Hydropower
Hydropower is a technology that converts moving liquid water into mechanical energy. Great technologies come and go quickly, but hydropower will last the longest because it is the cheapest source of energy, followed by wind power later.
Hydroelectricity produces electricity from the rapid flow of water, and we can divide the amount of electricity produced by hydroelectricity into two categories: subcritical and supercritical.
Subcritical involves a stop/start cycle to generate electricity, while in supercritical mode the thermal fluid does not enter the turbine at the high rates that result in efficiency.
Advantages
Hydroelectric power was used to power water, mills, and engines, and meant the provision of additional energy from tides, stream power sources, or water pumped from underground reservoirs.
Average economic benefits excluding power increases are likely to be less than $2.5 billion per year.
There are also alternative hydropower technologies, some gaining more traction than others. Wind energy is a renewable, clean source of energy. Wind power uses the kinetic energy of the wind to turn turbine blades, which in turn turn a grid-connected electric generator. This process of generating electricity from wind is called wind power generation. More than 63 GW of electricity was generated from onshore and offshore wind in 2013, and wind power could supply more than 20% of the world’s electricity by 2050. Wind energy is a renewable, clean source of energy. Wind power uses the kinetic energy of the wind to turn turbine blades, which in turn turn a grid-connected electric generator. This process of generating electricity from wind is called wind power generation. More than 63 GW of wind power is currently installed worldwide. The largest electric power company in the world by revenue and market cap is American Electric Power Company (AEP) with annual revenues of $57 billion, assets of $30 billion and a market cap of $36 billion as of September 24 2017) at $50 per share. is more
