"Wireless sensors & wireless sensor network

 

The emerging market for wireless sensors and wireless sensor networks is of particular interest as well. Energy harvesting wireless switches and sensors can collect small amounts of energy from their environment. With the advent of ultra low power electronics many sensors can operate by harvesting very small amounts of light from their surroundings, enabling them to register, detect and transmit information wirelessly. These technical breakthroughs reduce the energy needed to transmit a signal. As a result, deployments of energy harvesting wireless sensors make applications feasible, while minimizing maintenance costs, enabling their operation in environments where other technologies (e.g. primary coin cells with their limited lifetime and need for frequent changing) are not suitable."

The Clean Water Act, 40 Years Later

The Clean Water Act, 40 Years Later | Green Energy Technologies & Development | Scoop.it
From Mother Nature Network's Russell McLendon: 1972 was a watershed year for American water.

 

"Forty years later, the law's legacy is hard to overstate. Not only did it empower the EPA to punish polluters, but it helped legitimize the young U.S. environmental movement at a key time in its history. River fires, toxic spills and other crises had cast a national spotlight on water pollution, spurring support for an aquatic sequel to the 1970 Clean Air Act. And unlike its precursor, the Federal Water Pollution Control Act of 1948, this law sought to make all U.S. waters "fishable and swimmable" by a specific deadline (1985), and gave regulators the tools to actually follow through."

 

"Yet as Greenberg and Holman both acknowledge, the CWA is still a work in progress even as it turns 40. An estimated 35 percent of U.S. waters are still unfit for fishing or swimming in 2012 — despite the law's 1985 target of zero percent — and it does little to control diffuse, "nonpoint" sources of pollution like urban stormwater and farm runoff. It's also beset by ambiguity, due partly to a series of court rulings that have raised doubts about which waterways are protected and which ones aren't."

Why Energy Efficiency and Buildings Don’t Mix [Opinion]

Why Energy Efficiency and Buildings Don’t Mix [Opinion] | Green Energy Technologies & Development | Scoop.it
How does the real estate industry make energy efficiency decisions? And what part of the process is holding back adoption? Five main 'friction points' can slow or stop the momentum for energy efficiency adoption by the real estate industry.

 

"The Developer-to-Owner Gap: Income Valuation and Credibility

 

Developers have a crucial role in determining a building’s future energy performance, since they make decisions about building design, including orientation, equipment, and materials. To many real estate industry participants, energy cost savings projections are unpredictable and unfamiliar, and therefore, not fully credible. This view prevents the value of energy efficiency upgrades from being fully reflected in a buyer’s building valuation."

 

"The developer has incentive to invest in improvements that will credibly boost building net revenue. To the degree that energy savings projections lack credibility in the market, developers allocate funds to other building components – not energy efficiency."

 

[Note that the major influencer(s) on energy efficiency design are often not included in the equation as we see in this article... although they are the ones held liable and responsible if the building should fail to function, often long after the developer has gone.]
