The actual output power would be the capacity factor multiplied by rated output. And I don't understand why you keep emphasizing the capacity factor, it just makes your argument weaker, you say for solar it's 20%, so the the percentage of world wide energy needs provided by photovoltaic is just .00002%, assuming the numbers you proved are correct. > > You multiply the capacity by a capacity factor, which for big > thermo-electric plants (both nuclear and coal) is around 80% and then > multiply that by the number of hours in a year to get the estimated annual > output. > That would give you the amount of energy the plant would produce in a year. And to operate all human technology on this planet would require 1.5*10^17 watts of POWER. To operate it for one hour would require 1.5*10^17 watt-hours of ENERGY. To find out how much energy would be required to operate it for one year you would take 1.5*10^17 watt-hours AND THEN MULTIPLY THAT BY THE NUMBER OF HOURS IN A YEAR. Therefore if you're interested in percentages, like the percentage of the energy required to run the world that photovoltaics provide, it doesn't matter how many hours there are in a day because the 2 terms would cancel out. So even if there were 6.02*10^23 hours in a year, the percentages would remain the same. > You really don't get it do you. Are you dense or just argumentative? Chris, You have just vividly demonstrated that you don't understand the difference between energy and power, something that is taught during the first week of high school physics, and you can't seem to figure out how to multiply 24*365, so it makes we wonder if you are the one we should look to in deciding what our long term energy policy should be. > > Capacity measures the nameplate potential to produce power - a solar > panel with a 1kw capacity can produce a kilowatt of power if the sun is > shining on it at full flux.

Not even in a billion years? Who did you determine that? John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
