This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Pollution from ships creates lines of clouds that can stretch hundreds of miles. The difference helps explain how much industrial pollution influences clouds. NASA Earth Observatory.
Based on the law of constant travel time budget, the average travel time elasticity of the amount of kilometres equals -1, (average for all modalities) (Van Wee, 1998; Pfleiderer, 2003). Fuel consumption of a car increases at higher speeds, the main reason being that with increasing speed the wind resistance increases exponentially.
About a third of the airborne lead particles collected at two sites in the San Francisco Bay Area came from Asia, a finding that underscores the far-flung impacts of air pollution and heralds a new way to learn more about its journey across vast distances. They found that a median value of 29% of the lead particles were of Asian origin.
The largest one-year emissions drop California has ever achieved was at the height of the Great Recession in 2009, when climate pollution fell 6.1%. lower than 2008 and 2003, respectively. Data from the report illustrate that California now must reduce emissions by an average of 4.9% lower and 8.3%
For only the second time since PPIC began asking the question in 2003, more Californians support expanding oil drilling off the coast than oppose it (51% favor, 43% oppose), the same as last year (51% favor, 45% oppose). Energy sources and automobile efficiency. Air quality. Californians’ views about air quality have seen a significant shift.
Obama noted that last year, US oil production reached its highest level since 2003 and that for the first time in more than a decade, imported oil accounted for less than half the liquid fuel consumed. We have to discover and produce cleaner, renewable sources of energy with less of the carbon pollution that threatens our climate.
The first two reports dealt with nuclear power (2003) and coal (2007). The introduction of large intermittent power generation from, for example, wind and solar, will have specific short and long term effects on the mix of generation technologies.
But theyve needed definitive proof that PHEVs wont increase pollution. CA, NY, MA and other states have had Zero-Emission Vehicle programs since the early 1990s because battery electric vehicles in those states, taking into account power plants, are far cleaner than gasoline cars in reducing urban air pollution and smog.
I mean, when the electricity it uses is produces, pollution still happens, just not "right from your car"? Neutral Kaitou KID @ Apr 19th 2009 4:45PM not if the electricity is from ultra efficient solar panels, hydroelectric dams or wind. Low Ranked richii @ Apr 19th 2009 4:29PM for some reason this makes me think of the future.
Despite this, a 2003 EPRI study , assuming only $2/gallon gas , zero buying incentives, and a PHEV premium of $3-$5,000 more than standard hybrids, shows that the total lifetime cost of ownership for a PHEV will be lower than that of any other vehicle type -- so the payback will be there. How about a car-mounted wind-generator?
The latest series of tests conducted by the DEKRA E-Mobility Competence Center were extensive—ranging from how a car might catch fire, how the flames might spread and what would be required to extinguish the fire, to the pollution caused by run-off of the water used for fighting the fire.
