Solar Energy

There is a bright future for solar power (no pun intended). On the average sunny day the sun shines approximately 1,000 watts of energy per square meter, enough energy to power all of our electricity needs and excess(“How”).

This plethora of power and will be utilized in the future because we can't afford not to. It is predicted that in 100-500 years our fossil fuels will be depleted:

this means that alternative sources of energy will be a necessity (Exxon).

We consider solar power a renewable resource because it is conitinuosly supplied to us by the sun. When discussing solar technology it is generally broken up into two different categories: photovoltaic and solar-thermal technology. The former converting the power of the sun directly into elictricity and the later utilizing the heat generated by the sun. Both of these are highly praised for their lack of pollution due largly in part to the lack of the need of combustion.

Many factors come into place when deciding what the outcome of solar power will be as a major player in energy technologies. One of the key issues that will decide the future of solar power is, what do we do when the sun goes down? Solar energy can only be extracted during light hours; leaving us to turn to other means at night. The technology to store large amounts of energy from solar power does not yet exist. That means that solar power would best be combined with other power...
