Transport Energy Efficiency

Even if some energy sources are extracted far from where they are consumed, the massification of transportation enables their mobility, particularly for petroleum and coal. Throughout the history of energy use , the choice of an energy source depended on several utility factors that involved a transition in energy systems from solid, liquid, and eventually to gas sources.

Since the industrial revolution, efforts have been made for work to be performed by machines , which considerably improved industrial productivity. The energy sources used for this mechanization substantially impacted energy demand patterns.

The development of the steam engine and the generation and distribution of electric energy over considerable distances have also altered the spatial pattern of manufacturing industries by liberating production from a direct connection to a fixed power system.

While in the earlier stages of the industrial revolution, factories located close to sources of energy a waterfall or a coalfield or raw materials, mass conveyances, and new energy sources petroleum and electricity enabled much greater locational flexibility. Industrialization placed considerable demands on fossil fuels through its processes and outcomes.

At the turn of the 20th century, the invention and commercial development of the internal combustion engine, notably in transport equipment, expanded the mobility of passengers and freight and incited the development of a global trade network.

The setting of industrial and energy systems is interrelated. With globalization, transportation accounts for a growing share of the total energy spent on implementing, operating, and maintaining the international range and scope of economic and social activities.

The benefits conferred by additional mobility, notably in terms of better comparative advantages and resource access, have required a growing amount of energy to support this expanded spatial system.

At the beginning of the 21st century, the transition reached a stage where fossil fuels , such as petroleum, dominate. Transportation and energy can be seen from a cost-benefit perspective, where giving momentum to a mass passengers, vehicles, cargo, etc.

requires a proportional amount of energy. The matter is how effectively this energy is captured to practical use , which has a strong modal characteristic. The relationship between transport and energy is direct but subject to different interpretations since it concerns different transport modes, each having its utility and level of performance.

There is often a compromise between speed and energy consumption related to the desired economic returns. Passengers and high-value goods can be transported by fast but energy-intensive modes since the time component of their mobility tends to have a high value, which conveys the willingness to use more energy.

Economies of scale, mainly those achieved by maritime transportation, are linked to low energy consumption per unit of mass transported but at a slower speed.

This fits freight transport imperatives relatively well, particularly for bulk, where time is less critical and buffer stock can be accumulated. Comparatively, air freight has high energy consumption levels linked to high-speed services with limited buffer stocks.

The transportation market has a broad spectrum of energy consumption, which is particularly impacted by three issues:. The impacts of transport on energy consumption are diverse, including activities that are necessary for the provision of transport infrastructures and facilities:.

Further distinctions in the energy consumption of transport can be made between the mobility of passengers and freight, relying on different modal configurations:. Almost all transportation modes depend on variations of the internal combustion engine , with the two most salient technologies being the diesel engine and the gas turbine , since they are the linchpin of globalization.

While ship and truck engines are adaptations of the diesel engine, jet engines are an adaptation of the gas turbine. While the use of petroleum for other economic sectors, such as industrial and electricity generation, has remained relatively stable, the growth in oil demand is mainly attributed to the growth in transportation demand.

Still, the share of oil used in the transportation sector is steadily declining with the introduction of alternative sources such as electric cars. What varies is the type and quality of petroleum-derived fuel being used. While maritime transportation relies on low-quality bunker fuel, air transportation requires Jet-A, a specialized fuel with additives.

The chemical combustion principle of hydrocarbons is worth looking at. For the majority of internal combustion engines, gasoline C8H18; four strokes Otto-cycle engines serves as fuel, but other sources like methane CH4; gas turbines , diesel mostly trucks , bunker fuel for ships , and kerosene turbofans of jet planes are used.

Gasoline produces around 46, Btu per kilogram combusted, requiring 16 to 24 kg of air. The energy released by combustion causes a rise in the temperature of combustion products.

Several factors and conditions influence the level of combustion in an internal combustion engine to provide momentum and keep efficient operating conditions.

The temperature attained depends on the rate of release and dissipation of the energy and the number of combustion products. Air is the most available source of oxygen, but because air also contains vast quantities of nitrogen, nitrogen becomes the principal constituent of combustion products.

The combustion rate may be increased by finely dividing the fuel to increase its surface area and, hence its reaction rate and mixing it with the air to provide the necessary amount of oxygen.

If combustion were perfect, emissions and thus local environmental impacts of transportation would be negligible, except for carbon dioxide emissions. The challenge is that combustion in internal combustion engines is imperfect and incomplete for two reasons:.

In addition to the imperfect and incomplete combustion of hydrocarbons, three major factors influence the rate of combustion and thus emissions of pollutants, which are the characteristics of the vehicle where technological improvements can play a role , driving characteristics where planning and regulation can play a role , and atmospheric conditions.

The internal combustion engine converts less than a third of the energy consumed into momentum, primarily due to friction. The extent to which conventional non-renewable fossil fuels will continue to be the primary resource for nearly all transportation fuels is subject to debate.

But the gap between demand and supply, once considerable, is narrowing , an effect compounded by the possibility that global oil production will eventually peak. The steady surge in demand from developing economies, particularly China and India, requires additional outputs.

This raises concerns about the capacity of major oil producers to meet this rising and enduring global demand. The producers are not running out of oil, but the existing reservoirs may not be capable of producing on a daily basis the increasing volumes of oil that the world requires.

Reservoirs do not exist as underground lakes from which oil can easily be extracted. There are geological limits to the output of existing fields. This suggests that additional reserves need to be found to compensate for the declining production of existing fields.

Reserves additions may not be enough to offset this growing demand, but technological improvements allowed to tap bitumen and oil shale reserves. However, extracting such reserves necessitates much energy and water.

Others argue that the history of the oil industry is marked by cycles of shortages and surpluses. The rising price of oil will render cost-effective oil recovery in difficult areas.

Deepwater drilling and extraction from tar sands and oil shale should increase the supply of oil that can be recovered and extracted. Still, there is a limit to the capacity of technological innovation to find and extract more oil around the world, and the related risks can be very high.

Adding oil extraction, distribution, and refinery capacity is slow, complex, capital-intensive, and highly regulated. If technically and economically viable, carbon sequestration in CO2 capture and storage could enhance oil recovery from conventional wells and prolong the life of partially depleted oil fields well into the next century.

High fuel prices usually stimulate the development of alternatives, but automotive fuel oil demand is relatively inelastic. Higher prices result in very marginal changes in demand for fuel. Evidence suggests that higher oil prices had a limited impact on the average annual growth rate of global motorization.

The analysis of the evolution of the use of fossil fuels suggests that in a market economy, the introduction of alternative fuels is leading to an increase in the global consumption of both fossil and alternative fuels and not to the substitution of crude oil by alternative fuels.

This suggests that in the initial phase of an energy transition cycle, introducing a new energy source complements the existing supply until the new energy source becomes price competitive to be an alternative. The presence of renewable and non-renewable fuels stimulates the energy market with the concomitant increase in greenhouse gas emissions.

The production of alternative fuels adds up to the existing fossil fuels and does not replace them. The main concern is the amount of oil that can be pumped to the surface on a daily basis, especially where major oil fields have reached peak capacity.

Under such circumstances, oil prices are bound to rise in the medium to long term, sending significant price signals to the transport market.

How the transport system responds and adapts to higher energy prices is subject to much debate and interpretation in terms of the scale and timing of the transition. The following potential consequences can be noted:. Higher energy prices can trigger notable changes in usage, modes, networks, and supply chain management.

From a macro perspective, and since transportation is a very complex system, assessing the outcome of higher energy prices remains hazardous. What appears very likely is a strong rationalization, a shift towards more energy-efficient modes, as well as a higher level of integration between modes to create multiplying effects in energy efficiency.

As higher transport costs play in, namely for containers , many manufacturing activities will reconsider the locations of production facilities to sites closer to markets near-sourcing. While cheap and efficient transport systems favored globalization, the new relationships between transport and energy will likely restructure the global structure of production and distribution towards regionalization.

This process is also favored by less acute differences in labor costs and a push toward automation. The energy source with the lowest cost is usually preferred. The dominance of petroleum-derived fuels results from the relative simplicity with which they can be stored and used in internal combustion engines.

Other fossil fuels natural gas, propane, and methanol can also be used as transportation fuels but require a more complicated storage system.

The main issue concerning the large-scale uses of alternative vehicle fuels is the significant capital investments required in distribution facilities compared with conventional fuels. Another issue is that in terms of energy density , these alternative fuels have lower efficiency than gasoline and thus require a greater volume of onboard storage to cover the equivalent distance as gasoline-propelled vehicles if performance is kept constant.

Alternative fuels in the form of non-crude oil resources are drawing considerable attention due to the non-renewable character of fossil fuels and the need to reduce emissions of harmful pollutants and carbon.

The most prevalent alternatives being considered are:. The diffusion of non-fossil fuels in the transportation sector has serious limitations. While oil prices have increased over time, they have been subject to significant fluctuations.

The comparative costs of alternative energy sources to fossil fuels are higher in the transportation sector than in other types of economic activities.

This suggests higher competitive advantages for the industrial, household, commercial, electricity, and heat sectors to shift away from oil and to rely on solar, wind, or hydro-power. Transportation fuels based on renewable energy sources might not be competitive with petroleum fuels unless significant energy price increases coupled with substantial technological improvements.

A risk concerns the imposition of specific fuels through regulations causing disruptions in capacity and cost. Energy should be a resource available in abundance and effectively managed. If energy becomes scarce, particularly through policy, a whole array of opportunities may be lost, including those related to lower mobility levels.

An emerging trend involves decarbonizing transport intending to make transportation systems carbon neutral. Achieving such an outcome requires measures advocated for decades, such as low-carbon fuels, vehicle and equipment efficiency, and modal shift. It remains unclear if carbon-neutral transportation is achievable in the medium term since it involves capital-intensive energy transitions.

Modes such as maritime shipping have a much lower potential, mainly for technical reasons, as ship engines are massive. Technology other than the internal combustion engine cannot readily provide this power level. Urban transportation with a shorter lifespan of vehicles and a reliance on public transit has a better potential to become carbon neutral.

There are four types of physical work related to human activities: Modification of the environment. Activities involved in modifying the landscape to make it suitable for human activities, such as clearing land for agriculture, modifying the hydrography irrigation , constructing infrastructures such as roads, and building and conditioning temperature and light enclosed structures.

Appropriation of resources. Involves the extraction of agricultural resources from the biomass and raw materials minerals, oil, lumber, etc. for human needs. It also includes waste disposal, which is, in advanced economies, very work-intensive to dispose of safely e.

collection, treatment, and disposal. Processing resources. Concerns the modification of products from biomass, raw materials, and goods to manufacture according to economic needs.

Since the Industrial Revolution, work related to processing resources was considerably mechanized, initially with simple machines, then assembly lines, and currently with automation.

The mobility of passengers and freight aims to attenuate the spatial inequalities in the location of resources and markets by overcoming distance. The lower the energy costs per ton or passenger-kilometer, the less transportation is an economic burden.

Overcoming space in a global economy requires a substantial amount of energy and has consequently been subject to economies of scale. Vehicles and terminal equipment consume energy, while cargo needs to be bundled, sorted, and unbundled.

Transportation and Energy Consumption Transportation and energy can be seen from a cost-benefit perspective, where giving momentum to a mass passengers, vehicles, cargo, etc.

The transportation market has a broad spectrum of energy consumption, which is particularly impacted by three issues: The price level and volatility of energy sources are dependent on the processes used in fuel production.

Stable energy sources are preferred as they enable long-term investments in transportation assets and a constant market supply. Volatile energy prices are not contingent on investments in transport technology.

Technological and technical changes in the level of energy performance of transport modes and terminals. An important goal is thus to improve this energy performance since it is linked with direct economic benefits for operators lower operating costs and users lower rates.

Technological improvements allow access to new motive technologies such as electric vehicles and automation. Environmental externalities related to energy use by transport modes, particularly their emissions. Externalities are conducive to regulations related to using specific modes and energy sources and the goal of reducing them.

The impacts of transport on energy consumption are diverse, including activities that are necessary for the provision of transport infrastructures and facilities: Vehicle manufacture, maintenance, and disposal. The energy spent on manufacturing and recycling vehicles is a direct function of vehicle complexity, the material used, fleet size, and vehicle life cycle.

Assembling a ship can take up to two years and requires substantial materials and energy consumption. Vehicle operation. Mainly involves energy used to provide momentum to vehicles, namely as fuels , as well as for intermodal operations at terminals.

The fuel markets for transportation activities are well-developed. Infrastructure construction and maintenance. Building roads, railways, bridges, tunnels, terminals, ports, and airports and providing lighting and signaling equipment require substantial energy.

They directly relate to vehicle operations since extensive networks are associated with large amounts of traffic. Management of transport operations. The expenses involved in planning, developing, and managing transport infrastructures and operations require time, capital, and skill that must be included in the total energy consumed by the transport sector.

Because transportation is not well-addressed by the proposed cap-and-trade schemes and thus stands to lag behind other sectors despite large opportunities for low-cost emissions reduction, climate legislation should set separate emissions targets for transportation and establish a framework for achieving those targets.
