I believe that a 100% reduction means that you have nothing left, but others have said it cuts it in half. To me that math doesn't add up, since half=1/2=.5 and .5 is the same as saying 50%...therefore, a cut in half cannot be a 100% reduction.

As I stated above I know that 100% reduction equals zero. What puzzles me is how others can think it is a reduction by 1/2. The others I refer to can be quite smart at times, and very adamant about their answer - but just being adamant doesn't make you right...but it does tend to make others stop and think, am I crazy or missing something. This question is more about ensuring that I am not missing something. Sort of like doing a math problem wrong several times, but when a friend looks over your shoulder you find your error and do it right.
If all new Fed Buildings will reduce their fossil fuel energy use by 100% by 2030, then by 2030 they will use 0 energy produced w/ fossil fuel!
I can't wait to see that!

You are absolutely right. It is zero.

e.g.
100 = 100%
100 x (1-100%)
= 100 x 0
= 0
∴100% reduction in something = 0 (for all time)

it is reduced to zero or else it would be a 50% reduction. if you reduce it by 100% you take 100% away from it, leaving it with 0%.

100% is equivalent to 1. If a whole then represented by 1 is reduced by 1 then nothing will be left. You're right in believing then that a 100% reduction leaves nothing. Other than that which you already believed is false.

See, please. What is 100% of N? 100% of N is N which when reduced by 100%, N becomes N -- N = 0 (not 0%).
Do you see? 0% of every number is always 0 but 100% of every number is different.

Look at it this way 100 - 100 = 0
