Wind Power Could Become Nation's Largest Source of Energy by 2050 With Deployment in All 50 States

Wind power could become even more prevalent in the U.S. than previously expected, according to a new report released last week from the Department of Energy (DOE), Enabling Wind Power Nationwide. The new report, which was announced at the American Wind Energy Association’s WINDPOWER Conference in Orlando, Florida, finds that there is wind power potential in nearly the entire U.S., even in places that were previously thought to have insufficient wind to generate electricity.

According to the report, the U.S. has the ability to "unlock the vast potential for wind energy deployment in all 50 states" because of next-generation wind turbines. These taller turbines with longer blades, which are currently under development by the DOE and its private industry partners will be able to capture the wind more effectively at higher altitudes where the wind is usually stronger and more constant, says the report.

There's potential to "unlock wind resources in regions with limited wind deployment today, such as the Southeast," says the report. "These new regions represent an additional 700,000 square miles—or about one-fifth of the U.S.—bringing the total area of technical wind potential to 1.8 million square miles."

The DOE has already helped the wind industry install nearly 66 gigawatts of wind power capacity—enough to power more than 17 million homes—and has helped decrease the cost of wind energy by more than 90 percent. Photo credit: DOE

Wind energy installation has skyrocketed in recent years. Wind and solar provided all of the new generating capacity in April, and, along with some geothermal and hydropower, these renewables provided 84 percent of the 1,900 MW of new U.S. electrical generating capacity placed into service during the first third of 2015.

"Wind generation has more than tripled in the United States in just six years, exceeding 4.5 percent of total generation, and we are focused on expanding its clean power potential to every state in the country," said Energy Secretary Ernest Moniz. "By producing the next generation of larger and more efficient wind turbines, we can create thousands of new jobs and reduce greenhouse gas emissions, as we fully unlock wind power as a critical national resource."

The DOE says these advanced wind energy systems "will generate more electricity per dollar invested and further drive down the cost of wind energy." Currently, wind energy produces less than 5 percent of all electricity, but by mid century, it could become the country's largest source of power, according to an earlier report from the DOE this spring. The report found that wind power could generate 35 percent of U.S. electricity by 2050.

Fire Seasons Have Become Longer Globally, Experts Say

Experts say that climate change is lengthening global fire seasons, as the southern hemisphere experiences "freak autumn heat" and major weekend bushfires devastate the Australian states of Victoria and New South Wales.

"March is not traditionally seen as a time when the bushfire danger escalates, but as the fires in Tartha NSW, and south west Victoria show, bushfires do not respect summer boundaries," said Richard Thornton, the CEO of the Bushfire and Natural Hazards Cooperative Research Centre.

A Tale of Two Cities: How San Francisco and Burlington Are Shaping America's Low-Carbon Future

By Kyra Appleby

President Trump's commitment to pull out of the Paris agreement signaled what appeared to be the worst of times for a transition to a low-carbon future in the United States. But actions being taken by a significant number of cities could instead make it the best of times for renewable energy in America.

Early April Fool's Joke? Statoil Rebrands Itself as Equinor

By Andy Rowell

First came BP, which went from British Petroleum to Beyond Petroleum. Then Denmark's Dong Energy changed its name to Orsted, to mark its departure from oil and gas. Then earlier this year Shell announced it was morphing from an oil company into an integrated energy company.

And now, the Norwegian company Statoil is proposing to change its name to "Equinor." The rebranding exercise—or what some may call greenwashing exercise—will cost as much as 250 million kroner or $32 million.

Risky Move: Canada Shipping More Tar Sands Oil by Rail

By Justin Mikulka

The Motley Fool has been advising investors on "How to Profit From the Re-Emergence of Canada's Crude-by-Rail Strategy." But what makes transporting Canadian crude oil by rail attractive to investors?

According to the Motley Fool, the reason is "… right now, there is so much excess oil being pumped out of Canada's oil sands that the pipelines simply don't have the capacity to handle it all."

At the height of the movement at Standing Rock, Indigenous teens half a world away in Norway were tattooing their young bodies with an image of a black snake. Derived from Lakota prophecy, the creature had come to represent the controversial Dakota Access pipeline for the thousands of water protectors determined to try to stop it.

Netflix’s 'Rotten' Reveals the Perils of Global Food Production

By Katherine Wei

We all love to eat. And increasingly, our cultural conversation centers around food—the cultivation of refined taste buds, the methods of concocting the most delectable blends of flavors, the ways in which it can influence our health and longevity, and the countless TV shows and books that are borne of people's foodie fascinations. However, there's one aspect we as consumers pay perhaps too little heed: the production of food before it reaches markets and grocery store shelves. We don't directly experience this aspect of food, and as a result, it's shrouded in mystery, and often, confusion.
