Read this article about a study that looks into lifetime energy use of the huge Hummer versus the supposedly “green” Toyota Prius hybrid car, including manufacturing and factoring in the Hummer’s expected 300,000 mile lifetime and the Prius’ 100,000 mile lifetime.
When you pool together all the combined energy it takes to drive and build a Toyota Prius, the flagship car of energy fanatics, it takes almost 50 percent more energy than a Hummer – the Prius’s arch nemesis.
A quick Google search turned up this link to the “Dust to Dust Automotive Energy Report” referred to in the article. I am wary of this research, but it is important to take into consideration the much shorter lifespan of the hybrids and the environmentally expensive batteries it uses–just because it seems “green” doesn’t mean it’s ultimately better for the environment. Similarly, decreasing global efficiency and wealth in the name of Global Warming may harm the environment more than help it–only comfortably wealthy people worldwide have time to worry about whether the global temperature is a few degrees higher, others are just trying to get by.
