Most of the technology needed to shift the world from fossil fuel to clean, renewable energy already exists. Implementing that technology requires overcoming obstacles in planning and politics, but doing so could result in a 30 percent decrease in global power demand, say Stanford civil and environmental engineering Professor Mark Z. Jacobson and University of California-Davis researcher Mark Delucchi.

To make clear the extent of those hurdles – and how they could be overcome – they have written an article that is the cover story in the November issue of Scientific American. In it, they present new research mapping out and evaluating a quantitative plan for powering the entire world on wind, water and solar energy, including an assessment of the materials needed and costs. And it will ultimately be cheaper than sticking with fossil fuel or going nuclear, they say.

The key is turning to wind, water and solar energy to generate electrical power – making a massive commitment to them – and eliminating combustion as a way to generate power for vehicles as well as for normal electricity use.

The problem lies in the use of fossil fuels and biomass combustion, which are notoriously inefficient at producing usable energy. For example, when gasoline is used to power a vehicle, at least 80 percent of the energy produced is wasted as heat.

With vehicles that run on electricity, it's the opposite. Roughly 80 percent of the energy supplied to the vehicle is converted into motion, with only 20 percent lost as heat. Other combustion devices can similarly be replaced with electricity or with hydrogen produced by electricity.

Jacobson and Delucchi used data from the U.S. Energy Information Administration to project that if the world's current mix of energy sources is maintained, global energy demand at any given moment in 2030 would be 16.9 terawatts, or 16.9 million megawatts.

They then calculated that if no combustion of fossil fuel or biomass were used to generate energy, and virtually everything was powered by electricity – either for direct use or hydrogen production – the demand would be only 11.5 terawatts. That's only two-thirds of the energy that would be needed if fossil fuels were still in the mix.
 
The Scientific American article provides a quantification of global solar and wind resources based on new research by Jacobson and Delucchi.
Analyzing only on-land locations with a high potential for producing power, they found that even if wind were the only method used to generate power, the potential for wind energy production is 5 to 15 times greater than what is needed to power the entire world. For solar energy, the comparable calculation found that solar could produce about 30 times the amount needed.

Awesome!! Maybe we should be fund-raising or lobbying.. =) Great Article, OR!!

You read a article posted by old crock and shout awesome, you got to be a moron, I guess we got triplets now, old crock, chrissy and tobe.

Every article I have read of Old Crock's has only shown old crock to be a fool, are you a moron who only reads the last post of a thread and ingores everything else.

Whats wrong with you, old crock is proven to be a big moron, tied with chrissy, and now you want to make it a threesome.

You cant even tell us a basic fact of what you find gnarly and awesome dude!

100% alternative is an impossiblity.

How much energy and what types does it take to produce one ton of fiberglass.

The link is not to an article, it is to a press release, literally an advertisment to donors for stanford univeristy

The report written by jacobson and delucchi is not availble, we cannot read the report

post the report

Special Interactive Feature Powering a Green Planet: Sustainable Energy, Made Interactive
The Web-only article below is a special rich-media presentation of the feature, "A Path to Sustainable Energy by 2030", which appears in the November 2009 issue of Scientific American. It was created by FlypMedia.com.

The article is a rational and lucid presentation of one way to totally go alternative for the whole world. It is in the November 2009 issue of Scientific American for any interested in it.
 
Show why.

In spite of all these "advances" people claim in "green" (which has yet to be proven) energy, the "wind farms" in Oregon only produce a very very small portion of their energy needs ... that's just one example of such ... every place that only produces "green" energy has to buy more from those who produce coal energy. If you want a real solution to energy needs, nuclear is the only way, all others are just toys in comparison.
 
It's possible but not probable. It's not productive to think in such absolute terms with respect to energy supply or demand. Applications have advantages and disadvantages based on science and economics.

We like to imagine "perfect world" situations- and we should strive for such. But within that quest there must also exist a desire to understand the status quo of existing technologies and their relevant place in today's world.

Solutions aren't achieved unilaterally, but through a team approach. Acknowledge strengths, recognise weaknesses, and build a model that will in time drive you to the goal.

The end. :D

Old Crock as dumb as a rock going off half cocked, I alread stated that you would not post the report and now you post an article. All your sources are a Crock of shit, literally speaking.

Old Crock why do you refuse to post the report you cite?
 
As pointed out, the original article is in the November issue of the Scientific American. However, here is another article based on that article;

100% Renewables by 2030 for Less Than Fossil Power: A Case is Made | SolveClimate.com

Wind: 51% of power needs. This would require 3.8 million large new wind turbines worldwide. Currently, less than 1% of that amount is installed.

Solar: 40% of power needs. This calls for 89,000 photovoltaic installations and concentrating solar power farms, all at 300 megawatts each. Like wind, the world is at less than 1% of that target.

Water: 9% of power needs. This would require the deployment of numerous "mature water-related" technologies, including 490,000 tidal turbines, 5,350 geothermal plants and 900 hydroelectric plants. For hydroelectric, the world has 70 percent in place. For geothermal, there are less than 2% of the needed facilities installed, and turbines, less than 1%.

The authors assume that most fossil fuel transportation can be replaced by battery and fuel-cell vehicles. They also say that resource availability for the plan isn't a problem.
 
A Plan to Power 100 Percent of the Planet with Renewables: Scientific American

A year ago former vice president Al Gore threw down a gauntlet: to repower America with 100 percent carbon-free electricity within 10 years. As the two of us started to evaluate the feasibility of such a change, we took on an even larger challenge: to determine how 100 percent of the world’s energy, for all purposes, could be supplied by wind, water and solar resources, by as early as 2030. Our plan is presented here.

Scientists have been building to this moment for at least a decade, analyzing various pieces of the challenge. Most recently, a 2009 Stanford University study ranked energy systems according to their impacts on global warming, pollution, water supply, land use, wildlife and other concerns. The very best options were wind, solar, geothermal, tidal and hydroelectric power—all of which are driven by wind, water or sunlight (referred to as WWS). Nuclear power, coal with carbon capture, and ethanol were all poorer options, as were oil and natural gas. The study also found that battery-electric vehicles and hydrogen fuel-cell vehicles recharged by WWS options would largely eliminate pollution from the transportation sector.

Our plan calls for millions of wind turbines, water machines and solar installations. The numbers are large, but the scale is not an insurmountable hurdle; society has achieved massive transformations before. During World War II, the U.S. retooled automobile factories to produce 300,000 aircraft, and other countries produced 486,000 more. In 1956 the U.S. began building the Interstate Highway System, which after 35 years extended for 47,000 miles, changing commerce and society.

Is it feasible to transform the world’s energy systems? Could it be accomplished in two decades? The answers depend on the technologies chosen, the availability of critical materials, and economic and political factors.

Key Concepts


  • Supplies of wind and solar energy on accessible land dwarf the energy consumed by people around the globe.
  • The authors’ plan calls for 3.8 million large wind turbines, 90,000 solar plants, and numerous geothermal, tidal and rooftop photovoltaic installations worldwide.
  • The cost of generating and transmitting power would be less than the projected cost per kilowatt-hour for fossil-fuel and nuclear power.
  • Shortages of a few specialty materials, along with lack of political will, loom as the greatest obstacles.


In December leaders from around the world will meet in Copenhagen to try to agree on cutting back greenhouse gas emissions for decades to come. The most effective step to implement that goal would be a massive shift away from fossil fuels to clean, renewable energy sources. If leaders can have confidence that such a transformation is possible, they might commit to an historic agreement. We think they can.
 
During World War II, the U.S. retooled automobile factories to produce 300,000 aircraft, and other countries produced 486,000 more.
What an absolutely asinine example.

Warfare produces not one dime's worth of added value to anything for anyone not using the tools of warfare. And it does so at great economic expense to the producers.

I have serious reservations about the intellectual prowess of a publication that could seriously peddle such a flimsy and easily refuted analogy.
 
A doable and needed plan.

So this is what qualifies as debate or an arguement by Old Crock, a press release. I have followed all the links in this thread, nothing, an offer to subscribe to Scientific America and a press release.

What gives Old Crock, this is the best green energy has, secret reports.

You know why we will never see the report, because the report is seriously flawed, I can tell you with a 100% accuracy the report does not address the transmission lines. I can also state with a 100% certainty that authors do not address the energy needed to produce fiberglass, steel, or copper.

What a waste of an electrical generator, to sit behind a big propeller not being used for 94% of the year. Funny thing is all those electrical generators sitting idle can be hooked up to a nuclear plant and produce 100,000% more power than if the wind were blowing.

I invented the perfect green car, it runs on earthquakes, you just sit in it and when the big one comes you get a free ride to work.

So how about it Old Crock, you cant even substantiate the claims you make in your own threads, where are you on this one.
 
Fantastic !
40 years late.
Unfortunately there is no 2030.
NO. I don't do Mayan calendars or Biblical fairy tales.
I'm a statistical sort of scientific asshole.:redface:
This movie is nearly over.........
