Statistical Review of World Energy
Global primary energy consumption grew strongly in 2017, led by natural gas and renewables, with coal’s share of the energy mix continuing to decline
- Primary energy consumption growth averaged 2.2% in 2017, up from 1.2 % last year and the fastest since 2013. This compares with the 10-year average of 1.7% per year.
- By fuel, natural gas accounted for the largest increment in energy consumption, followed by renewables and then oil.
- Energy consumption rose by 3.1% in China. China was the largest growth market for energy for the 17th consecutive year.
- Carbon emissions increased by 1.6%, after little or no growth for the three years from 2014 to 2016.
Despite the Never-Ending Death of Coal: It’s Still a Fossil Fueled World

Black carbon refers to tiny carbon particles that form during incomplete combustion of carbon-based fuels. Black carbon particles absorb sunlight, so they are considered to contribute to global warming. However, the contribution of black carbon to the heating of the Earth’s atmosphere is currently uncertain. Models that can accurately assess the warming effect of black carbon on our atmosphere are needed so that we can understand the contribution of these tiny carbon particles to climate change. The mixing state of black carbon particles and their particle size strongly influence their ability to absorb sunlight, but current models have large uncertainties associated with both particle size and mixing state.

WUWT readers may recall that climate activists wanted the current epoch we live in to be named the “Anthropocene”, because they believe humans are the dominate force on the planet. The official organization that decides such things, The International Commission on Stratigraphy, would have none of it, and nixed the naming recently. Now, here’s a summary of the the Meghalayan.
Welcome to the new Meghalayan age – here’s how it fits with the rest of Earth’s geologic history

Jurassic, Pleistocene, Precambrian. The named times in Earth’s history might inspire mental images of dinosaurs, trilobites or other enigmatic animals unlike anything in our modern world.
