01 tons per year per acre. 114 lbs. of air pollutants are removed per year, or 4 lbs. per year per acre. In terms of rainfall, the cost associated with runoff is $9,219 per year, or $331 per year per acre. The grass and tree canopy help offset the paved areas with a 2.3% reduction in water pollution as opposed to the entire property being paved.

The final green analysis?

Google kicks Yahoo’s butt, largely due to the forethought, or luxury, of the Googleplex having 50% of its property surface providing green services. The good news for both Google and Yahoo is that over time, as trees grow, so will the tree’s canopy and mass, thus storing more carbon and removing more air pollutants.

Green next steps for both Google and Yahoo is to:
 

  1. Install porous parking surfaces, allowing up to 80% of rainwater to seep into the ground,
  2. Install green roofs, absorbing rainwater while reducing cooling costs and energy consumption, and
  3. Planting larger trees on the south and west sides of the buildings to reduce cooling costs and energy consumption.

While we crunched the hard numbers to settle the Google vs. Yahoo green debate, this report illuminates the great opportunity that awaits these two Silicon Valley giants to harness the ecological services of green surfaces.

    Green Tip – Moms Use Clothe Diapers


    Green Tip – Moms Use Clothe Diapers

    Sure, this is a little messier than the easier, disposable version. However, do you even realize the amount of disposable diapers that are filling landfills?? Cloth diapers are a choice that every mother should seriously consider. Let’s look at some facts that are quite alarming…

    Disposable Diapers Sobering Facts:

    * from birth to about 2-1/2 the average child will go through about 7,300 diapers

    * the cost for that is about $2600

    * 18 billion diapers enter landfills each year

    * disposable diapers make up about 3.4 million tons of trash

    * health risks such as fertility issues in males, eyes, nose and throat issues and even asthma-like symptoms have been connected to disposable diapers!

    * long term negative affects on animal and water life.

    * the chemicals that make disposable diapers white increase the risk of cancer

    * affect development

    * they use more water. yep. you may need to wash cloth diapers, however, way more water is used making disposable diapers!

    * a study, conducted by Anderson Laboratories in 1999 and published in the Archives of Environmental Health, found that disposable diapers release chemicals called volatile organic compounds (VOCs), including toluene, ethylbenzene, xylene and dipentene. They have been shown to have toxic health effects, such as cancer and brain damage, when used over time or high exposure.

    * they use 1.3 million tons of wood pulp. that’s about 1/4 million trees every year.

    * they take up to 500 years to break down.

    * more viruses than you want to know about…including polio, survive for two weeks or more after disposed of.

    There are many many many more reasons to avoid disposable diapers. However, I think our readers are intelligent and the above information is enough to get you thinking! Research for yourself. You will be shocked!

    Go for organic natural reusable cloth diapers. You will not only be helping the environment and saving money, you will also protect your sweet precious love bugs from harm!

      10 Tips Of Green At Home

      Lets Revisit Some of the Debates For the Global Warming Theory

      We have all heard about Global Warming, where the planet’s atmosphere is supposedly heating up. Of course, we as common citizens have no real proof, only what our scientists tell us, along with the Think Tanks and mass media. But how can we trust this when Global Warming researchers have been paid 100s of millions of dollars, and they know if they disagree with global warming theory the money stops being funded and they are out of work?

      One of the most fascinating debate points for Global Warming goes something like this; “The majority of scientists say global warming is real and we are already seeing its impact (the drought in the Western USA and the long term drought in Australia.”

      This is seriously a flawed argument and let me tell you why. You see it is irrelevant and may not even be true. After all, 55% would be most of the scientists and thus the majority, still leaving a huge contingency of doubters, with plenty of data and research to back up the opposite point of view.

      Likewise, during Copernicus’ day only one man believed the world was round, everyone else said it was flat; so the “majority of scientists” argument is irrelevant; majorities don’t mean anything. If you were one of a 100 people and they all jumped off a bridge because they agreed to, would you jump too? That is illogical.

      Now then, the second part of the argument has to do with droughts in the world. And we all know that droughts come and go. Remember the Dust Bowl “Grapes of Wrath” in the US? And in the 1950s Australia had a drought just as bad during the same period, same as the one they are having now. This one we notice more because there are more people demanding the same amount of water.

      In California, the snowpack this year is normal and anymore puts us above normal, thus, the drought theoretically is over? So, does that mean this so-called Global Warming is over? Of course, not the powers that be, behind global warming will continue to pursue this until it’s no longer in their interests. Think on this.

        When Sea Levels Rise


        When Sea Levels Rise

        It is no new scientific fact that there is a slow steady increase of temperature; we’ve been studying and recording changes for a few decades. For some reason people are only now starting to take notice of how desperate the situation is.

        Due to the increased temperature, sea levels are on the rise. It now is easier for boats full of scientists to access the Northwest Passage for research due to the polar icecaps melting . Areas that were once almost unreachable are now becoming navigational and the search for precious gems, gold, and oil is on! There is no end to mans greed.It makes sense that when the sea levels rise the ground surfaces slowly disappear. We will lose our agriculture farmlands. There may not be enough food needed to sustain ourselves, let alone other countries that we already support. Many farmers will lose their farms and their lifestyle.

        Should sea levels on the rise be a worry about freshwater? Our drinking water is not a luxury it is a necessity and is as important for people, plants, and animals. The possible damage to freshwater due to rising sea levels should be a major worry to all of us.

        For hundreds of years polar bears have been the king of the Arctic ice and roamed over vast areas of icy tundra. But with the icecaps melting away, and the distance between ice flows becoming greater, many polar bears have drowned from exhaustion before reaching shore. It also makes hunting their primary source of food, the seal, more difficult. Dying of hunger is now a probable fate for many of them.

        The total extinction of many of the world’s beloved land animals may be just around the bend due to rising sea levels.

          Homemade Biodiesel Kits Are Used by First Timers to Make Biodiesel Fuel


          Homemade Biodiesel Kits Are Used by First Timers to Make Biodiesel Fuel

          The cost of fuel has gone up again that people are thinking of alternative ways to save up on other things just so they can still continue to make use of their vehicles. Actually, there is a better way by which we can save up on fuel without having to let go of other necessities or luxuries that we have in our life. Sometimes we need all this to keep us going. When you take away one or two, you may take away your only source of happiness. So think twice before cutting off hobbies or things that you are already accustomed to.

          One thing by which we can save gas is if we make it ourselves. It is possible since homemade biodiesel kits are available for consumers to buy them. There are instructions online and there are even step-by-step videos on how to make biodiesel fuel. These are especially useful for people who prefer to see it than reading about it. The great thing about seeing how it is made is you can actually see the equipments that are being used. So you can always pattern your equipment with what is being shown.

          Since you will be doing it yourself, there are a couple of things you have to watch out for. You have to watch out for methanol and lye because it is dangerous. Aside from that, since you will be making use of heat and vegetable oils, fire is always a possibility. First time makers of biodiesel fuel should be extra careful when proceeding and like any other endeavor it takes practice to perfect it.
