Energising Money

Energising Money | Sustain Our Earth | Scoop.it

"Our economic system fails to properly account for the natural resources on which human prosperity depends. But attempts to remedy the problem, for example through environmental taxation, fail to address an elephant lurking in the room: the monetary system. Energy-related money offers a means to improve the qualities of the monetary system, while also stimulating the low-carbon energy transition we urgently need."

Smart Grid and Energy Storage Installations Rising Worldwide

Smart Grid and Energy Storage Installations Rising Worldwide | Sustain Our Earth | Scoop.it

"Global investment in smart grid technologies rose 7 percent in 2012 from the previous year. On top of direct investments, numerous countries around the world are making headway on smart grid regulatory policies, development plans, and frameworks to support future grid infrastructure upgrades.  Smart grids consist of many different technologies serving different functions. Smart grids are commonly defined as an electricity network that uses digital information and communications technology to improve the efficiency and reliability of electricity transport."

Norm Miller's comment, March 3, 2013 10:52 AM
For smart grids to really work we need ways to store energy more efficiently, i.e. better batteries. When will large scale better batteries become available? What's on the horizon for energy storage?
Joan Tarruell's comment, March 3, 2013 11:34 AM
Another possibility is to use the energy generated by instantaneous sources (wind, sun, waves) before origins occurring storable (gas, coal, water reservoirs, etc.)

Direct action has its place in all movements.  Sea Shepherd and Paul have always pushed the line.  Most recently that has led to Paul fleeing Germany and becoing a bail jumper and now the U.S. Courts ruling the Austrailan branch to be "pirates."  That maybe true, but I wonder why the Japanese Whalers are not similarly labeled?

UN says fertiliser crisis is damaging the planet ("Why not focus on mass organic waste conversion?")

UN says fertiliser crisis is damaging the planet ("Why not focus on mass organic waste conversion?") | Sustain Our Earth | Scoop.it
The world is facing a fertiliser crisis, with far too little in some places, and far too much in others, a new report from the United Nations says today.

The mass application of nitrogen, phosphorus and other nutrients needed for plant growth has had huge benefits for world food and energy production, but it has also caused a web of water and air pollution that is damaging human health, causing toxic algal blooms, killing fish, threatening sensitive ecosystems and contributing to climate change, says the report, “Our Nutrient World”.

However, in some parts of the world, insufficient access to fertilisers remains the problem, and still hampers food production and contributes to land degradation – even while supplies of some nutrients such as phosphorus are more and more seen to be limited.

The report calls for a major global rethink in how fertilisers are used across the world, so that more food and energy can be produced while pollution is lessened rather than increased.
