**Energy can’t be generated perfectly in line with the demand curve.** All energy production is subject to variation in efficacy. Green methods, such as solar & wind energy, are _particularly_ ‘bursty’ power generation methods. Booms and busts. This is why energy must be stored for use later ([[Energy Storage]]). Traditionally this storage is done via charging chemical batteries.  **** # More ## Source ## Related - [[Energy Storage]] - [[Energy Demand Curve]]
