7 Reasons Renewable Energy Will Soon Surpass Coal and Nuclear Power
By Steve Clemmer
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.
Figure 4. Cumulative difference in generation in the CPP vs. the no CPP case. Renewables = green, natural gas =blue, and coal = black.EIA, Annual Energy Outlook 2016.
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.

1. Stay Informed<p>A first order of business in pet evacuation planning is to understand and be ready for the possible threats in your area. Visit <a href="https://www.ready.gov/be-informed" target="_blank">Ready.gov</a> to learn more about preparing for potential disasters such as floods, hurricanes, and wildfires. Then pay attention to related updates by tuning <a href="http://www.weather.gov/nwr/" target="_blank">NOAA Weather Radio</a> to your local emergency station or using the <a href="https://www.fema.gov/mobile-app" target="_blank">FEMA app</a> to get National Weather Service alerts.</p>
2. Ensure Your Pet is Easily Identifiable<p><span>Household pets, including indoor cats, should wear collars with ID tags that have your mobile phone number. </span><a href="https://www.avma.org/microchipping-animals-faq" target="_blank" rel="noopener noreferrer">Microchipping</a><span> your pets will also improve your chances of reunion should you become separated. Be sure to add an emergency contact for friends or relatives outside your immediate area.</span></p><p>Additionally, use <a href="https://secure.aspca.org/take-action/order-your-pet-safety-pack" target="_blank" rel="noopener noreferrer">'animals inside' door/window stickers</a> to show rescue workers how many pets live there. (If you evacuate with your pets, quickly write "Evacuated" on the sticker so first responders don't waste time searching for them.)</p>
3. Make a Pet Evacuation Plan<p> "No family disaster plan is complete without including your pets and all of your animals," says veterinarian Heather Case in <a href="https://www.youtube.com/watch?v=Q9NRJkFKAm4" target="_blank">a video</a> produced by the American Veterinary Medical Association.</p><p>It's important to determine where to take your pet in the event of an emergency.</p><p>Red Cross shelters and many other emergency shelters allow only service animals. Ask your vet, local animal shelters, and emergency management officials for information on local and regional animal sheltering options.</p><p>For those with access to the rare shelter that allows pets, CDC offers <a href="https://www.cdc.gov/healthypets/emergencies/pets-in-evacuation-centers.html" target="_blank">tips on what to expect</a> there, including potential health risks and hygiene best practices.</p><p>Beyond that, talk with family or friends outside the evacuation area about potentially hosting you and/or your pet if you're comfortable doing so. Search for pet-friendly hotel or boarding options along key evacuation routes.</p><p>If you have exotic pets or a mix of large and small animals, you may need to identify multiple locations to shelter them.</p><p>For other household pets like hamsters, snakes, and fish, the SPCA recommends that if they normally live in a cage, they should be transported in that cage. If the enclosure is too big to transport, however, transfer them to a smaller container temporarily. (More on that <a href="https://www.spcai.org/take-action/emergency-preparedness/evacuation-how-to-be-pet-prepared" target="_blank" rel="noopener noreferrer">here</a>.)</p><p>For any pet, a key step is to establish who in your household will be the point person for gathering up pets and bringing their supplies. Keep in mind that you may not be home when disaster strikes, so come up with a Plan B. For example, you might form a buddy system with neighbors with pets, or coordinate with a trusted pet sitter.</p>
4. Prepare a Pet Evacuation Kit<p>Like the emergency preparedness kit you'd prepare for humans, assemble basic survival items for your pets in a sturdy, easy-to-grab container. Items should include:</p><ul><li>Water, food, and medicine to last a week or two;</li><li>Water, food bowls, and a can opener if packing wet food;</li><li>Litter supplies for cats (a shoebox lined with a plastic bag and litter may work);</li><li>Leashes, harnesses, or vehicle restraints if applicable;</li><li>A <a href="https://www.avma.org/resources/pet-owners/emergencycare/pet-first-aid-supplies-checklist" target="_blank">pet first aid kit</a>;</li><li>A sturdy carrier or crate for each cat or dog. In addition to easing transport, these may serve as your pet's most familiar or safe space in an unfamiliar environment;</li><li>A favorite toy and/or blanket;</li><li>If your pet is prone to anxiety or stress, the American Kennel Club suggests adding <a href="https://www.akc.org/expert-advice/home-living/create-emergency-evacuation-plan-dog/" target="_blank" rel="noopener noreferrer">stress-relieving items</a> like an anxiety vest or calming sprays.</li></ul><p>In the not-unlikely event that you and your pet have to shelter in different places, your kit should also include:</p><ul><li>Detailed information including contact information for you, your vet, and other emergency contacts;</li><li>A list with phone numbers and addresses of potential destinations, including pet-friendly hotels and emergency boarding facilities near your planned evacuation routes, plus friends or relatives in other areas who might be willing to host you or your pet;</li><li>Medical information including vaccine records and a current rabies vaccination tag;</li><li>Feeding notes including portions and sizes in case you need to leave your pet in someone else's care;</li><li>A photo of you and your pet for identification purposes.</li></ul>
5. Be Ready to Evacuate at Any Time<p>It's always wise to be prepared, but stay especially vigilant in high-risk periods during fire or hurricane season. Practice evacuating at different times of day. Make sure your grab-and-go kit is up to date and in a convenient location, and keep leashes and carriers by the exit door. You might even stow a thick pillowcase under your bed for middle-of-the-night, dash-out emergencies when you don't have time to coax an anxious pet into a carrier. If forecasters warn of potential wildfire, a hurricane, or other dangerous conditions, bring outdoor pets inside so you can keep a close eye on them.</p><p>As with any emergency, the key is to be prepared. As the American Kennel Club points out, "If you panic, it will agitate your dog. Therefore, <a href="https://www.akc.org/expert-advice/home-living/create-emergency-evacuation-plan-dog/" target="_blank" rel="noopener noreferrer">pet disaster preparedness</a> will not only reduce your anxiety but will help reduce your pet's anxiety too."</p>
Evacuating Horses and Other Farm Animals<p>The same basic principles apply for evacuating horses and most other livestock. Provide each with some form of identification. Ensure that adequate food, water, and medicine are available. And develop a clear plan on where to go and how to get there.</p><p>Sheltering and transporting farm animals requires careful coordination, from identifying potential shelter space at fairgrounds, racetracks, or pastures, to ensuring enough space is available in vehicles and trailers – not to mention handlers and drivers on hand to support the effort.</p><p>For most farm animals, the Red Cross advises that you consider precautionary evacuation when a threat seems imminent but evacuation orders haven't yet been announced. The American Veterinary Medical Association has <a href="https://www.avma.org/resources/pet-owners/emergencycare/large-animals-and-livestock-disasters" target="_blank">more information</a>.</p>
Bottom Line: If You Need to Evacuate, So Do Your Pets<p>As the Humane Society warns, pets left behind in a disaster can easily be injured, lost, or killed. Plan ahead to make sure you can safely evacuate your entire household – furry members included.</p>
