Assessment of Carbon Footprint Associated with Electricity Consumption at Deen Dayal Upadhyaya Gorakhpur University, India
This study assesses the carbon footprint of electricity consumption at Deen Dayal Upadhyaya Gorakhpur University from 2019 to 2024, revealing significant seasonal and pandemic-driven fluctuations in emissions while highlighting the critical role of solar energy and energy management strategies in achieving sustainable campus development.

Imagine the Deen Dayal Upadhyaya Gorakhpur University (DDUGU) as a giant, bustling house with thousands of rooms, labs, and dormitories. Just like any big house, it needs electricity to keep the lights on, the computers running, and the air conditioners humming. But here's the catch: in India, most of that electricity comes from burning coal and other fossil fuels. When you burn that fuel, it releases invisible "smoke" into the sky—specifically, greenhouse gases like carbon dioxide. This "smoke" is what the paper calls the Carbon Footprint.
Think of the university's carbon footprint as a backpack. Every time the university uses electricity, it adds a heavy brick to that backpack. The more electricity used, the heavier the backpack gets, making it harder for the planet to breathe.
The Story of the Backpack (2019–2024)
The researchers looked at the university's backpack over six years to see how heavy it got and why. Here is what they found, broken down into simple stories:
1. The "Summer Heat" Effect
Just like you feel the need to turn on the fan or AC when it's scorching outside, the university's electricity usage spikes in the summer (May and June).
- The Analogy: Imagine the university is a car. In the winter, it idles gently. In the summer, it's revving its engine hard to run the air conditioning.
- The Result: The backpack got heaviest during these hot months because the university was using the most electricity to stay cool.
2. The "Silent Library" Years (2020–2021)
Then, the world stopped. The pandemic hit, and the university had to lock its doors. Students and teachers went home, and classes moved online.
- The Analogy: It was like the giant house suddenly became a ghost town. The lights were off, the labs were quiet, and the ACs were sleeping.
- The Result: The backpack got much lighter! Because so much less electricity was used, the university produced far less "smoke." The researchers saw a massive drop in emissions during these years.
3. The "Busy Campus" Return (2023–2024)
When the pandemic restrictions lifted, everyone came back. The campus filled up again, and normal life resumed.
- The Analogy: The ghost town turned back into a bustling city. The lights flickered on, the computers booted up, and the air conditioners roared back to life.
- The Result: The backpack got heavy again. In fact, by 2024, the university was using even more electricity than before the pandemic, making the backpack heavier than ever.
The Solar "Superhero"
The university isn't just sitting there taking the heavy load; it has a superhero on its roof: Solar Panels.
- The Analogy: Think of the solar panels as a personal generator that creates its own "clean" electricity. When the sun shines, this generator kicks in and takes some of the weight off the university's backpack.
- How it worked: In some months, the solar panels were so good that they actually produced more electricity than the university needed. In those moments, the university didn't just stop adding weight to the backpack; it actually started removing weight. The researchers even saw "negative" numbers, meaning the solar power was doing more than just covering the university's needs—it was helping the grid.
However, the superhero had a bad day in 2023.
The paper notes that in 2023, the solar panels didn't produce as much power as they usually did (perhaps due to maintenance issues or cloudy weather).
- The Result: Because the superhero was tired, the university had to rely more on the "dirty" grid electricity again. This made the backpack heavier that year, even though the university was trying to be green.
The Big Takeaway
The paper concludes that the university's "backpack" (carbon footprint) is directly tied to how much electricity it uses and where that electricity comes from.
- When the campus is busy: The backpack gets heavy.
- When the sun shines and panels work: The backpack gets lighter.
- When the panels fail or the sun is weak: The backpack gets heavy again.
The researchers say that to keep the backpack light in the future, the university needs to keep its solar panels working perfectly, use less energy when possible (like turning off lights), and maybe find more ways to generate clean power. They aren't promising to solve climate change for the whole world, but they are showing that for this specific university, managing electricity is the key to carrying a lighter load.
