Honda marked the opening of Honda Smart Home US, showcasing technologies that enable zero net energy living and transportation, including Honda’s home energy management system (HEMS), a proprietary hardware and software system that monitors, controls and optimizes electrical generation and consumption throughout the home’s microgrid.
The home, located on the West Village campus of the University of California, Davis, is capable of producing more energy on-site from renewable sources than it consumes annually, including enough energy to power a Honda Fit EV for daily commuting. Honda Smart Home is expected to generate a surplus of 2.6 MWh of electricity over the course of a year, while a comparable home will consume approximately 13.3 MWh. The home’s occupant will be able to use less than half of the energy of a similarly sized new home in the Davis area for heating, cooling and lighting. The home is also three times more water-efficient than a typical US home.

Toyota Motor Corporation (TMC) has developed a world-first technology for recycling the copper contained in wiring harnesses, in collaboration with Yazaki Corporation (Yazaki), Toyota Tsusho Corporation (Toyota Tsusho), and eight other companies. The newly-developed technology produces copper with a purity of 99.96%.
Roughly 40 years’ worth of mineable copper resources remain worldwide, according to a 2013 report by Japan Oil, Gas and Metals National Corporation (JOGMEC). At the same time, global consumption is growing, driven particularly by infrastructure-related demand for wiring in emerging markets. In addition, large amounts of copper are used in the motors of hybrid vehicles, which are becoming increasingly popular.
Chevy buying carbon credits from US colleges; new formula helps fund campus energy-efficient projects
February 12, 2014
Chevrolet is investing in clean energy efficiency initiatives of US colleges and universities through its voluntary carbon-reduction initiative. The funding opportunity is open to all US universities and colleges; a campus determines whether its performance in reducing carbon emissions will qualify based on new methodologies that Chevrolet developed through the Verified Carbon Standard.
To develop the new methodologies, Chevrolet worked with an advisory team led by the Climate Neutral Business Network with support from the Bonneville Environmental Foundation, the US Green Building Council and the Association for the Advancement of Sustainability in Higher Education (AASHE).

Axens, IFP Energies nouvelles (IFPEN) and Michelin have launched a plant chemistry research partnership that aims to develop and bring to market a process for producing bio-sourced butadiene, or bio-butadiene. Butadiene is a chemical intermediate derived from fossil resources that is used in the production of synthetic rubber. Some 60% of global output is for the tire industry.
In response to the need to find sustainable alternative sourcing channels for elastomers, the BioButterfly process will make it possible to produce innovative, more environmentally-friendly synthetic rubber. The bio-butadiene produced will support continued innovation in procuring high performance rubber for tires.
JRC study finds 8 metals for low-carbon energy technologies at risk of shortages; EVs, wind and solar, and lighting the applications of most concern
November 04, 2013
A new European Joint Research Centre (JRC) study looking into the supply of raw materials for the manufacture of low-carbon energy technologies found that eight metals were at high risk of shortages. The applications, i.e. technologies, of particular concern as a result are electric vehicles, wind and solar energy, and lighting. The risk arises from EU dependency on imports, growing demand worldwide and geopolitical reasons.
The study builds on a 2011 effort which looked into the six key applications of the Strategic Energy Technology (SET) Plan: wind, solar, nuclear fission, bioenergy, carbon capture and storage (CCS) and the electricity grid. In the new study, these were re-assessed and considered along with 11 other technologies—including fuel cells, electricity storage, electric vehicles and lighting—treated in the new report, this time evaluated on the expected supplies of the metals and not on the current situation as in the first report.
Ford expands use of near-dry machining to six plants worldwide

Ford Motor Company has added its near-dry machining process—Minimum Quantity Lubrication (MQL)—to six plants globally, a number that will nearly double in the next few years.
Machining metal pieces generates friction and heat. Conventional wet machining floods the work piece with metal-working fluids, requiring large amounts of fluid to cool and lubricate the cutting tools. MQL eliminates conventional flood coolant from the machining processes, lubricating cutting tools with a fine spray of oil directed exactly when and where it is needed. MQL reduces oil mist generation; biological contamination of coolant; waste water volume; costs for capital equipment; and regulatory permitting. MQL also improves recycling and transport of coolant contaminated chips.

Volkswagen Chattanooga has received a 2013 Green Power Leadership Award from the US Environmental Protection Agency (EPA)—the only automaker to be so recognized. The annual awards recognize the country’s leading green power users for their commitment and contribution to helping advance the development of the nation’s voluntary green power market.
Volkswagen Chattanooga was one of only four organizations nationwide to receive a Leadership Award in the category of on-site generation of green power. (The others were Apple; the County of Santa Clara, CA; and Kaiser Permanete.) The award recognizes EPA Green Power Partners who distinguish themselves using on-site renewable energy applications, such as solar photovoltaic (PV) or landfill gas. Volkswagen Chattanooga is currently generating more than 13 million kWh of green power annually from its on-site 9.5 MW solar energy system, which is enough green power to meet 12% of the organization’s electricity use.

Tesla Motors and SpaceX CEO Elon Musk released the preliminary design study for what he calls “The Hyperloop”—a new high-speed electric transportation system targeted for the the specific case of high-traffic city pairs (e.g., San Francisco and Los Angeles) that are less than about 1500 km or 900 miles apart. (For longer distances, Musk suggests, quiet supersonic air travel would be faster and cheaper.)
Hyperloop—which is an open-source concept, user feedback is welcome—consists of paired partially-evacuated tubes (0.015 psi, 100 Pa), with passenger capsules (or pods) that are transported at both low and high speeds throughout the length of the tube. The capsules are supported on a cushion of air, featuring pressurized air and aerodynamic lift. The capsules are accelerated via a magnetic linear accelerator affixed at various stations on the low pressure tube. Stators are located on the capsules to transfer momentum to the capsules via the linear accelerators.
UPS sets 2017 goal of 1 billion alternative fuel miles
July 27, 2013
UPS released its annual Sustainability Report announcing that while the total number of packages shipped in 2012 increased, the company reduced its total Greenhouse Gas (GHG) emissions. Environmental achievements included ground and air fuel savings, increased investments in alternative fuel vehicles, and retooled routes that shaved 12.1 million miles from ground deliveries.
UPS also set a new alternative fuel goal of one billion cumulative miles (from a baseline of the year 2000) driven by alternative fuel/advanced technology vehicles by 2017, said David Abney, UPS Chief Operating Officer—more than double the previous goal of 400 million miles. Through the end of 2012, UPS has logged 295 million cumulative alternative fuel miles.
