A philosophical diatribe to start your week.

The EU yesterday denounced a House of Commons report calling for a moratorium on the increased use of biofuels and made plain it would stick to mandatory targets for the use of biofuels in transport when it unveils a climate change package today. Yesterday's report from the Commons environmental audit committee warned that biofuels were too expensive, environmentally damaging and making a negative contribution to cutting greenhouse gases, and said British government and EU plans to force greater use of biofuels should be rethought. In an unusually strong criticism of the Commons committee, Andris Piebalgs, the EU commissioner for energy, insisted that biofuels had to be supported as the "most immediately feasible way" of reversing greenhouse gas discharges from cars. "The [European] Commission strongly disagrees with the conclusion of the British House of Commons report," said Piebalgs.

...one step closer to building a magnetic-cooling system that promises energy-efficient, environmentally friendly, and completely silent fridges

The paper itself is flawed suggesting that virtualisation can reeduce the number of servers required to 7% - enough to handle the average processing load. Webusers want instant reaction during the peak - for that you need spare capacity. Is this a surprise?

The Internet doesn't produce belching smokestacks or toxin-spewing drainpipes. Instead, the environmental impact of the data centers that power the Web and private networks is about as visible as the electrons moving around a company's servers. But visible or not, the ecological and economic costs of those servers are massive. A report released last week by the Environmental Protection Agency estimated that U.S. data centers (collections of computers used to power businesses' and government agencies' IT infrastructures and Web sites) consumed around 61 billion kilowatt-hours in 2006 at a cost of about $4.5 billion. That's about 1.5% of total U.S. electricity consumption, more than the electricity used by American televisions, or equivalent to the output of about 15 typical power plants

The Environmental Protection Agency (EPA) and the Departments of Agriculture and Energy held a press conference yesterday about the Obama administration's proposal to increase research on biofuels and stimulate their commercialization. The Energy and Independence and Security Act (EISA) of 2007 mandates that 36 billion gallons of renewable fuels be produced by 2022.

"Every continent on the planet is surrounded by a cleaner, safer, more efficient answer to our energy needs. The power in ocean waves. Ocean Power Technologies (OPT) is a leading renewable energy company specializing in cost-effective, advanced, and environmentally sound offshore wave power technology. The electrical power generated by OPT's technology is key to meeting the energy needs of utilities, independent power producers and the public sector. OPT's PowerBuoy® system extracts the natural energy in ocean waves, and is based on the integration of patented technologies in hydrodynamics, electronics, energy conversion and computer control systems. The PowerBuoy is a "smart" system capable of responding to differing wave conditions. The result is a leading edge, ocean-tested, proprietary system which generates reliable, clean, and environmentally-beneficial electricity."

"The International Code Council (ICC) earlier this week launched the first public version of the International Green Construction Code (IGCC), which aims to bring together standards for the environmental performance of commercial buildings."

"Facility Could Meet up to 75 Percent of Cape Cod and Islands' Electricity Demand CAMBRIDGE (April 28, 2010) - Leading environmental organizations hailed today's historic decision by Interior Department Secretary Ken Salazar to provide federal approval for Cape Wind, allowing the country's first utility-scale offshore wind farm to move forward. The announcement signaled the Administration's intentions to support renewable energy development off U.S. shores, a major component of a clean energy economy and reduced dependence on fossil fuels, the organizations said. Today's announcement ends a nearly nine-year environmental review process, much longer than is typical for a traditional coal power plant. The decision clears the way for Cape Wind to begin the permitting process and develop a 130 turbine wind farm in Nantucket Sound, which could meet as much as 75 percent of the electricity demand for Cape Cod and the Islands."

Top-level executives disagree with other senior executives on how much their companies are doing to address energy efficiency, according to a study by the Economist Intelligence Unit (EIU). In the survey by EIU and Ingersoll-Rand, 49 percent of C-suite executives said their organizations do not do enough to integrate energy efficiency into business strategy, compared to 61 percent of executives below that level.

By Jorge Moreno, Environmental and Building Technologies, Frost & Sullivan With more end users focusing on reducing energy costs, energy-saving water-to-water heat pump (WTWHP) chillers are being deployed to reduce a facility's utility bills. A WTWHP chiller is a water-cooled chiller that is designed to produce hot water at a specified temperature. The use of a WTWHP chiller is very similar to a conventional centrifugal chiller except for the fact that it uses two compressors, slightly different piping configurations, and more advanced controls in order to balance cooling and heating loads. In a conventional chiller, cold water is produced for comfort cooling, and the hot water that is extracted from the refrigeration process goes into a cooling tower and is released into the atmosphere. In a WTWHP chiller, this hot water is captured and relocated to a second heating stage, where the temperature is raised and the water is used as a heating source for a building's heating requirements. The key strength of WTWHP chillers is the high coefficient of performance (COP) that translates into significant energy savings and a shorter payback period. On the other hand, the key weakness is that it can only provide such benefits in a narrow range of applications primarily due to its coincident need for cooling and heating requirements throughout the year to ensure efficiency. A coincident need means that the application demands sizable water heating load along with the typical high cooling requirements in summer, and a sizable chilled water load along with the typical heating requirements during winter. Cooling output is directly dependent on the demand for heating, and vice versa. Consequently, in the absence of sufficient heating requirements, there is only a limited amount of cooling that can be produced. Any excess heating or cooling cannot be stored and hence, it is critical to align the cooling with the expected heating requirements. Coincidentally, in the absence of suf

A few good points. And whether we agree on climate science or not, the scientific debate should remain open and serene. In the end, there will always remain a degree of uncertainty, and the decision to act, and to what extent, becomes then a political choice.
