Highlights from the 2015 Geneva Motor Show

Wind Power

Last year we reported on the ongoing sustainable makeover of the Eiffel Tower's first-floor. Work continues on turning the tower green, and as part of this process, New York's Urban Green Energy (UGE) recently installed two wind turbines that should reduce the carbon footprint of the iconic landmark.  Read More

The Dutch Windwheel concept is a mixed-use development comprising two rings, one of which ...

The Dutch have long used windmills to harness wind energy. A new concept proposed for city of Rotterdam, however, is surely one of the most elaborate windmills ever conceived. The Dutch Windwheel is a huge circular wind energy converter that houses apartments, a hotel and a giant coaster ride.  Read More

The hull of the cargo ship Vindskip acts as a large wing sail (Image: Lade AS)

In 2013, Norway's Lade AS unveiled designs for Vindskip, a "hybrid" merchant ship which aims to harness the wind courtesy of a specially-shaped hull, in the process taking the burden off of its natural-gas powered engines and saving fuel. Researchers from the Fraunhofer Institute's Center for Maritime Logistics and Services (CML) have been working to help realize this goal by developing an algorithm that will allow the Vindskip's navigation system to use the combination of power and sail at its most economical.  Read More

Scotland's Whitelee wind farm (Photo:

Scotland is pushing ahead with green energy, with First Minister Alex Salmond claiming that renewables could provide 100 percent of Scotland's energy by 2025. And last month, Salmond's push for wind farms appears to have borne fruit – wind power alone generated some 126 percent of the energy needed to power every home in Scotland in what the World Wildlife Foundation (WWF) is calling a "bumper month." Even solar fared well despite the chilly conditions, with domestic solar PV panels chipping in around a third of the domestic energy bill.  Read More

This large buoy has an array of advanced scientific instruments to measure offshore wind e...

Offshore wind power in the United States is nowhere close to meeting the potential this renewable energy form has to offer. There are a myriad of reasons why, including lack of information on energy-harnessing possibilities at specific sites. The US Department of Energy’s Pacific Northwest National Laboratory (PNNL) is looking to change this, by dropping two very advanced data-collecting buoys into coastal waters.  Read More

WindStream Technologies says it has installed the world's largest wind-solar hybrid genera...

Generating renewable electricity at home or commercial buildings is becoming increasingly viable. WindStream Technologies has installed what it says is the world's largest wind-solar hybrid array on an office roof in Kingston, Jamaica. The array is expected to generate over 106,000 kWh annually.  Read More

Solar Wind Energy's Downdraft Tower generates its own wind that is directed down the hollo...

When we think of wind power, we generally think of huge wind turbines sitting high atop towers where they can take advantage of the higher wind speeds. But Maryland-based Solar Wind Energy, Inc. is looking to turn wind power on its head with the Solar Wind Downdraft Tower, which places turbines at the base of a tower and generates its own wind to turn them.  Read More

GE has found a way to extend wind turbine rotor blades without replacing them

Sometimes progress can be its own worst enemy, with early adopters being stuck with obsolete equipment that leaves them with the choice of living with out-dated technology or an expensive replacement. The green energy field isn’t immune to this, and as part of a US$2 million renewable energy project, GE has developed a way to make smaller, less efficient wind turbines into bigger more efficient ones with a bit of plastic (or carbon composite) surgery.  Read More

The Windpax wind turbine system can be set up in less than two minutes and mounted on a nu...

Keeping mobile electronic devices powered up can be difficult for the modern camper and hiker. Generating power from Mother Nature in the form of wind and sun is the preferred option for many, with a number of portable solar and wind generators emerging to fill this need. The latest is Windpax, a collapsible, portable wind turbine system designed to not take up too much space in a backpack.  Read More

A model of a high altitude aerial power plant that harvests both solar and wind energy and...

Harvesting power from the wind and the sun is nothing new. We've seen flying wind turbines and solar power plants that aim to provide clean renewable energy. UK-based New Wave Energy has a bolder idea in the works. The company plans to build the first high altitude aerial power plant, using networks of unmanned drones that can harvest energy from multiple sources and transmit it wirelessly to receiving stations on the ground.  Read More
