Oil-based economy refers to the world's dependency on petroleum, natural gas and coal for energy. Electricity, diesel fuel, gasoline and kerosene are only some of the commodities that are provided by oil. However, there are negative effects of the processing to the environment. Combustion of oil by cars yield sulfur oxides, nitric oxides and carbon dioxide that participate in ozone depletion and global warming. Therefore, the more-developed nations are working on better technologies to harness renewable energy for sustainability. These energy refer to solar, hydropower, wind, and tidal resources. As of now, there are problems on the cost of developing and perfecting these technologies to maximize the energy source. Unfortunately, if the world shifts to the clean energy-economy, the less developed countries would have to catch up a great deal. These equipment are quite expensive, so for a time-being, only the more developed countries would participate and earn from it.

Lincoln's main concern in his Second Inaugural Address was peace.
Lincoln sees the War as the divine retribution for the United State's sin of slavery. He states that both sides wanted to avoid war but one, the South, for its economical reasons, the ownership of slaves, wanted to tear the nation asunder, and the other went to war because they could not let the nation perish, the North. Lincoln wants that people forget their grudges and to together heal the wounded nation. To forget retribution and "with malice toward none, with charity for all" rebuild the torn nation.
