German village delivers great green energy blueprint

See on Scoop.itGreen Energy Technologies & Development

Nations as diverse as North Korea and the United States have sent personnel to a tiny village in the east of Germany in a bid to understand its successful energy transformation.

Duane Tilden‘s insight:

…Feldheim is powered by a mix of 43 wind turbines, a woodchip-fired heating plant and a biogas plant that uses cattle and pig slurry as well as maize silage.

Local energy costs of 16.6 euro cents per kilowatt hour (kWh) are just a little more than half of the 27-30 cents Germans pay on average …

Feldheim’s rates are not far off those in Poland, which generates nearly all its electricity from carbon-intensive coal-fired plants.  Households there paid on average 14 cents per kWh in 2012, while those in the Czech Republic, which relies on nuclear for about a third of its power generation, paid about 15 cents per kWh.

DT:  Current electricity pricing in Canada is 6.3 to 11.8 cents/kWh (US$) & United States is 8 to 17 cents/kWh (US$) ~ wiki

Novel Active Energy Material Combines Solar Energy Generation and Power Storage

See on Scoop.itGreen Energy Technologies & Development

Premier Global – DayStar Technologies, Inc. Premier Global Holdings announced that it has demonstrated an active energy material that is the first to combine solar energy generation and power storage into one cell at the molecular level.

Duane Tilden‘s insight:

Laboratory tests validated energy storage capacity exceeding 26 hours, zero degradation and a road map for significantly longer storage times with additional optimization. It is believed that this is the first time sunlight has been captured and simultaneously stored in a highly efficient, low-cost format.

This technology was developed at the University of British Columbia (UBC) and addresses the natural intermittency associated with sun and cloud cover thereby making solar power available anytime day or night. The home is only one application as the technology naturally lends itself as a built-in solution for anyone who uses electricity — including those 1.6 billion without electricity in the remote regions of China, India and Africa.

Revolutionary Green Energy Storage Technology Issued Australian Patent

See on Scoop.itGreen Energy Technologies & Development

Texzon Utilities announces 4th patent for Invention that stores AC power as real AC power, making it the first and only AC battery.

Duane Tilden‘s insight:

“This technology is a game-changer. The ability of the RPM to clean (get rid of all harmonics), magnify power, and store energy as a traveling electro-magnetic wave enables it to react instantaneously as a continuous “elastic reservoir,” which is an innovative and timely solution for Smart Grids,” said General Mike Miller, CEO of Texzon.

About James Corum, Inventor:
Dr. Corum was cited as a “National Treasure” by The Office of the US Secretary of Defense for his work on the DARPA National Panel of Radar Experts on Ultra-Wideband Radar and Phenomenology. His electromagnetic research has been recognized by prestigious scientific organizations and professional societies around the world.

Is IT an Agent of Mass Extinction?

See on Scoop.itGreen Energy Technologies & Development

Enterprise architecture that automated decades ago must deal with new requirements and manage existing complexity, or face extinction

Duane Tilden‘s insight:

One of the first aspects of complexity in mature enterprises that comes to mind is what philosopher R. G. Collingwood called “the law of primitive survivals.” This states that earlier, more primitive forms of things coexist with later, more sophisticated forms of things. We see this in biology, where primitive forms, like sharks, exist with modern forms, like bony fishes, and algae coexist with flowering plants. The primitive coexists with the modern to a surprising extent. …

What is Complexity?

The complexity of information, technology and application architectures in mature enterprises seems to take the form of the survival of previous generations of environments integrated with overlays of more modern generations. …

Evolution and Extinction

Large, mature enterprises have seen mainframes, PCs, distributed processing, the Internet, the cloud and are now in the early stages of another revolution: big data. How much more complexity can be added to their environments? I have tried looking for answers in evolutionary science, which I studied at university; the field teaches that specialization typically leads to the inability to adapt to changing circumstances. …

Renewable Energy Generation Ltd. : Oil’s well that ends well in Warwickshire | 4-Traders

Oil’s well that ends well in Warwickshire

Warwickshire residents are being urged to do something good for the environment and help reduce weighty water… | March 26, 2013

Duane Tilden‘s insight:

An estimated £15 million per year is spent on cleaning blockages caused by ‘fatbergs’ – large masses of fat and grease that build up through disposal of used cooking oil down drains. If sent to landfill, oils often leak, polluting local watercourses and harming wildlife.

 

But thanks to a scheme run by Warwickshire County Council, residents are able to recycle their waste oil at specially placed tanks, located at six of the county’s household waste recycling centres (Cherry Orchard in Kenilworth, Stockton, Bruton Farm in Stratford, Princes Drive in Leamington Spa, Hunters Lane in Rugby and Judkins in Nuneaton). All oil collected is recovered through a completely natural process into renewable electricity for UK homes and businesses.

Imagining the Supergrid: HVDC Loops for High Penetration of Renewable Energy | The Energy Collective

See on Scoop.itGreen Energy Technologies & Development

The piecemeal way that the grid is being reinforced today is not compatible with a future supergrid incorporating renewable energy sources. This post examines an alternative layout for new HVDC connections for a future supergrid.

Duane Tilden‘s insight:

The case for a supergrid is very sensibly made by several organizations, …

GW must be transmitted thousands of km) so that the aggregate reliability of wind and solar are greatly improved, because generators in different weather regions can share capacity.

Since weather systems are typically ~ 2500 km (~1500 miles) across, the supergrid does not begin to fulfill its potential until it is quite large, after many billions of dollars have been invested.

This factor is very much holding up practical movement towards a supergrid, and what we are currently getting instead is a patchwork of transmission upgrades that are economically inefficient point-to-point connections that will not later fit in as components of a future supergrid. …

Environmental Protection – Landfill Gas Management Regulation

See on Scoop.itGreen Energy Technologies & Development

Duane Tilden‘s insight:

The regulation requires that municipal solid waste landfills with 100,000 tonnes or more of waste in place or with an annual waste acceptance rate exceeding 10,000 tonnes to undertake an assessment of landfill gas generation and to submit the results to the Ministry in a report by January 1, 2011.  […]

If according to Landfill Gas Generation Assessment Procedure a regulated landfill site is estimated to generate 1000 tonnes or more of methane, the owner or operator of that site is required to complete a LFG management facilities design plan and to install the designed facilities at the landfill site.  The Landfill Gas Management Facilities Design Guidelines (PDF/9.3 MB)  […]  The performance standards prescribed in the document are intended to implement high-efficiency LFG collection systems. This Guideline must be used by landfill owners, operators, and qualified professionals in the preparation of LFG facilities design in accordance with the Landfill Gas Management Regulation.
