The U.S. Energy Information Administration (EIA) estimates that about 11% of world marketed energy consumption is from renewable energy sources (biofuels, biomass, geothermal, hydropower, solar, and wind) with a projection for 15% by 2040.
Not to be confused with antibody. An antibiotic (or antibacterial) is something that kills bacteria or slows the growth of bacteria. They are used as medicines to cure diseases caused by bacteria. Antibiotics are no use against viruses. Penicillin, the first natural antibiotic, is produced by a fungus. Production started in 1939, and now it is made by chemical synthesis.
Antiviral drugs are a class of medication used specifically for treating viral infections. Like antibiotics and broad-spectrum antibiotics for bacteria, most antivirals are used for specific viral infections, while a broad-spectrum antiviral is effective against a wide range of viruses. Unlike most antibiotics, antiviral drugs do not destroy their target pathogen; instead they inhibit their development.
