Voici la question qui me guide dans mes recherches...

L’appât du gain manifesté par les entreprises supranationales et certains groupes oligarchiques, de même que le contrôle des ressources naturelles par ceux-ci, dirigent l’humanité vers un nouvel ordre mondial de type féodal, voir même sa perte. Confronté à cette situation, l’être humain est invité à refuser d’accepter d’emblée une pseudo-vérité véhiculée par des médias peut-être à la solde de ces entreprises et groupes. Au contraire, il est invité à s’engager dans un processus de discernement et conscientisation afin de créer sa propre vérité par la confrontation de sa réalité nécessairement subjective à des données objectives, telles que révélées par la science, par exemple.

Go natural, go nuclear

NOTE: I posted my comment on the hill on March 10th, but it seems they choose not to publish it.!

Interesting article in "The Hill" opinion section.  This need to be debated more.  Read my comment below after the story.  I have documented a large part of this discussion here on this blog.

Go natural, go nuclear
By Sen. Lamar Alexander (R-Tenn.) and Theodore Rockwell - 03/08/10 07:48 PM ET

The fantastic success of the movie “Avatar,” in which an interplanetary Stone Age species of people overcomes an expeditionary force that looks suspiciously like the U.S. Army, is convincing millions of Americans that the secret of success in the modern world is to “go back to nature.”

President Barack Obama mirrored this in his Inaugural address when he said, “We will harness the sun and the winds and the soil to fuel our cars and run our factories.” It all sounds so easy — free energy all around us, waiting to be harvested at little or no environmental cost, putting us back in tune with nature.

Unfortunately, it’s not as easy as it sounds. The rhythms of nature are not always our rhythms. The sun shines only 10 to 14 hours a day, while we consume electricity around the clock. We don’t want our TVs and refrigerators running only when the wind blows. Until electricity can be stored in large quantities, we will need something that can provide electrical power on demand.

So far, fossil fuels and hydroelectricity have filled the bill, but each has its limitations. We’ve already developed all the good hydroelectric sites and people object to the way they drown valleys and interrupt fish migrations. There are more old dams being torn down these days than new ones being built.

Despite new natural gas finds and new technologies for coal, oil, and natural gas exploration, the supply restrictions of fossil fuels are also well known.

These are limited resources. We already import two-thirds of our oil. Coal, oil and gas also have an enormous environmental impact. They cause pollution and are widely considered to be major contributors to global warming.

Make no mistake — solar, wind and other “renewables” have their own environmental impact as well. Solar and wind farms will occupy dozens — even hundreds — of square miles to produce ordinary amounts of electricity. The Nature Conservancy has labeled this “Energy Sprawl.” Even geothermal energy — tapping the Earth’s heat — is creating problems. In December a long-term project in Switzerland was called off because it was causing earthquakes. The developer is facing criminal charges for causing property damages. The next day an almost identical project in California was called off, also because of fear of earthquakes.

So what other options does America have? Republicans have proposed building 100 new nuclear reactors in the next 20 years, just as we built 100 reactors between 1970 and 1990. Americans have been using nuclear power for a half-century and are quite familiar with the technology. We have worked out the kinks and established an impressive record for reliability that no other power source is able to match. The average American nuclear reactor now produces electricity 90 percent of the time, as opposed to 70 percent for coal and 20 to 30 percent for wind and solar. And no member of the American public has ever been killed by commercial nuclear power — a record unmatched by other fuels.

Since the 1973 Arab Oil Embargo, there has been a highly subsidized, worldwide effort to develop wind and solar as reliable sources of electricity. (France skipped that phase, went straight to nuclear, and now sells its electricity all over Europe.) Despite favorable policies and generous incentives, neither solar nor wind has been able to establish a significant presence in the marketplace. Denmark has installed wind power for 19 percent of its electrical demand yet must dump up to 85 percent of this production abroad, sometimes at a significant loss, because wind is so unreliable. Denmark still has a large carbon footprint, since it must burn fossil fuels as a backup.

The natural case for nuclear power is compelling. Today nuclear power produces 19 percent of our electricity and 70 percent of our carbon-free electricity. Nuclear plants occupy a fraction of the land required for wind or solar and can be built in locations near where the actual power is needed rather than being transported from faraway places where wind and sunshine are stronger. And nuclear reactors operate 90 percent of the time while wind and solar are only available about a third of the time. So why aren’t we building nuclear power today?

President Obama’s recent actions have been encouraging. He has endorsed a “new generation of nuclear reactors,” appointed a commission to make recommendations about used nuclear fuel, and supported increasing loan guarantees for new nuclear plants to $54.5 billion. This is a welcome change from an administration energy policy that looked more like a national windmill policy, which was the equivalent of going to war in sailboats.

Polls show that the American public increasingly favors nuclear power. Still, the fear-mongering and prejudice against the technology persist. A nuclear power plant is not a bomb. It cannot explode. Ninety-seven percent of a spent fuel rod is recyclable. The French store all their “nuclear waste” from 30 years of producing 80 percent of their electricity beneath the floor of one room.

When properly understood, nuclear energy is as clean and natural as wind, sunshine or any of the supposedly more “natural” alternatives. The tremendous power that lies at the heart of the atom is part of nature as well.

Alexander is the Republican Conference chairman. Rockwell is a member of the Health Physics Society, a fellow of the American Nuclear Society and a vice president and a founding director of Radiation, Science and Health Inc.

My comments to this story:
All this is known and very logical but there a more problems to be addressed.

When you have nuclear power operators, investing in wind and solar and stopping the construction of new reactors, because this would push prices of electricity up and push up the profit margin more than building new reactors. 

The problems in our societies are:
 - A lack of common sense policies
 - Profit only logic
 - Fear of the unknown

A good portion of this, is caused in my humble opinion, by a lack of a proper education in science by the people in power and the tendency of the human species of working for his own profit instead of the profit of the community.

This is what we saw in the Avatar movie, a sense of community, working for the group before ourselves.

I have heard so often the word "socialism" when referring to the nuclear power in France. 

Those misconception and problems needs to be address at the same time as educating oneself to basic science.

One thing we often forget to mention. is that we use in average 90% of fossil fuel for all of our energy use on this planet.  Therefore it is safe to assume that 90% of the money spent on an energy system will consume fossil fuel to build and maintain it, until the percentage of our power base is switched to a non-fossil fuel base power. 

This is the main reason why we need to have high energy density energy sources that give power near to 100% of the time.

We may not have much time left in term of fossil fuel reserve to build the nuclear power base infrastructure needed to power 7+ billion souls to a descent energy level we are used to have in our industrialized society.

Good luck to us all.

Best regards,
