What’s blowing in the wind?

Dear EarthTalk: What is the latest prognosis for wind energy to command a larger piece of the renewable energy pie?

Hydroelectric sources of power dwarf other forms of renewable energy, but wind power has been a dominant second for years, and continues to show “hockey stick” growth moving forward. According to the Global Wind Energy Council (GWEC), global cumulative installed wind capacity — the total amount of wind power available — has grown 50-fold in less than two decades, from just 6,100 megawatts (MW) in 1996 to 318,137 MW in 2013. 

And the future looks brighter still. Analysts from Bloomberg New Energy Finance (BNEF) predict that wind will account for the largest share — 30 percent — of new renewables added to the global power grid by 2030. That new renewables are expected to account for as much as 70 percent of all new power sources over the next 20 years means that wind is poised to become a major player on the global energy scene. 

Here in the U.S., energy generated by domestic wind farms has nearly tripled in just the past four years, despite a brief hiccup due to a lapse in the Production Tax Credit, a renewable energy production incentive that effectively subsidizes the creation of more wind farms. But even despite this, wind represented about a third of all new power added to the U.S. grid over the past five years. The Natural Resources Defense Council (NRDC), a leading environmental non-profit and wind power advocate, forecasts that the U.S. will derive some 20 percent of its total electricity production from wind by 2030.

“The U.S. industry has many reasons for favorable long-term prospects,” reports the American Wind Energy Association (AWEA), a nonprofit trade group representing the wind industry. “In addition to the record activity at the end of 2013, wind energy helped keep the lights on and insulate against temporary price spikes during the recent ‘polar vortex’ cold weather snap, demonstrating the value of wind power in a balanced energy portfolio.” 

AWEA also points out recent reports showing how incorporation of wind energy lowers costs for electric consumers. “And critical to some parts of the country facing continuing drought, wind energy uses no water in its production, as well as releasing no emissions,” adds the group.

The fact that wind energy in the U.S. avoids some 100 million tons of carbon dioxide emissions annually is also good news. AWEA adds that that number will grow as wind energy scales up to 20 percent of the grid and beyond “making the addition of more wind power one of the fastest, cheapest, and largest-scale ways for states to meet the Administration’s new goals for reducing carbon pollution from power plants.”

While wind continues to grow fast, solar may finally be catching up. According to BNEF, some 36.7 gigawatts (GW) of new solar photovoltaic capacity were added worldwide in 2013 compared with 35.5 GW worth of new wind power installations. BNEF adds that global demand for wind turbines may actually shrink in 2014 (by five percent), representing the first such decline since 2004. But Justin Wu, head of wind analysis for BNEF, says it’s just a temporary blip: “Falling technology costs, new markets and the growth of the offshore industry will ensure wind remains a leading renewable energy technology.”

A new life for Barrington Hall

A new life for Barrington Hall

Barrington Hall in Great Barrington has hosted generations of weddings, proms and community gatherings. When Dan Baker and Daniel Latzman took over the venue last summer, they stepped into that history with a plan not just to preserve it, but to reshape how the space serves the community today.

Barrington Hall is designed for gathering, for shared experience, for the simple act of being together. At a time when connection is often filtered through screens and distraction, their vision is grounded in something simple and increasingly rare: real human connection.

There is a moment, looking at a painting by Gail Rothschild, when you realize you are not looking at a painting so much as a map of time. Threads become brushstrokes; fragments become fields of color; something once held in the hand becomes something you stand in front of, both still and in a constant process of changing.

“Textiles connect people,” Rothschild said. “Textiles are something that we’re all intimately involved with, but we take it for granted.”

For a century, the Sherman Players have turned a former 19th-century church into a stage where neighbors become castmates, volunteers power productions and community is the main attraction. The company marks its 100th season with a lineup that blends classic works, new writing and homegrown talent.

New England has a long history of community theater and its role in strengthening civic life. The Sherman Players remain a vital example, mounting intimate, noncommercial productions that draw on local participation and speak to the current cultural moment.

For those curious about opera but unsure where to begin, the Mahaiwe Theater in Great Barrington will offer an accessible entry point with “Once Upon an Opera,” a free, family-friendly program on Sunday, April 12, at 2 p.m. The event is designed for opera newcomers and aficionados alike and will include selections from some of opera’s most beloved works.

Luca Antonucci, artistic coordinator, assistant conductor and chorus master for the Berkshire Opera Festival, said the idea first materialized three years ago.

A tradition of lamb for Easter and Passover

Preparing lamb for the observance of Easter is a long-standing tradition in many cultures, symbolizing new life and purity. For Christians, Easter marks the end of Lenten fasting, allowing for a celebratory feast. A popular choice is roast lamb, often prepared with rosemary, garlic or lemon. It is traditional to serve mint sauce or mint jelly at the table.

The Hebrew Bible suggests that the last plague God inflicted on the Egyptians, to secure the Israelites’ release from slavery, was to kill the firstborn son in every Egyptian home. To differentiate the Israelites from the Egyptians, God instructed them to mark their doorposts with the blood of a lamb. Today, Jews, Christians and Muslims generally believe that God would have known who was Israelite and who was Egyptian without such a sign, but views of God’s omnipotence in the Abrahamic faiths have evolved over the millennia.
