Silicon is commonly used to make solar cells due to its special chemical properties. A silicon atom has 14 electrons that are arranged in three different shells.
The first two shells which have two and eight electrons each are completely full. However, the outer shell is only half full as it only has four electrons. Thus a silicon atom is always on a look out for ways to fill up its last shell.
In order to do this, it will have to share electrons with four nearby atoms to gain stability. It is just as if each atom has joined four hands to four neighbors. This is what forms the crystalline structure, leading to the formation of a PV cell.

This article is based on the factors that affects the output of a wind turbine. Since wind turbine is one of the purest forms of producing powers. Various factors combine to make an impact on the amount of energy you can generate out of wind like Power in the Wind, Aerodynamics of Blades, Loads, Stress, and Fatigu and Power control and aerodynamic braking system.

Ancient way of converting biomass into energy is just to burn it for producing heat, as humans practiced it for thousands of years. Still this is the most common way for conversion of biomass into energy in United States and elsewhere also.

United States also produce 4 billion gallons of ethanol, which is almost 2 percent of the liquid fuel used in cars and trucks. Same like that contribution for heat is also considerable. But still it can be produced more by better conversion technology and more attention paid to energy crops.

generally people think that by opting for the natural gas, they help in reducing the carbon emissions in the air. though they are right to some extent, however, the best way of helping out the environment is to focus upon producing energy through natural factors like sunshine and wind

Having dished out plenty of solar power info, I got to thinking whether or not the majority of people are even aware of the brains behind the project, the Solar Panel(!)? Or, if you prefer, the “Green-Hornet-side-kick” of the solar energy team. Whatever the metaphor, lets familiarize us with the photovoltaic physical workings of this super hero enigma.
