Apart from electricity, one uses petrol/diesel for driving vehicles and lpg for cooking food. can you estimate the amount of total energy used or consumed in terms of kilo-watt-hour or kwh?

Motorists fill up their vehicles at a Shell station on July 22 in Denver. Phasing out the sale of gas-powered cars once seemed laughable. It's now inching closer to reality. David Zalubowski/AP A few years ago, when the advocacy group Coltura called on America to stop using gasoline, it prompted mockery. Coltura had been waging a war against gasoline for a few years by this point, but its primary weapons were things like music and performance art. One piece featured actors inside a clear plastic bubble panicking as it filled with simulated exhaust. Then in 2017, Coltura's co-executive director, Matthew Metz, published an op-ed calling for Washington state to phase out gas-powered cars completely. A Seattle columnist A lot has changed in four years. Tesla is now the world's most valuable automaker. Multiple automakers say they will cease production of gas- and diesel-powered cars within the next two decades. And what was once a fringe idea is now part of a "More and more countries are announcing targets to to phase out internal combustion engine vehicles at the national level," Sandra Wappelhorst, who has Plans for 100% electric vehicle sales go mainstream The climate talks that recently wrapped up in Glasgow featured a non-binding call for all vehicles sold worldwide to be zero-emission by 2040. The European Union is considering a zero-emission mandate that would kick in five years earlier, in 2035. The idea is percolating from the heads of government down to individuals. ...

Gasoline vs. Electric Cars: Energy Usage and Cost By Stanislav Jakuba -- February 4, 2015 “Should electric cars become ubiquitous, electricity will be taxed to yield that revenue. Electricity cost would also be higher if some 95 percent of U.S. electricity were not generated by the cheapest methods – burning fossil fuels, hydro, and nuclear reaction. Should it originate from wind and solar, it would cost three-to-eight times more: a dime per km with wind, a quarter per km with solar.” There are many variables that determine the relative economics of an economic petro-powered vehicle ( While the Civic had a slight advantage a year ago with gasoline at $3.50 per gallon, the advantage for conventional vehicles has jumped with today’s lower pump prices. Also, should electricity for transportation be taxed at the level of gasoline and diesel, the economic gap would widen. This disadvantage of electricity would further widen to the extent that the grid is powered by wind and solar. The analysis follows. Driving Distance Let’s start the comparison by investigating the driving distance “on full battery or tank.” As with all vehicles, that distance is influenced by the driver’s skill, but with electric cars there is, in addition, the ambient temperature dependence; it impacts their driving range far more than cars with internal combustion engines. The Society of Automotive Engineers (SAE) published the average driving range of the Nissan Leaf models vs. temperature; the chart is re...

There's a very good reason that humans are still using gas-powered cars. Despite the negative side effects of combustion—it releases not just energy, but carbon dioxide—the simple fact is that you can get more energy out of gasoline than you can from other energy sources. A typical car can travel 30 miles on just one gallon of gasoline. That's crazy! Soon enough, the oil that gasoline comes from will become Instead of measuring the total energy stored, it's best to consider the So let's say I want to replace a liter of gasoline with some other energy storage stuff of the same volume. With different energy storage, how far could a liter of energy take a car? (Yes, I'm switching to volume units of liters instead of gallons but I am going to stick to distance in miles—crazy, right?) But what if I replace the gasoline engine with a lithium-ion battery and an electric motor? In this case, there are two things that change. First is the starting energy. A lithium-ion battery has an energy density of about 2 MJ/L (different batteries have different energy densities). Second is the efficiency. Since a battery with an electric motor doesn't have to waste energy in the explosion of gasoline, it has an overall efficiency of about 50 percent. So, that 2 MJ in a 1 liter battery would be able to put about 1 MJ towards driving a car. The car will still have the same amount of energy loss to friction and air resistance so that this 1 MJ would be able to move the car about 1 mile (OK—actual...
