## "as little as possible" vs. "as least as possible"

3

I am not able to understand when "as little as possible" or "as least as possible" should be used.

For example, I cannot understand which is the more appropriate form in the following example

1. Energy for transportation from heat source to evaporator needs to be as least as possible
2. energy for transportation from heat source to evaporator needs to be as little as possible

2Instead of "as least as possible", people say "the least possible". – Dan Getz – 2014-12-01T20:15:23.587

1Equative constructions use as...as. Superlative constructions use least. One or the other, not both. – John Lawler – 2014-12-01T22:24:06.627

First off, as little as possible is the only option that I have ever read or used. I believe the other example you listed is grammatically correct, but it really isn't used.

Energy for transportation from heat source to evaporator needs to be used as little as possible.
The hotel did as little as possible to make me comfortable! They only gave me one towel, and there wasn't even a coffee machine
