From the original Blue Marble photo shot back in 1972 to the new high-definition Blue Marble images to a screen shot of the very first video image of Earth taken by a weather satellite in 1960 ...
The geothermal heat flow from the Earth's interior is estimated to be 47 terawatts (TW) [12] and split approximately equally between radiogenic heat and heat left over from the Earth's formation. This corresponds to an average flux of 0.087 W/m 2 and represents only 0.027% of Earth's total energy budget at the surface, being dwarfed by the 173 ...

Electricity generators are driven by steam or gas turbines in a thermal plant, or water turbines in a hydropower station, or wind turbines, usually in a wind farm. The invention of the solar cell in 1954 started electricity generation by solar panels, connected to a power inverter. Mass production of panels around the year 2000 made this economic.
This is a list of countries and dependencies by annual electricity production. China is the world's largest electricity producing country, followed by the United States and India. Data are for the year 2023 and are sourced from Ember unless otherwise specified. [1] Links for each location go to the relevant electricity market page, when available.
The Images of Change project provides side-by-side photos of the same place over time to document the environment changes caused by nature and man. NASA's before and after images show Earth's ...
Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry , it is the stage prior to its delivery ( transmission , distribution , etc.) to end users or its storage , using for example, the pumped-storage method.
Wind-generated electricity met nearly 4% of global electricity demand in 2015, with nearly 63 GW of new wind power capacity installed. Wind energy was the leading source of new capacity in Europe, the US and Canada, and the second largest in China.
