The "loss" of energy to the environment is about 347 watts to turn one US gallon of water at 0 C into ice at 0 C (32 f)....The water has to give up energy to the environment for it to change phase from liquid to solid (commonly referred to as ice). Does that make it clearer?

I can understand losing energy, what doesn't seem right is the '..water at 0 C into ice at 0C. '

Water can't be both water and ice at the same time..can it? Is that a typo?

According to info from Georgia State University regarding phase change from liquid water to ice and vice versa, it takes about 80 calories per gram to change water to ice (energy given up) or ice to water (energy added). That is what I gleaned from it anyway.
