Proliferation of wireless devices and networks detrimental to environment

Cloud computing should be driving sustainable development, but its turning us into energy consuming monsters, write Stuart Newstead and Howard Williams

Duane Tilden‘s insight:

>There is a familiarity and comfort in our almost-everywhere connection to always-on communications networks and to the ever-increasing array of services they deliver us. We don’t just consume these network services directly, they give us what economists call “options” – options to connect, options to seek out new services, options to find new information. Clearly we don’t use this network services 24/7, but we value highly the options for instantaneous and simultaneous access at any time.

Cloud-based applications – those stored and managed by massive data centres run by the likes of Amazon, Google, Facebook or Apple – are providing step changes in the financial and environmental efficiency of delivering these services. But the centralising power of the cloud has its corollary in the dispersing effect of wireless networks and devices.

In wireless networks and devices we see fragmentation, duplication and a fundamental shift from mains power and green sources of energy to battery powered always-on devices. In environmental terms here lies the rub. Rather than the “aggregation of marginal gains” (the Sir Dave Brailsford strategy that has propelled success in British cycling), in which lots of tiny improvements add up to a large visible improvement, we are witnessing the aggregation of environmental disadvantages from billions of low-powered but fundamentally energy-inefficient antennas and devices providing the ‘last metre’ connectivity to global networks.

Wireless networks and devices, technologies that should drive sustainable development, are turning into energy-consuming monsters.<

Wing Power Energy focuses on micro-wind systems for cell towers, buildings – Boston Business Journal

See on Scoop.itGreen Energy Technologies & Development

While large wind farms like the Cape Wind Project routinely take years to get approval and support, Wing Power Energy is focused on micro-wind systems – small generators that produce less than 10 kilowatts…

Duane Tilden‘s insight:

[…]Wing Power Energy’s technology is a vertical, four-blade wind propeller combined with a solar panel, which together can generate as much as 3.5 kilowatt hours of electricity.

Recently, the company put up a live demonstration in the City of Salem, consisting of three hybrid wind/solar turbines on the rooftop of a municipal parking garage powering 4G LTE enabled Verizon wireless equipment, including two video surveillance cameras, one digital signboard and a complete wireless network, completely off grid and running only on the power generated by the turbines. The company now has about 15 systems up and running or in the works around the country.
