The U.S. uses more energy for air conditioning (AC) than all other countries combined; but its status as the world's largest AC energy hog may soon be in jeopardy, said a Univ. of Michigan researcher. A study shows that if the rest of the world adopts the same AC usage patterns found in the U.S., and more and more countries certainly are, eight nations have the potential to surpass the American yardstick of high air-conditioning use.
Sun-drenched rooms make for happy residents, but large glass windows also bring higher air-conditioning bills. Now a bioinspired microfluidic circulatory system for windows developed by researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University could save energy and cut cooling costs dramatically—while letting in just as much sunlight.
Each year, the Lawrence Livermore National Laboratory releases energy flow charts that track the nation's consumption of energy resources. According to the most recent charts, Americans used more natural gas, solar panels and wind turbines and less coal to generate electricity in 2012.
A new energy-efficient approach to building occupancy detection, a better way to detect heat loss in electric-vehicle batteries and a high-efficiency silicon solar cell—all developed or advanced at the U.S. Dept. of Energy (DOE)’s National Renewable Energy Laboratory (NREL)—have been named among this year’s most significant innovations by R&D Magazine.
Theoretically, hydropower can step in when wind turbines go still, but barriers to this non-polluting resource serving as a backup are largely policy- and regulation-based, according to recent research. Hydroelectric dams are controlled by guide curves that account for drinking water and droughts. They cannot simply release water to meet some electricity demand or hold back water when electricity is in low demand.
A group of Rice University mechanical engineering students are getting a charge out of having the coolest new shoes on campus. As their capstone project that is required for graduation, four seniors created a way to extract and store energy with every step. Their PediPower shoes turn motion into juice for portable electronics and, perhaps someday, for life-preserving medical devices.
New research reports that universal access to modern energy could be achieved with an investment of between $65 and 86 billion a year up until 2030. The proposed investments are higher than previous estimates but equate to just 3 to 4% of current investments in the global energy system.
A new report finds that the global manufacturing sector has made great strides in energy efficiency: The manufacturing of materials such as steel, cement, paper, and aluminum has become increasingly streamlined, requiring far less energy than when these processes were first invented. However, despite more energy-efficient manufacturing, the researchers found that such processes may be approaching their thermodynamic limits: There are increasingly limited options available to make them significantly more efficient.
New recommendations by a National Research Council (NRC) expert panel on green and sustainable building performance could lead to a revolution in building science by creating the first large building performance database, says panel member Paul Fisette, a nationally recognized sustainable building expert at the University of Massachusetts Amherst.
In some of the first results from a federally funded initiative to find new ways of capturing carbon dioxide (CO2) from coal-fired power plants, Rice University scientists have found that CO2 can be removed more economically using “waste” heat—low-grade steam that cannot be used to produce electricity. The find is significant because capturing CO2 with conventional technology is an energy-intensive process that can consume as much as one-quarter of the high-pressure steam that plants use to produce electricity.
The U.S. Department of Energy's National Renewable Energy Laboratory and Argonne National Laboratory this week announced the release of the Transportation Energy Futures study, an assessment of avenues to reach deep cuts in petroleum use and greenhouse gas emissions in the transportation sector. The project suggests opportunities for 80% reductions by 2050
As the laboratory construction industry struggles to recover, fume hood manufacturers jockey for better positions and products.
Recent research at Lawrence Berkeley National Laboratory finds utility customer-funded energy efficiency programs expanding across the United States. Spending on these programs, which are funded by mandatory charges on utility bills, will double to nearly $10 billion per year by 2025. Drivers for this growth include energy efficiency resource standards required of utilities.
The Federal Laboratory Consortium announced this week that the Department of Energy national laboratory in Richland is receiving three 2013 Excellence in Technology Transfer awards in recognition for creating technologies or processes that can store large amounts of renewable energy until it's needed, fight cancer and detect explosives, and then moving the innovations to the marketplace.
As data centers continue to come under scrutiny for the amount of energy they use, researchers at University of Toronto Scarborough have a suggestion: turn the air conditioning down. Their latest research suggests that turning up the temperature could save energy with little or no increased risk of equipment failure.
Rendering, or cladding, is the most common way of maintaining the look of an old house while adding insulation. But cutting panels to size and shape is a cumbersome process. Researchers in Switzerland, which has many old houses that need fresh insulation, have developed an aerogel-based plaster that is both easier to apply and provides better insulation.
Sewage sludge, wastewater and liquid manure are valuable sources of fertilizer for food production. Researchers in Germany have now developed a chemical-free, eco-friendly process that enables the recovered salts to be converted directly into organic food for crop plants.
Scientists in Singapore have invented a new toilet system that will turn human waste into electricity and fertilizers and also reduce the amount of water needed for flushing by up to 90%. Dubbed the No-Mix Vacuum Toilet, it separates liquid and solid wastes, using vacuum suction technology minimizes flushing liquid. The waste is then sent to bioreactors or used in fertilizers.
According to a recent report from Pacific Northwest National Laboratory, U.S. commercial building owners could save an average of 38% on their heating and cooling bills if they installed a handful of energy efficiency controls that make their heating, ventilation and air conditioning (HVAC) systems more energy efficient.
In the final part of the continuing Massachusetts Institute of Technology (MIT) study on scalable energy candidates, researchers from the MIT Energy Initiative discuss how a megawatt saved is better than a megawatt made, showing there are many ways to save energy without sacrifice.
With the introduction of a new chlorine manufacturing process achieved by combining oxygen depolarized cathode technology and new electrolysis technology, Bayer MaterialScience is poised to save enough electricity to power a small city.
The R&D Daily recently featured the new cool roof being installed at the historic Stanford Linear Accelerator Center dome at Lawrence Berkeley National Laboratory. But not all cool roofs yield the same results in cooling, and Berkeley Lab has now conducted a nationwide study to map the variations.
It stands to reason that the photovoltaic panels on a rooftop are not only converting sunlight to electricity, they are keeping the building cooler by intercepting the solar rays. Until recent research, however, just how much of a cooling benefit they can provide was not known.
While Berkeley Lab's third-generation synchrotron is better known as one of the world's brightest sources of ultraviolet and X-ray light, it's roof has been, until now, a prime attractor for the sun’s energy. The 70-year-old dome is being clad in a new cool roof, which will reflect sunlight back into the atmosphere. The project is part of a mandate by Stephen Chu for all Dept. of Energy facilities.
Power usage effectiveness (PUE) is a key metric for determining how green a data center is and it shows how effectively a data center uses power. Measured as a ratio of the total amount of power used in the data center divided by the amount of power to the computer equipment, the best score a data center can get 1.0. The National Renewable Energy Lab recently dropped its PUE from 3.3 to 1.15 in an effort to be a leader in this area, and to save hundreds of thousands of dollars.
