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 wood is transforming chemical energy to light and heat energy.
It is the breaking of chemical bonds, and therefore is releasing chemical energy.
Pollution!
Stored Chemical energy being converted to, and released as Heat energy.
A burning candle produces thermal energy and light.
Wood is a fuel as it can provide energy by burning. But, it is not formed by fossils and hence not called a fossil fuel.
When wood burns, chemical energy is transformed into heat
You need to burn a variety of hardwoods. You need a combination of fast burning hardwoods, such as Maple and Birch, along with slower, hotter burning woods such as Oak and Ash. The fast burning woods keep the hotter burning woods burning. Some other great woods for the stove are Apple, Cherry, Black Locust, Honey Locust, and Hickory. Elm and Sycamore will also work, but don't give off as much heat as the ones I have mentioned.
Thermal energy........
Energy cannot be created. (Or destroyed) Burning changes the chemical energy of the wood to heat energy and light energy.
This kind of energy is called renewable energy.

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.
By burning it. The heat it lets off will be energy.
People have been burning wood for centuries to provide themselves with heat energy.
