Since calorie is a measure of energy, so what does it mean when, for example, alcohol, having “empty calories”? What kind of energy is being measured here?

What your body needs in most quantity to work is calories. However, if you don’t eat enough of other nutrients, like protein, vitamins, fiber… your body will not work properly and you might get sick.
Empty calories are calories that don’t come with those other nutrients, or come with very little of them. If you eat an orange, you’re eating calories, but you’re also eating lots vitamin C, fiber among other things. If you eat a cube of sugar, you get just calories.
