Renewables Super Grid Proposed to Solve Europe's Energy Dilemma
Renewables super grid proposed to solve Europe’s energy dilemma A pan-European electricity system powered by decentralised renewable energy supply and connected across a high-volume super grid has been described as the least-cost option to provide an optimal pathway to achieving the goals of the Paris Agreement while at the same time solving key obstacles towards developing a functional European Energy Union. Researchers from Lappeenranta University of Technology (LUT) in Finland have for several years now been developing 100 per cent renewable energy super grid models for global regions, and in 2016 even developed a first-of-its-kind planetary renewable energy model. Further, in November 2017, on the sidelines of the United Nations Climate Change Conference COP23 in Bonn, Germany, LUT researchers showcased how a 100% global renewable energy grid is not only a viable option but the most cost-effective option. Focusing their attention on the European Union, LUT researchers recently published an article in the journal Renewable Energy entitled Flexible electricity generation, grid exchange and storage for the transition to a 100% renewable energy system in Europewhich reveals the results of two scenarios: the first depicts a scenario made up of 20 European regions acting as independent energy “islands”; the second scenario depicts those same 20 regions connected through a pan-European super grid. This second option, labelled as a “SuperSmart” energy system – as it acts as a compromise between two European Energy Union approaches that have been floated in recent years; a decentralised renewable energy Smart Grid approach, and a centralised and regulated Super Grid – would utilise decentralised renewable energy generation across the European Union combined with a super grid to facilitate pan-European energy trade. -

Japan in the Era of Connectivity
CRS Seminar Series Japan in the Era of Connectivity Date: Wednesday, March 7, 2018 Time: 16:00-17:30 Venue: Conference room, Center for Rule-making Strategies (5th Floor, Shinagawa Intercity Front, 2-14-14 Kōnan, Minato-ku) Language: English CRS cordially invites you to attend a seminar by Dr. Parag Khanna, the author of Connectography: Mapping the Future of Global Civilization (Random House, 2016). In this seminar, Dr. Khanna will give a talk titled “Japan in the Era of Connectivity,” where he will give us his take on Japan’s place in the world where strategic importance of a country is measured by connectivity – global transportation, communications, and energy infrastructures - rather than traditional population or size. The talk will be followed by a Q&A session with the audience. Please contact [email protected] to register for the event. Speaker Dr. Parag Khanna Global Strategist and best-selling author, The author or “Connectography” Parag Khanna is a leading global strategist, world traveler, and best-selling author.

Specifically, research in the MARS project is categorized into the following four sub-areas each of which contribute to the development of the integrated infrastructure. (1) Multimedia Content Representation: extraction of multimedia content and content-based representation of multimedia objects in databases. (2) Multimedia Information Retrieval: content-based multimedia retrieval techniques including multimedia retrieval models and interactive query refinement techniques. (3) Multimedia Feature Indexing: that overcomes the high-dimensionality and non-Euclidean nature of feature data to efficiently support retrieval based on feature similarity. (4) Multimedia Database Management: techniques to effectively and efficiently incorporate content-based retrieval of multimedia information into structured database processing. -

A Road Map to Deliver Smart Grid in the UK Simon Skillings
A Road Map to Deliver Smart Grid in the UK Simon Skillings Summary The concept of a ‘smart grid’ involves the combination of instrumentation, communications and analytics that allows power network infrastructure to be operated in a dynamic and efficient manner as opposed to the ‘passive’ operational approach which is currently the norm in the UK. There exists general consensus that the challenges of climate change and system security, in particular the ability to accommodate significant volumes of decentralised and renewable generation, requires that the network infrastructure must be upgraded to enable smart operation. Failure to do so will act as a major obstacle in the transition to a low carbon economy. A second important aspect of network development involves the construction of a number of strategic interconnections across the North Sea to create a new off-shore grid. This opens up the opportunity to more fully exploit the vast untapped potential of off-shore wind energy. However, there are a series of obstacles which have hitherto hindered progress in upgrading the network. In particular, the current regulatory regime is not well designed to encourage network operators to embrace new technological opportunities and this is exacerbated by the extent of the risk and uncertainty involved. The government has a key role to play in injecting the necessary momentum by providing strong direction to the regulator on the outcomes that must be delivered. In addition, the government needs to ensure the appropriate financing routes are in place that will enable Ofgem to set a regulatory framework that leads to a low cost of capital for investors whilst retaining the necessary management incentives on network operators to deliver the required outcomes. -

On the Legality of Mars Colonisation
Joshua Fitzmaurice* and Stacey Henderson** ON THE LEGALITY OF MARS COLONISATION ‘Humanity will not remain on the earth forever, but in pursuit of light and space it will at first timidly penetrate beyond the limits of the atmosphere, and then conquer all the space around the sun.’1 ABSTRACT Recent technological advancements made by governmental agencies and private industry have raised hopes for the future of human space flight beyond the Moon. These advancements are increasing the feasibil- ity of endeavours to establish a permanent human habitat on Mars, as a safeguard for our species, for scientific endeavours, and for commercial purposes. This article analyses some of the legal issues associated with Mars colonisation, focusing on the lawfulness of such a venture and the legal status of colonists.
