Decades later, in 2006 Al Gore's Oscar/ Nobel Prize winning An Incovenient Truth made an impact on virtually everyone who wanted to listen. The documentary warned us, in a much better researched and packaged presentation than “Limits to Growth”, that the end is neigh: “Humanity is sitting on a ticking time bomb. If the vast majority of the world's scientists are right, we have just ten years to avert a major catastrophe that could send our entire planet into a tail-spin of epic destruction involving extreme weather, floods, droughts, epidemics and killer heat waves beyond anything we have ever experienced. “ Tom Friedman published “Hot, Flat and Crowded”, a call to arms to deal with the challenges and opportunities of global warming, growing population and expanding middle class. Darn...even George W. Bush pleaded with Americans to conserve gasoline by driving less and issued a directive for all federal agencies to cut their own energy use and to encourage employees to use public transportation. And this week Obama said that the US must move quickly to develop clean and innovative sources of energy after years of delay. "We've seen enough. We can remain the world's leading importer of foreign oil, or we can become the world's leading exporter of renewable energy."
Nowadays the concept of “sustainability” has full credibility, almost to a point of becoming fashionable (like Jimmy Carter's cardigan ). We have come to learn about sustainable development, housing, agriculture and even the sustainable South Bronx. The facts are that “the average American generates about 15,000 pounds of carbon dioxide every year from personal transportation, home energy use and from the energy used to produce all of the products and services we consume”. The energy consumption of the average American is almost twice that of a German and three times that of a Pole. Playing on people's conscience may help change behavior. We can trade in our SUVs (disclosure: I am driving a Lexus Rx400h), turn off some lights and empty the jacuzzi (the biggest consumer of electricity). The real change though will come from solutions that not only address these huge issues, but make business sense as well. And there is light on the horizon. Huge companies like General Electric and IBM have developed solutions for the “smart grid”. Highly entrepreneurial green enterprises are getting substantial investor attention. Examples are companies like Better Place, which has launched a new businessmodel for electronic cars, or Tendril, which develops smart grid software.
Infomation Technology is at the heart of the solutions that aim to optimize our scarce resources. IBM claims that “if the U.S. grid alone were just 5% more efficient, it would be like permanently eliminating the fuel and greenhouse gas emissions from 53 million cars. Billions of dollars are wasted on energy that never reaches a single lightbulb.” Tendril has a solution that uses smart plugs containing sensors. A transceiver sends information about energy consumption and patterns. The data gets analyzed and instructions are sent back to the the plug to switch the appliance on or off. This can easily save 10-15% in power consumption at the home or office. Every kilowatt saved in the home saves three at the generating station. Even Google has stepped into the game with their PowerMeter doing what they do best: collecting information, applying analytics and providing users tools to make decisions to reduce energy consumption. Rolls Royce now tracks the performance of 3,500 jet engines around the world in real time, as data is beamed satellite to the company's control room. By analyzing the data it has steadily improved fuel efficiency and over the past 30 years has extended the operating life of engines tenfold. These systems are fairly straightforward control loops: gather the data, analyze it and adjust the settings.
CK Prahalad suggests that government, civil society and companies collaborate to tackle this new phase of resource optimization. The government should contribute with focused investments and regulation, civil society with ideas and grass root approaches and companies with the entrepreneurial and operational capabilities to create commercially viable products. There are big opportunities to improve the supply chains of WalMart (importing over $20Bn in goods from China alone each year) and other large retailers from a green perspective, applying concepts like reverse logistics and extended supplier responsibility. Civil society should look at Walmart as a potential ally rather than a big bad capitalist.
But Sharon Begley writes in this week's Newsweek: “while you're doing all that to reduce the world's energy use and cut emissions of greenhouse gases, keep this in mind: even if we scale up existing technologies to mind-bending levels, such as finishing one nuclear plant every other day for the next 40 years, we'll still fall short of how much low-carbon energy will be needed to keep atmospheric levels of carbon dioxide below what scientists now recognize as the point of no return.” We need profound breakthroughs. Money should flow to where we have the highest chance of finding these and bringing them rapidly to industrial scale. This should be the number one priority after the financial system is cleansed.
By the way, don't forget to turn the lights off for an hour on Earth Day
