Oil demand grew by less than 1%—the slowest rate amongst fossil fuels—while gas grew by 2.2%, and coal was the only fossil fuel with above average annual consumption growth at 5.4% Coal was again the fastest growing fossil fuel with predictable consequences for carbon emissions; it now accounts for 30.3% globally, and 8.4%
Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT. The first two reports dealt with nuclear power (2003) and coal (2007).
In 2003 JEC issued its first Well-to-Wheels study, a type of analysis which takes into account the entire energy lifecycle of fuels and powertrains and their possible combinations. Producing synthetic gas (SNG) from wind electricity (e.g., High quality diesel fuel can be produced from natural gas (GTL) and coal (CTL).
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. “ The team’s research could help scientists improve computer models that describe how dust-sized aerosols such as air pollution ride the winds across continents and oceans. —John Christensen.
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. Now, in light of ongoing events in Japan, I want to say another word about nuclear power.
Plug-In Hybrids Are Cleaner (Even on a Coal Grid) [ to top ] This entire section is finally obsolete -- because we now have a definitive study by the Electric Power Research Institute and the Natural Resources Defense Council. In some areas where wind and hydropower is wasted at night, the rate can be as low as 2-3 cents per kWh.
Neutral Kaitou KID @ Apr 19th 2009 4:45PM not if the electricity is from ultra efficient solar panels, hydroelectric dams or wind. Highly Ranked catachip @ Apr 19th 2009 4:57PM @ Elodie As long as the electricity is generated from wind, hydro, solar, or nuclear then there are zero emissions. excluding coal power in china.
Sorry, but electrics and electric power plants are so efficient that CO2 emissions are less than gassers even when the electricity comes from coal - and a lot of electricity doesnt come from coal. In California, 20% of our electricity comes from zero CO2 renewables (sun, wind, geothermal), another 20% from zero CO2 hydro, and only 20.1%
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?
Spiking demand for electric heat collided with supply problems created by frozen natural-gas equipment and below-average wind-power production. Similar mismatches in supply and demand contributed to massive cascading blackouts in August 2003 in the northeastern United States and Canada, in July 2012 in India , and in March 2019 in Venezuela.
Wang entered the automobile business in 2003 by buying a Chinese state-owned car company that was all but defunct. His people at MidAmerican have studied clean technologies like batteries and wind power for years because of the threat of climate change. He knew very little about making cars but proved to be a quick study.
