Does non-alcoholic beer have fewer calories than regular beer?
Yes. Alcohol is the biggest source of calories in beer, at about 7 calories per gram. Take it out and most of the energy goes with it. Heineken shows this well: the 5% Original has 42 calories per 100ml, Heineken 0.0 has 21.
Per pint the gap is larger. The NHS puts a pint of 5% beer at up to 222 calories. A pint of Enhanced Lager is about 97.
Where the calories come from
Once the alcohol has gone, nearly all the calories come from carbohydrate left over from the malt: starches, and some sugar. Carbohydrate carries about 4 calories per gram, against 7 for alcohol. A beer with more leftover sugar, such as Erdinger Alkoholfrei at 3.6g per 100ml, tends to sit at the top of the table.
The trace of alcohol in a 0.5% beer barely counts. A pint holds about 2g of alcohol, around 16 calories.

What to check on the label
Look at Energy, given per 100ml, and multiply by the size of the can: 4.4 for 440ml, 3.3 for 330ml. Then check of which sugars, because two beers with similar calories can carry very different amounts of sugar.
