Solar and Wind
There are 2 ways, 1.obtaining chemical energy 2.obtaining light energy
At least 2 ways, Sound (kinetic), heat and sometimes light.
Wave action and tidal currents are being utilized today to produce electrical energy.
Increasing the speed of an object or increasing its mass are two ways to increase its kinetic energy. Additionally, changing the direction of motion can also result in an increase in kinetic energy.
Energy can be transferred through conduction, which is the direct transfer of heat through a material, and through radiation, which is the transfer of energy through electromagnetic waves.

Heating is a major application.
Recycling reduce the energy of processing raw material and made into the product, it also reduce the energy required for the waste management process.
Two of the biggest areas of energy study in high school physics is kinetic energy (energy of an object that is moving) and potential energy (the potential of an object to do work - such as being being at the top of an inclined plane). However there are MANY other forms of energy.
1ELECTRICITY A.operate machine B.communication C.fuel 2.TRANSFORTATION 3.DISINFECTS
they use it for 1.transportation 2.recreation 3.hydroelectric energy
In the most general terms, that would be: (1) Find new energy sources or make better use of the existing energy sources; and (2) Use less energy.
