Discredited strategy Increasing allegations of corruption and profiteering are raising serious questions about the UN-run carbon trading mechanism aimed at cutting pollution and rewarding clean technologies, writes Patrick McCully, executive director of US thinktank International Rivers

In October, Sawyer paid US $25 000 for a brand-new black 2008 Toyota Prius. But compared with his RAV4 EV, it was a gas guzzler, going only 1 or 2 km electrically before switching on its internal combustion engine. So Sawyer wrote a check for the car, then drove it directly to Hybrids Plus [see our sidebar,"Getting on the Grid"], also in Boulder, where he wrote another check, for $32 000—to have his shiny new Prius converted into a PHEV. (The radio-telemetry business has been very good to Sawyer.)

The world needs to build 30 nuclear power stations and the equivalent of two Three Gorges dams every year to prevent dangerous climate change, the International Energy Agency has said. It also needs to build 13,000 wind turbines and 40 coal and gas power stations fitted with carbon capture and storage technology each year between 2013 and 2030, the head of the Agency told the climate change conference in Bali.

he scheme would literally part the Red Sea with a massive wall more than 150 metres high, one kilometre thick and 100 km long, stretching between Yemen in the north and either Eritrea or Djibouti in the south. Details of the proposed dam are published in the current issue of International Journal of Global Environmental Issues (DOI: 10.1504/IJGENVI.2007.016114).

As you would expect from a Foster + Partners project, the self-contained city within a city has green energy management at the very heart of the design. Crystal Island will generate low carbon energy from solar arrays and wind turbines located on the building with vast atriums to regulate the internal air temperature during the extremes of the Russian summer and winter.

IF IT happens, it will be the space engineering feat that tops them all. Spanning several square kilometres, a space power station would be by far the largest orbiting structure ever built, dwarfing the International Space Station like a skyscraper towering over a tin shack. More importantly, it could be the answer to our energy woes.

Thanks to the efforts of more than 35 manufacturers, a wide range of computer products now include internal power supplies that are at least 80% efficient, that is, less than 20% of the power fed into them is lost as heat

After ten years of research and development, Statkraft believes the time is now right to build the first osmotic power plant prototype and is therefore stepping up its initiatives and investments to develop the technology. With this decision Statkraft will have invested more than NOK 100 million to develop a new, renewable energy technology. The research work is supported by The Research Council of Norway.  The global technical potential for osmotic power production is estimated at around 1600 TWh, including around 200 TWh in Europe and 12 TWh in Norway, or 10 percent of Norway’s current power production. The innovation has already attracted attention in the international energy community.

A Williams International 40 kW turbine drove an alternator which powered the battery-electric powertrain. The turbine design included a recuperator.

The European Union's (EU) energy objectives, legislation and programmes are determinant for the current strategy for the promotion of renewable energy sources (RES) and energy efficiency (EE) in Spain, which is becoming a key element for its international competitiveness.Firstly, this article explores the evolution of the EU's energy strategy, focusing on the adopted legislations and programmes to promote RES and EE. It concludes with an analysis of the impact of those measures in Spain.

wattwatt (a play on the words 'what' and 'Watt') is an independent community website set up by the International Electrotechnical Commission (IEC), a Geneva-based, non-governmental and not-for-profit organization, leader in electrotechnical standardization. IEC believes that the question of electrical energy efficiency is one that needs to be addressed and that everyone of us, as individuals, has a part to play.

This report presents the results of the eleventh international survey. It provides an overview of PV power systems applications and markets in the reporting countries at the end of 2006 and analyzes trends in the implementation of PV power systems between 1992 and 2006.

China is proposing an international multilateral science and technology cooperation scheme to hasten development of clean renewable energies.

A new battle has begun over the next round of energy liberalisation. Commission proposals to complete the EU's internal market for gas and electricity are leaving France and Germany in a quandary, with EDF and E.ON facing either the dismantling of their transmission assets or tight regulatory restrictions.

The Building Owners and Managers Association (BOMA) International is asking its members to accept this 7-point voluntary challenge to reduce environmental impact:
