Three comments I really liked from the premier conference on cleantech:
Art Rosenfeld, California Energy Commission – It’s all about cool white roofs to combat climate change. Art is one of the deans of energy efficiency in California. It’s been long known that white roofs can cool a building and help reduce the heat island effect in cities (cities are always hotter than the country, basically because they make more heat, and shifting from trees to concrete, asphalt and asphalt shingled roofs both reduces the cooling affects of aspiration and absorbs a larger portion of heat into the phyiscal environment).
So Art is now effectively calling for step by step, low cost and simple geoengineering through policy to combat both energy efficiency demons and climate change. E.g, not only do cool white roofs reduce heat in the city, they reduce the cooling bill in the building, and reduce GHGs from energy use. He posits that a shift from black roofs to white roofs and/or shifting roof design to flatter roofs that are more effective in white roofs would save literally billions upon billions of tons of CO2e over time, with no measurable cost difference.
So, call it the affirmative action program for cleantech, but color matters.
Sheeraz Haji, CEO Cleantech Group – It’s all about Data. The idea is pretty simple – everything in cleantech from here on out – e.g. smart grid, energy efficiency, solar performance, water use, EVs, etc all depends on more, cheaper, faster, more granular, timely and better data and the analysis it can drive. Sheeraz’s question to define future opportunities in cleantech is, “so what does data need?”
John Denniston, Kleiner Perkins – It’s all about food. Think food security, food v fuel, water use, fertilizer source and ag run-off, crop yields, etc. I love this topic. For those of you who haven’t heard of him, go google Norman Borlaug, the recently passed away sage who made possible our ability to not starve and threw Malthus for a loop for the last few decades with dramatic crop yield improvements from his selective plant breeding and fertilizer intensive ag. The favorite argument of the day, which John mentioned, is the “in the next x decades of years we’ll need more food than in the last x – thousands of years”. Right or wrong, the scale is sure changing.
So, whether your answer to John’s all about food is less people, more GMO, more technology, more water efficiency, or shifting diets, we’re going to need another Norman Borlaug or life is gonna suck.
