5. ENVIRONMENTAL SENSORS
To heal the planet, we need to measure it. Distributed sensors are one of the unsung technologies allowing that to happen, and the continued spread of the networked sensor environment will be one of the undergirding technologies behind nearly every sustainability effort imaginable.
6. BATTERIES
Power is the limiting factor holding back a lot of green technologies. Wind and solar, for example, are capable of generating vast amounts of electricity, but adoption of the technologies has been throttled by a major shortcoming: Sometimes it isn’t windy or sunny. Electric cars, similarly, are making huge strides, but until range increases and charging times diminish, fossil fuels are going to rule.
