Safety In Numbers: Distributed Generation's

Distributed generation gives building owners the option to generate their own energy in one form or another. Utilities can maintain the system when the building owners do not want to manage it.

Small Hybrid Solar And Wind Energy Systems

The small hybrid solar and wind energy system at NREL's Outdoor Test Facility produces 1,400 watts of power from solar and 900 watts from the wind turbine, enough to power a refrigerator, lights, heaters, air coolers, computers and a radio.

The Hydrogen Economy And Fuel Cells

Fuel cells will be one of the key components in the hydrogen economy. They will replace the internal combustion engine and will convert the future main store of energy (hydrogen) to power when it is needed.

ULTRACAPACITORS AND THE HYBRID ELECTRIC VEHICLE

Compact in size, ultracapacitors can store an incomparably higher amount of energy than conventional capacitors. Indeed, ultracapacitors are currently available on the market with capacitance ranges up to 2700 Farads, and they can release that energy at both a high or low rate.

What Is A Green Tag?

Utilities by law, in all 50 States, have to purchase clean energy for every green tag sold. This means that when you buy a Green Tag, you can be assured that somewhere in the grid those electrons were produced using clean power.

A Router for Electrical Energy

Overall, the 'router' for power is a first step towards an energy model that is more efficient because it uses locally generated power at the highest possible efficiency. As more and more manufacturers design their electronic appliances to be DC compatible, the concept will proliferate.

Beyond Solar's Growing Pains The Future Is Bright

Even though they admit that the road ahead is fraught with danger and difficulty, industry experts are still confident that the price of solar will be competitive within the next 10 years. When this long-awaited day finally comes, I wonder if the industry will be adequately prepared?

Energy Capital VS Energy Income

The major difference between the financial and the energy world is that our current energy capital IS NOT replaceable; it is by it's very nature "non-renewable". As a result, our job as managers of our planet's energy portfolio is to create an "energy balance sheet" that has the proper mix of fossil fuels and renewable energy sources.

So You Want Electric Cars??

The Universal Automobile (UA) is a "public domain" vehicle used by subscribers; it is powered by batteries which can be automatically trickle-charged using "charging mats" deployed across preferred downtown locations designated as "UA Parking Areas" , or alternatively, their batteries can be quickly exchanged at traditional gasoline stations converted to accommodate automatic "swapping"..

There Is No Global Fresh Water Issue

Zonnewater developed a desalination unit based on solar energy (95% thermal and 5% photovoltaic or wind energy), suited for coastal areas with an average temperature of 30 degrees Celsius. The prototype is a small one cubic meter greenhouse-type construction that produces 40 litres of water per day.

VEGGIEBENZ

The engine is running smoother, quieter, and although veggie is supposed to have 6% less BTU, performance and mileage do not seem to be affected. Emissions definately have been affected positively. No black smoke and the exhaust smells better.

Water Wisdom

Grey water reuse offers a wonderful opportunity for us to maintain the sort of gardens we want, without wasting a single drop of precious drinking water.

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.
