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