and greenhouse gases vehicles must become dramatically more efficient regardless of how they are powered said Douglas M. Chapin principal of MPR Associates
i e. energy cost savings improved vehicle technologies and reductions in petroleum use and greenhouse gas emissions exceed the additional costs of the transition over and above
Improving the efficiency of conventional vehicles is up to a point the most economical and easiest-to-implement approach to saving fuel
This approach includes reducing work the engine must perform--reducing vehicle weight aerodynamic resistance rolling resistance
The average fuel economy of vehicles on the road would have exceed to 180 mpg which the report says is extremely unlikely with current technologies.
Therefore the study committee also considered other alternatives for vehicles and fuels including: hybrid electric vehicles such as the Toyota Prius;
plug-in hybrid electric vehicles such as the Chevrolet Volt; battery electric vehicles such as the Nissan Leaf;
hydrogen fuel cell electric vehicles such as the Mercedes F-Cell scheduled to be introduced about 2014; and compressed natural gas vehicles such as the Honda civic Natural gas.
Although driving costs per mile will be lower especially for vehicles powered by natural gas or electricity the high initial purchase cost is likely to be a significant barrier to widespread consumer acceptance the report says.
All the vehicles considered are and will continue to be several thousand dollars more expensive than today's conventional vehicles.
Additionally particularly in the early years the report predicts that alternative vehicles will likely be limited to a few body styles and sizes;
some will rely on fuels that are not readily available or have restricted travel range; and others may require bulky energy storage that will limit their cargo and passenger capacity.
Wide consumer acceptance is essential however and large numbers of alternative vehicles must be purchased long before 2050
if the on-road fleet is to meet desired performance goals. Strong policies and technology advances are critical in overcoming this challenge.
The report identified several scenarios that could meet the more demanding 2050 greenhouse gas goal.
Each combines highly efficient vehicles with at least one of three alternative power sources--biofuel electricity or hydrogen.
Natural gas vehicles were considered but their greenhouse gas emissions are too high for the 2050 goal.
However if the costs of these vehicles can be reduced and appropriate refueling infrastructure created they have great potential for reducing petroleum consumption.
While corn-grain ethanol and biodiesel are the only biofuels to have been produced in commercial quantities in the U s. to date the study committee found much greater potential in biofuels made from lignocellulosic biomass
--which includes crop residues like wheat straw switchgrass whole trees and wood waste. This drop in fuel is designed to be a direct replacement for gasoline
it can also be introduced without major changes in fuel delivery infrastructure or vehicles. The report finds that sufficient lignocellulosic biomass could be produced by 2050 to meet the goal of an 80 percent reduction in petroleum use
when combined with highly efficient vehicles. Vehicles powered by electricity will not emit any greenhouse gases
but the production of electricity and the additional load on the electric power grid are factors that must be considered.
These vehicles also rely on batteries which are projected to drop steeply in price. However the report says that limited range
and long recharge times are likely to limit the use of all-electric vehicles mainly to local driving.
When hydrogen is used as a fuel cell in electric vehicles the only vehicle emission is water.
Hydrogen fuel cell vehicles could become less costly than the advanced internal combustion engine vehicles of 2050.
Fuel cell vehicles are not subject to the limitations of battery vehicles but developing a hydrogen infrastructure in concert with a growing number of fuel cell vehicles will be difficult and expensive the report says.
The technology advances required to meet the 2050 goals are challenging and not assured. Nevertheless the committee considers that dramatic cost reduction
The best approach therefore is to promote a portfolio of vehicle and fuel research and development supported by both government
Overcoming the barriers to advanced vehicles and fuels will require a rigorous policy framework that is more stringent than the proposed fuel economy standards for 2025.
and vehicle technologies are close to market readiness and consumer behavior toward them is understood well The report warns that forcing a technology into the market should be undertaken only when the benefits of the proposed support justify its costs.

At the same time their high reactivity has raised concerns about their fate transport and toxicity in the environment.
In the future makers of advanced biofuels might use a similar strategy blending different feedstock varieties to balance the energy characteristics of the transportation fuel they produce.

As electric vehicles (EVS) increasingly enter the market and charging stations are built to serve them EVS are competing with alternative-fuel vehicles.

#Study shows where on the planet new roads should and should not goresearchers have created a'large-scale zoning plan'that aims to limit the environmental costs of road expansion
More than 25 million kilometres of new roads will be built worldwide by 2050. Many of these roads will slice into Earth's last wildernesses where they bring an influx of destructive loggers hunters and illegal miners.
Now an ambitious study has created a'global roadmap'for prioritising road building across the planet to try to balance the competing demands of development and environmental protection.
and a'road-benefits'layer that estimates the potential for increased agriculture production via new or improved roads.
The authors of the new study recently published in the journal Nature write that by combining these layers they have identified areas where new roads have most potential benefit areas where road building should be avoided
but we think we've identified where in the world new roads would be most environmentally damaging said co-author Professor Andrew Balmford from the University of Cambridge's Department of Zoology.
Roads often open a Pandora's box of environmental problems said Professor William Laurance of James Cook University in Australia the study's lead author.
But we also need roads for our societies and economies so the challenge is to decide where to put new roads
--and where to avoid them. Professors Laurance and Balmford worked with colleagues from Harvard Cambridge Melbourne Minnesota
After mapping out the priority areas for conservation the team then tried to decide where roads would have the greatest benefits for humanity.
In general areas that would benefit most from new roads are those that have converted largely to agriculture
and new or improved roads are vital for farmers said Dr Gopalasamy Reuben Clements from James Cook.
With better roads farmers can buy fertilisers to raise their yields and get their crops to markets with far less cost and waste.
Areas with carbon-rich ecosystems with key wilderness habitats such as tropical forests were identified as those where new roads would cause the most environmental damage with the lease human benefit particularly areas where few roads currently exist.
but a very rapidly growing human population that will need more food and more roads. The study's authors say that this new global road-mapping scheme can be used as a working model that can be adapted to for specific areas.
They say that proactive and strategic planning to reduce environmental damage should be central to any discussion about road expansion.
Given that the total length of new roads anticipated by mid-century would encircle the Earth more than 600 times the authors point out that there is little time to lose.
