Sourced from Ribes nigrum (a plant native to parts of Europe and Asia), black currant extract is typically derived from black currant fruit or from the oil of black currant seeds. Black currant extracts are widely available in dietary supplement form. Black currant oil contains gamma-linolenic acid, an essential fatty acid found to reduce inflammation. In addition, black currant berries (a substance often consumed as a whole food) contain high amounts of anthocyanins, a type of antioxidant.
Hydroelectric energy is the cleanest form of renewable generation as it does not release any harmful gases, carbon dioxide, and other pollutants which directly or indirectly affect the environment.
Hydroelectric power is currently the largest producer of renewable power in the United States. It produced around 6.52% of the nation's total electricity in 2016 which was 43.62% of the total renewable power in the country. The United States is the fourth largest producer of hydroelectricity in the world after China, Canada and Brazil.
