EIA: CO2 emissions from US power sector have declined 28% since 2005

Green Car Congress

The power sector has become less carbon-intensive as natural gas-fired generation displaced coal-fired and petroleum-fired generation and as the noncarbon sources of electricity generation—especially renewables such as wind and solar—have grown. In 2005, noncarbon sources accounted for 28% of the US electricity mix.

Global Wind Power Capacity Grew 28.8% in 2008; 120.8 GW Total

Green Car Congress

Global wind energy capacity grew by 28.8% GW at the end of 2008, according to the Global Wind Energy Council. More than 27 GW of new wind power generation capacity came online in 2008, 36% more than in 2007. New US wind energy installations totalled 8,358 MW for a total installed capacity of 25,170 MW.

EIA: US energy-related CO2 fell by 2.8% in 2019, slightly below 2017 levels

Green Car Congress

Overall, US energy-related CO 2 emissions have fallen 15% from their peak of 6,003 MMmt in 2007. in 2019, but power sector CO 2 emissions fell by even more (-8.2%), largely because of increases from renewable sources such as wind and solar. Total net electricity generation fell by 1.5%

Study links air pollution and cyclone intensity in Arabian Sea; suggested solutions include diesel filters and two-stroke engines running on LPG fuel

Green Car Congress

Historically, prevailing wind shear patterns prohibit cyclones in the Arabian Sea from becoming major storms. The Nature paper suggests that weakening winds have enabled the formation of stronger cyclones in recent years—including storms in 2007 and 2010 that were the first recorded storms to enter the Gulf of Oman.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

This article shows that including offsets in climate change legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. Assuming the offset is legitimate—i.e.,

California 2017 GHG inventory shows 1.2% total drop from 2016; transportation sector emissions up 1%

Green Car Congress

Emissions from transportation sources were relatively constant from 2002 through 2007, declined through 2013, then increased by 9.0 In-State Hydro, Solar, and Wind Electricity Generation. The transportation sector represents tailpipe emissions from on-road vehicles and direct emissions from other off-road mobile sources. Source: ARB.

Study Provides Evidence That Low-Level Clouds Act as Positive Feedback to Climate Change

Green Car Congress

Time series of annual mean values of cloud and climate quantities averaged over the NE Pacific. (A) Low-level stratiform clouds—which play an important climatic role because of their net cooling effect on the global climate—appear to dissipate as the ocean warms, thereby enhancing the warming (i.e., A) COADS cloud data. (B)
