Answer 1

The correct option is D All of the above

Conservation of energy is of great concern nowadays. Light is also a form of energy which should not be wasted. The best way to conserve the light energy are as follows.

(i) Turn off the lights when not in use.

(ii) De-dust lighting fixtures to maintain illumination.

(iii) LED Lamps should be used instead of conventional incandescent bulbs. For example, a 16w LED bulb can be as bright as 150w halogen lamp. LED lamp consumes 1/3rd of CFL energy and 1/30th energy of incandescent bulbs.

(iv) Conventional regulators should be replaced with electronic regulators for ceiling fans.

(v) Install exhaust fans at a higher elevation than ceiling fans. In diary/poultry industry usage of multi fan axial fans leads to low energy consumption with low noise levels etc.

Thus, the correct option is D.
