Fossil fuel divestment or fossil fuel divestment and investment in climate solutions is an attempt to reduce climate change by exerting social, political, and economic pressure for the institutional divestment of assets including stocks, bonds, and other financial instruments connected to companies involved in extracting fossil fuels.
Carbon-based fuel is any fuel principally from the oxidation or burning of carbon.Carbon-based fuels are of two main kinds, biofuels and fossil fuels.Whereas biofuels are derived from recent-growth organic matter [1] and are typically harvested, as with logging of forests and cutting of corn, fossil fuels are of prehistoric origin [2] and are extracted from the ground, the principal fossil ...
NEED works with educators and students to improve existing materials and develop new ones to meet national and state curriculum requirements. In a special partnership with the Energy Information Administration, NEED helps make energy information and data available to students via the EIA Kids' Page website. In 2006, the Kid's Page was one of ...
Fossil fuels are hydrocarbons, primarily coal and petroleum (liquid petroleum or natural gas), formed from the fossilized remains of ancient plants and animals [10] by exposure to high heat and pressure in the absence of oxygen in the Earth's crust over hundreds of millions of years. [11]
The use of fossil fuels in the 18th and 19th century set the stage for the Industrial Revolution. Fossil fuels make up the bulk of the world's current primary energy sources. In 2005, 81% of the world's energy needs was met from fossil sources. [3] The technology and infrastructure for the use of fossil fuels already exist.
The two main carbon isotopes are 12 C and 13 C. Plants absorb the lighter isotope, 12 C, more readily than 13 C. [25] Because fossil fuels originate mainly from plant matter, the 13 C/ 12 C ratio in the atmosphere falls when large amounts of fossil fuels are burned, releasing 12 C.
The entire uncovering was captured by the documentary crew, who agreed to tag along after Lyson had only mentioned a few details about how the boys were digging up a dinosaur fossil.
An energy transition is a broad shift in technologies and behaviours that are needed to replace one source of energy with another. [14]: 202–203 A prime example is the change from a pre-industrial system relying on traditional biomass, wind, water and muscle power to an industrial system characterized by pervasive mechanization, steam power and the use of coal.
