Renewable Energy
Renewable energy is derived from the natural replenishment of renewable resources on a human timescale. Examples include sunlight, wind, rain, tides, waves, and geothermal heat. About 20% of the world’s energy consumption by humankind comes from renewable energy sources, of which about 30% comes from electricity.
Fossil-fueled power plant life emits air pollutants together with sulfur dioxide, particulate matter, nitrogen oxides, and toxic chemicals (heavy metals: mercury, chromium, and arsenic), and mobile sources, together with fossil-fueled vehicles, emit nitrogen oxides, carbon monoxide, and particulate matter. Exposure to those pollutants can motive coronary heart disease, asthma, and distinct human health problems. In addition, emissions from fossil fuel line combustion are responsible for acid rain, which has added approximately the acidification of many lakes and consequent damage to aquatic life, leaf damage in plenty of forests, and the production of smog in or near many metropolis areas.
