The California Air Resources Board (CARB) announced that greenhouse gas emissions in California in 2016 fell below 1990 levels for the first time since emissions peaked in 2004—a reduction roughly equivalent to taking 12 million cars off the road or saving 6 billion gallons of gasoline a year.
A study by the University of California, Riverside College of Engineering Center for Environmental Research and Technology (CE-CERT) found that a Los Angeles County Metropolitan Transit Agency (Metro) bus equipped with an ultra-low emission natural gas engine performs significantly cleaner than its certification standards across all duty cycles.
The Energy Department’s National Renewable Energy Laboratory (NREL) recently released a long-anticipated update to the source-of-record for cetane number data. The cetane number is typically measured either in a single-cylinder engine or a constant-volume combustion chamber. The original report has been cited more than 130 times.
The analysis updates EPRI’s 2004 EPRI assessment, which estimated the cost of implementing a smart grid at $165 billion. The Smart Grid will allow the benefits resulting from the rapid growth of renewable power generation and storage as well as the increased use of electric vehicles to become available to consumers.
million in Federal Transit Administration (FTA) and California Proposition 1B Bond funds to replace fifty 40-foot New Flyer buses purchased between 2004 and 2006. In 2015, Big Blue Bus became one of the country’s first municipal transit agencies to convert its entire fleet to renewable natural gas (RNG). Earlier post.).
Drop-in alternative fuels will require no significant modifications to aircraft and engines and with a goal of performing more efficiently, and cleaner than current fossil-based fuels. Safety and transition strategies that enable “drop in” replacement for petroleum-derived aviation fuels.
In effect, the market of rechargeable lithium batteries will undergo a quantum leap forward in the adoption of state of the art renewable energy technology. This will contribute to cleaner air quality in the major urban areas of China. —Huw Hampson-Jones, OXIS CEO. It has been granted 79 patents with 93 pending.
Because of their relatively low cost, high performance, and ability to utilize renewable fuels, internal combustion engines—including those in hybrid vehicles—will continue to be critical to our transportation infrastructure for decades.
2 Plug-in hybrids are cleaner 3 Plug-in hybrids are cheaper 4 Plug-in hybrids are domestic 5 Plug-in hybrids already exist 1. So youll have a cleaner, cheaper, quieter car for your local travel, and the gas tank is always there should you need to drive longer distances. What Are Plug-In Hybrids? You dont have to plug it in.
This article discusses: (a) why the focus should have been on the transfer of proven renewable energy technology from developed to developing countries; and (b) how this technology transfer can be financed with currently available funds. What cannot be argued is the fact that fossil fuels are non-renewable. Obstacles to Licensing.
Since its launch in 2011, the regulation has generated a multitude of unique approaches for cleaner fuels. California’s vehicle GHG standards—authorized by AB 1493 (Pavley) in 2002, first approved in 2004, and extended in 2012—are delivering fuel consumption and CO 2 reductions.
