Electricity generationElectricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry, it is the stage prior to its delivery (transmission, distribution, etc.) to end users or its storage (using, for example, the pumped-storage method). Usable electricity is not freely available in nature, so it must be "produced" (that is, transforming other forms of energy to electricity). Production is carried out in power stations (also called "power plants").
Ocean thermal energy conversionOcean Thermal Energy Conversion (OTEC) uses the ocean thermal gradient between cooler deep and warmer shallow or surface seawaters to run a heat engine and produce useful work, usually in the form of electricity. OTEC can operate with a very high capacity factor and so can operate in base load mode. The denser cold water masses, formed by ocean surface water interaction with cold atmosphere in quite specific areas of the North Atlantic and the Southern Ocean, sink into the deep sea basins and spread in entire deep ocean by the thermohaline circulation.
Diesel cycleThe Diesel cycle is a combustion process of a reciprocating internal combustion engine. In it, fuel is ignited by heat generated during the compression of air in the combustion chamber, into which fuel is then injected. This is in contrast to igniting the fuel-air mixture with a spark plug as in the Otto cycle (four-stroke/petrol) engine. Diesel engines are used in aircraft, automobiles, power generation, diesel–electric locomotives, and both surface ships and submarines.
Guaranteed minimum incomeGuaranteed minimum income (GMI), also called minimum income (or mincome for short), is a social-welfare system that guarantees all citizens or families an income sufficient to live on, provided that certain eligibility conditions are met, typically: citizenship; a means test; and either availability to participate in the labor market, or willingness to perform community services. The primary goal of a guaranteed minimum income is reduction of poverty. In circumstances when citizenship is the sole qualification, the program becomes a universal basic income system.
SasolSasol Limited is an integrated energy and chemical company based in Sandton, South Africa. The company was formed in 1950 in Sasolburg, South Africa, and built on processes that German chemists and engineers first developed in the early 1900s (see coal liquefaction). Today, Sasol develops and commercializes technologies, including synthetic fuel technologies, and produces different liquid fuels, chemicals, coal tar, and electricity. Sasol is listed on the Johannesburg Stock Exchange (JSE: SOL) and the New York Stock Exchange (NYSE: SSL).
