This energy is transferred then into a working fluid which creates steam, which replaces electricity in order to power mechanisms or generators.

#Graphene Heating system Dramatically Reduces Home energy Costs Breakthroughs in energy generation using nanomaterialsike their enabling of better supercapacitors
But it is unheralded in the area of energy savings that nanomaterials are perhaps making the biggest inroads.
A startup in the UK called Xefro is bridging this divide between energy generation and energy savings through its development of a heating system that the company claims marks the first time that the onder materialgraphene has been used as a heating element.
Depending on the kind of heating system currently used in a home the company estimates that this graphene-based heating system can reduce energy costs by anywhere from 25 to 70 percent.
Xefro uses graphene-based ink that can be printed on a variety of materials and into just about any configuration.
and leverages graphene large surface area so that energy isn wasted in heating up the heater itself. he innovation is all about getting useable heat where it is needed,
placing the heating element inside a metal box that reflects back most of the infrared energy,
and ensure that most of the heat is emitted out into the room rather than simply heating up the wall behind the heater. hile graphene does offer some attractive properties for reducing wasted energy,
says Harper. he energy savings come when the heaters are deployed as a system throughout a building. The heaters are linked with the control system via Wi-fi,

Keuka Energy recently launched a 125-kilowatt prototype vessel that uses its novel floating wind turbine design paired with liquid-air energy storage to create a steady source of electricity.
When the energy is needed, the liquid air is pumped to a high level of pressure and heated to a gas state.
Although it is an attractive energy storage technology because of its long duration, liquid-air energy storage requires a significant amount of electricity to make the liquid air,
a U k. startup that makes utility-scale liquid-air energy storage systems. Another similar technology that has gained more traction is compressed-air energy storage
which does not have the energy density of liquid air, but so far has proven more cost effective.
Other startups are also looking offshore for cheap energy storage. Bright Energy is developing a system that would use offshore renewable energy to store compressed air in vessels in the ocean.
Canadian startup Hydrostor also has a design to store compressed air underwater. If Keuka 125-kilowatt prototype is successful,

#Lessons From ESOS Energy Legislation In The UK The U k. recently announced compliance guidelines for the government new Energy savings Opportunity Scheme (ESOS), a mandatory energy assessment and energy saving identification
scheme in response to the requirement or all Member States of the European union to implement Article 8 of the Energy efficiency Directive.
The objective of ESOS is to reduce energy consumption, help address climate change, increase energy security and improve the competitiveness of U k. businesses.
and administered by the Environment Agency intended to trim excessive energy use as a means to cut carbon
while mitigating organizational energy waste. In short but not-so-simple terms, qualifying businesses are required to a) measure total energy consumption, accounting for 90 percent of usage across all buildings, transport and industrial activities;
b) conduct energy audits to identify cost-effective, energy-efficient recommendations; c) ensure that the ESOS assessment has been conducted
or reviewed by a board-level director and approved by a lead assessor; and d) report compliance to the Environment Agency by December 5, 2015.
certain caveats exists there is no obligation to implement these energy saving measures internally identified in the audit,
Though the legislation notable feature appears spineless by failing to require businesses make any of these recommended changes to save energy,
participants must demonstrate an authentic and rigorous attempt to examine opportunities for reducing energy use and have reviewed these findings at the board level.
The Challenge to Measure and the Burden of proof While companies may find motivation for implementing the recommended energy saving measures of the audit solely for financial benefit,
the ESOS directive is as much about enforcement as it is about the need for companies to understand power consumption.
Uncovering pockets of energy waste requires appointing personnel familiar with the scheme; the only other option is to outsource,
the vast majority of businesses lack the technology to accurately track such energy consumption. Measuring the energy consumption of a Macbook Air compared to that of a Dell Desktop PC,
for example, will prove to be difficult. While some organizations already have the Microsoft System Center Configuration Manager (SCCM) in place
allows companies to reference the power consumption of each device, along with the actual power usage when on and off.
taking into consideration that the U s. wastes an approximate $2. 8 billion in PC energy every year, the U k. may need to take a more effective approach to energy security.
Recognizing the additional administrative pressure placed on energy managers with ESOS which will have many similarities to existing U k. policies the government is proposing that enterprises be allowed to utilize data from other schemes,
such as the Carbon Reduction Commitment (CRC) Energy efficiency Scheme. Of the 7, 000-plus businesses required to participate, as many as 6,
Although energy efficiency in the U s. has been a buzzword for years, when it comes down to it,
According to the American Council for an Energy-efficient Economy, even China and India have fared better on the list than the U s as American energy regulations for power conservation have been particularly scarce in recent years.
Although the Obama administration and the now Republican-dominant Congress continue to be at odds over legislation that not only addresses energy efficiency
Ideally, a partnership between U s. government and industry is essential for an energy policy to have a significant impact on the future of businesses and the environment.
The state-by-state approach indicates great strides in U s. energy efficiency and environmental stewardship, but at what cost to businesses?
As the U s. continues to rank among the top three energy consumers in the world,

#Blame the Weather for Last Year s Rise in U s. Carbon dioxide emissions A colder winter was one of the main reasons carbon dioxide emissions from energy use rose in the United states by 2. 5 percent in 2013
, according to new data from the Energy Information Agency. Besides a small rise in the price of natural gas and slightly cheaper coal, the weather played the biggest role in in pushing up emissions,
there were 18 percent more days in 2013 cold enough to cause a spike in demand for energy for heating,
This contributed to an 0. 5 percent increase in the amount of energy used per dollar of GDP,
More coal and less gas meant a much smaller drop in the U s. energy system arbon intensity?

and efficiently converts the energy in sunlight into hydrogen, which can be used as a fuel
The solar water splitter stores 12.3 percent of the energy in sunlight in the form of hydrogen.
but consider that most solar cells convert only 16 percent of the energy in sunlight into electricity,
without the added step of turning that energy into easy-to-store hydrogen. More work is needed before the device can be practical.

#Germany and Canada Are Building Water Splitters to Store Energy Germany which has come to rely heavily on wind

It can be deployed almost anywhere it can store vast amounts of energy and the hydrogen can be used to replace fossil fuels not only in electricity production but also in industry and transportation
Even so it has long been considered a relatively lousy way to store energy because of its low efficiency about 65 percent of the energy in the original electricity is lost.
