An analysis of the US refining sector, based on linear programming (LP) modeling, finds that refining plausibly high volumes of Canadian oilsands crudes in US refineries in 2025 would lead to a modest increase in refinery CO 2 emissions (ranging between 5.4% to 9.3%) from a 2010 baseline, depending upon the supply scenario.
A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oilsands and oil shale) alongside shale gas, coal, lignite, wood and conventional oil and gas. This is not the same as crude oil occurring naturally in shales, as in the Bakken.
Comparison of the percent differential for WTW (well-to-wheel) GHGs from gasoline produced from WCSB oilsands using different production processes relative to gasoline produced from reference crudes. The proposed Project is not likely to impact the amount of crude oil produced from the oilsands. Click to enlarge.
The five different fuel groups were those derived: from conventional petroleum; from unconventional petroleum; synthetically from natural gas, coal, or combinations of coal and biomass via the FT process; renewable oils; and alcohols. Certain HRJ and FT fuels are able to reduce the GHG emissions from aviation. million bpd.
In contrast to arguments that peak conventional oil production is imminent due to physical resource scarcity, a team from Stanford University and UC Santa Cruz has examined the alternative possibility of reduced oil use due to improved efficiency and oil substitution. 2010, to above 140 $/bbl in constant 2010 dollars).
Building on LCFS policies already adopted in Europe, British Columbia, and California, the researchers looked at potential costs and benefits of reducing the carbon intensity of transportation fuels by 10 to 15 percent by 2030. Create separate fuel pools for gasoline and diesel. We did not shy away from controversy.
However, you should not delay inclusion of known sources of emissions, including indirect emissions from biofuels, pending discovery of potential effects from other fuels. To spur innovation in low carbon fuels, the LCFS must send an accurate signal to the growing clean energy market.
Direct injection and flex fuels require a more robust valvetrain system due to the increased friction, higher thermal loads, increased oxidation and reduced lubrication associated with alternatefuels that do not contain some of the natural lubricants found in gasoline.

To maximize performance and efficiency there are five driver selectable drive modesConserve, Normal, Excite, Slippery and Snow/Sand. The Environmental Protection Agency, EPA , rates fuel economy at 33 highway and combined when running in hybrid mode only. There is a sixth mode of Preserve, which saves the battery charge for later use.
To maximize performance and efficiency there are five driver selectable drive modes of Conserve, Normal, Excite, Slippery and Snow/Sand. The Environmental Protection Agency rates the Corsair’s fuel economy at 33 mpg highway and combined when running in hybrid mode only. News: 2022 Range Rover Line-up. kilowatt-hours/kWh).
Running on 87 octane, the front wheels (all-wheel drive is not available) are driven through a Continuously Variable Transmission (CVT) that has five driver selectable drive modes of Eco, Normal, Sport, Slippery and Snow/Sand. The Environmental Protection Agency, EPA , rates fuel economy at 40 highway when running in gasoline mode only.
If you consider buying one, make sure you plan on spending time off-pavement seeking sand, mud and snow, as its DNA is far different from any other SUV on the market. But when including the electric range of 21 miles, the city and highway combined number is 49 mpge. A More Efficient (And Quiet) Propulsion System.
The “wet” part of a DCT means it uses oil to improve lubrication and cooling. A “dry” DCT does not use oil, but is the more fuel efficient of the two types. That is joined by exterior colors of Hampton Gray, Phantom Black, Sage Gray, Ice White and Mojave Sand. A torquey turbo four. Pricing and Warranties.
Folks who quote the math of the old system like a well memorized mantra are limited by the notion that no other system will ever exist, while in fact, super capacitive storage systems currently use higher voltages, in the 3000 volt range and rising, to attain larger power transfers, faster, and on lighter wiring!
The new Ecotec portfolio will include 11 engines, with three- and four-cylinder variants ranging from 1.0L —including turbocharged versions—and power ratings ranging from 75 horsepower (56 kW) to 165 horsepower (123 kW), and torque ranging from 70 lb-ft (95 N·m) to 184 lb-ft (250 N·m).
Price tag: about $25,000, made from 95% recyclable materials with a top speed of 65 miles per hour and range of 110 miles per charge. As soon as someone comes up with all day range (300 miles plus) or quick charge capability (less than 30-60 minutes) for a reasonable price (25k - 40k), electric cars will start to take over.
