Energy statistics refers to collecting, compiling, analyzing and disseminating data on commodities such as coal, crude oil, natural gas, electricity, or renewable energy sources (biomass, geothermal, wind or solar energy), when they are used for the energy they contain. Energy is the capability of some substances, resulting from their physico-chemical properties, to do work or produce heat. Some energy commodities, called fuels, release their energy content as heat when they burn. This heat could be used to run an internal or external combustion engine.
The need to have statistics on energy commodities became obvious during the 1973 oil crisis that brought tenfold increase in petroleum prices. Before the crisis, to have accurate data on global energy supply and demand was not deemed critical. Another concern of energy statistics today is a huge gap in energy use between developed and developing countries. As the gap narrows (see picture), the pressure on energy supply increases tremendously.

The data on energy and electricity come from three principal sources:
The flows of and trade in energy commodities are measured both in physical units (e.g., metric tons), and, when energy balances are calculated, in energy units (e.g., terajoules or tons of oil equivalent). What makes energy statistics specific and different from other fields of economic statistics is the fact that energy commodities undergo greater number of transformations (flows) than other commodities. In these transformations energy is conserved, as defined by and within the limitations of the first and second laws of thermodynamics.
The economy of Canada is a highly developed mixed economy. It is the 9th-largest GDP by nominal and 15th-largest GDP by PPP in the world. As with other developed nations, the country's economy is dominated by the service industry which employs about three quarters of Canadians. It has the world's third-largest proven oil reserves and is the fourth-largest exporter of crude oil. It is also the fifth-largest exporter of natural gas.
Renewable energy is energy from renewable resources that are naturally replenished on a human timescale. Renewable resources include 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 is often used for electricity generation, heating and cooling. Renewable energy projects are typically large-scale, but they are also suited to rural and remote areas and developing countries, where energy is often crucial in human development. Renewable energy is often deployed together with further electrification, which has several benefits: electricity can move heat or objects efficiently, and is clean at the point of consumption.
The economy of Fiji is one of the most developed among the Pacific islands. Nevertheless, Fiji is a developing country endowed with forest, mineral and fish resources. The country has a large agriculture sector heavily based on subsistence agriculture. Sugar exports and the tourism industry are the main sources of foreign exchange. There are also light manufacturing and mining sectors.
An energy crisis or energy shortage is any significant bottleneck in the supply of energy resources to an economy. In literature, it often refers to one of the energy sources used at a certain time and place, in particular, those that supply national electricity grids or those used as fuel in industrial development. Population growth has led to a surge in the global demand for energy in recent years. In the 2000s, this new demand – together with Middle East tension, the falling value of the US dollar, dwindling oil reserves, concerns over peak oil, and oil price speculation – triggered the 2000s energy crisis, which saw the price of oil reach an all-time high of $147.30 per barrel ($926/m3) in 2008.
Energy development is the field of activities focused on obtaining sources of energy from natural resources. These activities include production of renewable, nuclear, and fossil fuel derived sources of energy, and for the recovery and reuse of energy that would otherwise be wasted. Energy conservation and efficiency measures reduce the demand for energy development, and can have benefits to society with improvements to environmental issues.
Electrification is the process of powering by electricity and, in many contexts, the introduction of such power by changing over from an earlier power source.
Energy is sustainable if it "meets the needs of the present without compromising the ability of future generations to meet their own needs." Most definitions of sustainable energy include considerations of environmental aspects such as greenhouse gas emissions and social and economic aspects such as energy poverty. Renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy are generally far more sustainable than fossil fuel sources. However, some renewable energy projects, such as the clearing of forests to produce biofuels, can cause severe environmental damage.
The following outline is provided as an overview of and topical guide to energy:
The energy industry is the totality of all of the industries involved in the production and sale of energy, including fuel extraction, manufacturing, refining and distribution. Modern society consumes large amounts of fuel, and the energy industry is a crucial part of the infrastructure and maintenance of society in almost all countries.
The energy policy of the United States is determined by federal, state, and local entities. It addresses issues of energy production, distribution, consumption, and modes of use, such as building codes, mileage standards, and commuting policies. Energy policy may be addressed via include legislation, regulation, court decisions, public participation, and other techniques.
Energy in the United Kingdom came mostly from fossil fuels in 2021. Total energy consumption in the United Kingdom was 142.0milliontonnes of oil equivalent in 2019. In 2014, the UK had an energy consumption per capita of 2.78tonnes of oil equivalent compared to a world average of 1.92tonnes of oil equivalent. Demand for electricity in 2014 was 34.42GW on average coming from a total electricity generation of 335.0TWh.
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, fourth largest natural gas producer, and the fifth largest producer of crude oil. In 2006, only Russia, the People's Republic of China, the United States and Saudi Arabia produce more total energy than Canada.
Ensuring adequate energy supply to sustain economic growth has been a core concern of the Chinese government since 1949. The country is the world's largest emitter of greenhouse gases, and coal in China is a major cause of global warming. However, from 2010 to 2015 China reduced energy consumption per unit of GDP by 18%, and CO2 emissions per unit of GDP by 20%. On a per-capita basis, it was the world's 51st largest emitter of greenhouse gases in 2016. China is also the world's largest renewable energy producer. China is the largest producer of hydroelectricity, solar power and wind power in the world. The energy policy of China is connected to its industrial policy. The goals of China's industrial policy dictate its energy needs.
Renewable energy in Finland grew to 38.7% of total final energy consumption by year end 2014, achieving joint second position with Latvia in terms of renewable energy consumption by share amongst the EU-28 countries, behind its neighbour Sweden in first position on a 52.6% share. The 2014 share in Finland breaks down as renewable energy providing 52% of the heating and cooling sector, 31.4% of the electricity sector and 21.6% of the transport sector. By 2014, Finland had already exceeded its 2020 target for renewable energy use under the EU renewable energy directive as shown in the table of country targets.
Vietnam is a dynamic developing economy with a relatively high growth rate. The energy sector plays a key role in promoting the country's socio-economic development. Vietnam has a diverse energy fuel resource of various types such as coal, natural gas, petroleum, hydropower and renewables such as solar and wind energy. The country has recently been successful in renewable energy deployment, especially solar and wind power development. Coal has been the key power generation source since 2018. Coal accounted for about 30% of installed capacity and 47% of electricity generation in 2021 The high use of coal makes Vietnam an increasingly important emitter of carbon dioxide, contributing to climate change.
Energy market is a type of commodity market that deal with electricity, heat, and fuel products. Major commodities being natural gas and electricity. Other commodities traded in the energy market are: oil, coal, carbon emissions, nuclear power, solar energy, and wind energy. Due to the difficulty in storing and transporting energy, current and future prices in energy are rarely linked. This is because energy purchased at current prices is difficult to store and sell at a later date. There are two types of markets namely spot market and forward market.
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.
Renewable energy has developed rapidly in Italy over the past decade and provided the country a means of diversifying from its historical dependency on imported fuels. Solar power accounted for around 8% of the total electric production in the country in 2014, making Italy the country with the highest contribution from solar energy in the world that year. Rapid growth in the deployment of solar, wind and bio energy in recent years lead to Italy producing over 40% of its electricity from renewable sources in 2014.
World energy supply and consumption is global production and preparation of fuel, generation of electricity, energy transport, and energy consumption. It is a basic part of economic activity. It includes heat, but not energy from food.
The 2020s commodities boom refers to the rise of many commodity prices in the early 2020s following the COVID-19 pandemic. The COVID-19 recession initially made commodity prices drop, but lockdowns, supply chain bottlenecks, and dovish monetary policy limited supply and created excess demand causing a commodity super cycle rise.
