Blizzard Helps Scientists Visualize Airflow Around Large Wind Turbines

Yale Environment 360 - June 25, 2014
A Minnesota blizzard has helped scientists understand airflow patterns around large wind turbines, paving the way for more efficient turbine designs and wind farm

Watch Video

Airflow patterns are visible during blizzard. configurations, researchers report in Nature Communications. Wind farms lose roughly 10 to 20 percent of the potential energy they could harvest, and complex airflow patterns play the largest role in those energy losses. Studying airflow around large turbines, which can be more than 100 meters tall, is not feasible in lab settings, so scientists typically test smaller turbine models in wind tunnels and use tracer particles to visualize airflow patterns. Researchers from the University of Minnesota realized they could scale up their experiments to real-world conditions by using heavy snowfall during a blizzard to trace airflow patterns, as shown in this video. Their findings show that airflow patterns under real-world conditions differ from smaller-scale laboratory tests in important ways, and those differences should be taken into account when designing turbines and wind farms.

Concentrated Solar Power Could Compete with Natural Gas, Study Says

Yale Environment 360 - June 24, 2014
Concentrated solar power (CSP) could meet a substantial percentage of current energy demand in some parts of the world, according to research

CSP plant in San Bernardino County, CA published in the journal Nature Climate Change. In the Mediterranean region, for example, the study shows that a grid-connected CSP network could provide 70 to 80 percent of current electricity demand, at no extra cost compared to natural gas-fired power plants. CSP could also feasibly meet energy demands in parts of southern Africa, according to researchers. CSP systems use mirrors or lenses to concentrate solar rays into a small area. The concentrated energy heats a liquid that produces steam to drive turbines, which means that the collected energy can be stored as heat and converted to electricity when needed — a major advantage over solar panels, which store energy much less efficiently.

BLOG: Celebrating ’5th Birthday and Beyond’

Operation USA - June 20, 2014

Operation USA is proud to be a coalition partner in the ’5th Birthday and Beyond’ campaign. Read on to learn why we’re helping to celebrate more 5th birthdays around the world, and what you can do to get involved!

For many families, a child’s fifth birthday is just one of many milestones to be celebrated in his/her young life. But, did you know that there is a staggering number of children around the world who never make it to the age of five? Millions of children’s lives are cut short each year due to poverty, hunger and disease. Despite major progress in global health (thanks in large part to the United States!) there are still 6.6 million children who will die this year, mainly from preventable diseases. Fortunately, there are steps each of us can take to help reduce the number of child deaths each year and continue to help more children worldwide not only to survive, but also to thrive, after the age of five.


Richard Walden, CEO of Operation USA, at five years old

Over the past two decades, the United States has played a leading role in preventing the deaths of millions of children under the age of five. This year, six million fewer children will die before their fifth birthday than just 25 years ago. U.S. foreign assistance has played a leading role in achieving these results, dramatically improving children’s health and survival worldwide. In just 12 short years, deaths from diseases such as pneumonia, malaria, diarrhea, measles and AIDS have dropped significantly, according to data compiled by UNICEF.

The United States has also played a leading role in the reduction of sicknesses around the world. Today, 10 million people are walking, spared the crippling effects of polio thanks to the global polio eradication program led by the U.S. government, UNICEF, WHO, Rotary International and the Gates Foundation.*

With the support of the American people, U.S. foreign assistance programs have helped cut in half the annual number of deaths of children under five since 1990. These results are due in large part to the historic collaboration between the world’s governments, multilateral institutions and local players. In addition, diverse allies such as NGOs (like Operation USA), civic groups, faith and business communities, universities and philanthropies have come together to leverage billions more private dollars for overseas health and development programs.

While much progress has been made over the past 25 years, we still have far to go. An estimated 6.6 million children won’t reach their fifth birthday this year. That’s 18,000 children a day who still don’t reach that milestone. Forty-four percent of those deaths occur during the newborn period, and many are due to preventable diseases. Now is the time to re-commit our investments in life-saving programs, providing millions of children the opportunity to survive and thrive beyond their fifth birthday!

Five easy ways to get involved:
1) Visit 5thbdayandbeyond.org to get the facts, upload your fifth birthday photo and join the movement.
2) Make a donation in support of effective interventions such as bed nets, immunizations, anti-retroviral medications, clean water and toilets, better nutrition and quality care at birth.
3) Help us share this message on Facebook and help more children reach age five.
4) Show your support by sharing your commitment with the #5thbday tag on Twitter.
5) Research ’5th Birthday and Beyond’ causes in your local community for opportunities to volunteer your time or get involved in hands-on projects.

Average Summer Temperatures in U.S. Have Risen Up To 5 Degrees Since 1970

Yale Environment 360 - June 20, 2014
Summer temperatures in the U.S. have been rising on average 0.4 degrees F per decade since 1970, or about

Average summertime temperature increases 2 degrees F overall, but the Southwest and West regions have borne the brunt of those increases, according to an analysis by Climate Central. In the Southwest, temperatures have risen an average of 0.6 degrees per decade, with a few localized areas warming as much as 0.9 degrees per decade. In the West, some parts of California and Nevada have warmed 1.32 degrees F per decade, or more than 5 degrees total since 1970. On the other end of the spectrum, the Upper Midwest has seen the lowest increases. Temperatures in that region have increased only 0.1 degree F per decade on average. The National Climate Assessment, released last month, found that annual average temperatures in the U.S. could increase by 10 degrees F before the end of the century if the rate of greenhouse gas emissions doesn't slow.

Rerouting Flights to Avoid Contrails Would Slow Climate Change

Yale Environment 360 - June 19, 2014
Rerouting the flight paths of commercial aircraft to minimize the condensation trails, or contrails, they leave behind would help slow global warming, even if

Alternate flight paths to avoid contrail formation the new flight path is longer, according to research published today. Contrails, thin clouds composed of ice crystals condensed from an aircraft's exhaust, can persist for 17 hours or more and are likely the single largest contributor to climate change associated with aviation. They form when a plane passes through parts of the atmosphere that are very cold and moist, usually near high pressure systems. The new research shows that avoiding contrail formation has greater climate benefits than avoiding additional carbon dioxide emissions associated with slightly longer flight routes. For example, for a small aircraft that is predicted to form a contrail 20 miles long, an alternative path that adds less than 200 miles will have a smaller climate impact than the contrail. For a larger aircraft, which emits more CO2 per mile than a smaller plane, the alternative route is preferable if it adds less than 60 miles, according to researchers from the University of Reading.

Global Energy Sector Must Prepare for Climate Change, Report Says

Yale Environment 360 - June 18, 2014
Power plants and energy systems around the world will experience potentially disastrous effects from climate change and should develop plans for dealing with those effects, according to a report released today by the World Energy Council and European researchers. Long-term droughts, for example, could threaten water supplies needed to cool large power plants as they produce electricity, the report notes. Many energy facilities are also lacking protection from floods, rising seas, and severe weather events — a problem highlighted by the 2011 Fukushima nuclear disaster. Strong global political action could have major impacts on the energy sector, the report says, especially if governments make a coordinated effort to invest in renewable and low-carbon energy and upgrades to power distribution grids.
