#New zealand will shut down its last large coal fired power generators in 2018 New zealand electricity company Genesis Energy has announced that it will shut down its last two coal fired power generators by December 2018-a bold step towards the country
"the Energy and Resources Minister Simon Bridges said in a press release. Because the majority of New zealand's energy already comes from geothermal, hydro,
and natural gas, giving up coal isn't as big a deal as it would be for other countries(*cough*Australia, the United states*cough),
"What's really cool is that the decision was made by Genesis Energy solely on the basis of profits,
In fact, Genesis Energy Chief executive Albert Brantley estimated in a press release that the company will save around NZ$20 to 25 million (US$13 to 16.5 million) each year by not running the coal fired generators.
The two remaining coal-burning generators are located at Genesis Energy's Huntly Power station in Waikato on the country's North Island.
which gave rise to the very high electric field necessary to generate a long-term and dense plasma with little energy.
Success in the field of artificial photosynthesis normally means achieving an energy efficiency of above 10 percent.
Hydrogen could even be used as an inexpensive energy storage technology at the household level to store energy from rooftop solar cells.
The primary benefit is lower power consumption. Whereas Bluetooth devices worn on the body transmit data via radio signals,
and this allows the energy to be captured more efficiently.""The trick in getting them to be nearly transparent is in making them really thin-the electrodes are just 80 nm

#London is now recycling energy from train brakes to power their stations London has just finished testing a new system that can collect

The city reports that it already shaving 5 percent off the annual energy bill which might not sound like much,
"The trial puts London at the cutting edge of this kind of technology and clearly demonstrates how energy from trains can be recovered to power Tube stations,
Deputy Mayor for Environment and Energy, said in a press statement.""This complements our wider work to make other forms of public transport cleaner
The system works by collecting energy generated by the trains when they brake before feeding it back into the power mains as electricity."
According to the London transport authority, it collected an average of 1 Megawatt hour (MWH) of energy each day,
Another benefit of the inverter system is that by collecting up the energy and turning it into electricity

and discharging energy, Yao said. The discovery could lead to a cheaper alternative to traditional inorganic-based energy devices,
including lithium batteries. Ultimately Yao said, it could translate into less expensive consumer devices and even less expensive electric cars.
Yao's research group focuses on green and sustainable organic materials for energy generation and storage.
and energy storage devices are expensive partly because the materials used to make them, including cobalt and silicon-based compounds,
require huge energy expenditures to process. Organic polymers can be processed at relatively low temperatures, lowering the cost.
"Organic-conjugated polymers are emerging as a materials class for energy-related applications, enabling a path to a more sustainable energy landscape without the need of energy-intensive, expensive and sometimes toxic metal-based compounds,
"the researchers wrote, concluding that"a model polymer, P (NDI2OD-T2), was stably and reversibly n-doped to a high doping level of 2. 0,
and see widespread applications, especially in energy-related ones such as batteries, supercapacitors and thermoelectrics.""The basic polymer used in the work was discovered in 2009;
Conventional inorganic batteries still are capable of holding more energy than the organic battery, and Yao said work will continue to improve the storage capacity of the material.
The batteries can have three times the energy density of lithium-ion batteries, but have been sluggish. To counter that problem,

--while using only 1 percent of the energy. The new"out-of-oven"approach may offer a more direct
energy saving method for manufacturing virtually any industrial composite, says Brian L. Wardle, an associate professor of aeronautics and astronautics at MIT."
The team measured the energy required to solidify or cross-link, the polymer and carbon fiber layers, finding that the CNT film used one-hundredth the electricity required for traditional oven-based methods to cure the composite.
Thus, the energy absorbed from light is efficiently and rapidly converted into electron heat. Next, the electron heat is converted into a voltage at the interface of two graphene regions with different doping.

A large portion of the energy used in computing is spent on transferring data from one type of memory to another.
Doing that quickly takes more energy and generates more heat. In past research Salahuddin and his colleagues found that directing electrical current through the rare metal tantalum creates polarity in magnets without an external magnetic field.

in order to reduce power consumption when transmitting and receiving information, wireless systems need to send signals that can easily travel from one side of the human body to another.
so signals are communicated with much lower path losses and potentially, much lower power consumption. In their experiments, researchers demonstrated that the magnetic communication link works well on the body,

#Loss of cellular energy leads to neuronal dysfunction in neurodegenerative disease model A new study from the Gladstone Institutes shows for the first time that impairments in mitochondria--the brain's cellular power plants--can deplete cellular energy levels
A link between mitochondria, energy failure, and neurodegeneration has long been hypothesized. However, no previous studies were able to comprehensively investigate the connection because sufficiently sensitive tests,
the scientists created novel assays to more accurately measure the brain's energy production. Using a model of Leigh's disease,
the researchers tested energy levels in neurons using the new assays. They found that the genetic mutation associated with Leigh's disease compromised ATP levels,

so that the cells had to rely solely on their mitochondria for energy. This allowed the researchers to more accurately assess the contribution of mitochondrial ATP to different steps in the cycle,
From this exploration, the scientists revealed that bringing the vesicles back up into the cell after they have released their neurotransmitters is the most energy-demanding process.
The researchers also compared energy levels in boutons--the docks from which neurotransmitters are shipped--with and without mitochondria.
Remarkably, there was no difference in energy levels between the two, and both types of boutons had sufficient ATP to support synaptic vesicle cycling.
so that even those boutons lacking mitochondria have sufficient energy to function under normal conditions. They note it will be important to determine
