Lead-acid batteries were first developed in the 19th century. They are widely used in vehicles and grid services, such as spinning reserve and demand shift . Their main advantages include ease of installation, low maintenance costs, maturity, recyclability, a large lifespan in power fluctuation operations, and low self-discharge. . Lithium batteries are the most widely used energy storage devices in mobile and computing applications. The development of new materials has led. . Flow batteries store energy in aqueous electrolytes and act in a similar way to fuel cells. These batteries convert chemical energy into electrical. . Sodium Beta batteries are a family of devices that use liquid sodium as the active material in the anode and other materials in the electrolyte. These batteries are competitive in their use for large-scale energy. . Nickel-Cadmium batteries have been used since 1915 and represent a mature technology. They are rechargeable and have a positive electrode made from Nickel Oxide Hydroxide. [pdf]

The negative environmental impacts associated to the use of large hydropower plants have helped to focus the attention on small-scale plants, which reduce these impacts considerably. In Colombia, there is an i. . Hydropower is the main renewable energy source in terms of global electricity production. It p. . 2.1. Current statusAs it was stated before, Colombia has a great hydrological potential thanks to its privileged geographical location. According to statistics of Int. . Colombia is within the five countries with the largest hydraulic capacity, with an average flow in multi-year major rivers of 52.07 m3/s [28]. However, despite having a huge hydroelectri. . In Colombia, the interest for SHP projects has been increasing since the beginning of the 1990s. However, the general tendency has been the construction of large hydropower inste. . In Colombia the theoretical potential does not support the applicability of small hydropower in all areas of the country, since the field of action of the technology develops best in. [pdf]
