Creating a City-Wide Energy Internet: A new study on urban infrastructure

Creating a City-Wide Energy Internet: A new study on urban infrastructure | green streets | Scoop.it

A new research study addresses the issue of the expanding populations in cities, and provides a solution for adapting urban infrastructure for the needs created by increased density and growth.


Drawing our attention to one core idea that can make our cities more liveable for good, ‘The Time Is Right for Connected Public Lighting Within Smart Cities‘, is a study that looks into the key concepts of urbanization but applies them to a specific context of “an intelligent, networked public lighting infrastructure”. The study dissects the current issues well, reminding us that the urbanization pattern across the world leads to an obviously problematic upswing in energy and resource demand, which in turn threatens the strong identities (inter-city competition and economic performance) that cities across the planet are attempting to shape and maintain.


The solution, according to the report, is the deployment of highly efficient connectivity within cities whether that be information, operational or communication systems – the solution is required urgently. It seems clear that connecting lighting infrastructures will minimize a city’s resource intake, reduce its carbon footprint and make it more resilient and future-proofed. The ripple effects of better lighting systems in cities include safer and more liveable streets (less crime, more appealing urban space and better road safety) and adds to a city’s pull factors for multi-national organisations and tourism...

What Makes Some Cities Greener Than Others

What Makes Some Cities Greener Than Others | green streets | Scoop.it
Today I turn my attention to the economic, demographic, and other factors associated with cities and metros that have lower levels of carbon emissions.

 

Several Martin Prosperity Institute colleagues and I [Richard Florida] took a simple, straightforward statistical look at several things research and common sense suggest should be associated with higher and lower levels of carbon emissions.

We measure emissions three ways, as a function of population (per capita), workforce (per worker), and economic output (per economic output). All the caveats regarding correlation not being causation apply. However, our findings underscore the fact that carbon emissions are linked as much to the way we live as how we produce and manufacture things...

How Urban Parks Enhance Your Brain

How Urban Parks Enhance Your Brain | green streets | Scoop.it
A break from the bustle of the city can do your mind good, recent research shows.

A couple weeks ago the folks at Cracked told readers that "living in a city makes you dumber." There are a number of flaws here — beyond the obvious one of getting your science news from Cracked — but the research at the center of the claim has some relevance to cities worth considering nonetheless. What it tells us is not so much a story about the hazards of city living as it is about the benefits of city parks.

The original study at issue here, which I'm familiar with from earlier work, was published back in 2008 in Psychological Science [PDF]. A research team led by Marc Berman of the University of Michigan gave participants a standard memory and attention test then assigned some of them to walk through downtown Ann Arbor, and others to walk through the impressive campus arboretum. The participants were tested again upon their return, and beyond a doubt the group that took the nature walk scored significantly better...
