7Solar power satellite — A solar power satellite, or SPS or Powersat, as originally proposed would be a satellite built in high Earth orbit that uses microwave power transmission to beam solar power to a very large antenna on Earth. Advantages of placing the solar… …
8Intermittent power source — [ Erie Shores Wind Farm monthly output over a two year period] An intermittent power source is a source of electric power generation that may be uncontrollably variable or more intermittent than conventional power sources, and therefore non… …
9Nuclear power debate — For nuclear energy policies by nation, see Nuclear energy policy. For public protests about nuclear power, see Anti nuclear movement. Three of the reactors at Fukushima I overheated, causing meltdowns that eventually led to hydrogen explosions,… …
10Insertion loss — In telecommunications, insertion loss is the decrease in transmitted signal power resulting from the insertion of a device in a transmission line or optical fiber. It is usually expressed relative to the signal power delivered to that same part… …
