Fuel Economy Factors - Part 1: The Role of Aerodynamic "Drag"

This is a guest post from Will Stewart. Will is a systems engineer in the DC area and previously has written several guest posts on The Oil Drum, including a series on Passive Solar Design.

As oil production falls and volatile oil prices in concert with a struggling economy induce a pattern of demand suppression/destruction, mobility choices will narrow and Vehicle Miles Traveled (VMT) will decline. What should governments at all levels be proactively preparing for? What should individuals and their families be preparing for in advance? The choices are broad: at a high level, land use planners could refine cities into a series of compact, carfree urban districts interconnected with mass transit. For the existing built-out suburban and exurban communities, however, such choices are limited. Aside from telecommuting, transportation choices will increasingly include biking, carpooling/vanpooling, bus rapid transit, and other efficient means of transportation. Travel between cities and countries will also undergo a transformation, with air travel becoming less and less affordable.

This series will cover current and projected land-based vehicle energy efficiency and a high level overview of the factors that determine it, such as aerodynamic drag, weight, efficiency of motive force (e.g., engine, motor), rolling resistance, driver behavior, drivetrain losses, parasitic losses, environmental factors, Passenger Miles Traveled (PMT), etc. In this first article of the series, we will focus on energy losses associated with aerodynamic drag losses, or more succinctly, “drag”.

The Future of European Transport: iTREN-2030

On 21 October the final workshop was held in Brussels (Belgium) of the integrated transport and energy baseline until 2030 (iTREN-2030) modeling project. At the workshop a final scenario was presented that incorporated likely transport and energy policies, and the effects on European transport of a continued global plateau in oil production up to 2030. The integrated scenario was generated by four energy and transport models that have been linked in iTREN-2030 to increase the forecasting power of the transport policies of the European Commission.

In this post I describe the iTREN-2030 project and the different models, covering the POLES global energy supply and demand model in more detail, highlight the conclusions of the present integrated scenario, and give my reflection on the workshop commenting on some areas of improvement to augment the potential of the models.

The iTREN-2030 project is all the more important because the resulting model set and integrated scenario will be used by the European Commission (DG-Tren) in preparing the white paper on transport policies due for 2010. After discussion with the European Parliament and approval by the council of Minister, the European Union will as a result have set out its new course for the future of transport in the period up to 2020.

The Yike bike - is the future of urban transport a folding, electric, penny farthing ?

A friend of mine sent in a link to this new electric bike concept from New Zealand - the YikeBike. Its a little expensive at the moment (though not compared to a high-end road bike or mountain bike I guess).

Road.cc has a review - Yike bike - is the future a folding, electric, penny farthing?.

Let's play a word association game: electric bike, penny farthing, folder, carbon fibre, Porsche… hard to build a mental image from that lot, but one day… that list will immediately make you think “Yike Bike”. Maybe.

What we have here is a folding electric bike that weighs less than 10Kg with a range of about 10Km and that is as easy to charge as a laptop and not that much bigger when folded, which the team behind it hope will one day be the transport of choice of the style-conscious buisnessman or urban commuter for the short hops from penthouse apartment to downtown office. And as for the “Yike” – well, that's what you say the first time your ride it, or at least the cleaned-up version.

Obesity, Land Use, Transportation and Healthcare Reform

A few weeks ago on a family vacation I made a pit stop along one of I-95’s fast-food dominated rest areas. I stood in horror at the sheer size of the people ambling out of their SUVs to load up on burgers, soda and fries. They were beyond just overweight or “fat”. I would say about half were morbidly obese. It was the intersection of our nation’s problems with automobiles, industrial food system and poor land use policies, all of which produced people that could barely manage to walk across the parking lot to load up on more empty calories.

Transport and adaptive capacity: An integrated approach to UK policy evaluation

This is a guest post from Robin Lovelace (lovelacerobin@yahoo.com), a graduate student at the University of York, UK. As part of his Environmental Science and Management MSc Robin was asked to pick a policy area and discuss how it could adapt to climate change. Due in part to the Oil Drum, he decided to include peak oil in the discussion, with a reluctant ‘OK’ from Professor Mike Ashmore. Robin is a qualified bicycle mechanic, writing part-time for Interclimate, starting an interdisciplinary PhD in energy research next year and wants to save the world.

Peak Oil On The Campaign Trail: The Black Hole Of Rail Funding

It's election time in New Zealand and Finance Minister Michael Cullen has mentioned Peak Oil in a campaign speech he gave on Wednesday, decrying the state of funding for rail transport and declaring "a new era in the rail industry".

Given the energy challenge we face in coming years, the so-called black hole of rail funding looks more like a pot-hole that urgently needs filling.

In 1908 our predecessors built the North Island Main Trunk line because they had a vision for a much more populous New Zealand and for opening up the North Island to settlement and economic development. The Main Trunk justified the faith of the settlers for more than 50 years, before the rise of road and air transport – helped by cheap oil prices – diminished its role as a carrier of both freight and passengers.

Today we have to come to terms with a new set of circumstances – the emerging reality of Peak Oil and the impact rising fuel prices have on our economy. Rail's energy efficiency has a new relevance and a new importance.

Don’t miss the bus, Mr Rudd

This is a guest post from Community Action for Sustainable Transport Inc

Reducing the fuel excise and Federal investment in roads will not make travel affordable.

This is the message coming from a coalition of more than 20 transport and environmental groups who have signed off on an open letter to PM Kevin Rudd (see below), urging the Federal government to invest heavily in public transport to reduce the impacts of rising petrol prices.

“The Federal government’s urban transport priority must be to create a public transport system that takes people where they need to go, when they need to be there. More than anything else we need better alternatives to the car,” said Tristan Peach, spokesperson for Community Action for Sustainable Transport QLD (CAST).

Short shrift for the Long Paddock

The SMH had an interesting piece on the possible demise of the "Long Paddock" - land reserves for stockmen to move livestock around the country on foot. While it is rarely used nowadays, the land reserved for this use has a lot of environmental value - and (for those of a reversalist bent) they could possibly be revived one day if moving stock around by foot becomes the most energy efficient means of transportation to the markets - something the Queensland government seems to believe (it also maintains a website tracking rural climate issues using this name).

Australia’s Oil-Based Energy Security

This is the first in a series of posts co-authored with Phoenix and Matt Mushalik. In my previous post I took a high-level look at solutions for Australia. This post starts the process of iterating down from the high-level view. It assumes that we will not be able to instantly convert to sustainable solutions - we need to get there in steps. This article is co-authored with Phoenix, a qualified mechanical engineer who has been working in the infrastructure construction industry for over 28 years. He has held senior manangement positions with a number of organisations delivering projects to key energy providers. These projects have included oil refineries, power stations, LNG plants and gas processing facilities. He currently works as the National Manager – Power Generation for a major Australian construction group.

1.0 INTRODUCTION: THE IMPORTANCE OF TRANSPORT

Transport is critical to the functioning of our society. If Australia’s transportation stopped tomorrow, then most of us would be starving in the dark a few weeks later.

Yet this is exactly the scenario that is emerging. The vast majority of transport in Australia is fuelled by oil. Without oil, transport stops. And we are being warned from every direction that our oil supplies are no longer secure.

This scenario will be the most serious threat experienced by our society since the Second World War. This is the first in a series of discussions that look at ways to secure Australia’s oil based energy security into the future. Over the next few weeks we will look at short and long term goals for personal and industrial transport.
