Heat's produced by many objects, like heaters, lights, engined, the sun, etc. All of that comes from particles rubbing together, which creates friction, which creates heat. I'm not sure how the process starts, but when particles get hot, they [move around] more, which creates the heat. I not 100% about this, so please correct me if I'm wrong :)
Some examples of machines that produce heat when being used include ovens, stoves, heaters, furnaces, computers, and automobiles. These machines generate heat as a byproduct of their operation due to friction, electrical resistance, or combustion processes.
Coal is a fossil fuel,that is being used to produce electricity and heat.
An incandescent bulb produces heat when turned on, with about 90 of its energy being emitted as heat and only 10 as light.
An example of electricity that can produce heat and light is incandescent light bulbs. These bulbs use electricity to heat a filament inside, causing it to give off light and heat. The filament emits light as a result of being heated to a high temperature.
Higher heat plus shorter baking time can produce puffier, softer, chewier cookies (all other things being equal). Lower heat plus longer baking time can produce crisper, flatter cookies. The cookies will continue to cook from their internal heat for a short while after being removed from the oven.
Heaters use electricity to produce heat by resistance.
Filipino is an inhabitant of the Philippines , and they produce heat through body heat , they dont produce light :S
No, a jacket does not produce heat by itself. The warmth that you may feel while wearing a jacket comes from your body heat being trapped by the insulation of the jacket. The energy source is the heat generated by your body.
Glow sticks do not produce heat as they operate through a chemical reaction, rather than a heat-producing process like combustion. The reaction involves a chemical compound inside the stick being mixed with a separate chemical compound, which produces light without generating heat.
Sunlight and photovoltaic (PV) panels (solar panels) produce electricity.Sunlight and a solar thermal collector produce heat by capturing solar radiation. The heat is then used to heat water, heat air, cook food, or heat a fluid that drives a turbine which creates electricity.Photoelectrochemical cells or PECs are solar cells that produce electrical energy or hydrogen in a process similar to the electrolysis of water.

Through metals which are good conductors of heat: often these are compounds of metals which can ( due to the tight particles producing energy) heat to a desired temperature, copper being an example of this.
