How Can I Politely Remind Senior Staff to Save Energy at Work?

Dear All,

In our office, not every employee switches off the fans, tube lights, and monitors when leaving the office or going for lunch. Even our senior management is included in this behavior. As a junior in our office, it does not seem appropriate to remind senior employees to turn off the fans and tube lights.

Yesterday, I discussed this issue with our CEO, and he suggested that I put up a notice on the board. Can you help me draft a notice using very polite language?

Thanks & Regards,
Vrusha

I am working in ICICI phone banking operations. Can you provide guidelines for my career prospects? I am interested in the software field. Could you suggest courses that would be beneficial for my career prospects? I have a B.Sc. in Computers. Should I pursue my MBA or MCA through distance learning? Is distance learning taken into consideration?
