How California Will Use Renewables to Replace Massive Nuclear Plant
By Sierra Martinez
California took another major and symbolic step this month with its decision to rely significantly on energy efficiency and other clean energy resources to help replace electricity once generated by the San Onofre Nuclear Generation Station (SONGS) serving San Diego and the greater Los Angeles area.
The California Public Utilities Commission (CPUC) made official its strategy to address the loss of the huge nuclear plant, which had been offline since January 2012 and was officially retired last year. Fortunately, it closely resembles its proposal released last month.
The final plan uses efficiency and other “preferred resources”—those resources with lower environmental impacts—like demand response (ways customers can consume less energy at key times during the day) and renewable energy such as wind and solar, as well as some upgrades to the electric system, to replace the vast majority of the lost SONGS generation. Instead of turning directly to dirty gas-fired power to replace SONGS, this decision fills the gap left by SONGS with at least two-thirds of clean energy resources, and up to 100 percent clean energy. That means that dirty gas-fired power is limited to contributing, at most, one-third of the replacement energy and at best, zero.
The groundbreaking step puts California on a better course for the long term, avoiding a significant number of fossil-fueled power plants, and those power plants' emissions that Californians are all too familiar with. As the state gears up for the summer strain on the grid this year, two of California’s largest metropolitan areas—Los Angeles and San Diego—begin to dread their often daily dose of smog and its related quality-of-life and even medical issues.
Positive Steps Forward
We applaud the commission for moving in the right direction and, especially for its significant reliance on the contribution of “preferred resources”—resources that are critical to the health and well-being of Californians.
In addition, it’s notable that the commission authorized no additional mandatory gas-fired power sources (which create emissions) because previously, the commission did enact mandatory gas requirements in its 2013 decision. This frees the utilities to appreciably, if not entirely, rely on clean energy resources to replace SONGS.
California has embraced efficiency—getting the same or more work from less electricity—as the cleanest, simplest and most cost-effective energy resource. Not only does efficiency lead to lower utility bills, it reduces the amount of electricity that must be generated from dirty energy that pollutes our air and harms our health.
The fear had been that the replacement of SONGS, a mammoth 2,200-megawatt (MW) power plant (equivalent to about four regular large-sized power plants) around which much of the California transmission grid was built, and which left an over 2,500 MW hole in the grid (due in part to its electrical location and characteristics), would be met with the least creative response—the excessive use of more fossil-fueled power plants.
In June 2012, for example, a retired 50-year-old gas-fired generator at Huntington Beach was brought online to help address the loss of SONGS, but not so much for energy but rather to maintain voltage levels—a complex demand-and-supply balancing act. Fortunately, with this long term decision, the state is definitively not going to make excessive reliance on gas-fired power plants its long term solution.
The decision, which affirms that clean energy is the pillar of replacing California’s retired nuclear plant, the state will:
- Rely on the supply of energy from what amounts to two medium-sized fossil-fuel power plants (600 MW of power) from “preferred sources”—those that have lower environmental impacts and lower public health costs—like efficiency, reducing energy consumption at peak times, wind, solar, and energy storage.
- Use 400 to 900 MW of power from new resources, meaning any type of energy resource as needed. This historically has meant gas-fired power generation because many preferred resources were competing on a non-level playing field, but new language requests more fairness in competition for cleaner sources such as efficiency, demand response, solar and wind.
These sources will account for between 1,000 and 1,500 MW of power to replace the more than 2,500-MW hole in the grid left by SONGS. Fortunately, the remainder is made up by additional solutions that are not fossil-fueled power plants, such as reducing the demand through energy efficiency and making improvements to transmission networks. This diverse portfolio of resources will meet the extensive voltage support, energy, and power needs that were originally provided by SONGS.
As a result, this move is good news for Californians and the air we breathe.
Room For Improvement
While the plan is well-balanced, NRDC is concerned that the plan failed to explicitly rely on all reasonably-expected-to-occur energy efficiency. As NRDC demonstrated in the proceeding, the model results that used the best resource estimates available showed there was no clear need to authorize any additional gas-fired generation at this time (beyond the 1,500 MW of gas-fired generation already authorized in 2013) to replace SONGS. These estimates explicitly rely on a conservative 733 MW of savings from building efficiency standards, appliance efficiency standards, and utility efficiency programs. We know the efficiency estimates should have been even higher – because the 733 MW estimate didn’t account for the recently-adopted federal appliance efficiency standards, like efficiency standards for microwaves and commercial refrigerators.
The plan also underestimated other preferred resources and transmission solutions, discounting those resources by up to 90 percent. We called for improving the accounting of these preferred resources because an assumption that their contributions are only worth 10 percent was not backed by the record.
While it has its shortcomings, the replacement strategy significantly avoids the construction of many fossil-fueled power plants and is a critical step forward for California’s clean energy future. For Californians within the greater Los Angeles region and in San Diego region, their health and environment will be directly affected by this decision. And for the entire state of California, this decision will have a major impact on future long term energy planning because it demonstrates that we can replace an enormous nuclear power plant with largely clean energy and transmission solutions.

Maybe you're trying to eat healthier these days, aiming to get enough of the good stuff and limit the less-good stuff. You're paying attention to things like fiber and fat and vitamins … and anti-nutrients?
What Are Anti-Nutrients?<p><a href="https://www.hsph.harvard.edu/nutritionsource/anti-nutrients/" target="_blank" rel="noopener noreferrer">Anti-nutrients are substances</a> that naturally occur in plant and animal foods.</p><p>The name comes from how they function in your body once you eat them. They <a href="https://www.sciencedirect.com/topics/food-science/antinutrients" target="_blank">block or interfere with how your body</a> <a href="https://doi.org/10.1631/jzus.B0710640" target="_blank" rel="noopener noreferrer">absorbs other nutrients</a> out of your gut and into your bloodstream so you can then use them. Thus, anti-nutrients may decrease the amount of nutrients you actually get from your food. They most commonly interfere with the absorption of <a href="https://doi.org/10.1016/j.jand.2016.09.025" target="_blank" rel="noopener noreferrer">calcium, iron, potassium, magnesium and zinc</a>.</p><p>Plants evolved these <a href="https://www.todaysdietitian.com/newarchives/070111p54.shtml" target="_blank" rel="noopener noreferrer">compounds as a defensive mechanism</a> against insects, parasites, bacteria and fungi. For example, some anti-nutrients can cause a food to taste bitter; animals won't want to eat it, leaving the seed, for instance, to provide nourishment for future seedlings. Some anti-nutrients block the digestion of seeds that are eaten. The seeds disperse when they come out the other end in the animal's fecal matter and can go on to grow new plants. Both of these survival tactics help the plant species grow and spread.</p><p><span></span>In terms of foods that people eat, you'll most commonly find anti-nutrients naturally occurring in whole grains and legumes.</p>
Time for an Image Makeover as Health Enhancers<p>Despite sounding scary, studies show that anti-nutrients are not of concern unless consumed in <a href="https://doi.org/10.1016/j.jcs.2014.01.010" target="_blank">ultra, unrealistically high amounts</a> – and they have numerous health benefits.</p><p>Anti-nutrients are currently undergoing a change in image very similar to the one dietary fiber experienced. At one point, scientists thought dietary fiber was bad for people. Since fiber could bind to nutrients and pull them out of the digestive tract in poop, it seemed like something to avoid. To address this perceived issue, grain processing in the late 1800s removed fiber from foods.</p><p>But now scientists know that <a href="https://doi.org/10.1111/j.1753-4887.2009.00189.x" target="_blank">dietary fiber is incredibly important</a> and encourage its consumption. Eating plenty of fiber lowers the risks of obesity, high blood pressure, heart disease, stroke, diabetes and some gastrointestinal diseases.</p><p>In the same way, rather than something to avoid, many anti-nutrients are now considered health-promoting nutraceuticals and functional foods due to their numerous benefits. Here's an introduction to some of the most frequently eaten anti-nutrients that come with benefits:</p><ul><li><a href="https://doi.org/10.1089/109662004322984734" target="_blank" rel="noopener noreferrer">Saponins, common in legumes</a>, can boost the immune system, reduce risk of cancer, lower cholesterol, lower blood sugar response to foods, result in fewer cavities, reduce risk of kidney stones and combat blood clotting seen in heart attacks and strokes.</li><li><a href="https://doi.org/10.1016/j.jcs.2014.01.010" target="_blank" rel="noopener noreferrer">Lectins, found in cereal grains and legumes</a>, are associated with reduced risk of cardiovascular disease, diabetes, some cancers and becoming overweight or obese.</li><li><a href="https://doi.org/10.1080/10408699891274273" target="_blank" rel="noopener noreferrer">Tannins, commonly found in teas, coffees and processed meats and cheeses</a>, are antioxidants that can inhibit growth of bacteria, viruses, fungi and yeast and may decrease cholesterol levels and blood pressure.</li><li><a href="https://doi.org/10.1631/jzus.B0710640" target="_blank" rel="noopener noreferrer">Phytates, found in wheat, barley, rice and corn</a>, are associated with increased immune function and cancer cell death, as well as reduced cancer cell growth and spread. They also have antioxidant properties and can reduce inflammation.</li><li>Finally, <a href="https://doi.org/10.1024/0300-98184.108.40.206" target="_blank" rel="noopener noreferrer">glucosinates, found in brassica vegetables</a> like cauliflower, inhibit tumor cell growth.</li></ul><p>Oxalates are one of the few anti-nutrients with mostly negative impacts on the body. They are <a href="https://www.uofmhealth.org/health-library/aa166321" target="_blank" rel="noopener noreferrer">found in lots of common foods</a>, including legumes, beets, berries, cranberries, oranges, chocolate, tofu, wheat bran, soda, coffee, tea, beer, dark green vegetables and sweet potatoes. The negative impacts of oxalates include binding to calcium in the digestive tract and removing it from the body in bowel movements. Oxalates can also <a href="https://www.uofmhealth.org/health-library/aa166321" target="_blank" rel="noopener noreferrer">increase the risk of kidney stones</a> in some people.</p>
Fitting Anti-Nutrients Into a Healthy Diet<p>Overall, comparing the benefits to the drawbacks, anti-nutrient pros actually outweigh the cons. The healthy foods that contain them – mainly fruits, vegetables, whole grains and legumes – should be encouraged not avoided.</p><p>Anti-nutrients become a concern only if these foods are consumed in ultra-high amounts, <a href="https://www.ars.usda.gov/research/project/?accnNo=426312" target="_blank" rel="noopener noreferrer">which is very unlikely</a> for most adults and children in the U.S. Additionally, a large proportion of anti-nutrients are removed or lost from foods people eat <a href="https://www.hsph.harvard.edu/nutritionsource/anti-nutrients/" target="_blank" rel="noopener noreferrer">as they're processed and cooked</a>, especially if soaking, blanching, boiling or other high-heat processes are involved.</p><p>Vegetarians and vegans may be at higher risk of negative effects from anti-nutrients because their diet relies heavily on fruits, vegetables, whole grains and legumes. But these <a href="https://doi.org/10.1016/j.jand.2016.09.025" target="_blank" rel="noopener noreferrer">plant-based diets are still among the healthiest</a> and are associated with reduced risk of cardiovascular disease, obesity, diabetes and numerous types of cancers.</p><p>Vegetarians and vegans can take a few steps to help counteract anti-nutrients' effects on their absorption of particular nutrients:</p><ul><li>Pair high iron <a href="https://doi.org/10.1093/jn/130.5.1378S" target="_blank" rel="noopener noreferrer">and zinc</a> <a href="https://doi.org/10.1016/bs.afnr.2014.11.003" target="_blank" rel="noopener noreferrer">foods with</a> <a href="https://doi.org/10.1093/ajcn/59.5.1233S" target="_blank" rel="noopener noreferrer">foods high in vitamin C</a> (examples: meatballs with tomato sauce, tomato-based chili with beans).</li><li><a href="https://www.jblearning.com/catalog/productdetails/9780763779764?jblsearch" target="_blank" rel="noopener noreferrer">Soak legumes before cooking</a>.</li><li><a href="https://doi.org/10.1093/ajcn/70.3.543s" target="_blank" rel="noopener noreferrer">Time dairy intake</a> such that it is not always paired with high oxalate foods.</li><li>Purchase dairy products that are fortified with calcium.</li><li>Consider a multivitamin-mineral supplement with about 100% of the daily recommended dose of nutrients (check the nutrition facts panel) as nutrition insurance if you are worried, but be sure to talk to your doctor first.<em></em></li></ul><p><em><a href="https://theconversation.com/profiles/jill-joyce-1172925" target="_blank" rel="noopener noreferrer">Jill Joyce</a> is an assistant professor of Public Health Nutrition at Oklahoma State University.</em></p><p><em>Disclosure statement: Jill Joyce does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond their academic appointment.</em></p><p><em>Reposted with permission from <a href="https://theconversation.com/anti-nutrients-theyre-part-of-a-normal-diet-and-not-as-scary-as-they-sound-149229" target="_blank" rel="noopener noreferrer">The Conversation</a>.</em></p>

Toxins enter the body through what we eat, drink, breathe in, and process in any way. Once inside, toxins overtax our immune system and detoxification system and leave us more vulnerable to illness — not ideal during cold and flu season, and especially not this year during a pandemic — and make us age a little faster, too.
1. Source Your Food Wisely<p>Try to stay away from packaged and processed foods that contain ingredients you can't pronounce, and instead reach for fresh food from natural sources. Aim to make vegetables more than 50% of your daily diet — their fiber is a great natural binder, and they're full of beneficial <a href="https://vitalplan.com/blog/the-case-of-the-missing-phytochemicals-and-how-to-get-them-back" target="_blank" rel="noopener noreferrer" style="">phytochemicals</a> — and minimize your red meat consumption.</p><p>Also, whenever practical, choose <a href="https://vitalplan.com/blog/how-to-eat-organic-without-spending-a-fortune" target="_blank" rel="noopener noreferrer">organic</a> over conventional products. That said, we know organic prices and accessibility can be an issue, so for help making strategic decisions, refer to the <a href="https://www.ewg.org/" target="_blank" rel="noopener noreferrer">Environmental Working Group</a> (EWG) "Dirty Dozen" and "Clean Fifteen" lists:</p><h3>The Dirty Dozen:</h3><ol><li>Strawberries</li><li>Spinach</li><li>Kale</li><li>Nectarines</li><li>Apples</li><li>Grapes</li><li>Peaches</li><li>Cherries</li><li>Pears</li><li>Tomatoes</li><li>Celery</li><li>Potatoes</li><li>Raisins*</li></ol><p><em>(*While raisins aren't technically a fresh food, the EWG found that they are "one of the dirtiest produce commodities on the market — and even some organic raisins are contaminated.")</em></p><h3>The Clean Fifteen</h3><ol><li>Avocado</li><li>Sweet corn</li><li>Pineapple</li><li>Onion</li><li>Papaya</li><li>Frozen sweet peas</li><li>Eggplant</li><li>Asparagus</li><li>Cauliflower</li><li>Cantaloupe</li><li>Broccoli</li><li>Mushrooms</li><li>Cabbage</li><li>Honeydew</li><li>Kiwi</li></ol>
2. Consider Detoxifying and Immune-Boosting Herbs<p>There are a number of herbs and natural ingredients that can help support detoxification and immune health. Here are the ones at the top of Dr. Rawls' list:</p><p><span></span><strong>Chlorella:</strong> This nutrient-rich freshwater algae binds to toxins so they can be eliminated from your body more efficiently. Chlorella works particularly well for withdrawing heavy metals. Pure chlorella can be purchased in the form of bulk powder, tablets, or capsules.</p><p><strong><a href="https://vitalplan.com/ingredients/milk-thistle" target="_blank">Milk Thistle</a>:</strong> It's been used for thousands of years to support a healthy liver, the primary organ responsible for detoxification.</p><p><strong>Dandelion:</strong> Known to help support liver function, research suggests <a href="https://vitalplan.com/ingredients/dandelion-extract" target="_blank">dandelion</a> helps promote the body's natural detoxification and elimination processes.</p><p><strong>Bitters:</strong> <a href="https://vitalplan.com/blog/the-impressive-health-benefits-of-bitter-foods" target="_blank">Bitter</a> flavors are important to digestion — they stimulate the release of the saliva, enzymes, and bile that help break down your food. Include bitter herbs and foods in each meal, or take a botanical extract that blends bitter herbs like dandelion root, burdock root, orange peel, and gentian root</p><p><strong>Reishi mushroom:</strong> An extensively studied adaptogenic mushroom, <a href="https://vitalplan.com/ingredients/reishi" target="_blank">reishi</a> has exceptional immunomodulating and antiviral properties. It helps normalize <a href="https://vitalplan.com/blog/are-you-inflammaging-how-to-stop-the-inflammation-that-speeds-up-aging" target="_blank">inflammatory</a> cytokines and promotes healthy immune response against threatening <a href="https://vitalplan.com/blog/the-immortal-life-of-your-microbiome" target="_blank" rel="noopener noreferrer">microbes</a>.</p><p><strong>Rhodiola:</strong> Another adaptogen, <a href="https://vitalplan.com/ingredients/rhodiola" target="_blank">rhodiola</a> improves stress tolerance by reducing fatigue, supporting energy levels, and improving tissue oxygenation.</p><p><span></span><strong><a href="https://vitalplan.com/ingredients/turmeric" target="_blank">Turmeric</a>:</strong> This popular spice is well loved for its anti-inflammatory and antioxidant properties.</p><p><strong>Shilajit:</strong> An herbo-mineral adaptogen, <a href="https://vitalplan.com/ingredients/shilajit" target="_blank">shilajit</a> has a long history of use in traditional Indian medicine for longevity and strength. It's also an immunomodulator with antioxidant, anti-inflammatory, and antiviral properties.</p><p><strong>Gotu Kola:</strong> Best known for improving memory and mood, <a href="https://vitalplan.com/ingredients/gotu-kola" target="_blank">gotu kola</a> is also great for promoting a normal response to inflammation, balancing stress hormones, and supporting circulation.</p>
3. Filter Your Water<p>Much of America's tap water has been shown to contain pollutants, so filtering what comes out of your kitchen sink is smart. To be sure you're using a filter that does the trick, keep these guidelines in mind:</p><ul><li>Look for a filter certified by NSF International or the Water Quality Association.</li><li>Choose one that removes the contaminants in your water (check your local drinking water quality report to see what's present).</li><li>Change your water filters on time.</li></ul>
4. Choose Safe and Effective Cleaning Supplies<p>When buying household cleaning products, don't bring home chemicals that could harm your health more than some of the microbes you're trying to get rid of. Fortunately, there are a number of products on the market that work safely; here are some ways to shop wisely:</p><ul><li>Look for the Green Seal, Ecologo, or Safer Choice (EPA) seals.</li><li>Opt for fragrance-free options.</li><li>Avoid triclosan and quaternary ammonium compounds or "quats." (One tactic is to choose products that don't advertise as "antibacterial.")</li><li>Consult the EWG's list of <a href="https://www.ewg.org/news-and-analysis/2020/03/16-effective-and-safe-products-guard-against-coronavirus" target="_blank" rel="noopener noreferrer">safe and effective products</a> for guarding against coronavirus.</li></ul>
5. Opt for Non-Toxic Beauty and Personal Care Products<p>There are a lot of claims made on beauty and self-care products these days, but words alone, like "natural," "organic," "non-toxic," "clean," "green," and "eco-friendly," don't mean a thing — they aren't backed by any sort of regulatory or certification processes. Instead, to find non-toxic products you trust, you have to do a little research.</p><p>Start by checking reputable ratings databases like <a href="https://www.ewg.org/skindeep/" target="_blank" rel="noopener noreferrer">Skin Deep</a> (EWG) and <a href="https://www.thinkdirtyapp.com/" target="_blank" rel="noopener noreferrer">Think Dirty</a>. Another good bet: Look for reliable third-party certifications on products labels, including:</p><ul><li>USDA Organic</li><li>EWG Verified</li><li>Made Safe</li><li>NSF/ANSI 305</li><li>Natural Products Association Certified</li><li>Whole Foods Market Premium Body Care</li></ul>
6. Get Outside<p>One more reason to <a href="https://vitalplan.com/blog/how-to-feel-great-and-boost-longevity-in-just-17-minutes-a-day" target="_blank" rel="noopener noreferrer" style="">get outdoors</a> beyond combatting cabin fever: The air in natural environments is generally much cleaner than indoor air. For one, outdoor air contains ⅔ less carbon dioxide, high levels of which negatively affect our productivity, <a href="https://vitalplan.com/blog/natural-sleep-aids" target="_blank" rel="noopener noreferrer" style="">sleep</a>, and more.</p><p>Forest air in particular contains phytoncides, organic compounds emitted by trees and plants that have been shown to boost our immune system function, plus plants in general help neutralize toxic substances in the air. Forests, open spaces, and open water are also rich in negative ions, which reduce inflammation.</p><p>So take your pick of natural environs, and get out there as often as possible — while still maintaining at least 6 feet of distance between yourself and others, of course.</p>
7. Bring Nature Indoors<p>Plants are natural air purifiers, so bringing some plants indoors can help clear the air in your home. Here's a list of the top 10 air-purifying plants to consider:</p><ul><li>Areca palm</li><li>Lady palm</li><li>Bamboo palm</li><li>Rubber plant</li><li>Dracaena</li><li>English ivy</li><li>Dwarf date palm</li><li>Ficus</li><li>Boston fern</li><li>Peace lily</li></ul>
8. Drive Less, Move More<p>Staying off the roads decreases air pollution, and the fact that many of us are driving less these days is noticeably improving air quality. If your commute is on hold, try to translate some of your usual travel time into getting more physical activity, or sneak in more movement between other normal routines.</p><p>Exercise improves circulation, oxygenates your tissues, and enhances the work of the lymphatic system through muscle contractions — all of which make it easier to move toxins out of your body.</p>
9. Practice Forgiveness<p>Through the practice of gratitude, we stay centered and in the present moment. This allows us to move through situations from our heart. Take time to forgive someone or yourself for things in the past. When we forgive, we expand and open up to endless possibilities.</p>
10. Quit a Bad Habit<p>Are you a smoker? Pack rat? Chronically sleep-deprived? In a bad relationship? Toxins come into our lives in many forms. Consider if you're participating in any unhealthy patterns or holding onto anything that no longer serves you, and then find a way to limit those things in your life.</p>
