Renewable energy is energy that is collected from renewable resources that are naturally replenished on a human timescale. It includes sources such as sunlight, wind, the movement of water, and geothermal heat. Although most renewable energy sources are sustainable, some are not. For example, some biomass sources are considered unsustainable at current rates of exploitation. Renewable energy often provides energy for electricity generation to a grid, air and water heating/cooling, and stand-alone power systems. About 20% of humans' global energy consumption is renewables, including almost 30% of electricity. About 7% of energy consumption is traditional biomass, but this is declining. Over 4% of energy consumption is heat energy from modern renewables, such as solar water heating, and over 6% electricity.
Geothermal energy is the thermal energy in the Earth's crust which originates from the formation of the planet and from radioactive decay of materials in currently uncertain but possibly roughly equal proportions. The high temperature and pressure in Earth's interior cause some rock to melt and solid mantle to behave plastically. This results in parts of the mantle convecting upward since it is lighter than the surrounding rock. Temperatures at the core–mantle boundary can reach over 4000 °C (7200 °F).
Canned Heat is an American blues rock band that was formed in Los Angeles in 1965. The group has been noted for its efforts to promote interest in blues music and its original artists. It was launched by two blues enthusiasts Alan Wilson and Bob Hite, who took the name from Tommy Johnson's 1928 "Canned Heat Blues", a song about an alcoholic who had desperately turned to drinking Sterno, generically called "canned heat", from the original 1914 product name Sterno Canned Heat. After appearances at the Monterey and Woodstock festivals at the end of the 1960s, the band acquired worldwide fame with a lineup consisting of Hite (vocals), Wilson, Henry Vestine and later Harvey Mandel, Larry Taylor (bass), and Adolfo de la Parra (drums).
A heat wave, or heatwave, is a period of excessively hot weather, which may be accompanied by high humidity, especially in oceanic climate countries. While definitions vary, a heat wave is usually measured relative to the usual weather in the area and relative to normal temperatures for the season. Temperatures that people from a hotter climate consider normal can be called a heat wave in a cooler area if they are outside the normal climate pattern for that area.
The 2003 European heat wave saw the hottest summer recorded in Europe since at least 1540. France was hit especially hard. The heat wave led to health crises in several countries and combined with drought to create a crop shortfall in parts of Southern Europe. The death toll has been estimated at more than 70,000.
The Reverend Horton Heat is the stage name of American musician James C. Heath as well as the name of his Dallas, Texas-based psychobilly trio. Heath is a singer, songwriter and guitarist. A Prick magazine reviewer called Heath the "godfather of modern rockabilly and psychobilly".
Cogeneration or combined heat and power (CHP) is the use of a heat engine or power station to generate electricity and useful heat at the same time.
District heating is a system for distributing heat generated in a centralized location through a system of insulated pipes for residential and commercial heating requirements such as space heating and water heating. The heat is often obtained from a cogeneration plant burning fossil fuels or biomass, but heat-only boiler stations, geothermal heating, heat pumps and central solar heating are also used, as well as heat waste from factories and nuclear power electricity generation. District heating plants can provide higher efficiencies and better pollution control than localized boilers. According to some research, district heating with combined heat and power (CHPDH) is the cheapest method of cutting carbon emissions, and has one of the lowest carbon footprints of all fossil generation plants.
Contemporary climate change includes both global warming and its impacts on Earth's weather patterns. There have been previous periods of climate change, but the current changes are distinctly more rapid and not due to natural causes. Instead, they are caused by the emission of greenhouse gases, mostly carbon dioxide and methane. Burning fossil fuels for energy production creates most of these emissions. Certain agricultural practices, industrial processes, and forest loss are additional sources. Greenhouse gases are transparent to sunlight, allowing it through to heat the Earth's surface. When the Earth emits that heat as infrared radiation the gases absorb it, trapping the heat near the Earth's surface and causing global warming.
The potential for exploiting geothermal energy in the United Kingdom on a commercial basis was initially examined by the Department of Energy in the wake of the 1973 oil crisis. Several regions of the country were identified, but interest in developing them was lost as petroleum prices fell. Although the UK is not actively volcanic, a large heat resource is potentially available via shallow geothermal ground source heat pumps, shallow aquifers and deep saline aquifers in the mesozoic basins of the UK. Geothermal energy is plentiful beneath the UK, although it is not readily accessible currently except in specific locations.
Geothermal power is electrical power generated from geothermal energy. Technologies in use include dry steam power stations, flash steam power stations and binary cycle power stations. Geothermal electricity generation is currently used in 26 countries, while geothermal heating is in use in 70 countries.
Energy in Finland describes energy and electricity production, consumption and import in Finland. Energy policy of Finland describes the politics of Finland related to energy. Electricity sector in Finland is the main article of electricity in Finland.
Sweden participated in the Eurovision Song Contest 2010 with the song "This Is My Life" written by Bobby Ljunggren and Kristian Lagerström. The song was performed by Anna Bergendahl. The Swedish broadcaster Sveriges Television (SVT) organised the national final Melodifestivalen 2010 in order to select the Swedish entry for the 2010 contest in Oslo, Norway. After a six-week-long competition consisting of four heats, a Second Chance round and a final, "This Is My Life" performed by Anna Bergendahl emerged as the winner after achieving the highest score following the combination of votes from six international jury groups, five regional jury groups and a public vote.
The Heroes of Woodstock Tour was a North American concert tour celebrating the 40th anniversary of the 1969 Woodstock Festival. The tour featured several bands, most of which performed at the original Woodstock festival or feature members that performed at the festival. The musicians featured differed slightly from venue to venue but most of the concerts featured Jefferson Starship, Big Brother and the Holding Company, Canned Heat, Ten Years After and Tom Constanten. Some dates featured Melanie, Edgar Winter, John Sebastian, Quicksilver Messenger Service, Mountain and the Levon Helm Band. Country Joe McDonald hosted all of the concerts, playing a couple of songs in between the different sets.
The 2010 Northern Hemisphere summer heat waves included severe heat waves that impacted most of the United States, Kazakhstan, Mongolia, China, Hong Kong, North Africa and the European continent as a whole, along with parts of Canada, Russia, Indochina, South Korea and Japan during May, June, July, and August 2010. The first phase of the global heatwaves was caused by a moderate El Niño event, which lasted from June 2009 to May 2010. The first phase lasted only from April 2010 to June 2010, and caused only moderate above average temperatures in the areas affected. But it also set new record high temperatures for most of the area affected, in the Northern Hemisphere. The second phase was caused by a very strong La Niña event, which lasted from June 2010 to June 2011. According to meteorologists, the 2010–11 La Niña event was one of the strongest La Niña events ever observed. That same La Niña event also had devastating effects in the Eastern states of Australia. The second phase lasted from June 2010 to October 2010, caused severe heat waves, and multiple record-breaking temperatures. The heatwaves began in April 2010, when strong anticyclones began to develop, over most of the affected regions, in the Northern Hemisphere. The heatwaves ended in October 2010, when the powerful anticyclones over most of the affected areas dissipated.
