Actually it's renewable, because the trees that produce the wood can grow again - you can grow more trees.
Wood is made into an energy source through a process called combustion, where it is burned to release heat energy. The heat can then be used to generate electricity or heat buildings. Wood can also be converted into biofuels such as wood pellets or wood chips to be used as a renewable energy source.
wood
People have been burning wood for centuries to provide themselves with heat energy.
Cheap source of energy
The Sun is the ultimate source of all energy on earth.
Wood is considered a renewable energy source because it comes from trees that can be replanted and regrown. As long as trees are harvested in a sustainable manner, wood can be continually replenished.
Carbon
The wood can be burned in a fire.
Wood is the first discovered primary energy source. Some believe that Solar energy (as heat caused by sun light) is the first discovered primary energy source.
No. Solar energy comes from the sun.
