Hydrogen: A Reliable Source of Energy for Our Children
“Society cannot exist without energy” (Nakaya 8). Energy is used
to provide heat, to cool and light their homes, to refrigerate and cook their food, and to
fuel transportation. It also provides power for telecommunications, commercial and
industrial activity (8). Andrea Nakaya states that, “Humans are virtually helpless
without a reliable energy source, such as, the element Hydrogen” (8). In addition, many
scientists argue that there is a major problem with our reliance on “fossil fuels” and that
we must start looking for other resources (Nakaya 11). This is why the use of hydrogen
as an alternative fuel source the use of hydrogen as an alternative fuel source we can
reduce if not eliminate our toll on the environment from chlorofluorocarbons (CFCs),
have access to limitless energy, and possess a more powerful and efficient transportation
fleet.
Andrea Nakaya states, “History shows that in the past, society has shifted from
one energy source to another” (11). Throughout history, the United States’ many energy
transitions show that as our technology advances, we require more efficient energy
sources (11-12). Such as our switch from “solar energy” and “wind power” in
“early societies”, “to burning wood, charcoal, and agricultural residues.” (12)
Throughout the 1800s coal became the United States’ “main energy source”, and “after
******** 2
World War II, petroleum” (12) became the United States’ new energy source. In addition,
Andrea Nakaya states, “Many people believe the United States relies too much on fossil
fuels and is not doing enough to pursue alternative energy sources” (15). In addition, the
use of petroleum is taking a major financial, and environmental toll on the United States.
In the present day, our technologies are advancing; we need an even more resourceful
basis for energy. As a result many scientist are proposing a new transition to the use of
Hydrogen as a main fuel source.
Hydrogen is considered a clean fuel that has a minimum impact on the
environment nearly eliminating the levels of carbon dioxide and other greenhouse gas
emissions. A chlorofluorocarbon (CFC), is an organic compound which derives from
methane and ethane (a product of the burning of fossil fuels), that contains carbon,
chlorine, and fluorine. The atmospheric impacts of CFCs are not limited to an ozone
reducer. This compound is also a greenhouse gas, with a much higher potential to
enhance the greenhouse effect than CO2. It is safe to manufacture, reliable and
environmentally friendly. The huge advantage that hydrogen has over other fuels is that
as a fuel it is non-polluting, when you combust hydrogen the only bi-product is water.
David Garman states, “Hydrogen can fuel ultra-clean internal combustion engine, which
would reduce auto emissions by more than 99 percent” (Hydrogen-Powered Vehicles…)
(See Table 1).

Table 1: The bar graph represents the grams of CO2 per person, released through
gasoline use than through the use of hydrogen. Also, as CO2 is the leading cause of
global warming this graph illustrates how much of that CO2 escapes into the air every
year.
It has been scientifically proven that the more industrialized a country is the
higher a country’s nation energy consumption level. According to Anne Mucsulak, “The
International Energy Association (IEA) has estimated that developed countries use about
3.4 million tons (3.1 million metric tons) of energy sources (on an energy-equivalent
basis with oil), but developing countries use only 1.7 million tons (1.5 million metric
tons)” (4). It is common knowledge that oil is a non-renewable source of energy. That
