Since time immemorial, we have seen a change in the types of powers used. As early as the 1200s, territory swapped wood to coal as deforestation appeared in the local area. 300 years subsequently, societies then depended on petroleum after depleting the supply of whale oil used to fuel lights. In the early 1900s, corn-based ethanol oil provided the need for power. Seismic explosives are normally used to acquire these natural sources of energy.
