Plans Unveiled for World's Largest, Most Powerful Offshore Wind Turbine
Each 12-megawatt Haliade-X stands 853 feet tall, or roughly five times the height of the Arc de Triomphe in Paris, and features 350-foot blades, or the length of a Major League Soccer field.
One turbine can generate 67 gigawatt-hours annually, or enough clean energy for up to 16,000 households. A 750-megawatt wind farm configuration could power 1 million households. GE says the Haliade-X will produce 45 percent more energy than any other offshore wind turbine available today.

"We want to lead in the technologies that are driving the global energy transition," General Electric CEO John Flannery said.
Companies are making bigger and bigger offshore turbines that can capture more wind and produce more power. This is appealing for wind farm developers because fewer turbines can simplify operations and lower maintenance costs.
Greentech Media pointed out that GE is "playing catchup" with its competitors. Its current 6-megawatt offshore turbines, which are installed at the Block Island Wind Farm off Rhode Island, lags behind the ones made by MHI Vestas and Siemens Gamesa Renewable Energy.
GE estimates the new turbine will achieve a 63 percent capacity factor, which is five to seven points more than the industry benchmark, noting that each percentage point in capacity factor is worth around $7 million.
More than $400 million will be invested over the next three to five years to develop the Haliade-X. The company aims to supply its first nacelle, or power generating unit, for demonstration in 2019 and ship the first units in 2021.
"The renewables industry took more than 20 years to install the first 17 GW of offshore wind. Today, the industry forecasts that it will install more than 90 GW over the next 12 years," said Jérôme Pécresse, president and CEO of GE Renewable Energy. "This is being driven by lower cost of electricity from scale and technology. The Haliade-X shows GE's commitment to the offshore wind segment and will set a new benchmark for cost of electricity, thus driving more offshore growth."

Plastic pollution in the world's oceans has become a global environmental crisis. Many people have seen images that seem to capture it, such as beaches carpeted with plastic trash or a seahorse gripping a cotton swab with its tail.
Greenland is melting about four times faster than it was in 2003, a new study published Monday in the Proceedings of the National Academy of Sciences found, a discovery with frightening implications for the pace and extent of future sea level rise.
"We're going to see faster and faster sea level rise for the foreseeable future," study lead author and Ohio State University geodynamics professor Dr. Michael Bevis said in a press release. "Once you hit that tipping point, the only question is: How severe does it get?"
Finally, some good news about the otherwise terrible partial government shutdown. A federal judge ruled that the Trump administration cannot issue permits to conduct seismic testing during the government impasse.
The Justice Department sought to delay—or stay—a motion filed by a range of coastal cities, businesses and conservation organizations that are suing the Trump administration over offshore oil drilling, Reuters reported. The department argued that it did not have the resources it needed to work on the case due to the shutdown.
Most people have heard of the Amazon, South America's famed rainforest and hub of biological diversity. Less well known, though no less critical, is the Pantanal, the world's largest tropical wetland.
Like the Amazon, the Pantanal is ecologically important and imperiled. Located primarily in Brazil, it also stretches into neighboring Bolivia and Paraguay. Covering an area larger than England at more than 70,000 square miles, the massive wetland provides irreplaceable ecosystem services that include the regulation of floodwaters, nutrient renewal, river flow for navigability, groundwater recharge and carbon sequestration. The wetland also supports the economies of the four South American states it covers.

Organizers said 35,000 people marched through the streets of the German capital on Saturday to say they're "fed up" with industrial agriculture and call for a transformation to a system that instead supports the welfare of the environment, animals and rural farmers.

If you have ever considered making the switch to an environmentally friendly electric vehicle, don't drag your feet. Though EV prices are falling, and states are unveiling more and more public charging stations and plug-in-ready parking spots, the federal government is doing everything it can to slam the brakes on our progress away from gas-burning internal combustion engines. President Trump, likely pressured by his allies in the fossil fuel industry, has threatened to end the federal tax credits that have already helped put hundreds of thousands of EVs on the road—a move bound to harm not only our environment but our economy, too. After all, the manufacturing and sale of EVs, hybrids, and plug-in hybrids supported 197,000 jobs in 2017, according to the most recent U.S. Energy and Employment Report.

Formidable predators stalk the forests between Panama and northern Argentina. They are sometimes heard but never seen. They are small but feisty and have even been documented trying to take down a tapir, which can top out at nearly 400 pounds. Chupacabras? No.
