What Would JFK Have Said About the Energy Challenges of Our Times?
By John Rogers
Maybe it's because I first started working on clean energy while serving in the Peace Corps he founded, or maybe it's my years of working on these issues from his home state. But I can't help thinking about the 100th anniversary of John F. Kennedy's birth, and connecting his stirring rhetoric to the energy challenges of our times.
Here's what our 35th president might have said about the challenges of energy transition and the opportunities in clean energy:
"Change is the law of life. And those who look only to the past or present are certain to miss the future."
This tidbit of wisdom from the Sage of Hyannis needs no updating to make it applicable to clean energy. Our electricity sector has gone through a lot of changes since Thomas Edison set up the world's first electrical grid on the Lower East Side in 1882. But we're clearly in a time of unparalleled transformation.
Yeah, that means over time we have to figure out new business models to make it all hold together. But a clean energy future is one we want to make certain not to miss, so it's worth figuring out.
"We choose to [do clean energy]… not because [it is hard], but because [it is easy]."
This one required just a bit of tweaking. In his famous 1962 "moon" speech at Rice University, Kennedy suggested, "We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard…"
In our case, though, in a lot of ways, clean energy is actually the easier route. Yes, there are (again) issues of financial engineering—who gets compensated, and how, when part of the power is coming from my own roof, for example. And there are some technical issues (though fewer than opponents would have you think) as more solar and wind power add variability to the electricity supply-demand picture, for example.
But think about power plants like solar and wind ones that require no fuel delivery. How about not having to worry about air or water pollution, or water use, or catastrophic failures? How about being able to spend more energy dollars on people, and less on million-year-old rock? How about meeting energy demand with less energy, not more, with efficient lighting, motors and appliances?
Sure sounds simpler.
"Let us not seek the Republican answer or the Democratic answer, but the right answer."
Here again, JFK was right on the first time around. People from across the political spectrum find plenty to love in clean energy.
Clean energy means jobs, in manufacturing, installation, servicing and so much more. It can mean revenues for communities and landowners who host renewable energy. For farmers and ranchers, for example, as a dairy farmer in upstate New York put it to me recently, wind farms can be "a godsend."
Similarly, on pollution: Whatever box they check on voter registration forms, people want healthy air and clean water for their communities and their kids.
Clean energy's broad appeal means that we can find leadership and support in a range of places (and colors). In our recent analysis of state leadership on clean energy momentum, six of the top states overall are headed by Democrats, and four by Republicans. And a solid majority of Americans across the country support action on renewable energy, including funding research (more than four out of five) and even requiring utilities to get at least 20 percent of their electricity from renewables (two out of three).
Clean energy is so often the right answer, regardless of what politics are flavoring the question.
"Ask not what your [grid] can do for you… ask what you can do for your [grid]."
What is arguably JFK's most famous quote, from his inaugural address, invited us to rethink our relationship to our country, to reposition ourselves not just as recipients, but as contributors. In the energy world, distributed energy technologies have dramatically improved our chances of doing that in recent years.
In our recent clean energy momentum state ranking, one of our metrics had to do with that changing relationship, via solar. "The arrival of affordable rooftop solar," we suggested, "represents a major shift in the connections between households and their electricity supplies."
Harnessing the power of sunbeams and silicon, we can turn our roofs into mini power plants, and generate electricity not just to meet our own needs but to help utilities and the local electricity grids meet peak power demands on hot, sunny days. Actually, a range of new technologies (energy storage, anyone?) and approaches are letting us be much more active participants in making the electricity grid work for all.
So go ahead, ask what you can do for your grid. The answer is plenty.
"Efforts and courage are not enough without purpose and direction."
Right again. So we move to clean energy, with purpose and direction (we hope), because we can, and because we must. In his moon speech, after the part about "easy" and "hard," JFK went on to say this about aiming high:
"…because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone and one which we intend to win…"
Unwilling to postpone, and intending to win. Words to live by.
Happy birthday, Mr. President. And thanks.

Since even moderate-intensity workouts offer a slew of benefits, walking is a good choice for people looking to stay healthy.
How to Rock Your Walk<p>Walking isn't just fun and healthy. It's accessible.</p><p>"Walking is cheap," says Dr. John Paul H. Rue, a sports medicine doctor at <a href="https://mdmercy.com/" target="_blank">Mercy Medical Center in Baltimore</a>. "You can do it anywhere at any time; [it] requires little to no special equipment and has many of the same cardio benefits as running or other more intense workouts."</p><p>Want to up your walking game? Try the tips below.</p>
Use Hand Weights<p>Cardio and strength training can go hand-in-hand when you add weights to your walk.</p><p>A <a href="https://journals.lww.com/acsm-msse/Fulltext/2019/03000/Associations_of_Resistance_Exercise_with.14.aspx" target="_blank">2019 study</a> found that weight training is good for your heart, and <a href="https://www.mayoclinicproceedings.org/article/S0025-6196(17)30167-2/abstract" target="_blank">research</a> shows it reduces the risk of developing a <a href="https://www.healthline.com/health/nutrition-metabolism-disorders" target="_blank">metabolic disorder</a> by 17 percent. People with metabolic disorders have a higher chance of being diagnosed with high cholesterol, high blood pressure, and diabetes.</p><p>Rue suggests not carrying weights for your entire walk.</p><p>"Hand weights can give you an added level of energy burning, but you have to be careful with these because carrying [them] over a long period of time or while walking could actually lead to some overuse injuries," he says.</p>
Make It a Circuit<p>As another option, consider doing a circuit. First, put a pair of dumbbells on your lawn or somewhere in your home. Walk around the block once, then stop and do some bicep curls and tricep lifts before walking around the block again.</p><p>Rue recommends <a href="https://www.healthline.com/health/exercise-fitness/running-with-weights" target="_blank">avoiding ankle weights</a> during cardio workouts, as they force you to use your quadriceps rather than hamstrings. They can also cause muscle imbalance, according to the <a href="https://www.health.harvard.edu/staying-healthy/wearable-weights-how-they-can-help-or-hurt" target="_blank">Harvard Health Letter</a>.</p>
Find a Fitness Trail<p>Strength training isn't limited to weights. You can get stronger by <a href="https://www.healthline.com/health/bodyweight-workout" target="_blank">simply using your body</a>.</p><p>Often found at parks, fitness trails are obstacle courses with equipment for pullups, pushups, rowing, and stretches to build upper and lower body strength.</p><p>Try searching "fitness trails near me" online, checking out your local parks and recreation website, or calling the municipal office to <a href="https://calisthenics-parks.com/" target="_blank">find one</a>.</p>
Recruit a Friend<p>People who workout together stay healthy together.</p><p><a href="https://bmcgeriatr.biomedcentral.com/articles/10.1186/s12877-017-0584-3" target="_blank">One study</a> showed that older adults who exercised with a group improved or maintained their functional health and enjoyed their lives more.</p><p>Enlist the help of a walking buddy with a regimen you aspire to have. If you don't know anyone in your area, apps like <a href="https://www.strava.com/" target="_blank">Strava</a> have social networking features so you can get support from fellow exercisers.</p>
Try Meditation<p>According to the <a href="https://www.nccih.nih.gov/research/statistics/nhis/2017" target="_blank">2017 National Health Interview Survey</a>, published by the National Institutes of Health, meditation is on the rise, and for good reason.</p><p>Researchers <a href="https://pubmed.ncbi.nlm.nih.gov/29616846/" target="_blank">found</a> that mind-body relaxation practices can regulate inflammation, <a href="https://www.healthline.com/health/biological-rhythms" target="_blank">circadian rhythms</a>, and <a href="https://www.healthline.com/health/glucose" target="_blank">glucose</a> metabolism, as well as lower <a href="https://www.healthline.com/health/high-blood-pressure-hypertension" target="_blank">blood pressure</a>.</p><p>"Any form of exercise can be turned into a meditation of some type, either by the surroundings you are walking in, like a park or trail, or by blocking out the outside world with music on your headphones," Rue says.</p><p>You can also play a podcast or download an app like <a href="https://www.headspace.com/headspace-meditation-app" target="_blank">Headspace</a> that has a library of guided meditations to practice while you walk.</p>
Do Fartlek Walks<p>Typically used in running, fartlek intervals alternate periods of increased and decreased speed. These are <a href="https://www.healthline.com/nutrition/benefits-of-hiit" target="_blank">high-intensity interval training (HIIT)</a> workouts, which allow exercisers to accomplish more in less time.</p><p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0154075" target="_blank">One study</a> showed that 10-minute interval training improved <a href="https://www.healthline.com/health/metabolic-syndrome" target="_blank">cardiometabolic</a> health, or lowered the risk of heart disease, stroke, and diabetes, just as well as working out at a continuous pace for 50 minutes.</p><p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0111489" target="_blank">Research</a> also shows that HIIT workouts increase muscle <a href="https://www.healthline.com/health/fast-twitch-muscles" target="_blank">oxidative</a> capacity, or the ability to use oxygen. To do a fartlek walk, try walking at an increased pace for 3 minutes, slow down for 2 minutes, and repeat.</p>
Gradually Increase Pace<p>A faster walking pace is associated with a lower risk of <a href="https://www.healthline.com/health/copd" target="_blank">chronic obstructive pulmonary disease (COPD)</a> and respiratory diseases, according to a <a href="https://pubmed.ncbi.nlm.nih.gov/30303933/" target="_blank">2019 study</a>.</p><p>Still, it's best not to go from a stroll to an Olympic-worthy power walk in a day. Instead, increase your pace gradually to prevent injury.</p><p>"Start by walking at a brisk pace for about 10 minutes per day, 3 to 5 days per week," Rue says. "Once you've done this for a few weeks, increase your time by 5 to 10 minutes per day until you get to 30 minutes."</p>
Add Stairs<p>You've likely heard that taking the stairs instead of an elevator is a way to add more movement into your daily routine. It's also a way to step up your walking. Stair climbing has been shown to <a href="https://www.sciencedirect.com/science/article/pii/S2211335519301123?via%3Dihub" target="_blank">decrease the risk of mortality</a> and can easily add a bit more challenge to your walk.</p><p>If you don't have stairs in your home, you can often find them outside a local municipal building, train station, or at a high school stadium.</p>
Is Your Walk a True Cardio Workout?<p>Not all walks are equal. A walk that's too leisurely may not provide enough burn to qualify as cardio. To see if you're getting a good workout, try to <a href="https://www.healthline.com/health/how-to-check-heart-rate" target="_blank">measure your heart rate</a> using a monitor.</p><p>"A target goal for a good walking workout heart rate is about 50 to 70 percent of your maximum heart rate," Rue says, adding that maximum heart rate is <a href="https://www.healthline.com/health/fitness-exercise/fat-burning-heart-rate" target="_blank">typically calculated</a> by 220 beats per minute minus your age.</p><p>You can also monitor how easily you can carry on a conversation while you walk to gauge your heart rate.</p><p>"If you can walk and carry on a normal conversation, that's probably a lower intensity walk," says Rue. "If you are slightly breathless but can still have a conversation, that's probably a moderate workout. If you are out of breath and can't talk normally, that's a vigorous workout."</p>
Takeaway<p>By shaking up your routine, you can add excitement to your workout and reap even more rewards than a basic walk provides. Increasing the pace and intensity of a workout will make it more effective.</p><p>Simply pick your favorite variation to add some spice to your next walk.</p>

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.
The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.
