Emissions rose an 'unsustainable' 2% in 2018: study

Global carbon emissions grew by 2.0 percent last year, the highest rate since 2010-2011, a closely-watched review by energy giant BP said Tuesday, calling the trend "unsustainable".

Wood consumption in energy generation continues to increase

In 2018, the consumption of wood fuels reached yet another record as a result of the increased use of black liquor produced by the forest industries. Heating and power plants consumed the same amount of solid wood fuels as ...

Electricity generation

Electricity generation is the process of creating electricity from other forms of energy.

The fundamental principles of electricity generation were discovered during the 1820's and early 1830's by the British scientist Michael Faraday. His basic method is still used today: electricity is generated by the movement of a loop of wire, or disc of copper between the poles of a magnet.

For electric utilities, it is the first process in the delivery of electricity to consumers. The other processes, electric power transmission, electricity distribution, and electrical power storage and recovery using pumped storage methods are normally carried out by the electrical power industry.

Electricity is most often generated at a power station by electromechanical generators, primarily driven by heat engines fueled by chemical combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. There are many other technologies that can be and are used to generate electricity such as solar photovoltaics and geothermal power.
