The wide expansion of coal, oil, and gas for heat and power generation left solar energy technology behind until oil price shocks initiated a development step in the 1980s, leading to the successful commercial start of the parabolic trough solar power plants SEGS I-IX in California until 1990.
In solar thermal systems, concentrators are used to extract the energy from solar irradiation and convert it into useful form. Among different types of solar concentrators, the parabolic dish solar concentrator is preferred as it has high efficiency, high power density, low maintenance, and potential for long durability.

Parabolic troughs are a type of solar thermal collector technology, primarily used to generate electricity in large-scale power plants. These collectors are uniquely designed to focus the sun''s energy on a singular point or line, thereby concentrating the heat and making the process of converting solar energy into electricity more efficient
A cleaner and environmentally-friendly form of cooking is solar cooking using the sun''s energy. Parabolic solar cookers perform better than other solar cookers such as box solar cookers since higher temperatures are achieved in a shorter duration. These higher temperatures allow most types of cooking processes such as; boiling, frying, roasting

A Solar Parabolic Dish is a type of Solar Collector that uses a parabolic reflector to focus sunlight onto a central receiver, where the solar energy is absorbed and converted into heat. It accomplishes this through the use of a computer and dual-axis tracking.
Dish/engine systems use a parabolic dish of mirrors to direct and concentrate sunlight onto a central engine that produces electricity. The dish/engine system is a concentrating solar power (CSP) technology that produces smaller amounts of electricity than other CSP technologies—typically in the range of 3 to 25 kilowatts—but is beneficial for modular use.
As of 2014, the largest solar thermal power systems using parabolic trough technology include the 354 MW SEGS plants in California, the 280 MW Solana Generating Station with molten salt heat storage, the 250 MW Genesis Solar Energy Project, the Spanish 200 MW Solaben Solar Power Station, and the Andasol 1 solar power station.
