Same reason the sun shines at night.

As you can tell by the reply by V50, you really should try to make a better opening post. Where have you read this? Post links please whenever asking technical questions. And if you post those links, will the answer be self-evident?

Wrong way around. The water has more energy. You have to add energy to melt the ice.

I am making blackberry wine fermentation generates heat. I have water frozen in 2 liter soft drink bottles. When wine gets up to 72 deg F it is too hot it needs to be 68 deg all the time but best I can do is put bottles of ice in the wine to cool it down. A bottle of ice will cool the wine down to about 61 degrees. I had 5 bottles of ice frozen over a period of 8 days all the ice was used up in 6 days and the freezer is not able to freeze ice bottles fast enough so I have been using bottles that are only 5% or 10% frozen to cool wine. A bottle that is not completely frozen only cools wine down to about 68 deg F. It takes about 4 hours for a solid piece of ice to completely melt lowering wine temperature about 6 deg colder than 32 deg water bottles.

Yes, it is because the freezer is extracting heat (energy) from the water / ice. The water takes a long time to freeze, because there is a lot of heat to extract while it freezes (called latent heat). So the ice has less energy than liquid water.

You must be thinking heat is energy and cold is absence of energy.

I am thinking ice has the ability to remove more heat than 32 deg water.

I remember college physics teacher explaining, it takes more energy to make ice than cold water the same temperature. That was 50 years ago. I don't remember WHY it takes more energy to make ice?

Yes, you remember correctly. But the energy required to freeze the water does not end up in the ice. The work (a form of energy) required to extract the energy from the water gets chucked out the back of the freezer as heat.
As for WHY, you will have read the latent heat Wikipedia energy I posted - sorry, Wikpedia articles are never great, but I don't have the energy(!) to explain it all.myself.
