Every man his own power station is really, really dumb. Why do these people feel the need to greenwash everything they do? Centralized power generation is the only tehcnology that make any sense. Having millions of these goofballs generating electricity, and then expecting the grid operators to soak up what they can't use (and refuse to store using batteries they must pay for) is absurd and I object strongly to any regulations that allow these morons to screw up and increase the cost of my electricity. And if it's so practical, why do these thieves demand subsidies. I woudn't pay them one red cent to mess up my grid operations. These people are simply greedy assholes, using "enviromental concern" as a cover.

A system that allowed excess power generated from homes to help power businesses (that the home owners work in) makes a lot of sense. The best thing would be to make the grid a publicly held utility. Short of this it would be reasonable to allow power companies to charge a small flat rate for grid maintenance.
The only problem with selling the power at the same rate you buy it is that you do not pay for the maintenance of the power grid that delivers power. It would be reasonable to expect all power producers to help pay for that cost.

I think the idea of everyone producing as much engery as possible via solar/geo/wind at their homes is the only way to go. We will not escape a centralized power station/grid design completely. However, we can escape the chains that is fossil fuel reliance for EVERY car/truck/bus/train/etc. You could offset the national reliance on fossile fuels significantly by using electric vehicles for all possible uses. Then we would only be using oil for those technologies that have no alternative YET, like aircraft, cargo trains, ships. Then our own reserves would last us theoretically twice as long.
If everyone could power their own electric car for 90% of their commuting using home based solar or wind grid-tie systems, those Centralized power plants could theoretically save significantly by having to burn less coal/oil to create the power, thus saving more fossil fuels.
Electric cars will be here in force within a few years. They are expensive right now, well duh. It's new territory for so many uses of the technology. Check out Fisker Automotive, or HST Automotive, or Tesla Motors.
Current ranges of 200+ miles, and faster than some of the boldest supercars of your imagination for comparable prices. And they are GREEN! You could charge it from your home power plant, or grid tie system, and theoretically produce all the electricity you need for your home and car.
"Short of this it would be reasonable to allow power companies to charge a small flat rate for grid maintenance.
"
That is already the setup with Entergy power company, the minimum bill for a grid-tie solar/wind home system is $8/month as a system maintenance fee. Perfectly acceptable if you ask me. They also use a net-metering method where they pay retail rates for extra power you produce/sell back to them.

Great Post! Very informative and a great read. I saw this site during my browsing and think it may be relevant http://www.driveafrica.co.za .Keep up the great posts!

I'm not sure anyone has said here every man his own power station.
Centralized power generation is not a tehcnology, nor is it a technology. It is a manner of using a given technology. You could have a centralized power station, and they exist, of solar collectors.
I object strongly to any regulations that allow these morons to screw up and increase the cost of my electricity. And if it's so practical, why do these thieves demand subsidies.

I would be careful, in a post that has as many errors as yours, to reduce to the name calling of "morons".
Nuclear, coal, natural gas. All heavily subsidized, all technologies that work only by centralized generation and then further subsidization by cheap transmission lines.
I would suggest that some of these "greedy assholes" are actually using "enviroNmental concern(s)" as a "cover".

The American dream has changed, but for the better. In this day and age a common person would like to own a house that has not only Solar Power but also Geo-Thermal power.
I could invision a world were each person who has a car is electric and can be powered by solar power and/or wind power to recharge the batteries. Why not have turbines embeded into the wheels so as they turn they also create energy for your car?
Sadly, most car companies and Utility companies are greedy and will not change their ways untill its to late. Global warming will take effect and a downward spiral will occur. But maybe a little bit of hope can make a few people in the government change their minds and get the gears working to get this nation on track with being Green.

"Why not have turbines embeded into the wheels so as they turn they also create energy for your car?"
Because said turbines would add resistance to the wheels spinning. Keep in mind that in an electric vehicle we are supplying energy to the wheels to make them spin. So we would be wasting energy trying to use an electric motor to spin a generator. But, when we want to slow down this is OK and that is what the practice of regenerative braking is.

In today's world, man is eager to travel and discover all of nature’s hidden treasures and utilize them for the fulfillment of his or her basic requirements. A solar powered car similarly gets it's much needed fuel from the energy of sunlight.

At least a year ahead of similar efforts in the U.S and Japan, BYD began selling a plug-in electric hybrid car in China. The car, called the F3DM, plugs into a home outlet and comes with a small gasoline engine that can recharge the battery on the go. It is the first of an array of electrified cars BYD plans to introduce around the world, starting in China and then in the U.S. and Europe as early as 2010. The F3DM, their electric model, was unveiled in December, but it hasn't been selling and, as of now, the public isn't eligible to line up personal loans to get one, as it's aimed at fleet applications. However, they do plan to vamp up to mass production, but the cost is still a bit prohibitive – coming out to about $22,000 USD. Still, let us hope that some people line up for installment loans for green vehicles like the BYD electric car. http://personalmoneystore.com/moneyblog/2009/04/13/byd-electric-car-china/
