The first day of summer is sneaking up and almost here! Father’s Day is tomorrow…these long June days are the best days of the year in my opinion. Just love ‘em. The fireflies are starting to flit in the balmy night air and my kids are pretty excited about that. What do you love about summer?
Anyway…here’s some good news for y’all!
‘Craigslist’ for Volunteers to Debut Soon
A group of nonprofits, technology developers, and more are about to unveil a new website called All for Good. The site is currently managed by Google and will provide a wide variety of information about volunteer positions and events.
The project has attracted support from Craig Newmark of Craigslist and Arianna Huffington of the Huffington Post. There has also been active participation from many nonprofit groups that have agreed to share their volunteer opportunities on the site.
The coalition has released an “alpha” version of the website and plans to showcase the project at the National Conference on Volunteering and Service later this month.
Today’s Dairy Farms Use Less Land, Feed and Water
Improved dairy genetics, nutrition, herd management and animal welfare have resulted in more efficient milk production with a smaller carbon footprint.
A recent study compared 1944 milk production with 2007. The study showed that the carbon footprint for a gallon of milk produced in 2007 was only 37% for the same amount of milk produced in 1944. Improved efficiency has enabled the U.S. dairy industry to produce 186 billion pounds of milk from 9.2 million cows in 2007. In 1944, 117 billion pounds of milk from 25.6 million cows was produced.
Additionally, modern dairy systems only use 10 percent of the land, 23 percent feed, and 35 percent of the water that was required to produce the same amount of milk in 1944. Also, 2007 farming produced 24% of the manure and 43% of the methane per gallon of milk compared to 1944.
Is the Sky the Limit for Wind Power?
A new study has identified New York as a prime location for exploiting high-altitude winds. These winds may contain enough energy to meet world demand 100-fold.
A new global survey of wind energy available at high altitudes in the atmosphere was compiled. Researchers assessed potential for wind power in terms of “wind power density.”
“There is a huge amount of energy available in high altitude winds,” said coauthor Ken Caldeira. “These winds blow much more strongly and steadily than near-surface winds, but you need to go get up miles to get a big advantage. Ideally, you would like to be up near the jet streams, around 30,000 feet.”
There is enough power in these high altitude winds to fuel all of modern civilization, however, there are still times when the winds are not blowing. The wind can be expected to stop about five percent of the time. This means there has to be back-up power or a way to store large amounts of energy. High-altitude wind may be a potentially major energy source but it will require substantial infrastructure.
