Recycling makes $en$e – Waste Management World

See on Scoop.itGreen & Sustainable News

For an increasing number of municipalities across Pennsylvania, recycling is as good for the pocketbook as it is for the environment.  That’s been the case in Cranberry, where modern collection methods and recycling programs have lowered collection fees for residents.

Duane Tilden‘s insight:

By limiting how much goes into landfills and boosting totals of recycled goods, municipalities such as Cranberry have become eligible for state grants – either to operate recycling programs or to expand existing ones.

The amount of waste the municipality sends to landfills was 7,619 tons last year, compared with 11,030 tons in 2004. The average amount recycled per person was 670 pounds last year, up from 115 pounds in 2004.

The Most Important Man in Energy Storage? Try Archimedes – Forbes

See on Scoop.itGreen Energy Technologies & Development

A growing number of energy storage start-ups are promoting the idea that the most economical, most expedient ways to store power revolves around harnessing the four elements of the ancient world: earth, air, water and fire.

Duane Tilden‘s insight:

Energy Cache, for instance, is developing a system that resembles a ski lift for gravel. Gravel is ferried uphill during the day by a series of buckets, and then dropped during peak power hours. The system essentially provides the drop in elevation nature left out.

An Energy Cache system could be erected at a large number of abandoned mining sites, where there is plenty of gravel and an existing grid connection,  […] Along with the physics, the company is analyzing algorithms to ensure smooth power deliver on demand for the power grid. …

Going for Green or Growth? | Sustainable Cities Collective

See on Scoop.itGreen & Sustainable News

Why are economic and social issues still not seen as interdependent with environmental issues, requiring an integrated, coordinated approach? Or is this fact known but simply not acted on because of power relationships?

Duane Tilden‘s insight:

…We need to broaden our idea of progress and success, adopting prosperity instead of GDP growth because it encompasses general flourishing, thriving, general wellbeing, happiness and health as well as economic factors – socio-economic goals should not continue to be geared to more and more money for a few. Efficiency needs to replace waste.

… without an integrated and coordinated approach to social, economic and environmental issues we won’t have dynamically stable, secure ways of living that are able to persist over time.

DOE, Duke Renewables, Xtreme Battery unveiling giant renewable battery system

See on Scoop.itGreen Energy Technologies & Development

It’s not your typical AA battery. Next Thursday (March 28) Duke Energy Renewables—a Duke Energy subsidiary, the Department of Energy and Xtreme Power will be on hand at the 153 megawatt Notrees Windpower Project, in Ector and Winkler counties,…

Duane Tilden‘s insight:

"The battery was deployed at the site to provide energy storage for the wind farm, helping to stabilize its output to the grid. Such battery systems are being considered for solar installations as well. “Battery storage is an important innovation to address the variability of wind and solar energy generation,” said Duke Energy Renewables President Greg Wolf. “Developing an expertise in this advanced technology will enable us to expand the use of renewable energy, better integrate it into the power grid and become even more efficient at serving our customers.”"

 

"The project has been in the works for a while, at least since 2009 when Duke Energy matched a $22 million grant from the DOE to install large-scale batteries. The grant came from the American Recovery and Reinvestment Act of 2009 (ARRA). It was one of 16 grants totaling $185 million that the DOE’s Office of Electricity Distribution and Energy Reliability made for such storage projects. Each project is cost-shared with the project owners, with the DOE making no more than half the investment. Other projects that received grants included compressed air energy storage, flywheels and advanced batteries. The devices being installed help with frequency regulation, smoothing of a photovoltaic installation, ramping for wind, and time shifting for a fossil fuel plant."

Apple Hits 100% Renewable Energy in its Data Centers » Data Center Knowledge

See on Scoop.itGreen Energy Technologies & Development

Apple said Thursday that it has achieved 100 percent renewable energy at all of its data centers, including facilities in North Carolina, Oregon, California and Nevada.

Duane Tilden‘s insight:

The road to renewable was a formidable one. Apple doubled the size of an already huge solar array in North Carolina, buying another 100 acres of land to support the expansion.  The two separate 100-acre solar arrays in Maiden, N.C. each produce 42 million kilowatt-hours (kWh) of energy annually. Apple also uses biogas from nearby landfills to power Bloom Energy Server fuel cells at its Maiden site.

 

Although it’s been secretive about the project, the company has been vocal in its plans to use renewable power exclusively for its new data center in Prineville, Oregon. That energy will come from a mix of sources, such as wind, hydro, solar and geothermal power.
