The energy portfolio is changing for both the United States and Australia. Both countries are rich in fossil fuel reserves and both depend on burning them as a large source of energy. Both export coal and natural gas. Both are moving to more renewable supply of energy, although with different drivers and different degrees of government leadership. The United States has a sizeable nuclear component to its energy generation portfolio, but Australia does not due to a legal prohibition. How each country meets its goals of reduced carbon emissions (official or unofficial goals) is not clear at this time.

Abstract Refinements in the spatial and temporal resolution of North American fossil-fuel carbon dioxide (CO2) emissions provide additional information about anthropogenic aspects of the carbon cycle. In North America, the seasonal and spatial patterns are a distinctive component to characterizing anthropogenic carbon emissions. The pattern of fossil-fuel-based CO2 emissions on a monthly scale has greater temporal and spatial variability than the flux aggregated to the national annual level. For some areas, monthly emissions can vary by as much as 85% for some fuels when compared with monthly estimates based on a uniform temporal and spatial distribution. The United States accounts for the majority of North American fossil carbon emissions, and the amplitude of the seasonal flux in emissions in the United States is greater than the total mean monthly emissions in both Canada and Mexico. Nevertheless, Canada and Mexico have distinctive seasonal patterns as well. For the continent, emissions were aggregated on a 5° × 10° latitude–longitude grid. The monthly pattern of emissions varies on both a north–south and east–west gradient and evolves through the time period analyzed (1990–2007). For many areas in North America, the magnitude of the month-to-month variation is larger than the total annual emissions from land use change, making the characterization of emissions patterns essential to understanding humanity’s influence on the carbon cycle.

Fossil Fuel Subsidies

This paper estimates the financial benefits accruing to fossil fuel producers (i.e., the producer incidence) that arise because of implicit fossil fuel subsidies in the United States. The analysis takes account of coal, natural gas, gasoline, and diesel, along with the implicit subsidies due to externalized environmental damages, public health effects, and transportation-related costs. The direct benefit to fossil fuel producers across all four fuels is estimated at $62 billion per year, a sum calculated due to the higher price that suppliers receive because of inefficient pricing compared to the counterfactual scenario where environmental and public health externalities are internalized. A significant portion of these benefits accrue to relatively few companies, and specific estimates are provided for companies with the largest production. The financial benefit because of unpriced costs borne by society is comparable to 18% of net income from continuing domestic operations for the median natural gas and oil producer in 2017–2018, and it exceeds net income for the majority of coal producers. The results clarify what the domestic fossil fuel industry has at stake financially when it comes to policies that seek to address climate change, adverse health effects from local pollution, and inefficient transportation.

Over Time

Energy Independence as well as concern for carbon emissions are policy topics that have been frequently discussed on the public stage. This paper analyzes the possibility of creating an energy portfolio that will achieve energy independence while reducing carbon emissions and how that portfolio is likely to change over time. Domestic oil, hydrogen fuels, domestic natural gas, hydropower, wind power, solar power, and nuclear power are the fuels discussed to make up the energy portfolio that will eliminate the United States dependence on foreign oil while reducing the carbon emissions generated during the production of energy.
