Clearly, increased use of renewable energy will be a prerequisite for future sustainability, which is a core objective for smart cities. With this thought in mind, something recently caught my attention in an article in the Ideas section of the Boston Sunday Globe newspaper. The article, entitled “Boston vs. the Rising Tide,” discussed how, back in colonial days, the effects of ocean tide were once extremely apparent in this city by the sea. And based on the tidal-influenced flooding of downtown during a particularly severe storm this past winter – tides are becoming increasingly apparent once again. This is due in part to the gradually rising sea levels and severe weather patterns we’ve been experiencing courtesy of global warming.
