Energy Crisis Interrelated to Global Warming. Photovoltaic Cell – A Possible

The world’s energy crisis has worsened in recent years, as oil prices dramatically
increased due to the limited amount of available oil. Global warming is considered as a byproduct
of energy crisis, because as oil continues to burn in the refining process, CO2 is
constantly emitted to the atmosphere at a fast rate and in heavy concentrations, which in turn,
worsens the global warming situation. Photovoltaic cell technology converts sunlight into direct
current electricity. This source can be a possible solution to solve the energy crisis as well as the
global warming issue.

Energy crisis has remained a top concern in the world today. Fossil fuels, the most widely
used energy source in the U.S. and in the world, is rapidly being depleted due to the fast
consumption rate. Since we are highly depended on oil for transportation, cooking, and
communication in our daily lives, the oil storage is starting to run out and eventually it will be all
gone. Petroleum oil is always considered as a cheap energy source; however, the price of oil per
barrel and per gallon has gone up significantly worldwide. The price of oil has already passed
$60 per barrel, due to the energy crisis and oil shortages (Crude Oil Futures Prices – NYMEX,
2005). The increased oil prices and the limited energy resources will have a great impact to the
global economy where stock prices fall, unemployment rates increase, economic recession and
inflation can occur. Burning fossil fuels are not only causing the existing energy crisis in the
world but are leading to global warming as well. Due to the excessive burning of fossil fuels, the
carbon dioxide concentration has been rising significantly since the industrial revolution
(William, Alhajji 2003). One of the possible solutions to solve these problems is the replacement
of renewable energy, solar energy, which converts sun energy directly to usable energy such as
electricity. This will possibly slow down the process of energy crisis and global warming.

Results and Discussion-
Almost everything in our daily lives depends on oil as a major energy source,
automobiles, freeways, commutes, air travel, food and heater/air conditioning. Since the
production of oil is considered cheap and convenient in economic terms, people rarely consider
alternative sources of energy. Until recently, the energy crisis has worsened. This is indicated by
the rising of oil prices. The world, especially the U.S. is highly depending on the Middle Eastern
oil because oil productions in other places are constantly declining. Not only city residents are
dependent on oil, but also the farmers. Farmer represents 2% of the American population, but
they can produce enough food for the rest of the 98% of the population due to the help from the
oil-powered machineries. It is estimated that it takes approximately one...

With this shortage of trees the air is unable to be cleaned and an overabundance of carbon dioxide
