Renewable Energy- Hydro Electric & Others

Hydroelectric via dams has been a source of reliable, affordable, and relatively clean energy for almost 90 years. There are still environmental concerns and only a very limited number of future locations. Two-thirds of the Earth is covered by oceans and tidal flow seems to be a logical source of renewable energy. There are hurdles that must be overcome, but big advantages

 Advantages of building tidal power stations

Against the background of catastrophes and accidents that occur at nuclear power plants rarely, but leave a memory of themselves for a long time, alternative energy sources look like a safe alternative. And although there are enough difficulties in the construction of tidal power plants, there are also a lot of advantages:

  1. Environmental friendliness. In the case of TEC, the probability of a technogenic catastrophe followed by contamination of large areas is reduced to almost zero. There are no harmful emissions into the atmosphere from fuel combustion.
  2. Reliability. Tidal power plants operate steadily both in standard mode and at peak loads.
  3. Low energy cost. Compared with other types of power plants, PES is characterized by low energy cost, which was confirmed by real operating results.
  4. High efficiency. The efficiency of conversion of natural energy into usable reaches 80%, while wind power plants give up to 30% efficiency, and solar energy – on average 5-15%, but in some cases, it was possible to fix 35% efficiency.

There are also other prospects for capturing energy from the ocean.
