Is Energy 'Dominance' the Right Goal for U.S. Policy?
By Daniel Raimi
In recent weeks, a new energy buzzword has taken flight from Washington, DC, making stops in Alaska, North Dakota, Texas, Utah and more: "American energy dominance." Taking a cue from a 2016 speech by then-candidate Donald Trump, top federal officials including Energy Sec. Rick Perry and Interior Sec. Ryan Zinke have begun to trumpet the notion of energy "dominance."
Although no cabinet official has offered a precise definition, it's a recurring theme in a set of administration events organized around energy policy, including a planned speech by Trump emphasizing exports of coal, natural gas and oil.
So what does this new energy catchphrase mean, and how should we think about it?
For decades, U.S. politicians have trumpeted the notion of energy "independence," focused primarily on the need to eliminate oil imports from OPEC nations and other countries that may not share U.S. interests. But as other energy policy experts have observed, "independence" was never a smart energy goal. Isolating the U.S. from global energy markets is neither in the interest of domestic consumers nor newly resurgent oil and gas producers in the U.S.
For consumers, access to international markets ensures energy supplies at more stable prices. For instance, consider what would happen if a hurricane shut down production and refining along the Gulf Coast, the hub of the U.S. oil and gas industry. Without access to global markets, prices for motor fuels, home heating fuels and other products would be far more volatile.
As for producers, they have argued strongly for opening up, rather than sealing off, access to international energy markets. They've lobbied to lift restrictions on crude oil exports and encouraged exports of natural gas via new pipelines and liquefied natural gas (LNG) terminals.
Spurred by increased oil and gas production as a result of the shale revolution, these policy changes have resulted in dramatic growth in U.S. energy exports. In fact, net energy exports (energy exports minus energy imports) have fallen to their lowest level in decades. The U.S. could even be a net energy exporter by 2020 under one optimistic scenario.

This is a historic change, and administration officials are right to point out that the boom in energy production has benefited local economies, boosted tax revenues and increased U.S. leverage in diplomatic matters with countries like Russia and Iran. It has also raised important environmental and social concerns in impacted communities, such as soil and water contamination from oil and gas wastewater spills, increased traffic accidents and more.
But does does a strengthened oil and gas industry put the U.S. on track to energy dominance? In a word, no.
Pull of global markets
When people use the word "dominant," they might think of the 2017 NBA Golden State Warriors, or Roger Federer in his heyday at Wimbledon.
"Dominance" suggests the U.S. could bend geopolitical adversaries to its will by wielding energy as some type of bargaining chip or weapon. But the buying and selling of oil, gas and other forms of U.S.-produced energy are directed by market forces, not government policy. For example, a large share of recently increased crude oil exports from the U.S. has effectively gone to Venezuela, hardly a close ally. (To be precise, these exports go to the island of Curacao, where a Venezuelan-owned refinery blends U.S. light oil with heavier Venezuelan crudes.)
Indeed, U.S. policymakers routinely object when other nations (such as Iran, Russia or Saudi Arabia) make decisions about buying or selling energy with geopolitical goals in mind. What's more, manipulating energy exports to punish or reward other nations would almost certainly lead to retaliation, erecting new trade barriers that would ultimately harm the domestic and global economy.

And even if it were desirable, "dominance" of global energy markets in today's world is simply unrealistic. There is no Roger Federer of energy.
Consider the Organization of Petroleum Exporting Countries (OPEC), maybe the closest thing to the Golden State Warriors of the energy world, which has struggled mightily in recent years to exert some control over consistently low oil prices. U.S. oil and natural gas producers, while reemergent as major players, do not have OPEC's market power, let alone that of John D. Rockefeller in the late 1800s and early 1900s or the Texas Railroad Commission from the 1930s through the 1960s (see the excellent new book "Crude Volatility" for more on this).
And why is it unrealistic to expect U.S. producers to exert this type of power? The answer lies in the enormous scale of the global energy system, which is many times larger than in the heyday of Rockefeller or other effective market managers.
A better objective
When viewed on this global scale, the resurgence of U.S. energy production looks more far more modest. The scale of current and projected global energy demand is so vast, changes in trends of U.S. energy production hardly make a dent. As a share of global energy demand, U.S. production has actually declined from 24 percent in 1980 to about 15 percent today, and is projected to decline further—even under a scenario where domestic oil and gas production grows more rapidly than expected—to 13 percent by 2040.
Even with surging oil and gas production, the U.S. still only supplies a small portion of global demand, which limits its geopolitical influenceEnergy Information Administration
To craft smart energy policies, decision-makers need to clearly identify their objectives, then work toward meeting them. These objectives should focus on enabling widespread access to reliable, affordable and sustainable energy sources.
Like its forerunner, energy "independence," the notion of American energy "dominance" is unrealistic, given the outsize role global markets play compared to U.S. policy, and it unwisely distracts from the goals that should be shaping U.S. energy policy.

If weather is your mood, climate is your personality. That's an analogy some scientists use to help explain the difference between two words people often get mixed up.
Size Matters<p>Climates are a bit like woven tapestries. The big picture is important, no question. But so are all the seemingly minor details found inside the larger whole.</p><p><a href="https://research-information.bris.ac.uk/en/persons/tommaso-jucker" target="_blank">Tommaso Jucker</a> is an environmental scientist at the University of Bristol. In an email, Jucker says he'd define the term microclimate as "the suite of climatic conditions (temperature, rainfall, humidity, solar radiation) measured in localized areas, typically near the ground and at spatial scales that are directly relevant to ecological processes."</p><p>We'll talk about that last bit in a minute. But first, there's another criteria to discuss. According to some researchers, a microclimate — by definition — must differ from the larger area that surrounds it.</p><p><a href="https://www.cfc.umt.edu/research/paleoecologylab/publications/Davis_et_al_2019_Ecography.pdf" target="_blank">Forests</a> provide us with some great examples. "The climate near the ground in a tropical rainforest is dramatically different from the climate in the canopy 50 meters [164 feet] above," says University of Montana ecologist <a href="https://www.cfc.umt.edu/personnel/details.php?ID=1110" target="_blank">Solomon Dobrowski</a> in an email. "This vertical gradient among other factors allows for the staggering biodiversity we see in the tropics."</p><p>Likewise, scientists observed that a 2015 partial <a href="https://animals.howstuffworks.com/insects/bees-stopped-buzzing-during-2017-solar-eclipse.htm" target="_blank">solar eclipse</a> caused the air temperature of an Eastern European meadow to <a href="https://rmets.onlinelibrary.wiley.com/doi/full/10.1002/wea.2802" target="_blank">change more dramatically</a> than it did in a nearby forest. That's because trees provide not only shade, but their leaves also reflect solar radiation. At the same time, forests tend to reduce wind speeds.</p><p>All those factors add up. A 2019 review of 98 wooded places — spread out across five continents — found that forests are 7.2 degrees Fahrenheit (4 degrees Celsius) <a href="https://natureecoevocommunity.nature.com/posts/47363-forests-protect-animals-and-plants-against-warming" target="_blank">cooler on average</a> than the areas outside them.</p><p>Now if you hate the cold, don't worry; there's a cozy exception to the rule. According to that same study, forests are usually 1.8 degrees Fahrenheit (1 degree Celsius) warmer than the external environment during the wintertime. Pretty cool.</p>
A Bug's Life<p>When does a microclimate stop being, well, micro? In other words, is there a maximum size we should be aware of when discussing them?</p><p>Depends on who you ask. "In terms of horizontal scale, some have defined 'microclimate' as anything that is less than 100 meters [328 feet] in range," Jucker says. "I'm personally less prescriptive about this."</p><p>Instead, he says the "scale at which we want to measure [a particular] microclimate" ought to be "dictated" by the questions we're trying to answer.</p><p>"If I want to know how temperature affects the photosynthesis of a leaf, I should be measuring temperature at centimeter scale," Jucker explains. "If I want to know if and how temperature affects the habitat preference of a large, mobile mammal, it's probably more relevant to capture temperature variation across [tens to hundreds] of meters."</p><p>For instance, solitary plants have the power to generate itty-bitty microclimates. Just ask <a href="https://www.colorado.edu/geography/peter-blanken-0" target="_blank">Peter Blanken</a>, a geography professor at the University of Colorado, Boulder and the co-author of the 2016 book, "<a href="https://amzn.to/2XN6FT8" target="_blank">Microclimate and Local Climate</a>."</p>
The urban heat island effect is a good example of how microclimates work. NOAA
Microclimates on a Grand Scale<p>It's no secret that our planet is going through some rough times at the macro level. The global temperature is <a href="https://climate.nasa.gov/vital-signs/global-temperature/" target="_blank">climbing</a>; nine out of the <a href="https://www.noaa.gov/news/2019-was-2nd-hottest-year-on-record-for-earth-say-noaa-nasa" target="_blank">10 hottest years on record</a> have occurred since 2005. And by one recent estimate, roughly 1 million species around the world are <a href="https://ipbes.net/sites/default/files/2020-02/ipbes_global_assessment_report_summary_for_policymakers_en.pdf" target="_blank">facing extinction</a> due to human activities.</p><p>"One of the big questions that ecologists and environmental scientists are trying to answer right now is how will individual species and whole ecosystems respond to rapid climate change and habitat loss," says Jucker. "...To me, [microclimates are] a key component of this research — if we don't measure and understand climate at the appropriate scale, then predicting how things will change in the future becomes a lot harder."</p><p>Developers have long understood the impact small-scale climates have on our daily lives. <a href="https://science.howstuffworks.com/environmental/green-science/urban-heat-island.htm#pt0" target="_blank">Urban heat islands</a> are cities that have higher temperatures than neighboring rural areas.</p><p>Plants release vapors that can moderate local climates. But in cities, natural greenery is often scarce. To make matters worse, plenty of our roads and buildings have a bad habit of absorbing or re-emitting heat from the sun. <a href="https://www.google.com/books/edition/Microclimate_and_Local_Climate/LHUZDAAAQBAJ?hl=en&gbpv=1&bsq=urban%20heat%20island" target="_blank">Vehicle emissions</a> don't exactly help the situation.</p><p>Still, it's not like Boston or Beijing are thermal monoliths. Sometimes, the documented temperatures <a href="https://e360.yale.edu/features/can-we-turn-down-the-temperature-on-urban-heat-islands" target="_blank">within a single city</a> vary by 15 to 20 degrees Fahrenheit (8.3 to 11.1 degrees Celsius).</p><p>That's where metro parks and city trees come in. They have nice cooling effects on nearby neighborhoods. "Several cities around the world have developed programs to increase urban green spaces," says Blanken. "Tree planting programs and green roof programs, have been shown to lower surface temperatures, decrease air pollution and decrease surface water runoff (urban flash-flooding) in urban areas."</p>

If asked to recall a hurricane, odds are you'd immediately invoke memorable names like Sandy, Katrina or Harvey. You'd probably even remember something specific about the impact of the storm. But if asked to recall a heat wave, a vague recollection that it was hot during your last summer vacation may be about as specific as you can get.

One of the challenges of renewable power is how to store clean energy from the sun, wind and geothermal sources. Now, a new study and advances in nanotechnology have found a method that may relieve the burden on supercapacitor storage. This method turns bricks into batteries, meaning that buildings themselves may one day be used to store and generate power, Science Times reported.
Bricks are a preferred building tool for their durability and resilience against heat and frost since they do not shrink, expand or warp in a way that compromises infrastructure. They are also reusable. What was unknown, until now, is that they can be altered to store electrical energy, according to a new study published in Nature Communications.
The scientists behind the study figured out a way to modify bricks in order to use their iconic red hue, which comes from hematite, an iron oxide, to store enough electricity to power devices, Gizmodo reported. To do that, the researchers filled bricks' pores with a nanofiber made from a conducting plastic that can store an electrical charge.
The first bricks they modified stored enough of a charge to power a small light. They can be charged in just 13 minutes and hold 10,000 charges, but the challenge is getting them to hold a much larger charge, making the technology a distant proposition.
If the capacity can be increased, researchers believe bricks can be used as a cheap alternative to lithium ion batteries — the same batteries used in laptops, phones and tablets.
The first power bricks are only one percent of a lithium-ion battery, but storage capacity can be increased tenfold by adding materials like metal oxides, Julio D'Arcy, a researcher at Washington University in St. Louis, Missouri, who contributed to the paper and was part of the research team, told The Guardian. But only when the storage capacity is scaled up would bricks become commercially viable.
"A solar cell on the roof of your house has to store electricity somewhere and typically we use batteries," D'Arcy told The Guardian. "What we have done is provide a new 'food-for-thought' option, but we're not there yet.
"If [that can happen], this technology is way cheaper than lithium ion batteries," D'Arcy added. "It would be a different world and you would not hear the words 'lithium ion battery' again."
One of the concerns about a warming planet is the feedback loop that will emerge. That is, as the planet warms, it will melt permafrost, which will release trapped carbon and lead to more warming and more melting. Now, a new study has shown that the feedback loop won't only happen in the nether regions of the north and south, but in the tropics as well, according to a new paper in Nature.
