Variable renewable energy (VRE) or intermittent renewable energy sources (IRES) are renewable energy sources that are not dispatchable due to their fluctuating nature, such as wind power and solar power, as opposed to controllable renewable energy sources, such as dammed hydroelectricity or bioenergy, or relatively constant sources, such as ...
An inverter-based resource (IBR) is a source of electricity that is asynchronously connected to the electrical grid via an electronic power converter ("inverter"). The devices in this category, also known as converter interfaced generation (CIG), include the variable renewable energy generators (wind, solar) and battery storage power stations. [1]
Renewable energy is also distinct from sustainable energy, a more abstract concept that seeks to group energy sources based on their overall permanent impact on future generations of humans. For example, biomass is often associated with unsustainable deforestation .
Energy portal; These are modes of energy production, energy storage, or energy conservation, listed alphabetically. Note that not all sources are accepted as legitimate or have been proven to be tappable. Bus running on soybean biodiesel.

China produced 31% of global renewable electricity, followed by the United States (11%), Brazil (6.4%), Canada (5.4%) and India (3.9%). [1] Renewable investment reached almost $500 billion globally in 2022, [2] amounting to 83% of new electric capacity that year. [3] The renewable energy industry employs almost 14 million people. [4]
Federal investigators found nearly a dozen children to be working dangerous, overnight shifts at Seaboard Triumph Foods' pork processing plant in Sioux City, Iowa, the Department of Labor announced.
An energy transition is a broad shift in technologies and behaviours that are needed to replace one source of energy with another. [14]: 202–203 A prime example is the change from a pre-industrial system relying on traditional biomass, wind, water and muscle power to an industrial system characterized by pervasive mechanization, steam power and the use of coal.
Americans are obsessed with a white Christmas and all the trimmings – snow, icicles, sleigh rides, frost on windowpanes, cuddling up by the fire, mittens, the North Pole. Christmas is a ...
