Storage capacity is the amount of energy extracted from an energy storage device or system; usually measured in joules or kilowatt-hours and their multiples, it may be given in number of hours of electricity production at power plant nameplate capacity; when storage is of primary type (i.e., thermal or pumped-water), output is sourced only with ...
Energy democracy is a concept developed within the environmental justice movement that pairs the renewable energy transition with efforts to democratize the production and management of energy resources— including the social ownership of energy infrastructure, decentralization of energy systems, and expansion of public participation in energy-related policymaking.
Direct democracy or pure democracy is a form of democracy in which the electorate directly decides on policy initiatives, without elected representatives as proxies, as opposed to the representative democracy model which occurs in the majority of established democracies.
Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce carbon dioxide or other atmospheric pollutants and it provides a relatively ...
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.
Battery storage capacity is not expected to overtake pumped storage during the 2020s. [2] When used as peak power to meet demand, hydroelectricity has a higher value than baseload power and a much higher value compared to intermittent energy sources such as wind and solar.
The well-educated, former Presbyterian from Michigan fought hard for what he believed to be right, including direct democracy, education, labor rights, women’s suffrage, helping the poor and ...
A combination of design and construction flaws, continuing to operate the dam when the primary system for gauging the water level was known to be inaccurate (gauge pipes had become detached), moving the "failsafe" secondary gauging system above the actual height of the dam to avoid false positives, and operating the dam in an unsafe manner by ...
