With new inventions and modernization in the field of technology the global environment scenario is becoming worse day by day. The consumption of energy is increasing, limited resources of fossil fuel and their cost is increasing the requirement of renewable energy sources. This resources are basically a part of Earth's natural environment .This are obtained from natural resources such as wind, biomass, sunlight, green energy, tides, and geothermal energy. Electricity generation is one of their important
really damage them. In the long term, there can be a high return on investment due to the amount of free energy a solar panel can produce, it is estimated that the average household will see 50% of their energy coming in from solar panels. 2.5 Disadvantages Solar panels can be expensive to install resulting in a time-lag of many years for savings on energy bills to match initial investments. Electricity generation depends entirely on a countries exposure to sunlight; this could be limited by a
servers nested of installing them on costumer's computer. [2] Because there are some of problems in Cloud then Fog computing appeared. Fog computing extend cloud computing and complete each other by using same resources but each concept has advantage and disadvantage [1]. Fog similar to Cloud computing but there is some difference between them, Fog computing is more denser in geographical distribution and location than Cloud computing, it is close to the end user ,so that provide a faster experience
programming, the central unit will act on certain circuits related power signals picked up by the field elements concerned. [2] 2.5. Advantages and Disadvantages. Here, in this chapter, advantages and disadvantages will be defined. Let's start with advantages first. Next will be exposed the main of them: a) Energy saving: It is the biggest advantage, because when you can program all the devices you do not need to be spending all day. This is seen especially in the heating system
