Continuing this series on Renewable Cities PechaKucha presentations, Mark Z Jacobson, a legend in the world of renewable energy research, gave an excellent, information-packed presentation on the opening night of the Renewable Cities Global Learning Forum (see our Renewable Cities archives here).
I love that he started by highlighting the insane health costs of burning fossil fuels, noting that “air pollution kills 4–7 million people prematurely each year,” with about 20% of those people being children under the age of 5 years old. Insane. It was particularly interesting seeing the image of a 1970s nonsmoking LA teenager’s lungs, which had suffered the equivalent of smoking two packs of cigarettes per day. Air pollution in much of the world today is comparable to LA in the 1970s….
Of course, Mark also highlighted global warming, which could even dwarf the negative effects of air pollution.
One of Mark’s big projects has been finding out how the world could switch 100% renewable energy using existing technology (and note that this is in reference to all human energy usage, not just electricity). You can see a quick run-through of the general plan in the presentation below. Enjoy!
