The NY Times Got It Wrong: Renewable Energy Is Key to Fighting Climate Change
By Noah Long and Kevin Steinberger
Renewable energy is one of the most effective tools we have in the fight against climate change and there is every reason to believe it will succeed. A recent New York Times column seems to imply that renewable energy investments set back efforts to address climate change—nothing could be further from the truth. What's more, renewable technologies can increasingly save customers money as they displace emissions from fossil fuels.
The U.S. must continue—and accelerate—its clean energy growth and the transition to a low-carbon electric grid.
Wind and solar energy have experienced remarkable growth and huge cost improvements over the past decade with no signs of slowing down. Prices are declining rapidly and renewable energy is becoming increasingly competitive with fossil fuels all around the country. In some places, new renewable energy is already cheaper than continuing to operate old, inefficient and dirty fossil fuel-fired or nuclear power plants.
In fact, the investment firm Lazard estimates that the cost of generating electricity from wind and solar has declined by 58 percent and 78 percent, respectively, since 2009. Those cost trends are expected to continue and coupled with the recent extension of federal tax credits for renewable energy, wind and solar growth is widely expected to accelerate over the next several years, with capacity projected to double from 2015 levels by 2021. With careful planning, renewable energy and clean energy options like increased energy efficiency and storing energy for use later will help pave the way.
In the longer term, the U.S. Environmental Protection Agency's Clean Power Plan to establish the first national limits on carbon pollution from power plants will continue to drive renewable energy growth. Wind and solar energy will play a central role in achieving the emissions cuts required and carbon policies like the Clean Power Plan will be critical to ensuring that low-carbon resources are prioritized over higher-emitting power plants.
The Benefits are Huge
In addition to the climate benefits that they will help deliver, renewables already provide a wide range of market and public health benefits that far outweigh their costs. A recent report from the Department of Energy and Lawrence Berkeley National (LBNL) Laboratory found that renewable portfolio standards—state policies that mandate that a specific amount of the state's electricity comes from renewables—provide a wide range of economic, health and climate benefits. The report concluded that in 2013 alone, renewable standards across the country saved customers up to $1.2 billion from reduced wholesale electric prices and $1.3 billion to $3.7 billion from lower natural gas prices (as a result of lower demand for natural gas across the power sector).
The non-market benefits of renewable energy also are considerable. The LBNL researchers estimated that renewables supported nearly 200,000 jobs, provided $5.2 billion worth of health benefits through improved air quality and resulted in global climate benefits of $2.2 billion. At the same time, according to a separate report by DBL Investors, the top 10 leading renewable states experienced lower electricity price increases than the bottom 10 states between 2002 and 2013.
The U.S. must continue—and accelerate—its clean energy growth and the transition to a low-carbon electric grid. There will be technical challenges to completing this transformation, but study after study concludes that integrating high levels of renewables into our electric grid is achievable. This is also being demonstrated in practice, as many states are already incorporating wind and solar, including in Texas, where wind has now supplied more than 45 percent of the state's total energy demand on multiple occasions and in Iowa, as the state now generates 31 percent of its total annual power from wind.
Change is Here
Much is said about the need to adapt the electric grid to the variability associated with integrating renewable energy into our electricity mix. Until recently, the huge costs of maintaining back-up generation and transmission in case they're needed to keep the lights on when large, inflexible resources like coal and nuclear plants suddenly and unexpectedly go offline has too often been ignored. Grid managers and planners are now appropriately as concerned about the need for flexibility and predictability, assets that large fossil and nuclear plants lack. Renewable energy production is variable, but predictable (we mostly know when it will be sunny or windy). However, it can be impossible to predict when large fossil or nuclear plant will have to shut down for critical maintenance.
In a sign of the declining status of large, inflexible base load resources, PG&E recently announced it will close the Diablo Canyon nuclear plant in California and replace it with 100 percent clean energy (NRDC is a signatory), PG&E explains: "California's electric grid is in the midst of a significant shift that creates challenges for the facility in the coming decades. Changes in state policies, the electric generation fleet and market conditions combine to reduce the need for large, inflexible baseload power plants."
As we move forward, there are a number of grid planning practices and technologies that will help facilitate America's transition to higher and higher amounts of renewable energy. For example, as more and more cars on the road become electric, those vehicles can help store electricity and manage peak demand so that supply and demand can be better aligned. Demand response (compensating customers for altering their electricity use at specific periods) and time of use electricity pricing can provide similar support. Leading states are currently contemplating how to design policies and market structures that support a modernized, low-carbon grid. Planning for the future can and must be done in parallel with promoting strong renewables growth in the present.
Renewable energy is already helping address climate change. It's time to put our feet on the accelerator.

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>
