The exact contribution alternative energy sources make to the total primary energy used around the world is not known. Conservative estimates place their share at 3–4%, but some energy experts dispute these figures. Amory Lovins has argued that the statistics collected are based primarily on large electric utilities and the regions they serve. They fail to account for areas remote from major power grids, which are more likely to use solar energy, wind energy,or other sources. When these areas...
