California to Require Net-Zero-Energy Buildings
February 5, 2008 10:11 AM - , BuildingGreen
Every two years, the California Energy Commission (CEC) releases an Integrated Energy Policy Report in which it makes recommendations for energy policy in the state, including changes to Title 24, the energy efficiency portion of the building codes. In its 2007 report, CEC recommends adjusting Title 24 to require net-zero-energy performance in residential buildings by 2020 and in commercial buildings by 2030. According to Panama Bartholomy of CEC, the commission does not need new legislation to incorporate these goals and is already moving to put them in place. “The 2008 standards will get us closer to these recommendations,”Ł he said, referring to the Title 24 update currently moving through the state’s rulemaking process.
Chinese Factory Turns Environmental Bane into Boon
February 1, 2008 08:27 AM - , Worldwatch Institute
China is beginning to take advantage of an unusual energy source: cow gas. Cows emit a significant amount of methane, a powerful greenhouse gas, when they belch and flatulate. According to People’s Daily, the world’s largest cow-dung methane power plant started operation on January 21 in China’s Inner Mongolia region. With an investment of 45 million RMB (roughly $US5.7 million) from the country’s largest milk producer, Mengniu Dairy, the plant is able to supply 10 million kilowatt-hours of electricity to the national power grid.
New Solar Panel Technology Stylish and Sustainable
January 31, 2008 09:23 AM - ENN
The key component of the new modules is an organic dye which in combination with nanoparticles converts sunlight into electricity. Due to the small size of the nanoparticles, the modules are semi-transparent. This aspect makes them well suited for facade integration. The new solar cells are being developed by members of the Fraunhofer Institute for Solar Energy Systems ISE, who will be presenting their new technology in Tokyo at Nanotech 2008, the world’s largest trade fair for nanotechnology.
Scientists Call For Urgent Research Into 'Real' Impacts Of Invasive Species
January 30, 2008 09:17 AM - CABI
As well as drawing attention to the rising cost of invasive species on a global scale —estimated at US$1.4 trillion in damage — GISP stresses that too much emphasis has been placed on the problems faced by the agricultural sector in developed countries rather than in developing countries and on the “full range of environmental, social and economic costs.”Ł The report also emphasises that due to the lack of knowledge and research available on the severity of individual pests and the options for best controlling them, policy makers are being left in the dark.

Unofficially the United States is now in an economic recession. Investment bankers Merrill Lynch say so. Officially, the US may not be in recession for months. That kind of announcement usually comes from the White House, but since this a presidential election year, and the party of the sitting president usually is ousted when there’s bad economic performance, the Oval Office will be slow to admit a downturn.

Common in many US homes (and perhaps homes in other countries) is the folding attic stair. More akin to a step ladder than a stair, the device, which folds into the ceiling below an attic, is used to gain occasional access to the space to expand storage options or for maintenance of equipment that might be residing there. The opening for the stair is fairly standard at about 2 feet by 5 and is covered when closed by a sheet of thin plywood attached to the ladder and its spring-loaded closing/opening mechanism.

Cornell patents a pink lily look-alike that blooms all summer long
January 8, 2008 04:32 PM - Cornell University Communications
Mauve Majesty is one cool lily look-alike. This new pinkish-purple ornamental flower, just patented by Cornell, can last for two weeks in a vase, but when left in the garden, it blooms all summer long in the cooler, northern states until the first hard freeze in the fall. The new hybrid of the Inca lily (Alstroemeria), which was developed by a Cornell professor, is a non-fragrant perennial that is set apart by its lavender-lilac flower color (which is adorned with dark speckling and a creamy yellow throat), its strong, upright flower stems and its winter hardiness. In greenhouses, the new hybrid never goes dormant and grows year-round.
