I don't think you're going to get people to collectively reduce energy usage unless there is a direct incentive to do so, e.g. the price spikes you yourself mention.

The best way to solve this is probably through regulation. In the case of leaving the lights on, this has mostly been "solved" by banning incandescent light bulbs which use ~10x as much energy as the LED light bulbs that are in use everywhere now. I think this is as good as it's gonna get right now with light bulbs. Energy usage of household appliances can be solved in the same way (not sure if it is, I just know about the labeling) and—at least in my country—heating consumption is being solved by increasing insulation requirements pretty hard.

Even LED have more efficient designs, Philips makes the Dubai Lamp specifically for Dubai but you cannot buy them outside of Dubai.

The efficiency difference is very small; the main advantage of the Dubai Lamp is that it lasts longer.
