Here in Spain, first world consumerist insolidadrio some extent, the government has decided that speed maximum is 110 km / h on motorways . I will not go look at all energy measures Zapatero government, but I will argue, from an environmental perspective, sustainability, this measure. There can be no doubt.
As I recalled the other day my colleague Luis, most consumer compare cars are based on a speed of 90 km / h, when they want to show is its low power consumption, but the hypocrisy is that the cars come prepared to run-and-consume much more. According to Institute for Energy Diversification and Saving of Energy (IDEA) the average consumption of a car Spain gasoline when traveling at 120 km / h is 8.58 liters per hundred kilometers. A 110 km / h, low consumption to 7.64 liters. The saving between one speed and one is 0.94 liters per hundred kilometers, 11%. I agree with Greenpeace in saying that competitiveness increases with energy saving measures, not the reverse . This reduces the dependency on oil (now accounting for half of our energy), emissions of greenhouse gases, pollution, noise pollution, accidents ...
Clearly under this measure, all of conjunctural you want to see, is the sustainability debate the Earth, solidarity with future generations, consumption patterns and life accept that power is limited and live accordingly.
