US EIA Reports Record-setting 7% Overall Decline in US Carbon Dioxide Emissions in 2009; Transport Emissions Down 4.1%, Lowest Percentage Reduction of the End-UseSectors

Green Car Congress

In 2009, the carbon intensity of the electric power sector decreased by nearly 4.3%, primarily due to fuel switching as the price of coal rose 6.8% Increased use of natural gas in place of coal caused the sector’s carbon intensity to decrease. The average decline in energy intensity from 2000 to 2008 was 2.0%. Click to enlarge.

EIA: US energy-related CO2 emissions down 2.4% in 2011 while GDP rose

Green Car Congress

The commercial sector fell slightly (0.3%). Because primary energy use in the electric power sector is allocated to the end-use sectors based on their share of electricity use, the drop in reported carbon intensity for the end-use sectors was greatest in the residential and commercial sectors (3.1%

IPCC: GHG emissions accelerating despite mitigation efforts; major institutional and technological change required to keep the heat down

Green Car Congress

giga tonne carbon dioxide equivalent (GtCO 2 eq) (2.2%) per year from 2000 to 2010 compared to 0.4 GtCO 2 eq (1.3%) per year from 1970 to 2000. Total anthropogenic GHG emissions were the highest in human history from 2000 to 2010 and reached 49 (±4.5) Increased use of coal relative to other energy sources has reversed the long?

Shell updates energy scenarios; world entering an era of volatile transitions

Green Car Congress

Underlying global demand for energy by 2050 could triple from its 2000 level if emerging economies follow historical patterns of development. But this still leaves a gap between business as-usual supply and business-as-usual demand of around 400 EJ/a: the size of the whole industry in 2000. Zone of uncertainty. Supply-demand tensions.

China’s New Breeder Reactors May Produce More Than Just Watts

Cars That Think

The new breeder reactors in China, meanwhile, are demonstration projects, the second step in a three-step program to develop fast breeder reactors to reduce the country’s dependence on coal. The country will soon decide whether to continue to the third step of building a commercial 1,000-MW breeder reactor.

Perspective: Despite Solyndra’s death, the future of solar energy is sunny

Green Car Congress

Remember when the dot.com bubble burst in 2000 and, seemingly overnight, some companies ceased making millions hand-over-fist? With subsidies long in place for nuclear, coal and gas in the US along with the cheap cost of production for coal and natural gas, solar is essentially competing with that $0.10/kWh Resources. [
