Mills were powered mostly by wind or flowing water.
Wind energy is derived from wind mills. These wind mills are powered by the wind and capture it's energy when it blows.
It is powered by electrical energy which is converted to heat and motion, as well as some wasted as noise and vibration.
The chemical energy in the battery is converted into electrical energy to power up the phone.
Photosynthesis is powered by light energy from the sun; and sunlight is a type of energy called electromagnetic energy or radiation. Electromagnetic energy travels in space as rhythmic waves.

19th century factories were often powered by mills that used the running water of a river. This is part of the reason many industrial towns were built on rivers. They were also powered by coal.

Water Energy: Water is an energy source that may be used to power mills. In fact, many mills were water-powered in history. Some, but not as many, mills are water powered today. Keeping the example of water-powered mills, the water mill would have to be in a river. If during a drought (per say) the water level of the river dried up or diminished, falling rain would renew it. Of course, water is recycled through the water cycle, so water never diminishes. The form in which the water is in just changes its state of matter.
They produce mechanical energy which then creates electricity

Talking is powered by chemical energy derived from the food you've eaten.
It changes mechanical energy into electrical energy. Hope that helps.
