**3.4 Energy smart**

Energy is also a limited resource which must be used sensibly to secure the safe, healthy and nutritious food for the growing population in country. Promotion of biofuels, high efficient agro machineries, residue management and conservation practices (reduce tillage) are the important energy smart interventions to conserve energy and reduce GHGs [33]. Use of biogas systems through manure slurry from intensive dairy initiatives is also appreciated as energy smart approach in most part of the world (**Figure 3**).
