Energy cannot be created. (Or destroyed)
Burning changes the chemical energy of the wood to heat energy and light energy.

Burning wood is the process of converting chemical energy in the fuel into thermal energy. Heat transfer is the process of moving thermal energy from one object to another. There are different types oh heat transfer including radiation, conduction and convection. Basically, the wood burning is a spontaneous process, theoretically, but in order for the process to become under way something called the activation energy must be overcome, which means that an energy of that magnitude must be applied to the wood to get it burning (oxidising). This usually comes in the form of a spark or a flame from your lighter. So once you apply that activation energy from your lighter, the wood begins to burn, and the burning of the wood itself produces heat to propagate the process. So long as there is oxygen, fuel (such as wood or octane for example) and the initial spark, then you have fire!
Since the "law of conservation of energy" states that energy cannot be created or destroyed, all energy is never really destroyed only changed. Chemical energy is converted into thermal energy by certain chemical reactions, like combustion (when something is burned) or when fat is metabolized into heat for the body for example.

This kind of energy is called renewable energy.

Yes, burning is a chemical change.
Wood is stored energy. The energy from the sun and water and carbon dioxide from the environment has been converted by a plant by photosynthesis into complex starches such as cellulose. These starches can be converted back into energy by various processes, including: * digestion * combustion.
Burning is a chemical change.
Fuels such as oil, wood, coal, and natural gas have energy stored in them. This kind of energy is called chemical process of burning, the energy is released in the form of heat.
