In 2010 renewable energy accounted for 16.7% of total energy consumption.
Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. The Geothermal energy of the Earth's crust originates from the original formation of the planet (20%) and from radioactive decay of minerals (80%). [ 1 ] [ 2 ] The geothermal gradient , which is the difference in temperature between the core of the planet and its surface, drives a continuous conduction of thermal energy in the form of heat from the core to the surface.
A biofuel is a type of fuel whose energy is derived from biological carbon fixation . Biofuels include fuels derived from biomass conversion, as well as solid biomass , liquid fuels and various biogases . [ 1 ] Biofuels are gaining increased public and scientific attention, driven by factors such as oil price hikes and the need for increased energy security . However, according to the European Environment Agency , biofuels address global warming concerns only in specific cases. [ 2 ]
Natural gas extraction by countries in cubic meters per year.
Hydroelectricity is the term referring to electricity generated by hydropower ; the production of electrical power through the use of the gravitational force of falling or flowing water.
Rain is liquid water in the form of droplets that have condensed from atmospheric water vapor and then precipitated —that is, become heavy enough to fall under gravity .
Tidal power , also called tidal energy , is a form of hydropower that converts the energy of tides into useful forms of power - mainly electricity.
Hydrogen is a chemical element with symbol H and atomic number 1. With an atomic weight of 1.007 9 4 u ( 1.007 8 25 u for hydrogen-1 ), hydrogen is the lightest element and its monatomic form (H 1 ) is the most abundant chemical substance, constituting roughly 75% of the Universe's baryonic mass. [ 7 ] [ note 1 ] Non- remnant stars are mainly composed of hydrogen in its plasma state.
But so much on every other type of energy. by Apr 28
So little on Wiki about Nuclear Energy but so overley used....I sure a why is asked and anaswer should be given but none will. by Apr 28
