Electricity consumption of a 48inch TV each evening

This post is going to focus on daily consumption habit and its impacts of household spendings.

Ever thought how much a 48inch TV can consume each evening?
First off, the TV is bought in 2017, a reputable brand with 4 or 5 ticks in energy saving; so it come as a surprise when my recent month's bill dropped as shown in the screenshot below.

We need to exclude the month of January 2019 as that was the month when I signup with Geneco at fixed tariff rate of S$0.1671 per kWh.

My consumption fluctuated between 250kWh in March 19 to peak bar 313 kWh in Feb 19.
Then suddenly happened as we stopped watching TV each evening, we used to watch 4hours per evening non-stop Monday-Sunday. Suddenly the consumption dropped in August 19 from 279kWh in July to 145kWh.

We thought long on the causes of the pattern and concluded it was due to the TV which was rather unexpected as we often attribute high consumption electronics to air conditioning but for TV to consume almost half of electricity was unexpected.

Beyond electricity saving, some other perks that may come with the free up time in the evening that you can engage in other meaningful activities such as:
- Financial market research on PC, this is another surprise as the PC consumption did not consume much electricity than TV.
- Meaningful time with your loved ones such as talking, reading, playing games or basically any time together
- Evening exercise such as stroll walk in the park, jogging, gym etc.
- Sleep earlier say 9pm instead of previous 11pm

Some potential losses from TV:
- Prime time shows, you may miss out on the hot topics of latest episodes though these days MediaCorp generally just stream dramas purchased from other countries esp. Korean drama, so you could just watch streaming if you like
- News, again you could watch of internet or read from news sites which would present you most content in words though I must admit seeing the cut scenes could be more impactful than reading; but then again you could watch it on live internet news steam too..
- Unsure of what to do with extra time, loss of previous routine; I though this would be a happy problem, simply review the meaningful activities or go to sleep early & feel more energised next day.

How do you think about TV? Do you watch prime time TV like 8pm-10pm?
