Renewable energy is energy that comes from resources which are continually replenished such as sunlight, wind, rain, tides, waves and geothermal heat. About 16% of global final energy consumption comes from renewable resources, with 10% of all energy from traditional biomass, mainly used for heating, and 3.4% from hydroelectricity. New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for another 3% and are growing very rapidly.The share of renewables in electricity generation is around 19%, with 16% of electricity coming from hydroelectricity and 3% from new renewables.
Below you can see a very interesting infographic designed by the Carrington College in California which illustrates the types of renewable energy, their correlation with the jobs, the renewable energy use by state and at last the global development of primary energy consumption reference scenario VS energy (r)evolution. The graphic can be used as a guide for the newbies in energy sector.
