For people who have improved an older home, which energy-efficiency project made the first meaningful difference?

I am curious how you would rank air sealing and weatherstripping, attic insulation, thermostat upgrades, window improvements, and HVAC changes. Looking back, what would you prioritise first, and what did not justify the cost or effort?

I am interested in practical, low-cost ways people have reduced electricity use at home. Which changes made a noticeable difference for you, and which common tips did not seem worth the effort?

I would especially appreciate examples involving heating or cooling habits, appliances, lighting, and standby power.
