Comment: Recession? What recession?

Good news from renewables as Dieter Holm looks forward to the International Solar Energy Society (ISES) SWC2009 in South Africa later this year...

Snapshot: Spain in a nutshell

José Luis Briceño, director of Industry and Technology at the Trade Commission of Spain gives us some facts and figures from Spain’s renewables sector

Geothermal power generation in Germany – challenges for plant and materials engineering Geothermal power generation in Germany – challenges for plant and materials engineering

Corrosive fluids and the high pressures required for the extraction of geothermal water turn geothermal power generation into a technical challenge. To ensure that geothermal power stations are both safe and cost-effective, TÜV SÜD experts analyse the individual risks and opportunities present at geothermal locations and advise plant owners and operators at every stage from planning through construction to operation.

EfW: could biogas be used to power fuel cells? EfW: could biogas be used to power fuel cells?

One of the major problems for fuel cells is the fuelling infrastructure itself. Hydrogen – the fuel of choice from an environmental or energy efficiency perspective – is not yet widespread enough to drive fuel cells towards the mainstream, and other fuel choices such as natural gas are equally problematic. But one fuel cell company in the USA has found an answer by powering fuel cells with biogas derived from a number of different applications.

Options for micro-wind generation: part 2

Predicting real-time energy yields is critical to ensuring that urban wind turbines are designed, constructed and installed in the most viable manner. In the second of a series of three articles on urban wind energy, Bill Holdsworth looks at predicting the energy yield, and architectural solutions.

Comment: US deal offers glimmer of hope

So, it finally happened. By the slimmest of margins (219-212) the US House finally approved the Waxman-Markey American Clean Energy and Security Act (H.R. 2454) legislation, which some – most notably Al Gore - are hailing as the most important legislation Congress will ever pass...

"Yes to RES": US wind industry rallies in Chicago

Steve Sawyer reports back from some notable events, including the second (of 6) negotiating sessions leading up to the UNFCCC cop 15 in Copenhagen, where the world is supposed to agree a new comprehensive global agreement to combat climate change …

US sets the standard with Federal renewable electricity Bill

For the first time in history, a US Congressional committee has approved legislation that would establish a federal renewable electricity standard as well as a price for carbon emissions. Don C. Smith examines the Bill's most important provisions and assesses the reactions of the American renewables and energy efficiency communities towards the Bill.

US Senate committee finds it tough going US Senate committee finds it tough going

Like the house, the US senate is also pushing forward with a renewable electricity standard (RES) as part of its Energy Bill. Sen. Jeff Bingaman, chairman of the senate energy committee, had to reduce the res to 15% by 2021, to get enough votes to pass the provision and include it in the broader energy bill the committee passed. Steve Barlas reports.

Can landscape architects aid wind development?

How important is a landscape architect to wind energy development? Richard Foote accompanies RSK Environment on a confidential project in the UK to find out.

Solar mapping: demystifying solar potential

Talk to anyone and they'll tell you in principle they think solar energy is a good idea. But we haven't harnessed it for conversion to electricity utnil fairly recently and even today barriers still exist that -prevent solar energy entering the mainstream. But could solar mapping help bring the technology further into the public domain?

Intersolar 2009 report

Held in Munich from 27 May through 29 May, the Annual Intersolar tradeshow at 100,000 square metres and over 1400 exhibitors remains the standard for tradeshows in the global solar industry.

Rise of the superconductor

Could superconductors transform the economics of wind power?
