Renewable Energy Races Ahead as Nuclear and Fossil Fuels Falter
The case for renewable energy received a boost this week as the wind industry revealed that over 1 gigawatt (GW) of offshore wind capacity—enough to power up to 1 million homes—was connected to the European grid over the first half of 2013.

This is almost double the amount added during the same period last year, a rise which has been driven in large part by growth in the UK. The UK led the way with 146 turbines boasting 514 megwatts (MW) of capacity connected from a series of new wind farms, including major projects at Gunfleet Sands, Lincs, Teesside and the London Array, the world’s largest wind farm, which was officially inaugurated this month.
Denmark and Germany also made significant contributions to this growth trend, adding 353MW and 105MW of new offshore wind capacity, respectively. An additional 5.7GW of new offshore wind farms are currently in the pipeline for Europe, with a potential to deliver clean energy for close to 6 million homes.
The European solar industry also posted strong achievements, as Germany smashed its record for solar output by reaching 23.4 GW of electricity from photovoltaics (PV) on June 6—enough to power the equivalent of 2.3 million homes, almost 40 percent of Germany’s electricity need. According to the Federal Network Agency, Germany installed a total of 33.5 GW of PV by the end of April 2013.
Meanwhile, nuclear power is on the rocks, according to a new report by the World Nuclear Industry, which says that globally, nuclear energy output is on a steady decline and the technology is losing more and more of its share in the global energy mix.
Despite all these positive achievements, it is increasingly clear that renewable energy projects face a challenging environment in Europe, as governments continue to flip-flop unreliably over support mechanisms for the industry.
The renewables industry and clean energy campaigners have raised concerns that governments are doing little to harness the potential of popular and prosperous wind farms and solar plants across the continent. Many European governments are mired in an ideological back and forth over renewable energy policies. Their concerns were validated by the news that Spanish, British and German policy support mechanisms for renewable energy face retroactive cuts and re-evaluation this week.
Justin Wilkes, director of policy at the European Wind Energy Association, said:
"Offshore wind is a new industry that creates jobs, reduces fossil fuel imports and in which Europe is a world leader with huge export opportunities. The installation rate shows what the European offshore wind industry is now capable of. But to attract investment to the sector governments need to provide a stable regulatory framework and the EU should set a binding renewable target for 2030."
This week the Spanish government will slash the profit of renewable energy companies in an effort to recoup debts, costing utilities €2.7 billion and consumers €900 million. Spain’s wind industry lobby group, the Asociacion Empresarial Eolica, said it expects a “cascade of financial problems” as a result of the reforms. In an emailed statement they say that “this changes the conditions for investments made by the sector over more than 20 years … with this reform, the government is increasing even more the uncertainty affecting the industry.”
In the UK, long-term subsidies for wind farms are to be cut by a quarter, the government will announce this week—a move which the wind power industry say will leave billions of pounds of investment and thousands of jobs “hanging in the balance.” This news comes as the EU announces an investigation into Germany’s renewable energy law which may have breached certain competition rules, according to Der Spiegel.
These events have had a knock-on effect by scaring investors away from a recession busting industry that represents thousands of jobs and billions of pounds of investment in the UK alone. New UK survey data shows that four out of five people want to switch from fossil fuels to renewables, but they are worried about fickle governments and profiteering utilities that make the green energy transition more risky than necessary.
Professor Nick Pidgeon of the UK Energy Research Centre said:
"The British public backs a green energy future looking into the long term, but there is an issue of distrust currently both with the energy companies and the government which may block or be a problem for realizing that vision."
The renewables industry and clean energy campaigners are calling for governments to show more reliable, long-term support for prosperous and popular renewables.
These strong calls from clean energy campaigners and industries come as renewables emerge more clearly as the smart energy choice of the future. Recent reports have shown that if we want to prevent disastrous levels of global warming then we must keep two thirds of known fuel reserves in the ground and severely limit the amount of carbon intensive fuels, like coal, that can be burnt in the future.
Seminal work from the Carbon Tracker shows that this “two thirds safety limit” means that investment in expanding fossil fuel projects are increasingly risky and efforts to change the pattern of investment in dirty fuels are stepping up a gear in Europe.

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.
