This notion of “energy-efficient prosperity” is especially relevant for developing countries, which can most benefit from investing in energy efficiency improvements that provide affordable and reliable services, while supporting a strong economy and improved quality of life over the long term
As this series will show, energy efficiency policies are available to all, from factories in the Balkans to households in South Africa. Many can benefit from simple investments that can deliver more services for the same amount of energy input, or the same services for even less energy input. In fact, governments are looking at energy efficiency as the “first fuel” – a source of energy in its own right, in which they can invest ahead of other more complex or costly energy sources
The International Energy Agency in its latest report, Energy Efficiency Market Report 2016, found that last year consumers, businesses and governments spent USD 221 billion on energy efficiency improvements in 2015
Between now and 2035, more than 95% of the projected growth in global energy demand will happen in developing countries, especially in China, India and Southeast Asia. And while sustained economic growth is likely to lead to higher levels of energy use overall, there is clear potential for countries to use energy more efficiently
One example among many is a furniture factory in the Balkans where workers used to start their days by loading wood briquettes into a furnace. Like many manufacturing companies in post-Communist Balkan countries, its operations relied on old, inefficient equipment and incurred high energy costs
World coal consumption fell by 0.6% (-0.9 EJ), its fourth decline in six years, displaced by natural gas and renewables, particularly in the power sector (see electricity section). As a result, coal’s share in the energy mix fell to 27.0%, its lowest level in 16 years
Coal consumption continued to increase in some emerging economies, particularly in China (1.8 EJ), Indonesia (0.6 EJ) and Vietnam (0.5 EJ), with the latter posting a record increase in part related to a sharp drop in hydroelectric power. Growth in India, usually a key driver of coal consumption, was only 0.3% (0.1 EJ) – its lowest since 2001. These increases in coal consumption were more than offset by falls in demand in the developed world, led by the US (-1.9 EJ) and Germany (-0.6 EJ), with OECD coal consumption falling to its lowest level in our data series (which goes back to 1965).
Global coal production rose by 1.5%, with China and Indonesia providing the only significant increases (3.2 EJ and 1.3 EJ respectively). As with consumption, the largest declines in production came from the US (-1.1 EJ) and Germany (-0.3 EJ).
World coal reserves in 2019 stood at 1070 billion tonnes and are heavily concentrated in just a few countries: US (23%), Russia (15%), Australia (14%) and China (13%). Most of the reserves are anthracite and bituminous (70%). The current global R/P ratio shows that coal reserves in 2019 accounted for 132 years of current production with North America (367 years) and CIS (338 years) the regions with the highest ratios.
Coal trade decreased by 1.3%, the first decline since 2015. Notable declines in exports came from the US (-0.5 EJ), Australia (-0.4 EJ) and Colombia (-0.3 EJ) with strong growth in exports seen only in Indonesia (0.6 EJ). On the import side, falling imports in Europe (-1.2 EJ) and Japan & South Korea (-0.3 EJ combined) outweighed growth in the rest of Asia (1.3 EJ).
