Thin-film solar cells are cheaper than traditional solar panels, such as those made of polycrystalline silicon, but the yield is lower. However, the combination of these properties is promising according to the Thin-Film Future conference organized recently by SolarPlaza in Munich. An impression of the heavily attended gathering.
In today's marketplace, energy has become a strategic issue. Organizations of all types, including corporations, government agencies and non-profits, are evaluating where they get their power, how much they use and what they're spending for it.
Generally, the greater the economic prosperity and the higher percentage of urban population, the greater the amount of solid waste produced. Reduction in the volume and mass of solid waste is a crucial issue especially in the light of limited availability of final disposal sites in many parts of the world.
This article is intended as a suggestion for manufactures of, and users of large wind turbines. Users have noted reliability problems mostly due to the use of a mechanical gear transmission required to transform the relatively slow rotational speed of the large turbine hub to the required shaft speed of the synchronous alternator.
A new eco-friendly £5 million private care home in Sussex has elected to use solar energy as the primary source for both its heating and lighting. Eric Hawkins, MD and founder of Powertech Solar, describes how the project has provided an ideal opportunity to demonstrate the energy saving potential of the company's Suntech Solar Commercial range.
I think it's feasible to be off the grid anywhere you have access to sun, wind, or water for power. However, the city planning department may have other ideas. I know a couple in southwest Oregon whose urban homestead was off-grid on a city lot for many years, but they had a community that was supportive of renewables.
Homeowners get a solar system that looks great and performs well—and one that installs quicker and easier than anything else on the market. Since the installation crew spends less time up on the roof and makes about 25 percent less rooftop penetrations, there is less wear and tear on a roof.
How far the current PV cost is still separated from grid parity depends largely on the geographical situation, on the price of grid electricity, and on whether it concerns a cheaper or a more expensive PV system.
There are fuel cells installed in stationary applications all over the world, in a wide variety of locations, including hotels, hospitals, schools, telecommunications towers, breweries and in some parts of the world, notably Japan, in houses and apartment complexes.
From start to finish, every single point of contact within the organization must deliver on its brand promise. Internal communications make up every communication touchpoint or contact with a company's people. This includes messages from leadership (or lack of) - whether delivered in person or in writing.
"FloDesign Wind Turbine Corporation is going to revolutionize the way we capture energy from the wind," says CEO, Stanley Kowalski III. "Our wind turbine will produce more wind energy with less impact on the environment. Our turbines are smaller, can function in a variety of climates, and can work closer to the ground."
Peak Oil is the maximum rate at which we can pump oil out of rocks. World Peak Discovery was 1964. Peak in US production was 1970, North Sea 1999, Mexico 2004, Saudi Arabia 2005.
The main challenge for manufacturers of diesel engines and generator sets is thus to reduce the level of harmful substances, while maintaining similar or better performance levels.
Reducing the carbon footprint of an office building can take many forms, from simple awareness initiatives urging employees to turn off lights to more comprehensive plans that rely on technology for systematic control over energy consumption.
Another aspect of this unique documentary which set it apart from the plethora of recent films covering the subject of global warming is that it did not just deal with global warming alone, but other abuses of the environment as well.

The Darfon G320 is the microinverter solution for today's high-power solar modules. The G320 handles 60- and 72-cell modules up to 350W DC and outputs up to 300W AC. The G320's 3-phase configuration accommodates the electrical distribution systems of most commercial buildings and to reduce, if not eliminate, the need for expensive transformers. The G320 comes in four voltage/phase configurations, so it can be installed in residential, commercial or utility applications.
