How Many Gallons of Gasoline Would it Take to Charge an iPhone?
"This may seem like a strange question to ask, considering iPhones obviously are charged with electricity, not gasoline. But the answer speaks to why gasoline and other liquid fuels will remain an important part of the energy mix in the future.In ExxonMobil’s recently released Outlook for Energy, we predict that by 2040, about 90 percent of the global transportation fleet will still be powered by liquid petroleum fuels – that is, gasoline, diesel, and jet fuel. When asked why that’s the case, Bill Colton, ExxonMobil’s vice president for Corporate Strategic Planning, often starts the discussion using this fact to put it in perspective:All of the energy concentrated in one gallon of gasoline is enough to charge an iPhone once a day for almost 20 years.Clearly, there’s a lot of energy in a gallon of gasoline. And energy density is one of the key factors behind the reliability, affordability, versatility and convenience of any fuel. These are key elements that drive consumer choices today and will continue to drive consumer choices in the future."~Ken Cohen writing on the Exxon Mobil blog on Dec. 14, 2011HTs: Joe and Mark Lais
