Verified step by step guidance

1. Understand that the question asks for the energy provided by alcohol in kilocalories per gram, which is a measure of how much energy the body can obtain from metabolizing alcohol.
2. Recall that macronutrients provide different amounts of energy: carbohydrates and proteins provide about 4 kcal/g, fats provide about 9 kcal/g, and alcohol provides a distinct amount.
3. Recognize that alcohol is not a macronutrient like carbs, proteins, or fats, but it still provides energy when consumed.
4. Remember the standard energy value assigned to alcohol in nutrition, which is commonly used in dietary calculations and food labeling.
5. Conclude that alcohol provides 7 kilocalories per gram, which is between the energy values of carbohydrates/proteins and fats.
