Alternative fuels beside gasoline are In light of the reserves available and the dismal projections, it is apparent that alternative energy sources will be required to sustain the civilized societies of the world in the future. The options are indeed few, however, when the massive energy requirements of the industrial world come to be appreciated. Commercial oil shale recovery and the production of a synthetic crude oil have yet to be demonstrated successfully, and serious questions exist as to the competitiveness of production costs and production volumes that can be achieved by these potential new sources.
Although alternative energy sources, such as geothermal energy, solar energy, and nuclear energy, hold much promise, none has proved an economically viable replacement for petroleum products. .
Chemical Reaction that when fuels under go burned process by which atoms or groups of atoms are redistributed, resulting in a change in the molecular composition of substances. An example of a chemical reaction is formation of rust (iron oxide), which is produced when oxygen in the air reacts with iron.
Most scientists agree that if pollution and other environmental deterrents continue at their present rates, the result will be irreversible damage to the ecological cycles and balances in nature upon which all life depends. Scientists warn that fundamental, and perhaps drastic, changes in human behavior will be required to avert an ecological crisis. .
To safeguard the healthful environment that is essential to life, humans must learn that Earth does not have infinite resources. Earth's limited resources must be conserved and, where possible, reused. Furthermore, humans must devise new strategies that mesh environmental progress with economic growth. The future growth of developing nations depends upon the development of sustainable conservation methods that protect the environment while also meeting the basic needs of citizens.
