## Step 1<br />The question is asking for the advantages of coal over wood as an energy source and the major reasons for using coal for energy. <br /><br />## Step 2<br />Coal has several advantages over wood as an energy source. Firstly, coal is denser than wood, which means it can produce more energy per unit volume. This makes it a more efficient energy source. Secondly, coal is easier to store and transport due to its solid state. This makes it a more convenient energy source. Lastly, coal is abundant and can be found in many parts of the world, making it a readily available energy source.<br /><br />## Step 3<br />The major reasons for using coal for energy are its high energy content and availability. Coal is a dense, carbon-rich material that can produce a large amount of energy when burned. This makes it a highly efficient energy source. Additionally, coal is abundant and can be found in many parts of the world, making it a readily available energy source.
