Features

Offshore transmission – options for grid connection
Despite many similarities, offshore wind is a step ahead of marine renewable deployment, but how can the industries pull together to overcome shared challenges and accelerate their emergence as mainstream technologies?
By Steve McDonald

Best practice – solar obligations becoming mainstream
In many countries there is a trend towards solar obligations for new buildings or those undergoing major renovation. This mechanism, which obligates developers to install solar equipment, is considered as the single most powerful instrument to
promote solar thermal generation.
By Uwe Trenkner and Raffaele Piria

Innovation – the ingenious is always simple
As a company strategy Vensys Energy AG of Germany aims at entering new wind markets by issuing wind turbine production and geographical sales licence packages for local partners to manufacture its direct drive wind technology. Licence partner CKD NOVÉ Energo is one example.
By Eize de Vries

Spread it around – biogas in the grid
Tensions in the Middle East and the gas price conflict between the Ukraine and Russia have generated a great deal of unease in Europe over energy supply security. The answer to the problem is home grown: biomass energy that can be distributed utilizing the existing gas pipeline network.
By Simon Ford

Sourcing components – the challenge of sourcing quality wind turbine
components and reliability issues With demand for wind turbine components surging, developers piling on pressure to deliver ever-larger turbines, and insurance companies demanding tougher reliability clauses, manufacturers are facing an engineering minefield.
By Eize de Vries

Keeping it clean – reducing environmental impacts from solar PV
Measures to reduce environmental impacts could also lead to a cost reduction in the manufacture of crystalline silicon modules. But what are the most important options to reduce environmental impacts and what are the main barriers to their implementation?
By E. A. Alsema and M.J. de Wild-Scholten

Shrinking costs down to size – sunny outlook for small tech in solar
The market has taken a shine to an array of nano-based technologies that now challenge traditional photovoltaics on their home turf. Is the unseen world of nanotechnology about to become very big in the eyes of the world?
By Tom Cheyney

Husum 2007 – wind technology overview
Wind turbine buyers are faced with serious equipment delivery periods of two years and longer. As a consequence many suppliers seem so busy turning out their volume models in big numbers that the development of next generation wind turbines seems to have become second priority.
By Eize de Vries

Price parity for US solar: is the goal within sight?
Rising fossil fuel costs and a dramatic up tick in solar installations may at last help the US solar industry achieve its goal of price parity with grid power. State and federal efforts to achieve this landmark are yielding fruit at last.
By Elisa Wood

UK tidal – ebbing it on
Harnessing the energy of the UK’s River Severn, which has the world’s second largest tidal range, has long been a dream for ambitious engineers and governments alike. Now, a new impetus on low carbon generation has prompted another re-examination of the issues involved with a new report by the Sustainable Development Commission.

FROM THE EDITOR

During a busy season of renewables events over the past couple of months, and listening to a good number of industry leaders and CEOs discussing aspects of our industry, I was struck once more by something very special about the renewables business. For yes, while money does make the world go around (and some of the PV bosses said their firms are expecting growth of 70% or more this year) there is something else going on as well.

Driving many of these businesses – along with some good policies and consequent vibrant markets – is an underlying vision for a cleaner and more egalitarian way of delivering usable energy to all. Many of this industry’s leaders, and their teams, are passionate about what their technologies can contribute – whether in developing countries, by helping stimulate local economies and slowing migration to cities, or in developed urban centres where renewables can become part of a new architecture. They know their technologies can produce large amounts of power or heat without need for fuel and with zero or low carbon emissions.

Some visions are for what can be achieved today, and others look further ahead, beyond the confines of established ideas of how heat and power supplies ‘have’ to be. What they share is a commitment to using resources intelligently in a move towards a lower-carbon world.

An industry of tree-huggers? No, it’s an industry marked out by a high proportion of strongly motivated individuals and businesses putting their time and energy into good business, and with a sense of purpose that goes beyond simply dollars, euros or widgets.

The same sense of purpose shines through in the articles in our current issue. To mention just a few: Eize de Vries visits Vensys, a business whose innovative wind technology goes back a decade, and also presents innovations from this year’s Husum Wind. Uwe Trenkner and Raffaele Piria of ESTIF describe how a number of countries now have legislation requiring the installation of solar thermal in new buldings. Elisa Wood describes how US solar is achieving grid parity on cost, while Simon Ford explains how biogas can significantly supplement natural gas in meeting Europe’s energy needs.
