What is the efficiency of energy conversion?
"Energy transformation efficiency" is a term used to describe the amount of useful power of energy, which is the result of a given energy input in a device used to convert energy from one form to another. For example, the solar energy converter converts the radiant energy from the Sun to a usable electricity that can be used to power electrical equipment. The energy performance ratio to the energy input of this process describes the overall efficiency of the conversion of the solar changer. Knowledge of efficiency is important if someone wants to estimate the amount of useful output received from a given conversion or device process. In some cases, the overall efficiency over time will be affected by non -related factors; For example, the solar energy converter only works during the day and is negatively affected by clouds.
The gear device may lose efficiency by different means. Some devices intended to convert one form of energy into another will lose energy as heat. Engine intended forFor example, emotionally chemical energy for work or motor energy can release some energy as heat. This heat does not contribute to the required work, so it is waste energy. As such, it reduces the overall efficiency of energy conversion, because only the desired output is considered in the proportion of inputs.
The ratio of the transformation efficiency of the output to input is generally expressed as a percentage from zero to 100 percent or as a number from zero to one. This number has no unit or dimension; It is simply the ratio of energy obtained from transformation to energy into transformation. A device or process with a high energy conversion efficiency will be closer to one or 100 percent, while low energy conversion efficiency is represented by a ratio closer to zero or zero percent.
efficiency of energy conversion is generally on the description of the device when it is properly and in good circumstanceand. However, it should be noted that many environmental factors may negatively affect overall efficiency, as well as general degradation of the device over time. Clouds can negatively affect the efficiency of the solar energy converter, as well as wind -free days can reduce the efficiency of energy windmills. Even devices with almost perfect energy conversion energy will be almost unnecessary if the energy input source is not simply available.
