From the mid-1980s to September 2003, the inflation-adjusted price of a barrel of crude oil on NYMEX was generally under US$25/barrel in 2008 dollars. During 2003, the price rose above $30, reached $60 by 11 August 2005, and peaked at $147.30 in July 2008.

California produces more renewable energy than any other state in the United States except Texas. In 2018, California ranked first in the nation as a producer of electricity from solar, geothermal, and biomass resources and fourth in the nation in conventional hydroelectric power generation.

Aggreko is a global supplier of mobile and modular power, temperature control equipment and energy services, headquartered in Glasgow, United Kingdom. The business was founded in 1962 and previously listed on the London Stock Exchange from 1997 to 2021.

An energy crisis from 2021 to 2023 began in the aftermath of the COVID-19 pandemic, resulting in shortages and increased prices in oil, gas and electricity markets. The crisis was particularly acute in Europe, and especially following the Russian invasion of Ukraine, the energy crisis became popularly associated with…

Canada has access to all main sources of energy including oil and gas, coal, hydropower, biomass, solar, geothermal, wind, marine and nuclear. It is the world's second largest producer of uranium, third largest producer of hydro-electricity, fifth largest natural gas producer, and the fifth largest producer of crude…

Many countries and territories have installed significant solar power capacity into their electrical grids to supplement or provide an alternative to conventional energy sources. Solar power plants use one of two technologies: Photovoltaic (PV) systems use solar panels, either on rooftops or in ground-mounted solar…

The Inflation Reduction Act of 2022 (IRA), Pub. L. 117–169 (text) (PDF), is a United States federal law which aimed to reduce the federal government budget deficit, lower prescription drug prices, and invest in domestic energy production while promoting renewable energy.
