It is impossible to say whether it should be nuclear energy or biofuels. A number of different energy sources are needed and they will need to be developed in order to meet the needs of society, but at the same time, greenhouse gas emissions have to be reduced.
There is an important role for biofuels, as long as they are second generation, meaning that they are produced from cellulose, as opposed to food or some other material. That is a whole other subject. However, I do agree that there needs to be more discussion of this.
