GREEN COMPUTING: Efficient and Eco-Friendly Computing

With rising energy cost and growing environmental concerns, GREEN COMPUTING is receiving more and more attention. Software and system architectures play a crucial role in both computing and telecommunication systems, and they have been analysed for performance, reliability, maintainability, and security. Yet, little work on analysis based on the amount of energy that the CPU/processor will consume has been reported. Since most communication systems have to run 24/7 (e.g., most server farms, servers in a cloud computing infrastructure), the energy consumption of a system based on a specific software architecture is of great importance. For example, high energy consuming always leads to higher operational cost of the system. High energy consumption also implies more heat produced, thus, more power is required for cooling-down. As the number of computers is increasing day by day, so is the amount of electricity consumed by them which in turn is increasing the carbon content in atmosphere. This problem has been realized by the researchers and several corrective measures are being taken which help in minimizing the power usage of computers and this process is called as Green Computing

Retrofitting of Existing Scooter into Hybrid Electric Scooter

In India, the usage of two-wheelers for daily activities is high. Thus, consumption of petrol is on the rise. If the spending of a country is considered then 80−90% spending is done to pay import bills on petroleum products, which are counted as the country’s expenditure. The final result is a hike in the price of petrol and hence rising inflation. India is now the fourth largest emitter of greenhouse gases in the world. The transport sector accounts for 13% of India’s related CO2 emission which is mainly high in the traffic. Deployment of electric vehicles in large numbers is hindered by a variety of barriers. Scaling up electric vehicle’s penetration and realizing their full potential would be required. For this situation, now one of the solutions is retrofitting of existing scooters into hybrid electric scooters. Instead of turning existing petrol vehicles into scrap, this can be utilized as hybrid electric vehicles, as nowadays, focus of government is on “National Electric Mobility Mission Plan 2020” (NEMMP 2020). Thus, the aim of our project is to enhance the capacity of cities to improve mobility with lower CO2 emission. It can be a valuable contribution to achieve NEMMP 2020. The system proposes a solution by retrofitting existing scooters into hybrid electric which runs on Internal Combustion Engine. Here, by using scooter that has 80cc petrol combustion engine. The front wheel is replaced by an electric hub motor. It becomes a 2-wheel drive scooter with the hub motor driving the front wheel and conventional engine powering the rear wheel. Our main aim is to increase mobility and to improve the performance efficiency of existing vehicles. System proposes three switching modes here; Economy mode (Propulsion using motor only), power drive mode (propulsion using engine only) and hybrid mode
