If It’s Sunny You’ll Save Money

Considering the fact that this blog is online, I am assuming that you are using a computer, smartphone or tablet to view this page. Now, I ask you to take a moment to reflect and think about how long you have been on this computer and how much electricity you have been using during the duration of this time. The average American spends about 5 hours a day on digital devices ( figure 1). Annually, that is a total of 1825 hours on digital media. Think about this, and think about how much it costs the average American to power their digital devices.  This means that the average American can spend up to 600 dollars just on electrical bills for their computer. However, what if there was a way to power your computer just using the environment around you?

Using solar power is all the rage as individuals are discovering that they can cut back on electrical bills by using energy from the sun. Solar panels allow us to use , solar energy (a type of solar power) which comes from the sun. In doing so, solar energy can be converted into electrical energy, which can then be used to power things such as a computer and other devices which need electricity to work (figure 2).  Solar energy allows one to power devices with low cost renewable energy and using solar energy to power devices is a fairly simple process.

Companies such as Samsung and SOL have developed laptops that run solely on the energy from the sun. The computer developed by Samsung is powered by a solar panel embedded in the lid. In order to function the computer needs approximately 2 hours of sunlight to get 1 hour of working battery life. When fully charged, the computer battery can last up to 14 hours straight. This computer costs about $350 US dollars. Similarly the company SOL (known for developing devices using solar energy) developed a laptop which uses solar energy as well. This laptop is more efficient than the Samsung, as it is equipped with a detachable solar panel which can obtain 10 hours of battery life from just 2 hours of sun exposure (figure 3). This Laptop costs the exact same amount as the samsung computer, costing about $350 US dollars. By purchasing either of these laptops one would be purchasing a laptop $400 dollars less than the average computer and it is powered free of charge due to its solar panel technology.

Converting to solar energy is 100% cost efficient and can end up saving you thousands of dollars (figure 4). Personally, I think that everyone should convert to solar power as it is a natural never ending resources that the earth has given us. Although one must pay for the initial cost of installing solar panels, in the long run solar panels save you up to 7 thousand dollars (figure 4). By using solar energy one can cut back on electrical bills and it makes for a more cost efficient lifestyle. Developing technology that allows computers to run on solar panels is truly revolutionary and I think that there is no better place to start converting people to using solar energy, than the devices we use on a day to day basis.

One thought on “If It’s Sunny You’ll Save Money

  1. Sammie, I really like that you called everyone reading this blog out on our electronic uses and then provided alternatives that are more energy and cost efficient. Did you find anything in your research about the efficiency of solar energy, though? 28 hours seems like a long time to leave your computer in the sun for only 14 hours of battery life. Most of the solar technology we have only has around 15% efficiency (http://pureenergies.com/us/how-solar-works/solar-panel-efficiency/). I’m interested to see if we will be able to improve this in the future, because solar power has the potential for almost 95% efficiency. Hopefully we’ll get there so we can power even more things from the sun!
