Some 365 giant wind turbines are to be installed in desert around Lake Turkana in northern Kenya – used as a backdrop for the film The Constant Gardener – creating the biggest windfarm on the continent. When complete in 2012, the £533m project will have a capacity of 300MW, a quarter of Kenya's current installed power and one of the highest proportions of wind energy to be fed in a national grid anywhere in the world. 

Designer Chiyu Chen has conceived of an ingenious transit system that encourages the use of sustainable transportation by crediting people for renting and riding bicycles. His Hybrid2 system consists of a fleet of rentable bicycles that are capable of generating and storing kinetic energy, which is then used to power the city’s hybrid electric buses. Simply rent a bike, charge it up with kinetic energy from pedal power, and then return it to a kiosk - the station feeds energy into the city’s smart grid, and you receive a credit towards your next bus pass!

On September 26, 2009, World Wide Views on Global Warming (WWViews) will give citizens all over the world a possibility to define and communicate their positions on issues and questions central to the negotiations at the United Nations Climate Change Conference (COP15) in Copenhagen, starting two months later.

BUILD UP is a new environment for building professionals, local authorities and building occupants willing to share their experience on how to cut energy consumption in buildings. Diversity is a major strength of the EU and BUILD UP will promote the exchange of all the best practices, tools and technologies available across Europe for an effective implementation of energy-saving measures in buildings. When it comes to climate change and security of energy supply, there is no easy fix. It is only by working together that we will achieve a real impact.

True or false: taking the commuter train across Boston results in lower greenhouse gas emissions than travelling the same distance in a jumbo jet. Perhaps surprisingly, the answer is false. A new study compares the "full life-cycle" emissions generated by 11 different modes of transportation in the US. Unlike previous studies on transport emissions, Mikhail Chester and Arpad Horvath of the University of California, Berkeley, looked beyond what is emitted by different types of car, train, bus or plane while their engines are running and includes emissions from building and maintaining the vehicles and their infrastructure, as well as generating the fuel to run them.

Fears over energy security and climate change have led to record investment in renewable energy. But a major problem threatens to stall progress towards a more sustainable future: national electricity grids are far from ready to cope with the variable output from the new technologies. A solution might be at hand, though, and would not involve radical changes to the existing infrastructure. Treating groups of dispersed power sources, such as solar and wind generators, as a single entity could solve the problem, creating the virtual equivalent of a single large power station.

European Union emissions of climate-changing greenhouse gases (GHG) declined for the third consecutive year in 2007, according to the EU's GHG inventory report compiled by the European Environment Agency. The EU-27's overall domestic emissions were 9.3 % below 1990 levels, which equalled a drop of 1.2 % or 59 million tonnes of CO2 equivalent compared to 2006. The EU-15 now stands 5 % below its Kyoto Protocol base year levels.

Selon le chef de la division commerciale, Andreas Dill, "l'astuce consistait à combiner notre grande expérience en matière d'équipement d'impression de disque optique (CD/DVD/Blu-ray) avec notre technologie de pointe de nano-enduction." Il en résulte, Solaris, la première machine nanotechnologique unique pour l'enduction, conçue pour la production de masse.

Mené conjointement par Elioth, filiale du groupe Iosis spécialisée dans la recherche et développement, et l'agence d'architecture "Encore heureux", le projet « Wind-it » envisage d'utiliser les structures du réseau de transport d'électricité comme des supports à éoliennes. Il vient de recevoir, Outre-Atlantique, le premier prix du concours "Metropolis Next generation Design Competition".

Le groupe, qui détient déjà 20% du marché mondial du verre photovoltaïque, a créé Saint-Gobain Solar, une entité dédiée à l'énergie solaire. Cette société lance une offre complète de solutions photovoltaïques intégrées à l'enveloppe du bâtiment, allant jusqu'à l'installation.

Le lien entre croissance économique et croissance de la demande électrique est à nouveau confirmé. Nobuo Tanaka, le directeur général de l'Agence Internationale de l'énergie, a présenté à l'occasion du G8, à Rome, un rapport faisant état d'une baisse de 3,5% de la demande d'électricité dans le monde en 2009.

Consumer Focus is today warning that the Government’s energy efficiency plans are too underfunded, untargeted and under-prepared to tackle the fuel poverty crisis affecting more than 5 million vulnerable pensioners, families and disabled people across the UK.

In this work, some fundamental aspects concerning the efficiency of induction machines are treated. The standards and the therein prescribed methods for the determination of the energy efficiency of induction machines are discussed. A detailed comparison of the four most relevant and recent methods identifies the differences. By means of measurement results of different machines, the differences between and the shortcomings of certain methods is confirmed. In that context, special attention is paid to the new, so-called ‘Eh-Y’ method. A concise overview of the most important points of attention for an increased efficiency of motor drives en the role of the induction motor (efficiency) in this context is completed with some examples. The difference between motor and generator mode is discussed and explained based on measurement results of machines of different size and efficiency class. Special attention is paid to the behaviour and performance of induction machines supplied by unbalanced voltages. More specifically it is investigated if and how the susceptibility to voltage asymmetry is influenced by material choice, in which the main focus lies on copper rotor technology. Therefore, the different standards for the description and quantification of voltage unbalance are studied first. The theoretical discussion is backed-up with experimental results of several machines.

One of the more aggressive developers is Ford, which has test vehicles on the road as part of its plan to bring electrified vehicles to market over the next four years. Although not alone in its drive to capture this potentially valuable market, Ford’s strategy and product range reflects the market sentiments; primarily that there is no silver bullet. To be successful requires a portfolio of technologies.

Technological advancements in wind energy efficiency have generally come incrementally and usually made via a process of increasingly large wind turbine blades. Put simply, the model has been: longer blades = more output per turbine.
