Aprovecho Research Center's Sustainability Internship Program

During these internships students have hands-on opportunities to learn about organic gardening, sustainable forestry, appropriate technology, and ecological living skills.

Ballard Powers First Ford Production Fuel Cell-Powered Focus

Ballard® Fuel Cells to Power More Than 50 percent of Announced Demonstration Fleets Under U.S. Hydrogen Economy Initiative Ballard Powering the Largest Number of Fuel Cell Cars and Buses in the World

California Fuel Cell Partnership's Road Rally Places Record Number of People on the Road in Zero Emission Hydrogen Cars

Caravan of Fuel Cell Vehicles from Eight Auto Companies Cruises through Southern California

Florida's Use of Electric Drive Vehicles Garners "E-Visionary" Award from EDTA

Under Governor Jeb Bush, the state employs a variety of electric vehicles in parks, fleets, and communities.

President Signs Tax Bill That Includes Hybrid Vehicle Deduction

EDTA President Brian Wynne says, "Such incentives have spurred market demand for hybrids in the mainstream automotive market. Electric drive reduces our need for foreign oil and improves air quality, and this important bill rewards both consumers and businesses that use electric drive technology every day."

Carmanah Technologies Earns Prestigious World Technology Award Nomination

Nomination recognizes the work of greatest innovation and long-term significance within a particular field and is the first step toward WTN membership alongside such industry leaders as Apple, Sony, IBM, Royal Dutch/Shell, NASA, and Canada's Research in Motion.


Ultracapacitors Provide High-Reliability, Low-Maintenance Energy Storage Alternative to Batteries

RenewableEnergyStocks.com Reports as Oil Prices Rise, So Does Investor Interest in Sector

www.RenewableEnergyStocks.com, features the exclusive article "High Oil Driving Automotive Changes''.

Combining The Sun's Heat And Light Could Boost Water-Splitting Efficiency

Using the sun's heat and light together could be an efficient way to produce hydrogen, which in turn could be used to power cars, homes and businesses.

Education In Construction: Cat Announces The Wise Project

The project aims to minimise environmental impacts both during construction and during occupancy. Current best environmental practice in building is the BREEAM criteria - The Building Research Establishment Environmental Assessment Method.

IS 'CLEANER AND GREENER' TECHNOLOGY A Sufficient Solution To Our Sustainability Problem?

A Company that adopts a strategy of technological reform does not necessarily have to confront its unsustainable principles and priorities. It is not hard to imagine, for example, a company that replaces its gas-powered buses with electric ones, while continuing to use them to transport exploited workers to sweatshop factories.

Living Off The Grid

The charge for connecting to the grid would have amounted to $125,000., whereas the total cost for the Renewable Energy system was $25,000., - a savings of $100,000!

NEW ENERGY BILL: Reducing Our Dependence On Foreign Oil

The lion's share of oil consumption stems from transportation needs. In 2002, the transportation sector accounted for about 68% of total petroleum use with gasoline accounting for two-thirds of the petroleum consumed in the transportation sector.

One Year After The Big Blackout Alternative Energy Makes Gains

As last year's blackout showed, whenever what we know and trust fails us, we immediately seek out the alternatives. Which meant that stocks in alternative energy companies spiked significantly in the days following the blackout.

Reliable Pitching: Ultracapacitors And Wind Turbine Pitch Systems

Ultracapacitors prove to be a high-reliability solution for the severe power pulses needed for wind turbine pitch control.

Parker KleenVent provides closed-loop solution for wind turbine cooling systems

Parker KleenVent provides closed-loop solution for wind turbine cooling systems

Many 1.5 MW wind turbines use traditional open-loop water/glycol cooling systems. Regular water evaporation in the reservoir elevates the mixture's viscosity, prohibiting cooling of the IGBT and associated critical controls, causing the wind turbine to overheat unless serviced, which in turn means turbine downtime and high maintenance costs. Parker's KleenVent Coolant Evaporation Inhibitor (KV-CEI) is a simple add-on to the legacy cooling system, that eliminates water evaporation in the coolant solution and stops the ingress of airborne contaminants, by enclosing the cooling loop. The KVCEI also removes the need for continuous coolant monitoring during the warm season. Traditional maintenance calls to replenish or rebalance the fluids, take the wind turbine and transformer offline, resulting in significant downtime and revenue loss. Parker's cooling system solution optimizes wind turbine uptime and revenue, reduces maintenance costs and increases overall efficiencies.
