Many different power distribution configurations exist today that can be used to power a data centre. Each of these configurations has its own advantages and disadvantages, which can have a major impact on all aspects of the facility.
This paper discusses the qualitative differences between seven possible configurations that can either be found in the United States or Canada today, or could be used in the future.

This Application Note provides an overview of available measures for energy efficiency improvement in the food and beverage processing industry. It is based on examples from theory and practice.
This study is not intended to be an exhaustive description of every operation in the sector, but rather tries to describe the most significant process-specific energy efficiency measures and reinforce these with practical case-studies.

The IEP roadmap to 2050
In December 2009, the International Electricity Partnership (IEP) published its 'Roadmap for a Low-Carbon Power Sector by 2050'. The IEP was created in October 2008 at an international summit of electricity chief executives held in Atlanta, USA. Its roadmap focuses on Australia, Canada, the European Union, Japan, and the United States.
The IEP industry leaders see a crucial role for the electrical power sector. Historically, electrical power has been the largest source of CO2 emissions, the main contributor to climate change. But in the upcoming decades electricity can become a key lever in evolving towards a low carbon economy, states the IEP. The key technological evolutions necessary to make this happen are the electrification of heating and transport, and carbon-free power generation.
Aggressive application of technology
The report sets a target of 60% to 80% reduction in carbon emission by 2050. According to the Intergovernmental Panel on Climate Change (IPCC) this is the level of reductions required to stabilise greenhouse gas emissions in the atmosphere at 450 to 550 ppm CO2eq. This is estimated to correspond with an average global temperature rise of 2-3 °C. The IEP argues that reaching this target is only possible through an aggressive application of technology. It advocates policies that provide incentives for high investments in renewable energy, Carbon Capture and Storage (CCS), nuclear power, smart grids, electric vehicles, heat pumps, and energy efficiency.

Binu ParthanBinu Parthan, Deputy Director General of our partner The Renewable Energy & Energy Efficiency Partnership (REEEP) declared that “REEEP believes that the project-by-project determination of additionality in the current CDM procedures for clean energy technologies does not have the intended effect. REEEP calls on those responsible to categorise all renewable energy and energy efficiency technologies as additional, i.e. to pre-determine additionality at the technology level.

In order to combat global warming, a detailed knowledge of the greenhouse gas (GHG) emissions associated with different energy conversion technologies is important. For nuclear energy, GHG emissions result from different process stages of the whole fuel cycle. A life-cycle assessment offers the opportunity to properly calculate these emissions. In the past, both indirect energy use and GHG emissions were studied by many researchers. Most of the studies result in low indirect emissions comparable to windturbines.

At a distance of about 30 cm from a fluorescent lighting tube with magnetic ballast and electronic starter, which is normally regarded as fairly electromagnetically compatible, this mains independent, battery powered thermometer was operated. It displayed the temperature flawlessly until – oops – somebody switched off the light at the wrong moment. It’s all no use – the battery has to be taken out and put back in: the only way to get the thermometer functioning again.
