ILLUSTRATION - Number of years before the exhaustion of various resources at the global level, assuming a holding geological equal to that of 2006. The data come from the U.S. Geological Survey the report BP Statistical Review of World Energy, June 2008 and an article on Paul Mobbs uranium reserves. Graph from Roll without oil.
Although electrically powered cars are much more efficient than conventional cars, the fact remains that it is not very wise constantly moving vehicle to carry a 1500 kg 75 kg person . should not only consider oil consumption vehicles. It will also be very vigilant on the consumption of metals which will disappear in a few more decades, if they continue to operate at current rates (see chart above).
Faced with this global resource, the author of these notes is convinced that u No real sustainable development of road transport requires a significant investment in public transport , that our governments have a duty to improve, to attract more customers . Carpooling and electric cars urban community are other important elements to help us eliminate our dependence on oil while reducing our consumption of raw materials. Cycling and walking nicely complement the overall environmentally responsible ways. But it also will have to rethink the urban sprawl, promote weeks 4 days and telecommuting.
To minimize the consumption of raw materials in the construction of vehicles such as the group traction wheel motors is that which allows the greatest economy , as we shall see in another post. Besides the wheel motors are ideal for urban transit, as they allow buses to get the maximum energy during their many stops, which minimizes energy consumption. In fact, buses are probably the vehicles that would benefit most from the technology of wheel motors.
