Yet, given the enormous global pressures that we face, including vastly unequal incomes and massive environmental damage, we must find new technological solutions to our problems. There is no way, for example, to continue expanding the global use of energy safely unless we drastically alter how we produce electricity, power automobiles, and heat and cool our buildings. Current reliance on coal, natural gas, and petroleum, without regard for CO2 emissions, is now simply too dangerous, because it is leading to climate changes that will spread diseases, destroy crops, produce more droughts and floods, and perhaps dramatically raise sea levels, thereby inundating coastal regions.
The National Academy of Engineering identified some possible answers. We can harness safe nuclear energy, lower the cost of solar power, or capture and safely store the CO2 produced from burning fossil fuels. Yet the technologies are not yet ready, and we can’t simply wait for the market to deliver them, because they require complex changes in public policy to ensure that they are safe, reliable, and acceptable to the broad public. Moreover, there are no market incentives in place to induce private businesses to invest adequately in developing them.
Consider carbon capture and sequestration. The idea is that power plants and other large fossil fuel users should capture the CO2 and pump it into permanent underground storage sites, such as old oil fields. This will cost, say, $30 per ton of CO2 that is stored, so businesses will need an incentive to do it. Moreover, public policies will have to promote the testing and improvement of this technology, especially when used at a large scale.
New kinds of power plants will have to be built to make carbon capture economical, new pipelines will have to be built to transport the CO2 to storage sites, and new monitoring systems will have to be designed to control leaks. Likewise, new regulations will be needed to ensure compliance with safety procedures, and to assure public support. All of this will take time, costly investments, and lots of collaboration between scientists and engineers in universities, government laboratories, and private businesses. Moreover, this kind of technology will be useful only if it is widely used, notably in China and India. This raises another challenge of technological innovation: we will need to support the transfer of proven technologies to poorer countries. If rich countries monopolize new technologies, the goal of worldwide use to solve worldwide problems will be defeated. Thus, technological developments should involve a collaborative international effort from the start.
All of this will require a new global approach to problem solving. We will need to embrace global goals and then establish scientific, engineering, and political processes to support their achievement. We will need to give new budgetary incentives to promote demonstration projects, and to support technology transfer. And we will have to engage major companies in a new way, giving them ample incentives and market rewards for success, without allowing them to hold a monopoly on successful technologies that should be widely adopted.
I believe that this new kind of global public-private partnership on technology development will be a major objective of international policy making in the coming years.
