    What you have to remember is that electricity to power a city is best, most efficiently transported over large distances by HVDC power lines;

    I agree but transmission is only part of the issue. The main issue with green energy is that it is not possible to synchronize production with demand. Right now it is easy to turn up the boilers to produce more power. It is difficult to adjust the sun on demand. One of the solutions to that is to store energy and one way is to create hydrogen. Batteries won't cut it.

    By the way, my two-story house uses about 400kWh per month, or 0.013MWh per day. Turn your TV off when you go to bed.

    Is your furnace, hot water heater, cloths dryer and/or stove electric? If you are using other energy sources for that yous usage may be skewed to the lower end.

    So what if the first two submissions from someone are chosen. The important part is that they are good factual news articles. The second submission got a yellow Firehose rating. Someone must have voted for it.

    I think where the argument is lost in that the byline of the fist two articles is Dawn Kawamoto and the links have dice.com in them.

    You seem to be a player of words rather than a physician.

    I don't see how being a medical doctor has anything to do with this discussion. Did you mean physicist?

    I don't see any relation to our previous discussion. What exactly is your point?

    1. more transmission lines and switsching stations don't make the energy grid unstable. Your claim is nonsense.

    My point is that each additional transmission line and switching station adds points of failure. More points of failure means more instability.

    Where do you actually get your power from? Increase that and you are fine.

    I get mine from rivers and some fossil fuel plants. Most of the usable rivers are already being used and we are trying to move away from fossil fuel plants. We need new sources to meed the demand and wind and solar sources are not everywhere.

    Minnesota is an excellent place for solar power .

    I guess you never have had to deal with snow storms.

    However you claimed: to increase power transfered you have to increase the frequency. Which is either plain wrong or misleading. Your call.

    What I meant was that to send more power down the line frequency must be increased back to the desired level not over. he point I was trying to make is that over draw of power causes frequency variations and not peak voltage variations.

    You don't even know what this (capacitive) means, or you would not link the wrong "graph" (mixing up capacity as in storage capacity of a capacitor/battery with transport "capability" of a power line, sigh, that is such a retarded mistake).

    Again you do not understand the physics of a long AC conductor. Capacitance and inductance resist the changes in voltage. As the conductor gets longer the capacitance and inductance gets larger decreasing the capacity of the conductor to transmit power. There is a physical limit to how long an AC conductor can be.

    First of all: such nonsense is written by people like you. I doubt anyone with a degree in physics or engineering was involved in that article.

    Again, you prefer to assume facts instead of actually looking them up. The Reference is to an article from the Global Energy Network Institute so your assumption is patently false.

    Why should it not be cost effective to import electric power ... from neighbouring states that are not so far away?

    Because neighboring states have similar climate issues which limit the availability of green power.

    It seems that your solution is to build more plants and transmission lines close to cities. It is not that simple to supply electricity and recuce greenhouse gasses.

    First of all, if a point fails, the houses connected to it lose power, that is all. the rest of the grid is unaffected. Usually another endpoint gets reconfigured to support that block then.

    If that point is a switching station then a lot more people will be effected. A blackout that effected most of the east coast of the US was traced back to the failure of one small relay that started a cascade failure. A similar failure was caused by the unscheduled shutdown of a power plant. You really need to have a better understanding what a point of failure is.

    Frequencies never change. In europe they are at 50Hz fixed and in the USA at 60. If the frequency would change the grid would break down pretty fast.

    Again, you need to do more research before posting. Did you even look at the meter I linked? Did you read the explanation?

    I don't get your point about Minnesota and solar plants

    Minnesota needs electricity. We are trying to use wind and solar power. It is not a great solar or wind place. Where will they get electricity? It will have to come from further away. AC does not travel long distances very well.

    The largest synchronous grid is this one: http://en.wikipedia.org/wiki/Synchronous_grid_of_Continental_Europe [wikipedia.org] far more than 10.000 miles ...

    Sure, if you laid every power line from end to end but the distance that electricity travels from it's source to its sink is nowhere near that. Electricity is produced close to where it is used.

    With voltages in the million volt range the loss over 5000km is perhaps 8% or so ... you can google for that or do the math your self.

    If you are only calculate resistive loss and ignore capacitive and inductive loss.
    Take a look at this chart. Notice how capacity goes down as distance gets larger. At least read Wikipedia and educate yourself about the issues of long distance AC transmission. Here's a quote;

    As of 1980, the longest cost-effective distance for DC electricity was determined to be 7,000 km (4,300 mi). For AC it was 4,000 km (2,500 mi), though all transmission lines in use today are substantially shorter.

    Think about why the lines are shorter and you may understand

    When points fail the ability to supply power to the lines decreases. The power companies compensate for this by changing the frequency of the AC current not the voltage. The peak voltages are the same but the frequency is different. As frequencies increase power transmitted increases. Here is a meter showing the frequency of the UK grid. Read the explanation.

    You can upgrade current plants or simply build new plants in proximity.

    Sorry but a solar farm in Minnesota would not be very effective in the winter. New green technology is quite restricted in where it can be placed. Fossil fuel powered thermal plants can be placed anywhere but we are trying to get away from that.

    Perhaps you don't know: all europe and northern asia is interconnected in an AC grid spanning 10,000ds of miles

    Considering the earth's circumference is about 24,000miles you may be exaggerating and that exaggeration is not helping your case.
    Here is a map of the European grid. The longest straight line distance is about 3,000 miles.I guess you missed the recent HVDC lines put in between the UK and continent, Africa and Europe and several connections across the Baltic.

    1. More switches equals more points of failure. More transmission line equals more points of failure and more complex routing of power. Combined that equals more instability. Take a look at this graph and notice the number of abnormal re-routing and frequency fluctuations that is already growing. It is not going to get better in the future with a more complex system.
    2. Sure it works now but what happens when the demand doubles and we have to move power longer distances? Sure solar power is great but if we have to move the power from Texas to New York? AC is not going to cut it. Take a look at this chart notice how the capacity drops as the distances get larger? There is only so much generation capacity near our population centers causing us to have to draw power from further away. AC does not go far enough in many instances.

    Who said trucks? How about ships and pipelines?
    There are a couple of issues with the "use the grid" philosophy;
    1. The grid has a finite volume capacity. Every electric car adds the equivelant of a small house to the grid. If we convert from fossil fuels to electricity we will quickly outstrip the capacity of the existing grid. That would require more transmission line and more switching stations making the grid more unstable and increasing costs.
    2. Alternating current does not travel well over long distances. For every mile there is loss due to resistance, inductance and capacitance. Direct current helps but it too has limitations.
