Why is burning wood pellets better than burning wood directly?

Within the last decade wood pellets have been used as an alternative fuel source to fossil fuels. Wood pellets can be transported as a liquid and readily flow via hopper systems. The density of pellets increases the combustion temperature beyond that of simply burning logs.In other words, the calorific value of biomass wood pellets is better, and it is easier to burn fully, which will ultimately save fuel costs.
