In 2023, the US electric power sector produced 4017 billion kWh of electric power. Renewable sources – wind, solar, hydro, biomass, and geothermal – accounted for 22% of generation, or 874 billion kWh, last year. Annual renewable power generation surpassed nuclear generat...
Instead of fuel- powered engines (引擎), the X-Plane gets its power from batteries. The aircraft is also quieter than fuel-powered planes, as its electric components (部件)change the way it sounds. It has 14 electric motors (发动机)and propellers(螺旋桨), allowing it to fly more ...
electric powerlong memorypersistenceThis study analyzes energy consumption by the US electric power by various energy sources through fractional integration. In doing so, we are able to determine the level of persistence of the shocks affecting each energy source. The results indicate long memory ...
First, we will examine some of the new resources that are creating value in this variable operating environment. Then, we will identify barriers prohibiting the full realization of their potential. Finally, we will conclude with solutions that...

states and remove carbon from the electric sector by 2035. Some utilities are investing in gas with an eye to cleaner options. Entergy is proposing to build a power plant in Texas with equipment manufacturer Mitsubishi Power whose turbines will be able to burn a mix of gas and hydrogen. Paul...
It was found that emission of pollutants from the country's energy sector has been steadily declining, with annual emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) decreasing from the US electric power sector between 1990 and 2020 by 93.4% and 84.8%, respectively, and carbon ...
Portable generators are useful when temporary or remote electric power is needed, but they also can be hazardous. The primary hazards to avoid when using a generator are carbon monoxide (CO) poisoning from the toxic engine exhaust, electric shock or electrocution, and fire. ...
Federal energy regulators on Monday approved a long-awaited rule to make it easier to transmit renewable energy such as wind and solar power to the electric grid—a key part of President Joe Biden's goal to eliminate carbon ...
