Practical exercise
Install one solar rechargeable bulb in your house
Pakistan loadshedding is back in many cities; rural areas never lost it. A solar rechargeable bulb costs 700 to 2,500 rupees, charges in daylight on a small panel, and gives 4 to 8 hours of light at night with zero electricity bill and zero noise. Today you buy one, install it in the room that suffers most when WAPDA cuts, and prove with a photo that the room is lit during loadshedding.
Now try it
Install one solar rechargeable bulb in your house
Stretch
If the first bulb works well after two weeks, plan a second bulb in the next loadshedding-critical room (kitchen, bathroom, study). Make a simple two row table comparing nightly runtime of bulb 1 versus bulb 2 over a week.

The receipt of the bulb purchase, a photograph of the bulb installed, a photograph of the room lit during a real loadshedding (with clock visible), and a short note with measured hours of runtime and estimated rupee saving per year.
