The World Energy Crisis
The World Energy Crisis
The world has some decisions about sources for future energy. The increase in population and increasing demand present a problem. The cost of conventional non-renewable energy sources is on the rise. Oil, gas, water, coal, and other natural resources have a limit to their supply.
Gas, Oil and petroleum products are more expensive than ever, and the supply is running thin. Many may think that the planet may never run out of these however it seems that drilling these supplies is becoming ever more difficult. There have been three major energy crises thus far.
Due to the shortage of resources and decreased output, the cost of these energy sources has increased rapidly over the years.
How long will it take before all of these resources are exhausted? The truth is that we really do not know. Experts say that 50% of the world’s supply of available oil has been exhausted. Every day the demand is increasing and it could take mere decades to exhaust the supply of crude petroleum.
What could possibly be done about this situation? How can we as a society cope with the energy crisis at hand? What can we consumers do about this? We can all start by understanding the importance and impact that energy has in our lives. These supplies of energy should not be taken for granted. Additionally we should avoid wasting energy.
There are simple things that we could do to conserve such as getting involved with a car pool, check our car tires for proper inflation, and using fuel efficient vehicles. If we can cut down on our use of fuel and oil in everyday activities we can be further prepared for the impending energy crisis.
Another way that we can cope with the energy situation is by utilizing renewable energy sources. Solar and wind power systems are becoming ever more available. These power solutions are feasible, cost effective and environmentally friendly. In addition, you save on your power bill and help contribute towards a better future for our world.

Who’s Greener? Yahoo Vs Google
Who’s Greener? Yahoo Vs Google
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:
- Install porous parking surfaces, allowing up to 80% of rainwater to seep into the ground,
- Install green roofs, absorbing rainwater while reducing cooling costs and energy consumption, and
- 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.

What We Can All Do ?
Saving the rainforests and environment is not an easy task. It took many years of neglect, mainly on our part, in keeping the environment clean. We polluted our air and our water through chemicals and different types of bacteria and debris. We used paper products that were not recyclable and or were not biodegradable.
Rome wasn’t built in a day as the old cliche states, but we managed to ruin our planet over the years and unfortunately it will take longer than a day to rid the Earth of all the garbage we have dumped on it. It is so easy to throw a piece of paper out of your car window, instead of finding a receptacle to dispose of it, or to throw empty cans in with your regular garbage instead of separating them for the recycle pickup or to bring bottles back to the store. Let’s not forget the broken down refrigerators, t.v.s, mattresses, etc on the side of the road.
I have traveled to third world countries and it breaks my heart to see that. They have no means of garbage disposal and they certainly don’t know how to recycle. Most of the people, although poor, take pride and keep their properties neat and debris free, others do not care. The same goes for people who live here on Earth. Some are proud of what they own and others could care less.
By the inch it’s a cinch, by the yard it’s hard. If we all do our part in what ever little way, we can help improve Mother Earth and make it liveable for generations to come. Let’s start by picking up our litter, don’t let the water run when brushing your teeth, use rags instead of paper towels, carpool if you can, don’t discard items on the side of the road to make it look unsightly, but for the most part…. Be Proud Of Where You Live and What You Have!!!!!!

Copenhagen’s Spring – Scientists Ask For Higher CO2 Cuts
Copenhagen’s Spring – Scientists Ask For Higher CO2 Cuts
The International Scientific Congress on Climate Change was held in Copenhagen between 10th to 12th March and organised by the International Alliance of Research Universities (IARU): the conclusions will be published into a full synthesis report next June. Almost 1,600 scientific contributions of researchers from over 70 countries have been received, and more than 2,500 delegates attended the event.
Connie Hedegaard, Minister of Climate & Energy of Denmark said that we have “to avoid the unmanageable and manage the unavoidable” and she pointed to their example: this European country has become a net energy exporter in 30 years, creating a green growth as a stable solution of the 70s oil crisis. The messages of the congress are various. The risk that current trends of the climatic system will accelerate has a more defined and significant meaning: more probable abrupt and irreversible shifts, and we are already above the worst scenarios published by the Intergovernmental Panel on Climate Change (IPCC) in 2001. Thus the big problem is trying to at least slow down these trends if not reverse them. The experts tell us that fast regional and global mitigation strategies are needed and that the more we wait the more expensive and ambitious actions will have to be taken in the future. The fact that scientists have come to the point of saying that “Inaction is Inexcusable” means also that people who studied relentlessly for decades are frustrated by the inaction of governments, businesses and people: it is understandable given that their work has not been considered and used enough, if not at all, up to now. They are speaking louder and clearer now. The different roles of politicians and scientists have to be combined. It is time for leaders to rely firmly on science as a basis for tough and unavoidable decisions. A “societal transformation” is being asked for by a wide group of the most intelligent people on the planet including diffusion of sustainable behaviours, innovative leadership, removal of subsidies and reduction of “vested interests”. These are all very explicit messages to politicians and public alike: there is a lot of work to do between now and next December’s COP15.
In the final debate the Danish Prime Minister, Anders Fogh Rasmussen, summarised the six messages given by scientists as 6 keywords: Urgency (of the climate change challenge), Direction (long term target to be defined), Action (short term targets to be set), Fairness (to the poorest and most vulnerable), Opportunity (to originate large benefits), Governance (creation of a new global multilateral era). He stated firmly that “Business As Usual is dead” and asked his colleagues to follow Obama’s call for a Green New Deal, already asked for by public opinion and by many political parties in the world.
After the final debate with the panel of scientists an impatient Rasmussen asked for clear words on the CO2 emission target to be set in the new treaty. Prof. Daniel Kammen, Obama’s Senior Policy Advisor, stated that an entire new industrial revolution is needed to cut 1990’s CO2 emissions by 80% in 2050 and Prof. Stefan Rahmstorf agreed on this point. The feeling was that the other panelists didn’t mind… At this point the Prime Minister concluded that the ambition for COP15 can be this -80% long-term objective following the precautionary principle to avoid worse impacts (than the ones presented in 2007 IPCC report) already hypothesized by new works. Overall a more direct communication between scientists and policy makers took place in this huge meeting: now it’s time for delegations to study and prepare the ground for brave steps forward to be made by the international community in Copenhagen’s crucial Conference of the Parties #15. Will we be able to navigate better our “ship” in the solar system during the over 200 rotations it will make before then?
