  • Energy management and conservation are the keys to using fuel and electrical energy in the most efficient way. Proper energy management can lead to big savings on the operating costs of a building. If fuel and electrical energy consumption are reduced, money will be saved as a result. Many residential, industrial, and commercial buildings have already undergone changes that have resulted in the savings of both energy and money. Any building can be made more energy efficient when proper energy management procedures are applied....

  • Renewable Energy is energy generated from natural resources - such as sunlight, wind, rain, tides and geothermal heat - which are naturally replenished. In 2008, about 18% of global final energy consumption came from renewables, with 13% coming from traditional biomass, such as wood burning. Hydroelectricity was the next largest renewable source, providing 3% (15% of global electricity generation), followed by solar hot water/heating, which contributed with 1.3%. Modern technologies, such as geothermal energy, wind power, solar power, and ocean energy together provided some 0.

  • Grid-connected photovoltaic power systems are power systems energised by photovoltaic panels which are connected to the utility grid. Grid-connected photovoltaic power systems comprise of Photovoltaic panels, MPPT, solar inverters, power conditioning units and grid connection equipments. Unlike Stand-alone photovoltaic power systems these systems do not have batteries. When conditions are right, the grid-connected PV system supplies the excess power, beyond consumption by the connected load, to the utility grid.[1]...

  • carbon dioxide recovery systems In the fermentation process, the yeast feeds on the wort to produce carbon dioxide and alcohol. This carbon dioxide can be recovered with closed fermentation tanks and used later in the carbonation process. The fermentation process generates about 8-10 lbs/barrel wort (3-4 kg CO2/hl) (Lom and Associates, 1998). Typical CO2 scrubber operations require 2 kg of water per kg of carbon dioxide (Dell, 2001). A large brewery can become self-sufficient for CO2 if a well-designed plant is installed to recover CO2 from fermentation. The U.S.

  • In many of our discussions with industry leaders, we have emphasised the need to install solar panels on the facades of new housing complexes and offices; we reiterated this more recently in last year’s Christmas letter to our members. We are now happy to announce that there has been a large step forward in this regard. The city of Zurich voted 167 to 0 in favour of renovating building envelopes in an energy-smart manner, rather than simply adhering to outdated building codes. And now an apartment building in Leimbach, on the outskirts of Zurich, is being renovated with a solar...

  • In recent years, the ICT market has quickly moved toward the integration of a large variety of functions into a single portable electronic equipment. The boundaries among different devices like music players, digital cameras or mobile phones are going to vanish. In this trend, one of the key factors is played by data storage, since all these devices require a large amount of memory to store either audio or visual data. Also, the energy consumption needs to be reduced to further extend battery duration and the functionality of the devices....
