Role of Renewable Energy in “Grid 2 Vehicle” Concept
“Will Power Grid be able to handle increased electricity demand from EVs (Power Requirement Surge during peak hours).”
Power Transformer has come into existence with the growth of civilization and industry, where there is a great necessity to channel more power into machines. These are the best solution to deliver massive power supply within the industry. They connect each house and industry to the grid but are also the most susceptible and distressed elements of the system. Even a single overloaded transformer can corrupt power quality in other residential areas. Having said that, the present transformers should be able to foster the mega revolution in automobile industry, Electric Vehicles.
Let us imagine a situation where electric vehicles outnumber the present ones on the road. An EV with a typical tesla battery specification would need more than 266 A charge, which is roughly equal to the daily power needs of 10 small household. Thus, present transformers need an up-gradation to a more advanced design that can handle a higher load reliably, which will need huge capital to rebuild and multiply across the country.
The game does not end here. There are numerous possibilities to handle charging of EV’s in large-scale and regenerative energy is one of them. Power regeneration is the process of recovering kinetic energy created by a motor during stopping or braking and converting that energy to electricity and feeding it back into the system. For instance, if an EV travels all day long and uses its own energy to self-charge, then on returning home, we might need to charge it just 35 percent against 100 percent (as efficiency of regenerative high to achieve 65% of battery charge) This will put less strain on grid and it can function efficiently.
The Paris Agreement is a bridge between today’s policies and climate-neutrality before the end of the century. The central aim of Paris Agreement is to strengthen the global response to the threat of climate change by keeping a global temperature rise this century well below 2°C above pre-industrial levels from the years 1850-1900. It also talks about a firmer goal of limiting the temperature increases to only 1.5°C above pre-industrial era levels, to undertake rapid reductions of global emissions thereafter in accordance with the best available science. To reach these aspiring goals, appropriate financial flows, a new technology framework and an enhanced capacity building framework will be put in place, thus supporting action by developing countries and the most vulnerable countries, in line with their own national objectives.
India is already experiencing a warming climate. Unusual and new spells of hot weather are expected to occur far more frequently and cover much larger areas. Under 4°C of global warming, the west coast and southern India will shift to new, high – temperature climate regime. This calls for complete revamp to sustainable energy.
Renewable energy is need of the hour. It is the only best alternative which provides substantial benefits for our climate, our health and our economy. It dramatically reduces global warming emissions, improves public health, and provides jobs and other economic benefits. In an 80 percent renewables future, carbon emissions from the power sector would be reduced by 80 percent, and water use would be reduced by 50 percent. Above all, if power generated by renewable energy sources are incorporated in each and every household of our society in a sustainable way, then wouldn’t it solve our problems! To make it a reality, we need strong support from Government in terms of subsidies, policies and most importantly awareness.
