The Energy Information Administration (EIA) of the U.S. Department of Energy has just released its Annual Energy Outlook (AEO) 2018, with forecasts for American oil, gas and other forms of energy production through mid-century. As usual, energy journalists and policy makers will probably take the document as gospel.
That's despite the fact that past AEO reports have regularly delivered forecasts that were seriously flawed, as the EIA itself has acknowledged. Further, there are analysts inside and outside the oil and gas industry who crunch the same data the EIA does, but arrive at very different conclusions.

Carbon dioxide emissions from natural gas are projected to exceed emissions from coal by 10 percent this year for the first time since 1972, according to the U.S. Energy Information Administration (EIA).
Last year, natural gas use was 81 percent higher than coal, though their emissions were nearly equal. The EIA also noted that the country's overall carbon intensity has fallen 10 percent since 2005, driven by a decrease in coal use and an uptake of renewables, along with natural gas.
"Another contributing factor to lower carbon intensity is increased consumption of fuels that produce no carbon dioxide, such as nuclear-powered electricity and renewable energy," the EIA report noted.
"As these fuels make up a larger share of U.S. energy consumption, the U.S. average carbon intensity declines. Although use of natural gas and petroleum have increased in recent years, the decline in coal consumption and increase in nonfossil fuel consumption have lowered U.S. total carbon intensity from 60 MMmtCO2/quad Btu in 2005 to 54 MMmtCO2/quad Btu in 2015."

As a certified energy geek, I always look forward to this time of year. On July 11 and July 12, the Energy Information Administration (EIA) holds their annual conference to discuss current energy technology, market and policy issues and presents results from their new Annual Energy Outlook (AEO) 2016 report.
Under EIA's reference case with the federal tax credits and Clean Power Plan, U.S. wind capacity nearly doubles by 2022, reaching 144 gigawatts.
One of the headlines this year is EIA's new projections for renewable energy, which under their reference case is expected to surpass nuclear power by 2020 and coal by 2028 to become the second largest source of U.S. electricity generation after natural gas (see Figure 1 below).
Here are seven key takeaways from the AEO 2016 that explain why EIA is projecting such a large increase in renewable energy this year:
1. Federal Tax Credits and Clean Power Plan Drive Growth in Renewables
EIA's reference case includes the recent five-year extension of the federal production and investment tax credits for wind and solar passed by Congress in December 2015 and implementation of EPA's Clean Power Plan (CPP). While the U.S. Supreme Court put a temporary hold on the rule in February 2016 until the merits of the case are decided, EIA decided to include the CPP in the reference case because the rule has not been overturned.
The federal tax credits, state renewable electricity standards (RESs) and continued cost reductions for wind and solar will drive significant growth in renewables though 2021 (Figure 1). During this time, EIA actually projects natural gas generation to decline slightly as wind and solar are more cost-effective with the tax credits.
After the CPP targets kick in 2022, EIA projects both renewables and natural gas to grow as the two most cost-effective ways (along with a modest increase in energy efficiency) for states to replace coal and comply with the CPP. These results are consistent with recent analyses by the Union of Concerned Scientists (UCS), NREL and the Rhodium Group.

2. Wind and Solar Lead Growth in Renewables
The renewable energy (including wind, solar, geothermal, biomass and hydropower) share of U.S. electricity generation grows from 13 percent in 2015 to 24 percent in 2030 and 27 percent in 2040, with almost all of the growth from wind and solar PV (Figure 2).
This is because continued cost reductions are projected for these technologies beyond the 60-70 percent cost reductions already achieved since 2009. Under EIA's reference case with the federal tax credits and CPP, U.S. wind capacity nearly doubles by 2022, reaching 144 gigawatts, while U.S. solar capacity grows five-fold by 2030, reaching 125 gigawatts. Geothermal increases a significant amount in California and the Southwest, but provides a relatively small share of U.S. electricity generation.
EIA also projects virtually no growth in hydro or biopower. Despite EIA's inaccurate assumption that all biomass feedstocks are carbon neutral, biopower is still not economically competitive with wind, solar and natural gas. The lack of growth in hydro and biomass is consistent with recent analyses by UCS, NREL and Rhodium Group that include the federal tax credit extension and CPP.

3. Renewable Generation Increases in all Regions of the Country by 2030
The biggest increases occur in the West and Plains, which have abundant, low cost wind, solar and geothermal (Figure 3). The Southeast also sees a big increase in solar as costs continue to fall. The Northeast and Mid-Atlantic see a smaller increase in renewables and a bigger increase in natural gas.
The Southeast also sees a modest increase in nuclear generation due to five new reactors currently under construction or operating in Georgia, South Carolina and Tennessee. This growth offsets a modest reduction in nuclear generation in Mid-Atlantic and Northeast states where EIA assumes a small number of existing plants will retire before their current operating licenses expire. (Note that the retirement of Diablo Canyon in California is not included as the announcement was made after EIA completed its modeling). The Midwest/Mid-Atlantic states also see the greatest reduction in coal generation and the largest increase in natural gas.

4. Renewables Generation Varies Under different Clean Power Plan Implementation Scenarios
EIA projects renewable generation to increase the most if states chose rate-based rather than mass-based targets as part of their CPP compliance strategies. Broader regional trading with mass-based targets also results in more renewables, less natural gas and less reduction in coal than the more limited trading assumed in the reference case.
Not surprisingly, in their "extended case" EIA found that continuing to increase the CPP emission reduction targets through 2040 (the current program only goes through 2030) would result in more renewables and natural gas and less coal than the reference case.

5. Increasing Renewable Energy is Affordable
EIA projects that average retail electricity rates would be 3 percent higher between 2025-2030 in the reference case (with the CPP) than in the no CPP case. However, total U.S. electricity expenditures would only be 1.3 percent higher in the CPP case over the same period because EIA assumes a modest increase in energy efficiency investments to comply the CPP.
A recent analysis by UCS found that energy efficiency could make a much larger contribution to state compliance with the CPP that would result in cumulative net savings to consumers of $30.5 billion between 2016 and 2030.
6. Renewables are Competitive Despite Lower Natural Gas Prices
While EIA's natural gas price projection is lower in AEO 2016 than it was in AEO 2015 (Figure 5), large amounts of wind and solar are still competitive due to continued cost reductions and the federal tax credit extension.
EIA projects natural gas prices to double by 2025, due primarily to an increase in LNG exports and greater natural gas use in the electricity and industrial sectors. The competition from renewables helps avoid greater reliance on natural gas that could increase natural gas prices even further.

7. EIA is Finally Using More Realistic Cost Sssumptions for Renewable Energy
UCS has been an outspoken critic of EIA's pessimistic renewable energy projections and assumptions for many years. We have written several blog posts on the topic and provided input directly to EIA on a few of their analyses and as a participant on several EIA modeling working groups. We also use a modified version of EIA's National Energy Modeling System (NEMS) in-house to show how renewables could make a larger contribution to the U.S. electricity mix at a much lower cost when using more realistic assumptions.
One of the main reasons why EIA's projections have fallen short is because they have consistently overestimated the cost of renewable energy technologies like wind and solar. They often lag a few years behind what's happening on the ground. However, this year is different. For AEO 2016, EIA finally lowered their costs for wind and solar to be more in-line with cost data from a large sample of recent projects, as documented by DOE's national labs and the national wind and solar trade associations.
In EIA's defense, their reference case for each AEO only reflects state and federal energy policies that were enacted at the time they do their projections, as discussed extensively in a recent EIA report. With Congress allowing federal renewable energy tax credits to lapse several times before extending them for relatively short periods, and states adopting and increasing renewable electricity standards (RES) many times over the past two decades years, it is somewhat understandable that EIA's projections of renewable energy development have fallen short of reality.
While future EIA conferences and AEOs may highlight different topics, I'll remember 2016 as the year EIA turned the corner to show a bright future for renewables.
Despite the opposition of its chair, the Nuclear Regulatory Commission (NRC) approved the first new construction of a new design of nuclear reactor on Feb. 9 since the Three Mile Island nuclear disaster in 1979. Friends of the Earth stated on Feb. 14 that the decision to give the green light to building two nuclear reactors at Vogtle, Georgia raises fundamental safety and economic concerns.
The NRC ruling, the first such approval in the U.S. in more than 30 years, will saddle Georgians with higher electricity rates and leave American taxpayers on the hook for billions of dollars—all for a dangerous energy source with a long history of construction delays, cost overruns and safety lapses.
“The license may be granted, but these reactors are far from a done deal. As in the past, expect delays and cost overruns, and rest assured that we will challenge the validity of this license in court,” said Damon Moglen, director of Friends of the Earth’s climate and energy project.
In a shocking dissent by NRC Chairman Gregory B. Jazcko against the four other commissioners who approved the decision, Jazcko said that the approved designs did not take the lessons of Fukushima into account. “I cannot support issuing this license as if Fukushima never happened,” Jazcko told his colleagues.
The approval grants a joint construction and operating license to Southern Energy for two new reactors at its existing plant south of Augusta, Ga. It is the first-ever such combined nuclear construction and operation license. The last construction license issued was in 1978 for a reactor at the Shearon Harris site in North Carolina. That reactor took nine years to complete, and three other units planned for the site were cancelled.
Southern Energy claims that the two Vogtle units will be completed within five years at a cost of $14 billion, but the history of such projects indicates that rosy projections of nuclear construction timelines and costs should not be taken at face value. For example, two French-designed nuclear reactors under construction in western Europe are already years behind schedule and billions of dollars over budget. At the Vogtle site, extensive pre-construction has already led to 12 sizeable construction “change order” requests, while long-running site-specific design and fabrication problems have confounded Westinghouse and its lead contractor for more than two years. At the same time, clean renewable energy has been booming in the U.S., growing 38 percent between 2007 and 2010 according to data from the U.S. Energy Information Administration.
Major safety issues with the design of the planned Vogtle reactors remain unresolved, with the NRC failing to address key vulnerabilities. The safety of the reactor design has been challenged over many years. An engineering study commissioned by Friends of the Earth and other groups opposed to the project identified seven key safety areas, including failure risks for the reactor containment, cooling functions and spent fuel pool integrity. The Fukushima-Daiichi accident highlights the dangers of these oversights as it continues 11 months after it began, with leaks of highly radioactive water and rising temperatures in the molten fuel occurring in recent days.
“This is a valentine sent by the Obama administration to the nuclear industry, but it translates into a nightmare for the public, which gets handed increased nuclear hazards and inflated costs for a dangerous, outdated energy source,” said Moglen.
The Vogtle project is entirely dependent on an $8.3 billion pre-emptive bailout promise from the federal government, which comes from the same loan guarantee program as Solyndra’s much ballyhooed $535 million. Vogtle’s loan guarantee is well over 10 times as large as that of the solar company.
“Contrast the enormous risks in economic and public health terms from nuclear projects with the reality of renewable energy and energy efficiency, which are already cost-competitive with nuclear and continue to fall in price. Furthermore, renewable energy promotes rather than endangers public health by cutting global warming pollution, not dirtying the air and, of course, not producing dangerous radioactive waste,” said Moglen.
