Part B:
- Many clean technologies have been recently implemented into our lives.
- Examples of clean technologies in daily life are: Solar heating devices, Pressure cookers, Energy-efficient refrigerators, CFLs, etc.
Hence, clean technologies are those technologies that are both eco-friendly and eco-efficient. Some examples for those are CFLs, Solar heating devices, energy-efficient refrigerators etc.
