In an Alternating Current system, the electrons oscillates back and forth. In Power Inverters (where you convert DC to 110 volts AC), the output is just a sine wave.. meaning the electrons don't really oscillate back and forth but only vary in intensity in time. What is the effect of either on the load? Are their Power Inverters where the electrons can also oscillates back and forth like in the AC?

I think for your purposes you can assume there is no real difference between the AC you get from a wall socket and that produced by a mains inverter. The electrons behave similarly for both.
Some mains inverters don't produce very pure (smooth) sine waves and that can cause problems for sensitive equipment like radios.
What do you mean the electrons behave the same. In the Alternating Current. It goes forward and backward in time, while in the Inverter, it goes forward only. Isn't it.
The drift velocity of the electrons are slow. In AC, how can it have enough time to go forward and backward.

No a Mains Inveter (if thats what you mean) is a device that converts 12V DC to 110V AC to provide power for tools etc when you don't have a wall socket handy (eg in the middle of a field). In other words it's output is similar to what you get from a wall socket.
Because they don't move very far. They mostly just sit there and vibrate. It's like the air in a room - it doesn't move much when you play the radio. The sound waves and their energy go through the air but the air molecules just vibrate.
My understanding is that a typical DC to AC power inverter produces something more like a square wave than a sine wave. In fact, I have an inverter and the picture they show of the output is just like that except there are little gaps "between the squares." You can buy more expensive ones that produce a shaped output that looks more like a sine wave. But in addition to costing more, you lose more power in the conversion.
Most devices - e.g. computers and light bulbs - respond perfectly well to the inverter. But some motors generate more heat because of the shape of the wave and you have to be careful.
