Evaluation of 3D printed optofluidic smart glass prototypes...Smart glass or smart windows are an innovative technology used for thermal management,energy efficiency,and privacy applications.Notable commercially available smart glass relies on an electric stimuli to modulate the glass from a transparent to a translucent mode of operation.However,the current market technologies,such as electrochromic,polymer dispersed liquid crystal,and suspended particle devices are expensive and suffer from solar absorption, poor transmittance modulation,and in some cases,continuous power consumption.The authors of this paper present a novel optofluidic smart glass prototype capable of modulating visible light transmittance from 8% to 85%. #optofluidic #smart_glass 3D_PRINT #OPTICS #PHYSICS (...)

Almost three-quarters of new ships carrying consumer goods already exceed IMO’s post-2025 energy efficiency requirement – new study

Almost three-quarters (71%) of all new containerships, which emit around a quarter of global ship #CO2 emissions, already comply with the post-2025 requirements of the IMO’s Energy Efficiency Design Index (EEDI), a new study reveals. Additionally, the best 10% of new containerships are already almost twice as efficient as the requirement for 10 years time. These findings are part of a study based on analysis of the International Maritime Organisation’s (IMO) own data and conducted by Transport & Environment (T&E), a founding member of the Clean Shipping Coalition (CSC).

Norway’s push for Arctic oil and gas threatens Paris climate goals – study | Environment | The Guardian

▻https://www.theguardian.com/environment/2017/aug/10/norways-push-for-arctic-oil-and-gas-threatens-paris-climate-goals-study

[...]

They focussed on Norway because it has long been a supporter of ambitious global reduction targets and has used part of its oil revenues to develop renewable technologies and tackle deforestation. If it cannot leave fossil fuels in the ground and make the transition to a carbon-free economy, the authors ask, then how can any of its rivals in less developed nations be expected to do so?

“This is uncharacteristically irrational behaviour for Norway,” said Hannah McKinnon of Oil Change International. “The Paris climate goals mean the world has to stay within a finite carbon budget. Norway’s current plans for fossil fuel production, expansion, and exploration are dangerously out of line with these budgets. Norway can’t be a climate leader at the same time as depending on new oil and gas production.”

The government says such accusations are unfair because they run against the convention at international climate talks for the responsibility for emissions to lie with consumers rather than producers. In this regard – of purely domestic carbon use – it is doing better than most nations because it gets 97% of its electricity from renewable sources, has a high carbon tax, is a leader in promotion of electric vehicles, and is pioneering carbon capture and storage at waste plants and cement factories.

It also notes that oil and gas output is flat, it is unrealistic to assume that all exploration will be successful and the trend for overall production is away from carbon-heavy oil and towards cleaner gas, which is important as a “transition fuel” for countries that are trying to move away from coal. Officials point out that without Norway’s gas the UK would be far further behind in meeting its climate goals.

“We are part of the solution, not the problem,” the deputy minister for petroleum and energy, Ingvil Smines Tybring-Gjedde, told the Guardian. “This government is investing more in renewables and energy efficiency than any other. But renewables are not yet at a level where we can switch off oil and gas. We need a bridge.”

The government argues that its oil and gas reserves are the most efficiently extracted in the world and that, so as long as there is demand for these fuels, it is better that they come from Norway. It also puts the number of newly offered exploration blocks closer to 50.

European power is slipping away from King Coal - Climate News Network

▻http://www.climatenewsnetwork.net/european-power-is-slipping-away-from-king-coal

By Alex Kirby

Analysis of falling demand for electricity within the EU sends a stark warning to investors in new coal plants that their assets could be left stranded.

LONDON, 10 June, 2015 − Coal, the muscle that for two centuries powered Europe’s economic dominance of the world, is steadily losing its grip as cleaner fuels take its place and energy efficiency cuts electricity consumption, according to new analysis.

The European Union’s electricity demand fell by 3.3% from 2008 to 2013 − even though GDP grew by 4.1% − and the analysts say changing market conditions for utilities leaves new coal plants failing to generate positive cash-flows even in the most optimistic scenario.

Financing universal health coverage by cutting fossil fuel subsidies - The Lancet Global Health
▻http://www.thelancet.com/journals/langlo/article/PIIS2214-109X(15)00007-8/fulltext

Worldwide, nearly half a trillion dollars were spent on fossil fuel subsidies in 2010.1 Although these subsidies were at first intended to protect poor people from high fuel costs, in practice they are more likely to benefit wealthy households, promote overconsumption of fuel, and discourage energy efficiency.

(...) Abolishment of fuel subsidies, however, is often difficult to pursue because of public opposition. Indeed some attempts to reduce fuel subsidies, such as those in Nigeria,4 Indonesia,5 and Sudan,6 have been met with violent protests. The perceived benefits of fossil fuel subsidies are apparent in daily life, and their removal is felt abruptly and immediately

(...) Rapid health-care reforms, however, have been shown to deliver tangible benefits to the population relatively quickly.7

Drilling surprise opens door to volcano-powered electricity
▻https://theconversation.com/drilling-surprise-opens-door-to-volcano-powered-electricity-22515

Elders said that the success of the drilling was “amazing, to say the least”, adding: “This could lead to a revolution in the energy efficiency of high-temperature geothermal projects in the future.”

The well funnelled superheated, high-pressure steam for months at temperatures of over 450°C – a world record. In comparison, geothermal resources in the UK rarely reach higher than around 60-80°C.

The magma-heated steam was measured to be capable of generating 36MW of electrical power. While relatively modest compared to a typical 660MW coal-fired power station, this is considerably more than the 1-3MW of an average wind turbine, and more than half of the Krafla plant’s current 60MW output.

[...] With the deeper boreholes, the IDDP are looking for a further prize: supercritical water; at high temperature and under high pressure deep underground, the water enters a supercritical state, when it is neither gas nor liquid. In this state it carries far more energy and, harnessed correctly, this can increase the power output above ground tenfold, from 5MW to 50MW.

EU Light-Bulb Ban Illuminates Power Struggle in Brussels - Spiegel Online
►http://www.spiegel.de/international/europe/eu-light-bulb-ban-illuminates-power-struggle-in-brussels-a-852931.html

celle-ci est pas mal ; la politique de l’#Union_européenne visant à éliminer les ampoules à incandescence prouve qu’il s’agit d’une #dictature (verte) :

Nowhere is the bureaucratic influence of European government agencies as powerful as in the delirium of energy efficiency.

“The EU has made a decision without consulting citizens and, in doing so, it has massively intervened in our quality of life,” says Hannot, the light-bulb activist. This paternalism and lack of transparency almost aggravates him more than doing without the stronger, warmer light of incandescent light bulbs. The makers of the documentary film “Bulb Fiction” even speculate that the European light-bulb lobby, including major companies like Philips and Osram, are behind the demise of the cheaper incandescent light bulb given the much larger profit margins associated with more expensive energy-saving light bulbs.

Leaked documents reveal UK fight to dilute EU green energy targets (The Guardian)

The government has been trying to water down key environmental regulations in Brussels despite trumpeting its commitment to green issues at home, leaked documents show. The papers, seen by the Guardian, reveal British officials repeatedly trying to prevent the adoption of European Union rules on energy efficiency, curtailing the proposals and making them voluntary rather than mandatory in many cases. In addition, the UK has tried repeatedly to ensure that the EU does not adopt a new target for renewable energy generation. (...) Source: The Guardian

Smart Meter, Big Brother

The goal of smart meter technology is to improve energy efficiency, cut greenhouse gases and save consumers money. But Kevin Doran, a Senior Research Professor at the University of Colorado, tells host Bruce Gellerman that these smart meters raise privacy concerns because they can potentially reveal personal details about customers’ at-home behaviors.
