1 Purpose The purpose of this document is to provide a brief overview of refrigerants R410A and R407C, describe their characteristics and compare their environmental impact, regulatory compliance and resulting system efficiency.407C and R410A R407C is a non-ozone depleting blend of three HFC refrigerants (R32, R125, R134A) and was designed to match as closely as possible R22 pressure and performance to allow a smooth transition from R22 to R407C.
Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth's surface, and rotation of the earth. Wind flow patterns are modified by the earth's terrain, bodies of water, and vegetative cover.
How is wind helpful to Earth? Wind is the fastest growing source of electricity in the world. It's often one of the least expensive forms of renewable power available. Some experts say it can sometimes be the cheapest form of any kind of power. Generating power from the wind leaves no dangerous waste products behind.
