The efficiency of approximately 15-year-old oil heaters can vary depending on their maintenance and usage. Generally, older oil heaters may have an efficiency rating of around 60-70%, meaning that 30-40% of the energy from the oil is lost as waste heat. This is lower than the efficiency of newer models, which can reach up to 90% efficiency. It's important to have older oil heaters regularly serviced and maintained to ensure they are operating as efficiently as possible. Consider upgrading to a newer, more efficient model for better energy savings. **

The efficiency of incandescent light bulbs is relatively low compared to other types of lighting. Incandescent bulbs convert only about 10% of the energy they consume into visible light, with the rest being emitted as heat. This makes them much less efficient than newer technologies such as LED or CFL bulbs, which can convert up to 80-90% of their energy into light. Due to their low efficiency, incandescent bulbs are being phased out in many countries in favor of more energy-efficient options. **
