For example, there are industry standards for measuring energy usage in TVs and cable set-top boxes.
The Trust decided to branch out from its usual territory of measuring energy use and carbon footprints because there was not a global standard on water reduction, he added.
Since October, a team of Federal Agencies and Departments, led by DOE, has been working hard to refine methods for measuring energy performance and ways to communicate this information effectively to consumers.
The island nation uses 4, 500 BTUs per U.S. dollar of gross domestic product, a measure known as "energy intensity, " the world standard for measuring how efficient an economy is at using energy.
Measuring any change in dark energy requires creative thinking, which is where the clusters come in.
That means measuring and reducing the embodied energy of a product throughout the supply chain, from materials extraction to processing to transportation to product use and disposal.
It is based on indirect calorimetry, which determines energy expenditure of a person by measuring both consumed oxygen and produced carbon dioxide rates.
FORBES: Calories�Cthe ubiquitous term in health and fitness.
Secretary Chu announced earlier today that the Department of Energy has offered and Japan has accepted an aerial measuring system capability, including detectors and analytical equipment used to provide assessments of contamination on the ground.
Since Hurricane Katrina, the global accumulated cyclone energy index has declined to almost the lowest level since we started measuring such phenomena in the early 1970s.
If natural gas is to be a near-term solution for a clean energy future, the industry also must be much more rigorous in measuring, publicly reporting and fixing leaks in the production and distribution process.
When it's bolted onto the Blanco Telescope at the Cerro Tolodo Observatory in Chile next month the 570-megapixel Dark Energy Camera will survey some 300 million galaxies in the southern sky, measuring the speed at which they are moving apart with phenomenal accuracy, and giving the best description yet of the accelerating expansion of the Universe.
And it is by measuring the ratio of the latter to the former, and the behaviour of any excess across the energy spectrum, which may provide a way into the dark matter problem.
