Alternative/Renewable Energy

 

How Does This Technology Work?

Picture
Solar energy can be used in two ways.n  One way is that the heat can be used to heat fluid wich produces steam that powers generators.  The second way is photovoltic or pv devices which changes sunlight directly into energy by taking pv cells and grouping them into the panel.

What are the Negative Aspects?

Picture
Three drawbacks for this energy source are that the amount of sunlight that arrives on earth is not always constant.  The second is that the sun does not deliver tha much energy in one place at any given time so a large panel is required.  Third is the price of installing a solar panel system is expensive wich is the reason why many people do not have them.

What Percentage of US Energy Comes from this Technology?

In 2007 America only got 12 percent of there power from solar powerd machines.
