**4. Conclusion**

Thus, from the above references in order to enhance the efficiency of renewable energy continuous monitoring becomes necessary which is carried out using various sensor devices. Everything is made simple and easy using evolving technology IoT is shown in **Figure 4**. If renewable energy sources keep IoT at its forefront the benefits it presents are.

Physical monitoring of farms such as solar, wind, hydropower etc. becomes impossible. IoT sensors help in monitoring and man-aging generation, transmission and distribution across remote locations. Continuous monitoring ensures that all equipment work efficiently thus helps in improving reliability.

Renewable energy equipment has complex constructions. They require an adjustment according to environmental change. IoT implemented wind, solar have better control and also helps in reducing operational cost. The advanced monitoring using IoT improves safety on the premises to avoid disaster by providing timely alerts, automatic shutdown etc.

IoT powered smart grid have the ability to detect changes in the demand supply of electricity and is able to react to these changes automatically and provide needed information to manage demand. Thus, improves the energy efficiency.

Energy equipment housed IoT sensors constantly monitor, analyze and predict the energy requirement. The building analyzed da-ta helps in managing infrastructure or to modify the existing infra-structure based on demand. Sensors help in isolating affected area and automatically reroute power as soon as the problem is solved.

Based on accurate measurement using sensors IoT can predict the precise energy generation thus optimizes production and control. The energy consumed reports can be sent to the users so that they can identify the energy wasted and can save energy bills.

Though IoT becomes part of consumers and industries, the problem that revolves around IoT is lack of security. For example, on 23rd December 2015 at Ukraine first power grid cyber-attack took place. The malware disrupted three energy distribution companies. It switched off 30 substations. It left 230000 people without electricity for a period of six hours. Since, IoT devices share information over the internet. Thus, the data hacked affects the privacy of consumers and industries to an extreme level. In order to overcome the issues IoT devices must develop top notch encryption for sharing information over the internet. Apart from this it creates unemployment in developing countries since it replaces human intervention with thing to thing communication. Moreover, people look out to do their task easier with less effort. IoT makes their work simpler and easier at the same time it makes the people lazy and dependent on technology.

In forth coming years IoT with renewable energy transform the energy sector by continuous monitoring, performing control actions to improve the efficiency as well as to distribute the energy harnessed efficiently. IoT implemented with renewable energy saves consumer time as well as money. It reduces the carbon foot print. In future the renewable energy sector will become smarter, efficient and more reliable. Though IoT has many advantages it must put effort to determine the ways in which it can combats its demerits.
