Reduce the use of items like paper towels, plastic wraps, bottled water, and newspaper.
Reuse. Items like Tupperware containers, metal water bottles, and grocery bags can be reused for multiple times.
Recycle. Items like glass bottles, plastic can, and aluminium cans can be collected and being reprocessed into new containers.

The easiest example here is a computer/laptop... e.g. when the CD-ROM is spinning when you are perhaps playing a movie, the kinetic energy causes friction, which results in heat. All computers need a fan to prevent them over-heating for this very reason. Therefore heat is lost and energy is wasted.
Another example is a lightbulb. When a light is switched on and left for a long time, the current flowing through the filament (the thin bit of wire in the bulb) causes heating (due to electron-ion collisions but you may not need to know that) so energy is wasted as thermal energy instead of light energy.
These are just a few examples but other ones you could use are tv screens, kettles, toasters, etc :)
