Instead, the recent renewable energy such as solar, wind, biomasses, etc. are not available 100% efficiency. Therefore, gravity power generation is one of the methods of generating a power that fulfils the energy demand within a few instants of day. Gravity is available all over the earth, so producing power using gravity is the easy…
How is electricity made? To produce electricity, energy must undergo a series of transformations before being transported and distributed in our homes. There are several sources of energy. Certain renewable energies have been known for a very long time, such as solar and wind. Other, more recent energies such as marine energy or the thermodynamic…
Despite the Covid-19 pandemic, global competition continues to reach higher solar efficiency and last month at least three records broke the efficiency of solar panels. Hexagonal solar cells with an efficiency of 47.1% The first invention was by scientists at the American Renewable Energy Laboratory NREL, which has developed hexagonal solar cells…
