The total solar irradiance is measured by satellite to be roughly 1361 watts per square meter (see solar constant), though it fluctuates by about 6.9% during the year due to the Earth's varying distance from the sun. Despite a near-record drop in power demand due to the pandemic, renewables accounted for 1,129 terawatt-hours in January-June, compared with 992 in the first six months of 2019, according to a report by the Ember energy think tank. Popular gadgets including laptop, tablet and mobile specifications, features, prices, comparison. In 2008, total worldwide primary energy consumption was 132,000 terawatt-hours (TWh) or 474 exajoules (EJ).  In 2019 it made up 6.5% of total energy use. , The European Environmental Agency (EEA) measures final energy consumption (does not include energy used in production and lost in transportation) and finds that the transport sector is responsible for 32% of final energy consumption, households 26%, industry 26%, services 14% and agriculture 3% in 2012.  Biomass combustion is a major contributor. Around 10% of the world’s total electricity consumption is being used by the internet, according to a recent research report from Swedish KTH.  From 1965 to 2008, the use of fossil fuels has continued to grow and their share of the energy supply has increased.  According to that same impact assessment by the European Commission, raising the efficiency of all new plants and the majority of existing plants, through the setting of authorisation and permit conditions, to an average generation efficiency of 52% in 2020 would lead to a reduction in annual consumption of 15 km3 (3.6 cu mi) of natural gas and 25 Mt (25,000,000 long tons; 28,000,000 short tons) of coal. , Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. 07. This evolution is the result of two contrasting trends: Energy consumption growth remained vigorous in several developing countries, specifically in Asia (+4%). According to IEA data from 1990 to 2008, the average energy use per person increased 10% while world population increased 27%. At a global level, the percentage of people with access to electricity has been steadily increasing over the last few decades. For instance, when oil is extracted from the ground it must be refined into gasoline, so that it can be used in a car, and transported over long distances to gas stations where it can be used … This was despite leading emitter China increasing its share of the global coal fleet slightly. Most energy is used in the country of origin, since it is cheaper to transport final products than raw materials. China became the world's largest energy consumer (18% of the total) since its consumption surged by 8% during 2009 (up from 4% in 2008). in Australia, Japan, or Canada, more energy is used per capita than in Bangladesh or Burma. The numbers have grown from 8% in 2012, illustrating the increasing effects of the internet’s rapid growth. Access to electricity (% of population) Definition: Access to electricity is the percentage of population with access to electricity. Source: US DOE.  Technological developments in the 1990s have allowed efficiencies in the range of 40–45% at newer plants. Color of the countries with the highest data: blue.  In 2019 wind made up 2.2% of total energy use. Britain and the European Union were singled out for particular praise, deriving 21 and 33 percent of their power from renewables, respectively.  Hydropower is produced in 150 countries, with the Asia-Pacific region generating 32 percent of global hydropower in 2010. Who is responsible for fighting smartphone addiction? "A large part of this is obviously due to the pandemic rather than long term trends and ― let's be honest ― it's not fast enough if your target is 1.5 C," he said. Meanwhile, Japan (3% of global emissions) reduced its energy-related CO2 emissions by 2.1%, the United States (13% of total emissions) by 2.6% and Russia (5% of total emissions) by 0.8%.  Indonesia and Australia exported together 57.1% of the world coal export in 2011. Copyright © 2020. 44-45), in. We believe that information should be free and will therefore never put up a paywall. Heat, especially at a relatively low temperature, is low-quality energy, whereas electricity is high-quality energy. Best-case scenario sees a growth from 1 982 TWh (terawatt hours) per year, expected scenarios sees it go up to 2 547 TWh per year and worst-case scenario sees numbers go up by 3 422 TWh a year. The International Energy Agency projected that solar power could provide "a third of the global final energy demand after 2060, while CO2 emissions would be reduced to very low levels. Oil remained the largest energy source (33%) despite the fact that its share has been decreasing over time.  Heat pumps are small and widely distributed, so estimates of their total capacity are uncertain and range up to 100 GW.. The map shows the indicator: Access to electricity (% of population). From 2003 to 2008, coal was the fastest growing fossil fuel. World total primary energy supply (TPES), or "primary energy" differs from the world final energy consumption because much of the energy that is acquired by humans is lost as other forms of energy during the process of its refinement into usable forms of energy and its transport from its initial place of supply to consumers. Coal and natural gas were the most used energy fuels for generating electricity. "Thirty percent of fossil fuel emissions globally are just from coal power plants, so coal fired power generation needs to collapse quickly in order to limit climate change," said Jones. This figure is about 18% smaller than the generated electricity, due to grid losses, storage losses, and self-consumption from power plants (gross generation).  Most of the other 82% was used for heat and transportation. Source of the map : Get technology news, gadgets reviews & ratings. Its population of 1.3 billion people (19.6% of the world population) is consuming energy at a rate of 1.6 kW per person. Others: Mathematically calculated, includes e.g. 2020 Telenor in a Battle Against Cyberbullying. Color of the map for the indicator: Access to electricity (% of population). By the end of 2014, the total installed electricity generating capacity worldwide was nearly 6.14 TW (million MW) which only includes generation connected to local electricity grids. , As of 1 July 2016, the world had 444 operable grid-electric nuclear fission power reactors with 62 others under construction. Improved data and understanding of world energy consumption may reveal systemic trends and patterns, which could help frame current energy issues and encourage movement towards collectively useful solutions. For instance, when oil is extracted from the ground it must be refined into gasoline, so that it can be used in a car, and transported over long distances to gas stations where it can be used by consumers.  Across 40 years, this averages to a 2% decrease every year. 9,723 TWh (836 Mtoe) in 2015. Coal production was in 2011 7,783 Mt, and 2009 6,903 Mt, equal to 12.7% production increase in two years. It was stable in India (slowdown in industrial consumption) and in Russia (milder temperatures). Fossil fuels are dominant in the global energy mix, supported by $523 billion subsidies in 2011, up almost 30% on 2010 and six times more than subsidies to renewables..
