#Organic framework serves as catalyst for the photocatalytic conversion of water into hydrogen Humanity's need for energy is ever-increasing.
However, the traditional energy sources are finite. In contrast, water and sunlight are available in vast abundance.
Scientists at the Max Planck Institute for Solid State Research in Stuttgart and from LMU Munich have created now a material that uses light to produce the versatile energy source hydrogen from water.
What is needed is a substance that directly uses the energy of sunlight to split the hydrogen-oxygen bonds in water.

"Microwave energy is more efficient than conventional heating because it focuses its electromagnetic waves only on the material being treated
or lithium-air, batteries have been touted as the'ultimate'battery due to their theoretical energy density, which is ten times that of a lithium-ion battery.
Such a high energy density would be comparable to that of gasoline -and would enable an electric car with a battery that is a fifth the cost and a fifth the weight of those currently on the market to drive from London to Edinburgh on a single charge.
and lithium-air batteries are considered the ultimate in next-generation energy storage, because of their extremely high energy density.
Finally, that nitrogen lowered the energy needed to kick electrons into the state in which they were available to split water.
Conceptually, all of the energy produced could be stored indefinitely and used later when the electricity is needed most.
Alternatively, some energy could be used immediately and the rest stored for later use. Storage of this type helps to solve one of the key factors limiting the wider use of solar energyy eliminating the need to use the electricity immediately.
Many alternative energy systems are constrained by this lack of dependability and consistent energy flow. Solar thermal electricity has been of considerable interest because of its potential to lower costs.
In contrast to conventional solar photovoltaic cells that produce electricity directly from sunlight, solar thermal generation of energy is developed as a large power plant in

#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,

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,
