Low-Carbon Electricity Pathways for the U.S. and the South

Monday, August 3rd, 2015
Figure 1. The Proposed Emissions Rate Reduction Targets

GEORGIA INSTITUTE OF TECHNOLOGY SCHOOL OF PUBLIC POLICY
Power plants are one of the largest sources of carbon pollution in the U.S., accounting for nearly 39% of annual CO2 emissions from the combustion of fossil fuels (EIA, 2014, Table A.18). On June 2, 2014, the U.S. Environmental Protection Agency (EPA) proposed state-specific limits on CO2 emissions from existing fossil fuel-fired electric generating units (EGUs) as part of its Clean Power Plan (CPP).

UNITED STATES CHAMBER OF COMMERCE
As Congress gears up to debate reauthorization of surface transportation programs, this report is intended to call attention to a significant emerging threat to addressing the aforementioned transportation challenges: the Environmental Protection Agency’s (EPA) forthcoming ozone national ambient air quality standards (NAAQS). This report analyzes the impact of these regulations on transportation projects, with a focus on the Washington, D.C. metropolitan area.

Benchmarking Air Emissions

Monday, July 20th, 2015
TABLE 1 100 Largest Electric Power Producers in the U.S. (in order of 2013 electric generation)

CERES
This report examines and compares the stack air pollutant emissions of the 100 largest power producers in the United States based on their 2013 generation, plant ownership, and emissions data. Table 1 lists the 100 largest power producers featured in this report ranked by their total electricity generation from fossil fuel, nuclear, and renewable energy facilities. These producers include public and private entities1 (collectively referred to as “companies” or “producers” in this report) that own roughly 2,800 power plants and account for 85 percent of reported electric generation and 87 percent of the industry’s reported emissions.

Clean Power Plan: Markets Drive Innovation

Figure 1. Lead Permits Traded as Percent of All Lead Emissions, 1983-1987

ADVANCED ENERGY ECONOMY INSTITUTE (AEE INSTITUTE)
On June 2, 2014, the Environmental Protection Agency (EPA) proposed the Clean Power Plan (CPP) to implement section 111(d) of the Clean Air Act (CAA). While the proposed rule does not mandate a market-based approach to compliance, ample evidence from previous CAA rules suggests that market-based mechanisms are likely to develop under the CPP, and that these mechanisms will spark an industry response that will make available a wide array of cost-effective compliance options.

2015 U.S. Clean Tech Leadership Index

Thursday, July 9th, 2015
2015 TOP 10 STATES (INCLUDING HISTORICAL RANKINGS)

CLEAN EDGE
The United States has seen a significant shift in its energy landscape since Clean Edge began publishing its clean-tech leadership index five years ago. The transition to a clean tech and energy efficiency-based economy, based on the many indicators we track, is well underway. Solar and wind power, along with natural gas and energy efficiency, are now the mainstream choices for meeting the nation’s electricity needs; coal-fired and nuclear power, the dominant choices of the 20th century, have become the marginalized “alternatives.”

Transitioning to Low-Carbon Trucks

Figure ES-1. Required ZEV sales share to hit 80-in-50 target with no biofuels v. scenario with 60% biofuels blends by2050

NATIONAL CENTER FOR SUSTAINABLE TRANSPORTATION
UC DAVIS INSTITUTE OF TRANSPORTATION STUDIES
The United States and California have both made commitments to an 80% reduction in energy-related greenhouse gases (GHGs) from 1990 levels by 2050 in order to help stabilize atmospheric concentrations of greenhouse gases. These commitments do not specifically target transportation or an individual transport mode.

This white paper reviews previous studies and provides a new investigation into the feasibility of achieving an 80% reduction in CO2-equivalent (CO2e) GHG emissions in the United States and California from trucks in the 2050 time frame (“80-in-50”). We assess the technological and economic potential of achieving deep market penetrations of low-carbon vehicles and fuels, including vehicles operating on electricity, hydrogen, and biofuels.

Renewable Energy and Jobs: Annual Review 2015

Wednesday, May 27th, 2015
Figure 1. Renewable energy employment by technology

INTERNATIONAL RENEWABLE ENERGY AGENCY (IRENA)
IRENA estimates that renewable energy employed 7.7 million people, directly or indirectly, around the world in 2014(excluding large hydropower). This is an 18% increase from the number reported last year. In addition, IRENA conducted the first-ever global estimate of large hydropower employment, showing approximately 1.5 million direct jobs in the sector.

Tapping Iowa’s Wind Resources to Reduce CO2 Emissions

Thursday, May 7th, 2015
Of particular interest is the corollation especially observable in the 2010 – 2012 years, between the CO2

IOWA WIND ENERGY ASSOCIATION
In a conservative scenario it is estimated that Iowa wind could easily contribute a reduction of 15 million metric tons of carbon dioxide annually to the region outside of Iowa, and in a more optimistic but still moderate scenario Iowa’s contribution could easily be over 36 million metric tons annually.
