Radiative forcing due to perpetual constant year 2000 emissions grouped by sector for 2020 (left) and 2100 (right) showing the contribution from each species. The net sum of total radiative forcing is indicated by the title of each bar. From Unger et al., PNAS. Click to enlarge. A new study by led by Nadine Unger at NASA’s Goddard Institute for Space Studies (GISS) that analyzes the net climate impacts of emissions from economic sectors rather than by individual chemical species has found that o

A multi-Hubbert analysis of coal production by Tadeusz Patzek at The University of Texas at Austin and Gregory Croft at the University of California, Berkeley concludes that the global peak of coal production from existing coalfields will occur close to the year 2011. The HHV of global production is likely to peak in 2011 at 160 EJ/y, and the peak carbon emissions from coal burning will also peak in 2011 at 4.0 Gt C (15 Gt CO 2 ) per year, according to the study.

In a speech at the National Press Club, US Energy Secretary Steven Chu said that the success of China and other countries in clean energy industries represents a new “Sputnik Moment” for the United States, and will require a similar mobilization of innovation to enable the US to compete in the global race for the jobs of the future. Secretary Chu observed that China’s investments in clean energy technologies represent both a challenge and an opportunity for the United States.

Sanyo Electric recently announced an agreement with Suzuki Motor to supply lithium-ion battery systems for the Swift Plug-in Hybrid. ( Earlier post.) Suzuki has already announced its intention to start manufacturing the vehicles. The plug-in is powered by a 55 kW, 180 N·m AC synchronous motor and a 2.66 kWh Li-ion battery pack. The 0.66L engine is the K6A, earlier versions of which were used in the Cappuccino.

Environmental burden of a gasoline-fueled ICEV relative to that of a BEV (100%) assessed by four different methods: abiotic depletion potential (ADP), nonrenewable cumulated energy demand (CED), global warming potential (GWP), and Ecoindicator 99 H/A (EI99 H/A). Credit; ACS, Notter et al. Click to enlarge. A team from the Swiss Federal Laboratories for Materials Science and Technology (Empa) compiled a detailed lifecycle inventory of a Li-ion battery and produced a rough lifecycle analysis (LCA)
