Main type is light energy. Also some heat is produced
Some elements produce light because of a change in energy state levels. The color of the light is determined by the difference in energy between the excited state and the ground state.
The rubber band doesn't produce energy.It stores the energy that you put into it when you stretch it.The harder a rubber band it is to stretch some distance, the more energy it's storing,and the more energy it'll deliver when you release it.

All bulbs produce heat energy and light energy ,even the CFL (Compact Fluorescent Lamp) there is also some heat energy associated with them.
your question is not phrased very clearly=what exactly do you want to know? No, they consume energy (calories) for their activities. Through metabolic activity they might produce some heat but in terms of keeping the body warm, this is achieved by the muscles.
The most famous example is fire. It can move, breathe, multiply, grow, consume and produce energy....etc.
Caffeine of some sort
This depends on what microorganism. Some microorganisms, like microscopic plants and some bacteria, are autotrophic (specifically phototrophic), meaning they create their own energy using (mainly) water and sunlight. Other microorganisms, like some bacteria and fungi, are heterotrophic, meaining they consume other organisms to get their energy.
no they get energy from the food they consume. we use sugar that is pretty much present in everything and the oxygen we breathe in, and our cells react these together to produce energy. of course, this is aerobic respiration. some organisms of capable of respiring anaerobically and therefore have no use for oxygen at all
Some do when burned
All of them produce some energy. Even Monaco, Nauru, and Tuvalu have some combination of solar panels and/or wind mills.
Mainly they produce ATP.Also produce some enzymes,proteins etc
To produce energy for the website 4chan.org
They produce chlorophyl in order to make energy through photosynthesis.

Generally, no; most electronic devices only consume between 5% and 20% of their normal operating power when in standby. Some devices like copiers or laser printers only consume a couple of percent of their normal power because printers consume a LOT of energy in normal use to fuse the toner to the paper.
