The Case for Nuclear Cargo Ships

Cars That Think

The shipping industry has been trying to cut its carbon emissions for years, and with little to show for it. Nearly all of the world’s ship fleet still runs on diesel fuel, with about a quarter of new ships on order being built to run on somewhat lower-carbon alternatives like liquefied natural gas, methanol, or hybrid propulsion.

Study finds that worldwide SO2 emissions rose between 2000-2005 after decade of decline; China, shipping topped growth

Green Car Congress

Global sulfur dioxide (SO 2 ) emissions peaked in the early 1970s and decreased until 2000, with an increase in recent years due to increased emissions in China, international shipping, and developing countries in general, according to a new analysis appearing in the open access journal Atmospheric Chemistry and Physics.

ExxonMobil: global GDP up ~140% by 2040, but energy demand ~35% due to efficiency; LDV energy demand to rise only slightly despite doubling parc

Green Car Congress

ExxonMobil focused particularly on three groups of countries in projecting future energy trends: China and India, which are expected to account for half the growth in global energy demand because these two developing economies will lead the world in terms of population size and the pace of growth in standards of living.

Study of lead isotopes provides insight into aerosols transport from Asia to US

Green Car Congress

The team used the lead particles’ isotopic signature to trace some of the lead’s origins to coal and metal ore found only in Asia. “ But the details of this transport, such as that of the lead particles’ 7,000-mile journey from the smokestacks of China to the west coast of North America, are largely unknown.

EIA: light duty vehicle energy consumption to drop 25% by 2040; increased oil production, vehicle efficiency reduce US oil and liquid imports

Green Car Congress

Energy consumption by marine vessels increases from 0.9 Natural gas overtakes coal as the largest fuel for US electricity generation. In some areas, natural gas-fired generation replaces power formerly supplied by coal and nuclear plants. Personal air travel (billion seat-miles) grows by an average of 0.7% billion metric tons.
