The world is changing each and every day. In
the course of the 20th century, the human population has increased
from 1.6 billion to 6.1 billion people. The world’s population has multiplied
more rapidly now than ever before. The growth of human population is a major
contributor to global warming, since humans use natural resources to power
their entire lifestyle. The Earth’s climate has also changed throughout
history. The evidence for the rapid climate changes occurring today are the
rise in global temperature, the warming oceans, the shrinking ice sheets, the
glacial retreat, the decreased snow cover, the rise in sea level, the extreme
events, and the ocean acidification. Today’s climate change has already had visible
effects on the environment in where glaciers are shrinking faster, ice on
rivers and lakes are breaking up earlier, and trees are flowering much sooner. Everything
around us is going to keep changing unless we do something about it.
We as Americans use many different types
of energy. Most of the nation’s energy production is 33% of natural gas, 28% of
petroleum, 17% of coal, 12% of renewable energy, and 10% of nuclear electric
power. The energy consumption for the five sectors are 39% for electric power,
29% for transportation, 22% for industrial, 6% for residential, and 4% for commercial.
There are a few green energy products that
I am aware of and personally use myself. One of them is LED lightbulbs. LED
lightbulbs have shown to be more effective and long-lasting than incandescent lightbulbs.
While the costs of LED lightbulbs are a little higher than incandescent lightbulbs,
the energy savings of LED lighting in the long run is much higher. There are
many differences between LED lightbulbs and incandescent lightbulbs. The first
difference is brightness. LED lightbulbs are much more efficient at utilizing
wattage to produce lumens. A LED lightbulb requires less watts than the traditional
incandescent lightbulbs. The second difference is efficiency. Producing the
same level of brightness, an LED lightbulb has an average lifespan of 50,000
running hours where as an incandescent light bulb only has a lifespan of 1,200
running hours. The efficiency of LED lightbulbs leads to considerable energy
savings. The last and third difference is the environmental impact. LED lightbulbs
are an eco-friendlier lighting solution than incandescent lightbulbs. A
household using LED lightbulbs instead of incandescent lightbulbs can
drastically reduce their carbon footprint.
There are many things that we as
individuals can do to contribute to the solution of the global warming issue. There
are lots of simple and easy ways in which we can make the planet a better place.
One, is to drive less or carpool because we are not only saving on gas but
helping reduce global warming. Two, is to reduce the waste of water which can
reduce carbon pollution and can be done by taking shorter showers or turning
off the water while brushing your teeth. Three, is to change lightbulbs and can
be done by buying LED lightbulbs which use up to 80 percent less energy than
regular lightbulbs. Four, is to unplug your outlets and can be done by
unplugging devices and electronics when they are not in use because even when
they are not charging they are still using energy. At the end of the day, our
biggest assest is our voice and when we talk about global warming and bring
awareness to it the more people are willing to make a change. We must make a
difference now before it is too late.
