Energy Corporation Says Up to 30 Percent of Its Wind Turbines Could Be Malfunctioning

Admin

Siemens Energy announced Thursday that it will be undergoing a technical review after it was found that up to 30% of its wind turbines could have faulty components, according to statements made by the company.

Siemens Energy, an international energy company that seeks to “decarbonize global energy systems,” announced that it is withdrawing its profit guidance for the year after subsidiary Siemens Gamesa found that there was a “substantial increase in failure rates of wind turbine components.” The company believes that between 15% and 30% of its installed fleets are suffering from component failures, Jochen Eickholt, CEO of Siemens Gamesa, said during a Friday morning analyst call.

Commentary: More Mining at Home Is a Win-Win for Environment and Defense

RealClearWire

This week, the U.S. Senate Energy Committee is examining the feasibility of building domestic supply chains for crucial minerals. The U.S. is currently completely dependent on imports of rare earth elements (REEs) that will determine whether the Biden Administration’s environmental and electrification goals are met. REEs also are used in essential defense systems like fighter jet engines, missile guidance and defense systems, and secure communication networks. Regardless if you are a champion of environmental protection or a strong national defense, bringing crucial supply chains to the U.S. will result in less emissions, higher environmental standards, and more control over materials that are the key to a greener and more secure future.

Green technology that underpins solar panels, wind turbines, and the lithium-ion batteries that store energy all require REEs. Neodymium, cobalt, copper, and lithium are all used in electrical vehicles, and those minerals are just a few of the 17 key minerals that the U.S. is completely dependent on imports for, and they’re a fraction of 29 other minerals that the U.S. imports half its domestic needs.

Tennessee Valley Authority’s Use of Diverse Power Generation Sources Credited With Keeping Electricity Flowing in Tennessee During Winter Storms

Jason M. Reynolds

Unlike Texas, Tennessee has been blessed to largely keep the electricity on during the winter storms, with Tennessee Valley Authority (TVA) crediting its diverse generation assets.

Although thousands of homes throughout the Tennessee Valley have lost power at different times thanks to issues like trees falling on transmission lines, electric generation in the Volunteer State has held up despite the high demands from below-freezing temperatures.

Solar And Wind Produced Just Three Percent of Global Energy

Admin

by Michael Bastasch   Wind and solar energy generation is growing, but it’s still an incredibly small part of the global energy mix, according to statistics compiled by the oil giant BP. Meanwhile, fossil fuels — coal, natural gas and oil — accounted for 85% of global energy consumption in 2018, BP reported Tuesday as part of its annual energy report. In fact, BP reported the U.S. led the world in oil and natural gas production growth. U.S. petroleum output saw the biggest annual growth ever recorded in any country, BP said. In other words, shale is booming. The U.S. surpassed Saudi Arabia and Russia in 2018 to become the world’s largest oil-producing nation. “Oil remains the most used fuel in the energy mix,” BP reported in its annual energy review. “Coal is the second largest fuel but lost share in 2018 to account for 27%, its lowest level in 15 years. The share of natural gas increased to 24%, such that the gap between coal and gas has narrowed to three percentage points.” “The contribution of hydro and nuclear remained relatively flat in 2018 at 7% and 4%, respectively,” BP reported. “Strong growth pushed up renewables share to 4%,…
