Solar Energy in the World

(SolarPower.com)

Solar power is created when sunlight hits solar panels and these solar panels convert the sunlight into usable energy. (EDF Energy) Solar power makes sense to eliminate the use of harmful materials to power the country, but as with all innovations in energy, the cost is throwing off some investors. For others, they see the benefits in solar energy for consumers and themselves.

Google is one of these companies. Google has agreed to invest $103 million in another solar power plant in California that will send electricity to San Diego Gas & Electric when completed in 2014. Google figures that if they can provide a cleaner energy source to consumers this can benefit them in a way. Many people in California that are using Google’s search engine and other products may be powered by Google themselves. (Forbes) I see this as positive branding for Google in the public eye. I think it makes sense and they have the money to do it.

The benefits of solar energy are blatant. We have to come to agreements with untrusted outside sources for fossil fuel imports and these fossil fuels are detrimental to the environment. Though solar energy is expensive to implement across the country, it is likely that in the long run it will increase economic security to US citizens. (The Energy Collective)

Solar energy use appears to continue to increase year after year. Though many investors don’t fully believe in solar energy being financially sensible, there are still enough that do believe in it to continue the growth. Money is always the issue, but solar energy makes long-term sense which will most likely ensure that it will continue to progress in the world.

From 0 centimeters away, the light intensity was the highest as expected. As the distance increased, the light intensity increased, though we did have some strange decreases. They weren’t substantial, but they were surprising.

We then moved on to using color filters on the light to see how that would affect the intensity. All of these measurements were done from 0 centimeters away. With the lighter, more clear, colors, the light intensity was greater. Our darkest color, purple, gave us the lowest intensity.
