CT: There are many reasons the world is looking toward alternative energy sources in an effort to reduce pollutants and greenhouse gases. Alternative, or renewable energy, sources show significant promise in helping to reduce the amount of toxins that are by-products of energy use and help preserve many of the natural resources that we currently use as sources of energy.

N: 1. alternative (adj): 1580s, “offering one or the other of two,” from Medieval Latin alternativus, from Latin alternatus, past participle of alternare (see alternate (v.)). Meaning “purporting to be a superior choice to what is in general use” was current by 1970 (earliest reference is to the media). Alternative energy is from 1975. Related: Alternatively.
energy (n): 1590s, “force of expression,” from Middle French énergie (16c.), from Late Latin energia, from Greek energeia “activity, action, operation,” from energos “active, working,” from en “at” + ergon “work, that which is wrought; business; action”.
Used by Aristotle with a sense of “actuality, reality, existence” (opposed to “potential”) but this was misunderstood in Late Latin and afterward as “force of expression,” as the power which calls up realistic mental pictures. Broader meaning of “power” in English is first recorded 1660s. Scientific use is from 1807. Energy crisis first attested 1970.
sources (npl): source, mid-14c., “support, base,” from Old French sourse “a rising, beginning, fountainhead of a river or stream” (12c.), fem. noun taken from past participle of sourdre “to rise, spring up,” from Latin surgere “to rise”. Meaning “a first cause” is from late 14c., as is that of “fountain-head of a river.” Meaning “person or written work supplying information or evidence” is by 1777.
2. Alternative energy encompasses all those things that do not consume fossil fuel. They are widely available and environment friendly. They cause little or almost no pollution. There have been several alternative energy projects running in various countries to reduce our dependence on traditional fossil fuels. There are many impressive options that you can take into consideration.
3. Everyday, the world produces carbon dioxide that is released to the earth’s atmosphere and which will still be there in one hundred years time.
This increased content of Carbon Dioxide increases the warmth of our planet and is the main cause of the so called “Global Warming Effect”. One answer to global warming is to replace and retrofit current technologies with alternatives that have comparable or better performance, but do not emit carbon dioxide.
We call this Alternate energy.
By 2050, one-third of the world’s energy will need to come from solar, wind, and other renewable resources. Who says? British Petroleum and Royal Dutch Shell, two of the world’s largest oil companies. Climate change, population growth, and fossil fuel depletion mean that renewables will need to play a bigger role in the future than they do today.
Alternative energy refers to energy sources that have no undesired consequences such for example fossil fuels or nuclear energy. Alternative energy sources are renewable and are thought to be “free” energy sources. They all have lower carbon emissions, compared to conventional energy sources. These include Biomass Energy, Wind Energy, Solar Energy, Geothermal Energy, Hydroelectric Energy sources. Combined with the use of recycling, the use of clean alternative energies such as the home use of solar power systems will help ensure man’s survival into the 21st century and beyond.
