The main wasted energy is the heat generated in the bulb. If it is an incandescent bulb 70-80% of the total energy from the battery is wasted as heat.

Is heat energy produced with the light energy in a torch?
Yes. The heat and light energy in a torch are separate. From the total energy input to the torch (chemical energy from batteries), Some is useful (the light energy) and some is wasted. (heat/thermal energy) The more efficient an appliance is ,the less energy out of the input energy is wasted. For example, an appliance may be 70% efficient. If it is supplied with 100J (joules) of energy, 70J will be useful and 30J will be wasted. Along with light energy, heat energy is also produced by a torch and is wasted. Heat energy is the most common form of wasted energy in appliances. Other appliances will waste energy in the form of heat, though it may not always be obvious.
Is it always easy to collect wasted energy and use it?
Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.
