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.
When electricity is generated from flowing water, this is called hydroelectric energy, and the prefix 'hydro' refers to water. Hydroelectric energy is considered a renewable energy resource because it's an energy resource that regenerates in a short time period. You can think of this like the hair on your head. If you get a bad haircut that you don't like, you don't have to worry about it too much because it will grow back in a reasonable amount of time.
