Smart cities, the digital revolution and energy

The Digital and Electronic Revolution some important milestones

From the first transistor in 1947, to today where transistors vastly exceed the number of people on the planet, the digital revolution is upon us and entering the built environment.  The digital time line shows the introduction of the first computer in the late 40’s early 1950’s, video recorder in the 1960’s, the microprocessor and texas calculator in the 1970s, 1980 when word processing packages, spreadsheets and mobile phones came into the market and the internet was first mentioned. In the early 1990’s the internet became open and commercially available. 2007 the apple phone introduced and now smart technology is entering the built environment.

McKinsey (2009) Unlocking energy efficiency in the US economy

“The research shows that the US economy has the potential to reduce annual
non-transportation energy consumption by roughly 23 percent by 2020, eliminating
more than $1.2 trillion in waste—well beyond the $520 billion upfront investment
(not including program costs) that would be required. The reduction in energy
use would also result in the abatement of 1.1 gigatons of greenhouse-gas
emissions annually—the equivalent of taking the entire US fleet of passenger
vehicles and light trucks off the roads.”
