The Internet of Things makes electronics more friendly to the environment and cuts carbon emissions by a significant amount, which is one of its primary benefits. IoT devices can reduce their energy consumption via the use of context-aware automation. For example, refrigerators that turn themselves off when they are not in use and road light bulbs may save approximately forty percent of the power they require.  The Internet of Things is capable of measuring and quantifying the amount of energy that is used by the many connected devices. Because of this, the gadgets can decrease the wasteful use of energy, which in turn minimises their carbon impact.   This enables the device manufacturers to understand the energy consumption of their products and to take control of the energy consumption of their products to benefit the environment. The manual switching between renewable and conventional energy sources may be facilitated by smart grids, which is another characteristic of the Internet of Things (IoT) that can be used to promote energy savings.
