The EU energy package has officially come into force with two Directives and three Regulations aimed at creating an integrated Europe-wide energy market that will drive the first steps toward a smart grid. The gas and electricity market Directives require that EU member states implement "intelligent metering systems that shall assist the active participation of consumers". By 2020, the Directive targets that 80% of households in Europe should be equipped with smart electricity meters and that a complete rollout should be achieved by 2022.

This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

""NEMA thanks Representatives Ellmers and McNerney for their leadership in introducing HR 2244, and we appreciate the support from Energy and Commerce Committee Chairman Fred Upton and Energy and Power Subcommittee Chairman Ed Whitfield for including it in their grid modernization discussion draft. This much-needed legislation would direct the Department of Energy to produce a plan to create a strategic transformer reserve program, an idea supported by NEMA and its members as a way to bolster the United States' capacity to respond quickly to the loss of one or multiple large power transformers," "

"As a storm raged over the government's directive to the Clean Energy Finance Corporation to no longer back wind energy projects, it emerged that it has also put a stop to solar investments other than the largest industrial-scale projects."

"For remote charging to take off metaphorically as well as literally, though, devices employing it need to be interoperable. That means establishing industry standards. Unfortunately, in a competition reminiscent of that in the 1890s between alternating current (Tesla's preference) and direct current (promoted by Thomas Edison), three main consumer standards have emerged."

"Centuries ago, Nikola Tesla envisioned and pioneered the concept of wirelessly transmitting power over long distances through the Earth's ionosphere. In the recent past, wireless energy transfer has occurred by way of an electromagnetic (EM) field set to a certain frequency level. While transmission efficiency over longer distances is attained to an extent by this method, it becomes increasingly difficult when complicated pointing and tracking mechanisms are mandatory to maintain the right wavelength between the transmitter and the receiver. Another drawback to this approach is that any object that falls between the transmitter and the receiver impedes the beam, thus interrupting power transmission to a potentially harmful degree if the power level goes beyond a certain threshold point. Even though microwave frequencies could prove effective to transmit power over long distances through a radiated EM field, the aforementioned caveats still apply. The other possible way to wirelessly transmit power is by non-radiative fields. For instance, a transformer operates by magnetic induction drawing similarities to wireless power transfer. Energy transfer in a transformer happens from the primary coil to a secondary coil in the absence of a direct electrical connection. The same approach can be seen in inductive chargers found in electric toothbrushes, for example. However, for this functionality to operate smoothly, primary and secondary coils must be positioned in close proximity to one another."

Dwarfed by any of the north African nations, it represents an area slightly smaller than Wales but scientists claimed yesterday it could one day generate enough solar energy to supply all of Europe with clean electricity. Speaking at the Euroscience Open Forum in Barcelona, Arnulf Jaeger-Walden of the European commission's Institute for Energy, said it would require the capture of just 0.3% The scientists are calling for the creation of a series of huge solar farms - producing electricity either through photovoltaic cells, or by concentrating the sun's heat to boil water and drive turbines - as part of a plan to share Europe's renewable energy resources across the continent. A new supergrid, transmitting electricity along high voltage direct current cables would allow countries such as the UK and Denmark ultimately to export wind energy at times of surplus supply, as well as import from other green sources such as geothermal power in Iceland. Energy losses on DC lines are far lower than on the traditional AC ones, which make transmission of energy over long distances uneconomic. The grid proposal, which has won political support from both Nicholas Sarkozy and Gordon Brown, answers the perennial criticism that renewable power will never be economic because the weather is not sufficiently predictable. Its supporters argue that even if the wind is not blowing hard enough in the North Sea, it will be blowing somewhere else in Europe, or the sun will be shining on a solar farm somewhere.

Aluminum may have been responding to two different events in the week ending July 11 when it hit a succession of all-time price highs , but the market remains divided over the medium-term direction, given that world fundamentals point to weak demand and rising stock levels. \n\nFundamentally, however, analysts and market players were mixed in their impressions of whether the price could be sustained, especially as word emerged from China that the cuts may not be a certainty. \n\nAluminum finished floor trade for the week at $3,318/mt, up $150 from the July 4 closing price of $3,168. Fundamentally, however, analysts and market players were mixed in their impressions of whether the price could be sustained, especially as word emerged from China that the cuts may not be a certainty. \n\nPointed out a US broker, "When you hear producers [in China] are shutting production because demand is weak, that's normally bearish," yet the market saw "insane" price moves. "I hear metal just continues to pour into warehouses, and not all of it reported, obviously, [since] otherwise you'd see it in the stock numbers. A lot is going off warrant," he pointed out. \n\n\n

Mongolia's political parties are locked in post-election squabbling, but once the dust settles a new government could finally pass deals to tap the coal, copper and uranium that sit beneath its vast deserts and grasslands. But analysts say the deal that goes ahead would be less than ideal for either Mongolia or foreign investors, with the country better served by taxing its mineral wealth, rather than seeking direct government ownership in massive mines. The current law gives the state either a 34% stake or a controlling 51 percent stake in mining projects. An investment agreement with Ivanhoe Mines and Rio Tinto for the Oyu Tolgoi project, still under negotiation, would be the first such deal.

Hydrogen fuel-cell cars have received a great deal of attention over the years as a clean alternative to petroleum-based transportation, producing only water for exhaust. Certainly the technology is known. Demonstration vehicles have been produced by several manufacturers and Honda is starting to roll out a fleet of 200 FCX Clarity fuel-cell cars, available for lease to select customers for US $600 per month. These autos are costing Honda hundreds of thousands of dollars each though, according to Honda's president Takeo Fukui (Wall Street Journal, June 16 2008), and it will take another decade before their cost falls below US $100,000. Although fuel-cell cars remain a long way from providing commercially viable transportation for the vast majority of people, cars are not the only application for fuel cells. Fuel cells are reaching commercial viability sooner in other applications such as portable electronics, including laptops, cell phones, MP3 players and games, aiming to supplement the ability of batteries to power these mobile devices for extended periods of time. There are a number of reasons why fuel cells may prove more competitive in portable electronics than in cars, including the favorable cost, lifetime requirement and easier distribution in this market. One of the companies developing fuel-cell technology for portable electronics is Polyfuel, using its proprietary hydrocarbon membrane technology for direct methanol fuel cells. The cost of power for portable electronics, according to Polyfuel president and CEO Jim Balcom, is up to US $10,000 per watt, compared with US $20-50 for autos, making portable electronics a much more attractive market than cars initially.

Long ago, the industry determined that the combination of copper tubing and aluminum fins provided the most efficient transfer of thermal heat in condenser coils. Manufacturers of residential units are not necessarily on that same page - or that line of thinking - today. Most manufacturers, if not all, are revising, have revised, or continue to revise their outdoor coil construction. One of the main objectives, of course, is to increase heat transfer efficiency, as energy efficiency is high on every homeowner's wish list. In the end, each manufacturer believes it has engineered and/or perfected - at least up to now - the most-efficient coil design. Some, like Goodman Manufacturing, have made changes as a direct result of the efficiency offered from R-410A refrigerant.

Greenbang went down to Kyocera's Green Card event earlier this year to hook up with Adrian Harding of the Environment Agency - he told us what's happening with the Waste Electrical and Electronic Equipment Directive… Check him out on this film…

The European Union (EU) adopted a directive in late October that will place a cap on greenhouse gas emissions from all flights arriving at or departing from EU airports, starting in 2012.

Could this cap underpin a drive toward lightweighting in aviation?

Driven by technological advances in powder metals (P/M) forging, spray forming, hot isostatic pressing, direct powder rolling, high temperature vacuum sintering and metal injection molding, the world metal powders market is projected to reach $5.7 billion by the year 2012. Growing popularity in the use of new equipment components made from powered metallurgy in industries such as electronics, aerospace, automobile, and mechanical engineering, is expected to offer expanded market opportunities for future growth.
