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.
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!
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.
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.
"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)
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.
Solarwall is a solar, fresh air, heating and ventilation system
If you want to have a renewable energy system you need to learn to conserve well in advance of buying the system.
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.
A Seattle Exhibitor's Web-based Renewable Energy Monitoring App For Residential Homes at the Midwest Renewable Energy Association's Energy Fair
As a professional, technical, and scientific service provider, ESA connects the best products, services and knowledge from the environmental industry to businesses and communities nationwide.
Simply put, HALT is superior to conventional testing because it is cost effective, faster, more accurate, compresses our product time to market, and maximizes customer satisfaction.
Apart from the small electronic component the whole installation can be made locally with materials available in nearly every part of the world, being glass and PVC piping and appendages.
Inverters convert the "DC" electrical power output of renewable energy technologies - such as solar, wind and fuel cells - to the high quality "AC" that our conventional power system require.
