Cyathus is a genus of fungi in the family Nidulariaceae. Along with the genera Crucibulum, Mycocalia, Nidula and Nidularia, they are known collectively as the bird's nest fungi due to their small nest-like fruiting bodies containing egg-shaped peridioles. The genus Cyathus was monographed by mycologist Lloyd (1906), and later Brodie (1975, 1984), and their species concepts, especially those of Brodie (1975), are followed by most mycologists.

This is a list of Columbiformes species by global population. While numbers are estimates, they have been made by the experts in their fields. For more information on how these estimates were ascertained, see Wikipedia's articles on population biology and population ecology.

Most of the world's largest oilfields are located in the Middle East, but there are also supergiant (>10 billion bbls) oilfields in India, Brazil, Mexico, Venezuela, Kazakhstan, and Russia. Amounts listed below, in billions of barrels, are the estimated ultimate recoverable petroleum resources (proved reserves plus cumulative production), given historical production and current extraction technology. Oil shale reserves (perhaps 3 trillion barrels (4.8×1011 m3)) and Coal reserves, both of which can be converted to liquid petroleum, are not included in this chart.

This is a list of solar thermal power stations. These include the 354 megawatt (MW) Solar Energy Generating Systems power installation in the USA, Solana Generating Station (USA, 280 MW) and Solaben Solar Power Station (Spain, 200 MW). The 392 MW Ivanpah Solar Power Facility, located in California's Mojave Desert, is the world’s largest solar thermal power plant project currently in operation.

The Three Gorges Dam in Hubei, China, has the world's largest instantaneous generating capacity (22,500 MW), with the Itaipu Dam in Brazil/Paraguay in second place (14,000 MW).
