Moving from oil to sustainable energy
generation In near future, oil production will further fall ,but
energy consumption will
continue to rise
We need to find fossil alternatives, preferably sustainable and
green
Need to ramp up sustainable alternative
Meanwhile curtail our consumptions

V2G Basic Math
Average car driven 1 hour/day time parked is 23hours/ day
Daily average travel : 32 km
Practical power draw from car: 10-20 KW
India power generation capacity = 236.84 GW ; load =27.21 MW
India 70 million cars x 15 KW = 1,050 GW
Power in the cars >> generation or load

Plug-in hybrids (PHEVs)
Typical vehicle usage is for urban commuting
PHEVs will mean we chose to plug-in our vehicle to the grid
We need to make the grid connection to the battery through a
bi-directional inverter
Charge the battery from electric grid overnight so this
energy does not come from oil
