What does it actually mean living with 4kW a day?

Living with 4kW per day in 2023

To start this challenge in the best way possible, I thought it was essential to understand what it actually means to live with 4kW of electricity per day.

So today, I decided to try to figure out how much I actually consume in a “typical day” to understand if and how I can reduce my consumption and perhaps see if any good practices in my routine can actually be eco-friendly.🙈🌞

This is what I used electricity for today:

  • 1 coffee made with the coffee machine: 0.07 kWh
  • 1 cup of milk heated in the microwave at 800 degrees for 1 minute: 0.013 kWh
  • Lunch heated in the microwave for 2 minutes at uni: 0.026 kWh
  • Charged my iPad for an hour: 0.02kWh
  • Charged my computer for two hours: 0.122 kWh
  • Dried my hair with the hairdryer: 0.375 kWh
  • Styled my hair with the hair curler: 0.013 kWh
  • Had dinner with my family. My mom cooked a pasta dish for 5 people (with tomatoes and tuna, so no cooking for that): 0.07 kWh
  • Family dishwasher: 0.4 kWh
  • Charged my phone for 1 hour: 0.01 kWh
  • Charge my portable charger for 1 hour: 0.01 kWh
  • Took a hot shower: 1.125 kWh
  • Total: 2,254 KWh

Other things that I can’t measure

  • I used public transportation, so I can’t measure the energy consumption
  • Lights/heating at home
  • University energy usage

In conclusion, without accounting for the energy consumption related to household appliances, transportation, and university activities, I have come to realize that I actually consume quite a lot of electricity every day for my normal activities, even if I often don’t even think about it. This includes everything from the morning cup of coffee heated in the microwave to the hours during which I leave chargers plugged in.

Consequently, I have started to reflect on how I can effectively, in my own small way, reduce the amount of energy I use for my daily activities…
