I think the way to look at it is that the vast majority of the graph is taken up by industry -- either manufacturing, or shipping/transportation. I think the actual key to making a difference is reducing consumption. Buy something once in your life rather than every few years. Go for higher quality items rather than disposable. These days, energy is the controlling factor in cost -- automation having reduced labour costs. Every time you buy something a good proportion of that cost is just energy. If you change from spending, say, $30K per year to spending $10K per year, you will reduce overall energy expenditure massively.
There are 2 problems with this: 1) our economy isn't designed to deal with a reduction in demand. 2) our culture is geared to fill up our houses with new things every year.
So that's my suggestion if you want to make a personal contribution.
Edit: There is a small line for "Agricultural Energy Use" and another for "Other Agriculture". All agricultural energy use is 1.4% and the total for all agriculture other than rice production is 0.9%. So I suppose the milk industry is some proportion of the 5% of livestock and the 2.3% of everything else. However, in some parts of the world it does contribute to deforestation. In fact, my understanding is that the vast majority of deforestation is actually for agricultural use -- but a lot of that is for chemical products as well (palm oil for use as an emulsifier in detergent as an example). Probably easiest way to deal with that is to buy local, traditional goods and to avoid luxury imported items.
