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.
WHAT AMERICA NEEDS NOW
"We are like tenant farmers chopping down the fence around our house for fuel when we should be using Nature's inexhaustible sources of energy - sun, wind and tide. I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that." - Thomas Alva Edison (1847 - 1931)
Coming In Out Of the Cold: Hybrids Put To The Test
Some of the questions we have for hybrid technology are now dependability in cold weather starting, reliability in highway driving standards, added to these ever so alluring fuel cost savings.
Fresh Outlook On Fresh Air
Solarwall is a solar, fresh air, heating and ventilation system
Learn To Conserve
If you want to have a renewable energy system you need to learn to conserve well in advance of buying the system.
No More Coals To Newcastle!
The concept of using biodiesel may seem a new one, but it is not. Rudolph Diesel's first engine ran on peanut oil and now, a century later, it seems we are finally learning that natural oils are better for our health , our environment and ultimately our economy than fossil alternatives.
Parishioner Donation Sparks Solar Electric System Installation At St. Frances Cabrini Catholic Churc
Starting with an anonymous donation and some bright ideas from a design consultant, combined with the ambition and organization of parish staff, and the helping hands of 17 women and an environmental business; this system is truly a symbol of what collaborative team effort can do for sustainable development.
