The full cycle charge and discharge efficiency of the Tesla Roadster is 86%, which means that for every 100 MJ of electricity used to charge the battery, about 86 MJ reaches the motor.īringing the math together, we get the final figure of merit of 2.53 km/MJ x 86% x 52.5% = 1.14 km/MJ. This gives us a well-to-electric-outlet efficiency of 97.5% x 97.5% x 60% x 92% = 52.5%.ĭespite a body shape, tires and gearing aimed at high performance rather than peak efficiency, the Tesla Roadster requires 0.4 MJ per kilometer or, stated another way, will travel 2.53 km per mega-joule of electricity.
Natural gas recovery is 97.5% efficient, processing is also 97.5% efficient and then transmission efficiency over the electric grid is 92% on average. "Combined Cycle" is where the natural gas is burned to generate electricity and then the waste heat is used to create steam that powers a second generator.

The H-System Combined Cycle Generator from General Electric is 60% efficient in turning natural gas into electricity. However, let’s assume for the moment that the electricity is generated from a hydrocarbon source like natural gas, the most popular fuel for new US power plants in recent years. The obvious counter is that one can develop grid electric power from a variety of means, many of which, like hydro, wind, geothermal, nuclear, solar, etc. Power Plant Emissions aka “The Long Tailpipe”Ī common rebuttal to electric vehicles as a solution to carbon emissions is that they simply transfer the CO 2 emissions to the power plant. Moreover, the battery isn’t dead at that point, it just has less range. However, dumping them in the trash would be throwing money away, since the battery pack can be sold to recycling companies (unsubsidized) at the end of its greater than 100,000-mile design life. I wouldn’t recommend them as a dessert topping, but the Tesla Motors Lithium-Ion cells are not classified as hazardous and are landfill safe. The answer to the first is short and simple, the second requires a bit of math:īatteries that are not toxic to the environment! Now I’d like to address two repeated arguments against electric vehicles - battery disposal and power plant emissions. When someone buys the Tesla Roadster sports car, they are actually helping pay for development of the low cost family car.

In keeping with a fast growing technology company, all free cash flow is plowed back into R&D to drive down the costs and bring the follow on products to market as fast as possible. Without giving away too much, I can say that the second model will be a sporty four door family car at roughly half the $89k price point of the Tesla Roadster and the third model will be even more affordable. The strategy of Tesla is to enter at the high end of the market, where customers are prepared to pay a premium, and then drive down market as fast as possible to higher unit volume and lower prices with each successive model. Almost any new technology initially has high unit cost before it can be optimized and this is no less true for electric cars. However, that misses the point, unless you understand the secret master plan alluded to above. Are we really in need of another high performance sports car? Will it actually make a difference to global carbon emissions? Even so, some may question whether this actually does any good for the world. Then, over and above that fact, it has twice the energy efficiency of a Prius. This is because the overarching purpose of Tesla Motors (and the reason I am funding the company) is to help expedite the move from a mine-and-burn hydrocarbon economy towards a solar electric economy, which I believe to be the primary, but not exclusive, sustainable solution.Ĭritical to making that happen is an electric car without compromises, which is why the Tesla Roadster is designed to beat a gasoline sports car like a Porsche or Ferrari in a head to head showdown. However, some readers may not be aware of the fact that our long term plan is to build a wide range of models, including affordably priced family cars. As you know, the initial product of Tesla Motors is a high performance electric sports car called the Tesla Roadster.
