The claim that a Hummer H3 SUV has a lower life-cycle energy cost than a Toyota Prius hybrid caught the interest of the media and the public when the automotive marketing company CNW Marketing Research, Inc. released its 2007 study, “Dust to Dust: The Energy Cost of New Vehicles From Concept to Disposal.” This report finds that the CNW Marketing Research, Inc. study presents selective and unsupported assumptions that seriously distort the final results. A re-analysis with peer-reviewed data leads to a completely opposite conclusion: the life-cycle energy requirements of hybrids and smaller cars are far lower than Hummers and other large SUVs.
There is broad recognition that adapting to climate change, coupled with the need to address aging infrastructure, population growth, and degraded ecosystems, will require rethinking programs and policies and investing in our natural and built water systems.
This is the latest in our What Happens Next series. The increasing scarcity of drinking water is beginning to capture the world's attention -- but surprisingly, an innovative solution might just be found in one of the Earth's driest places.
Stormwater has traditionally been managed to mitigate flooding and protect water quality. However, its potential as a local water supply has gained recent attention in water-stressed areas. As climate change increases the risk of both floods and droughts in California, urban stormwater capture also offers a significant opportunity to enhance community resilience.
