Until the 1990s, there were few reliable observations about movement at the scale of the entire universe, which is the only scale dark energy effects. So dark energy could not be seen until we could measure things very, very far away.
Some authors have conceptualized depression as a "depletion syndrome" because of the prominence of fatigability; they postulate that the patient exhausts his available energy during the period prior to the onset of the depression and that the depressed state represents a kind of hibernation, during which the patient gradually builds up a new story of energy.
So if somebody wants to build a coal-powered plant, they can; it's just that it will bankrupt them because they're going to be charged a huge sum for all that greenhouse gas that's being emitted.
Then idiots talk....of Energy. If there is a word in the dictionary under any letter from A to Z that I abominate, it is energy. It is such a conventional superstition, such parrot gabble! What the deuce!....But show me a good opportunity, show me something really worth being energetic about, and I'll show you energy.
Mr Churchill, to what do you attribute your success in life? Conservation of energy. Never stand up when you can sit down. And never sit down when you can lie down.
