Benefits of Solar Energy on Global Warming

Hannah Smick: Very very good! Great wording, great pictures, and very nice information!

What is solar energy?
Solar energy is energy derived from the sun in the form of solar radiation. (dictionary.com)


How does solar energy work?

As you can see from the above picture, solar panels are installed on your roof. The panels catch the sunlight and convert it to DC power. DC stands for Direct Current. Direct current is an electric current that flows in one direction only (thefreedictionary.com). Then, the DC is converted into AC electricity. AC electricity stands for alternating current electricity. Alternating current electricity is an electric current that reverses direction in a circuit at regular intervals (thefreedictionary.com). Along with the solar panels, the installers put a meter on the side of your house that tells you how much electricity you are using. According to the picture, the meter also tells you that the panels on your roof is sending power back into the grid when it is spinning counter-clockwise.

What are the benefits?
Solar energy is affordable!
By 2015, solar energy is expected to be cost-competitive with electricity generated from coal (greenliving.nationalgeographic.com).

It is energy efficient!
Solar energy is renewable, as well as sustainable. This allows us to be able to use it over and over again without running out of it because the energy is coming from the sun. Having solar panels would allow us to be independent when it comes to electricity. Meaning, we wouldn't need to rely on utility companies to supply our power. This means that if a thunderstorm hits your area, or the area in which your utility company exists, your power won't go out. (Assuming that you have enough energy stored, that is.)

Creates jobs!
In 2007, a majority of the 89,000 jobs that were created, were created for people to creating, distributing, and storing clean energy in the United States (greenliving.nationalgeographic.com).
The American Council for an Energy-Efficient Economy has estimated that around 1.1 million jobs could be created by solar energy companies within the next ten years. The New Jersey Public Interest Group said that 25,390 jobs could be created with a payroll of $364 million by the year 2014 in only about 10% of mid-Atlantic homes used solar energy( That could really help our economy-Jenny Falatko) (sustainablebusiness.com).

How does it relate to Global Warming?
We can use sunlight over and over again because the sun comes out everyday. For the days when it's cloudy, the panels on the roof of your house have energy stored up so you can still use the electronics and such in your house. Solar energy doesn't need coal or fossil fuels to work, which is the point. So, if everyone had solar panels, we would greatly cut down on the use of those two things. If we don't burn coal or fossil fuels, we won't emit as much air-polluting smoke into the air. The smoke is part of the problem because it depletes the amount of ozone layer that we still have left.
The ozone layer is a gas that occurs naturally in our atmosphere. The ozone layer is the part of our atmosphere that keeps ultraviolet rays from the sun from reaching us (research.noaa.gov).
The ozone layer also does not produce greenhouse gases (greenliving.lovetoknow.com). Greenhouse gases are any of the atmospheric gases that contribute to the greenhouse effect (thefreedictionary.com). The greenhouse effect is when the earth's atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane that allow incoming sunlight to pass through but absorb heat and radiated back form the earth's surface (thefreedictionary.com).
