Race to the Bottom: How Renewable Microgrids will Compete with Diesel Power in the Coming Years

September 17, 2015 by Arnaud Henin

Microgrids and Diesel

The fall in oil prices has created a number of knock-on effects for renewable energy and other emerging clean technologies. Some of these effects are clear cut; for example lower gas prices makes the economic case for electric vehicles more difficult. Other impacts are less clear-cut.[read more]

Is Audi's Carbon-Neutral Diesel a Game-Changer?

May 5, 2015 by Robert Rapier

Audi Carbon-Neutral Diesel

Recently German car manufacturer Audi announced they can economically produce carbon-neutral automotive fuel from ingredients found in the atmosphere. Many people have already suspected that there has to be a catch. Of course there is.[read more]

Fuel Economy Standards Drive Down Projected Gasoline Use; Diesel Use, Product Exports Rise

June 27, 2014 by U.S. EIA: Today in Energy

Fuel Economy, Use, and Export

In the EIA's Annual Energy Outlook 2014, more-stringent vehicle fuel economy standards contribute to a decline in motor gasoline consumption through 2040. Growth in heavy-duty vehicle miles traveled is greater than increasing heavy-duty vehicle fuel economy, contributing to rising diesel fuel demand.[read more]

Fuel Choice: Diesel Me This, Diesel Me That

July 26, 2013 by Maximilian Auffhammer

In the summer I often take my family to the home of soccer, beer, and renewables – Germany. The place has changed. The potato fields I used to traverse on my BMX bike are covered in Chinese made Solar PV installations, and there are windmills everywhere.[read more]

Breaking Our Oil Addiction Takes More Than Killing Keystone XL

November 15, 2011 by Geoffrey Styles

In an article in today's Washington Post an official of the National Wildlife Federation was quoted linking rejection of the Keystone XL pipeline with breaking our addiction to oil. Even with the administration having delayed its decision on the project until 2013--quite possibly killing it--this point merits further exploration. Just...[read more]

Deploying Extra Power for Japan

March 29, 2011 by Geoffrey Styles

Just over two weeks after the earthquake near Sendai in northeastern Japan, which I'm increasingly seeing referred to as the "Great Tohoku Earthquake", the impact of the resulting disruption to various supply chains is being felt around the world. From car factories in Europe that rely on Japanese electronic components to producers of...[read more]

UPS turns to LNG, not CNG, for natural gas fueled long-haul trucks

February 25, 2011 by Michael Giberson

The low cost of natural gas and the high cost of petroleum products like diesel and gasoline have produced a lot of interest in natural gas as a transportation fuel. It is an idea that’s been around for a while and works fine in practice. Most of the interest and effort has gone into using compressed natural gas (CNG). UPS recently...[read more]

Diesel Hybrids Arrive

September 8, 2010 by Geoffrey Styles

Regular readers know I'm a fan of diesel cars, having test-driven some terrific models at recent car shows, as well as renting them on past trips to Europe. For drivers who travel mainly highway miles, the fuel economy benefits of dieselization can approach those of hybrids at a much lower initial cost premium. However, at least in the...[read more]

Another natural gas issue

April 16, 2010 by Lou Grinzo

And speaking of using natural gas for transportation (as in part of my earlier post, The true face of shale gas), there’s the whole nasty issue of leaks. Natural Gas May Be Worse for the Planet than Coal: This week the U.S. Congress heard testimony supporting a bill that would push to replace diesel with natural gas in heavy vehicles....[read more]

Super Bowl Diesel

February 8, 2010 by Geoffrey Styles

In addition to a pair of well-matched teams and a sufficient dose of fourth-quarter suspense concerning the outcome, yesterday's Super Bowl was the first in several years to feature an ad meriting comment in an energy blog. The subject of the ad was the new Audi A3 TDI clean diesel car, which was recently named "Green Car of the Year"...[read more]

Prius, Part 2: Why hybrids beat diesels

May 19, 2008 by Joseph Romm

The best thing about the Prius is that it achieves its high fuel economy without sacrificing size or performance and, most importantly for global warming, without being a diesel. There seems to be a lot of confusion on this point in the comments section of Part One, so let me elaborate. Bottom Line: If you care about global warming, don’...[read more]

Diaper-to-Diesel technology... seriously

October 31, 2007 by Tyler Hamilton

My Clean Break column this week is about plans to build a facility in Quebec that will process used diapers into oil, gas and char using a pyrolysis process. Engineering giant AMEC has been contracted to build the plant, which will take in used diapers (infant and adult) from hospitals and seniors homes. It makes sense. Pyrolysis is a...[read more]
