Anything, I mean anything that is use to "show off" is a "status symbol". Whether it is dress, car, house, UPS, Battery, Generator or the animal for "qurbani". And guess what, Islam doesn't like it. But hey, who cares for Islam, if mullahs tell us it's okay then it's okay.
Ever heard that a mullah openly said not to wear expensive dress to show off, or do not show off your car, house, UPS/Generator. And the biggest of all, did ever a mullah said "do not use the animal you purchased qurbani to show off your wealth". Instead they are very proud to say "My kids are walking the animal in street. They love this animal. It is to increase the love between child and animal. blah blah blah". Not even once, he said "this is wrong and this is total show off and haram in Islam".
And these are my own personal experiences. I and few other people, we bought a good UPS system for mosque. After couple of months, the mullah told me with chest high "I have put more lights, especially on roof, to tell other people that we have UPS and people can come to our mosque and they don't need to go to other mosques where they have no UPS". I was thinking, "f*** you mullha, I paid for this UPS and you are showing off just to gather more people and making it as a business". Of course, I didn't said this to him. But if that's the mentality of people then yes, UPS/Generator is a status symbol.
Beside that, I don't need extra electricity. In fact, I go the opposite side. I have replaced all the light bulbs in my homes and office with 8 watts, 5 watts and where it is needed with 11 watts (very few). It is so fun to see my home's bill in the first slab only. I personally use laptop, cellphone and an "emergency light" (LED, small one). But hey that's me. I am okay whether it's hot or not. I do curse WAPDA and government. But I don't see the reason to light up every light (especially in load-shedding) in home with UPS/Generator to inform the whole colony that "people with UPS/generator are richer than those who don't have it".
But hey, I know people who especially turn on gates light to tell everybody that "we have UPS/generator". You can't change people. But you can change yourself.
