7 Reasons to Celebrate 2013's Renewable Energy Achievements
By John Rogers
The last 12 months have brought a lot of change to the world—some good, some less so; some too fast, some too slow. But in the energy space, the essential transition to energy that is cleaner, healthier, lower-cost and more secure is definitely underway in the U.S.

This year, we saw strong signals that we’re moving in the right direction on energy, with renewables like wind and solar (going up), coal (going down), renewables integration (looking good), and energy storage (on its way). Here’s a look at some of the year’s highlights.
1. Wind is getting cheaper all the time.
Utilities keep finding wind energy at Black Friday-worthy prices, as my colleagues have noted (here and here, for example). Long-term wind contracts are now more than 40 percent cheaper than they were just three years ago.
The uncertainty around extension of the Production Tax Credit—which finally came only after the New Year’s champagne was gone—made for a slow start to 2013 overall. But things have picked up, with 7,500 megawatts of wind under development by the third quarter. Now we just need another PTC extension to keep the party going.
2. Solar’s looking better all the time.
Third-quarter figures released last week show that solar continues to thrive, with costs continuing to drop and Q3 being the second-best quarter ever. The U.S. is even on track to potentially install more solar than the world leader, Germany, for the first time in 15 years.
While photovoltaic (PV) tends to attract most of the attention, 2013 has been an important year for progress on concentrating solar power (CSP), too. In October, the first U.S. solar plant with thermal energy storage, Solana, started churning out the kilowatt-hours. And the world’s largest CSP facility, Ivanpah, was getting set to begin commercial operation.
3. Grid folks say more renewables are no prob.
Current levels of renewables are still plenty manageable for regional electricity grid operators used to dealing with the ups and downs of both the supply side (big plants going offline unexpectedly) and the demand side (us not coordinating when turning our fridges and ACs on and off).
Grid operators have continued to find, though, that they can handle much higher levels of variable renewables like wind and solar. A study by grid operator PJM, for example, found that they could get 30 percent of their electricity from wind and solar by 2026, with very little need for extra back-up generation.
4. Storage is moving onto the stage.
Forward-thinking locales are forward thinking about making sure storage can help with that integration of increasing amounts of renewables. In October, California’s public utilities commission moved to jumpstart energy storage in the state, putting in place a storage requirement for the state’s largest utilities.
5. Coal’s economics continue to slide.
Most of the reasons to celebrate are positives, but some are negatives, in a good way. The economics of coal vs. natural gas and wind mean that tens of thousands of megawatts are moving into retirement—including, in just the past few months, plants like Brayton Point, New England’s largest coal plant, and a raft of TVA units.
And the market clearly isn’t done dealing with coal yet. A just-released Union of Concerned Scientists analysis showed a total of an additional 59 to 71 megawatts of coal that is “ripe for retirement”.
6. Power plant carbon standards are progressing.
Creating clear expectations about what we want from the power sector, carbon-wise, is another key part of a successful energy transition. This year brought really important draft standards for new power plants; standards for existing plants are due up next year.
7. People get renewables.
Another “positive negative” for 2013 has been the failure of efforts to weaken clean energy policies across the country. While fossil fuel-funded groups and their allies continued to peddle misinformation to turn people against renewables and efficiency, Truth repeatedly won the day.
The power of the positive was visible recently in the tremendous public pushback on attempts to weaken solar support in Arizona, and in a leading legislative opponent’s failed attempt to undercut Ohio’s clean energy laws.
So, lots of good stuff happening. Our work is far from over—we’re still too hooked on fossil fuels, and suffering the public health impacts; carbon pollution is continuing to climb globally; and opponents of climate and energy progress keep coming up with new and different ways of muddying the decision-making waters. But the clean energy transition is underway.
Where the transition is taking hold, we need to make sure that changes are smooth and just. That communities hosting renewable energy get maximum benefits and minimal downsides. That people affected by coal’s decline (or natural gas’s rise) get support for finding their way to a better future.
Overall, 2013 has given us plenty to celebrate this holiday season. Here’s to a great new year!

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.
