Two Steps Forward, One Back: Ontario Cancels Feed-in Tariffs for Large Projects

Two Steps Forward, One Back: Ontario Cancels Feed-in Tariffs for Large Projects

There’s no sugar-coating what happened last week. Ontario’s Minister of Energy, Bob Chiarelli, used the occasion of the annual conference of the Canadian Solar Energy Industry Association (CanSIA) to announce that he was canceling feed-in tariffs for large projects.
Solar Trackers: Facing the Sun

Solar Trackers: Facing the Sun

The use of tracking technology allowing solar modules to follow the course of the sun (and so optimize the incident angle of sunlight on their surface) can increase electricity production by around a third, and some claim by as much as 40% in some regions, compared with modules at a fixed angle.

Wind Technology Trends: Why Small Steps Matter

Wind Technology Trends: Why Small Steps Matter

More than 31,000 MW of new wind capacity was added worldwide in 2008, a record that can be described as an absolute milestone in the modern history of wind power development. Fortunately that build up -- and the dip in overall wind market demand that has followed the financial constraints -- did not take place at the expense of wind industry development nor technology innovation.
Flying green: The use of biofuels for aviation

Flying green: The use of biofuels for aviation

Commercial and private aviation is growing rapidly around the world, but the increasing cost of fuel, and pressure to reduce emissions is leading airlines to look at more environmentally friendly sources of energy. Jeffrey Decker looks into the use of biofuels for aviation.
A solid foundation: Technological developments from the DEWEK conference

A solid foundation: Technological developments from the DEWEK conference

In late November 2006, members of the wind industry gathered in Germany to discuss the latest technical developments in the field. Eize de Vries attended the meeting reports on some of the latest research and innovations that were unveiled at the DEWEK conference.
Small wind turbines: Driving performance

Small wind turbines: Driving performance

Small on-site turbines have a long history. Now the arrival of small, domestic-scale wind turbines on the shelves of hardware stores has been welcomed by many but criticized by others as 'vanity' development, rather than a serious commitment to low-carbon generation. Sander Mertens and Eize de Vries explore the issues and focus on urban wind turbines operating in the highly complex flow of the built environment.
Experiences with Establishing a Lubricant Maintenance Program

Experiences with Establishing a Lubricant Maintenance Program

To standardize lubrication practices for hundreds of pieces of equipment at its four hydroelectric projects, Grant County Public Utility District established a lubricant maintenance program.
North Sea construction: Installing monopiles for the Dutch Q7 offshore wind farm

North Sea construction: Installing monopiles for the Dutch Q7 offshore wind farm

In October 2006, and under considerable time pressure, Dutch contractor Mammoet Van Oord began the installation of 61 monopile foundations for the 120 MW Q7 offshore wind farm. In mid-March Eize de Vries spent a day at the North Sea site, onboard the self-elevating jack-up installation barge, Jumping Jack, to experience first-hand the construction work in progress.
