Alternative Fuel Choice

Energy is a source of power that makes the world go round. Businesses, residences, automobiles, everything uses energy in some form or another. In the past, fossil fuels provided enough energy for people’s needs. However, as that resource is slowly depleted, people are turning to the energy of the sun and the solar panels that provide it, as an option.

Fossil fuels are made up of hydro-carbon rich resources such as organic materials buried beneath the earth. These organic materials are burned and used to generate steam, which turns a turbine engine. These engines create the world’s energy resources. Unfortunately, fossil fuel as an energy source is messy and creates pollution.

Solar panels offer a source of renewable energy by taking the energy of the sun. Because suns in general have such very long life spans, the energy taken from the sun is reliable and almost permanent. A solar panel uses the energy it absorbs to create electricity, the same power that fossil fuels provide.

Photovoltaic cells, more commonly known as solar cells, are the part of a solar panel that work to change light energy into electricity. Solar panels are made up of many photovoltaic cells. Each actively turns the energy it captures into something people can use.

A solar panel gets its energy directly from the sun. Inside the sun, hydrogen atoms are constantly fusing with helium atoms, causing a constant stream of thermonuclear explosions. This sets off radiation, which pours over the earth as light. Panels set at the earth’s equator can catch this light and store it for use in batteries. A photovoltaic cell that is about one fifth of a meter in diameter can catch sun and turn it into two amps of energy at two volts. Space based solar paneling is even more efficient.

Some solar panels are made from crystalline silicon, while others are made using amorphous silicon technology. The amorphous style of solar paneling is thinner and more efficient than the crystalline kind. Some high efficiency solar cells are constructed using gallium arsenide. However, the expensive process of making them, called molecular beam epitaxy, is not ideal for every day use cells.

Besides using silicon, it’s also possible to make solar panels with plastic. With this sort of technology, it would be possible to have solar cells layered over the screen of, say, a laptop computer. This would provide a constant source of power where it is needed. However, plastic solar cells aren’t prepared yet to gather up more than eleven percent of energy that their silicon counterparts gather.

The world’s trend in energy is slowly changing. People are seeking out new forms of creating energy, especially from renewable sources. Because so much of what humanity relies on is derived or a part of the energy cycle, finding energy that is clean and efficient is very important. Enough light strikes the earth every day to provide for the world’s energy needs for a year. Solar panels are a way of capturing this energy, cleanly, without a harsh impact on the environment.
