Is Granite renewable or nonrenewable?

Is wood energy cheap?
However, in comparison with many other energy resources, the energy density of raw wood is relatively low. … Greater use of residues and wastes is a potential source of relatively cheap biomass for energy.
Is oil a source of energy?
Petroleum has historically been the largest major energy source for total annual U.S. energy consumption. We use petroleum products to propel vehicles, to heat buildings, and to produce electricity.
