Solar energy: Solar energy is developed by synthesizing the radiation energy of the Sun. The solar rays consist of hydrogen power energy in the ultraviolet form. The green plants utilize the sun ray for producing their food. The solar energy of the sun is used for generating electricity and heat energy. Solar energy is used by most of the people across the globe. Most of the Sunlight is sent back into the space. Only one third of the solar energy is kept on the earth’s atmosphere. Rest of the sun rays are radiated back. The Sun rays are extracted by using the Solar thermal and photovoltaic cells. The solar energy can be classified into two types active and passive. The use of passive solar energy can be done by utilizing the position, duration and intensity of the sun rays fir heating a particular region. The active solar energy radiation is used for generating electrical and thermal energy. The benefits of using the solar energy are that the energy source is sustainable and renewable. It is natural source of energy and provides the energy source for the generation of electricity. It is noise free solution for the generation of power and electricity.
Wireless Transmission of Power: The wireless transmission of power can be used as a mean for transmitting the energy. It is a simple transmission of power source to the electrical load (for example: consuming device or power grid of the electricity). However the transmission does not require the use of any man made conducting devices. The transmission uses the transmission technologies such as electromagnetic fields and solenoid magnets. The transmitter is conducted to the power source and it conveys the field of energy across the intervening space in between the conductance materials. The wireless power generation falls into two categories such as radioactive and non radioactive. The non radioactive techniques consist of power transfer using the magnetic fields (inductive coupling technique in between the wire coiled). The radioactive technique uses the far field application for the energy transmission. The far field is termed as power beaming. The energy in this technique is being transmitted in the form of laser or microwave beams. The benefits of using the wireless power generation are its waterproof and lack of physical hardware. The device uses wireless conductance for transmitting the energy and hence it does not have any fear of getting attack from physical harms.
Wind Energy: The wind energy generation is a popular method for power generation without affecting the natural environment. The process consists of generating the power by using the force of wind motion. The force of the wind is used for rotating the fans of the windmill. The windmill fans in turn rotate the motor for generating power. In this process the win potential energy is converted into the mechanical energy. The mechanical energy is converted to produce electric energy. The kinetic energy would be used for producing the electric energy. The generation of wind is done due to the uneven heating in the earth’s atmosphere and the variation in the surface temperature of the earth. The turbines would be used for the energy generation. The equation for the wind power generation is:
P=1/2*(?AV^3) (where P is power generated, ? is the density, A is the area and v is the velocity)
The main advantage of using the wind energy is that it is a clean power generation technology. The wind power generation would not affect the environment. It is also sustainable in nature and the resource of power generation is abundant in nature. The cost effectiveness of the wind power generation is another benefit of using it for power generation.

The best non exhaustible power generation solution is the hydro power generation. It is the cheapest and cleanest power resource that has been synthesized in the present world. It is an innovation technology of power generation with maximum potential. It can exploit the hydro power potential for supplying strength to those country territories with very little access to core power reserves and sources. It additionally disposes the greater part of the negative natural impacts connected with huge hydro projects. The vitality in the streaming water can be utilized to deliver power. Waves result from the collaboration of the twist with the surface of the ocean and speak to an exchange of vitality from the twist to the ocean. Vitality can be extricated from tides by making a repository or bowl behind a torrent and after those going tidal waters through turbines in the blast to produce power. The hydro power can be synthesized by using the dams, tidal wave and reservoirs. The hydro power generation is a simple procedure. The water is stored at a higher altitude by making brick wall in the form of dams and reserves.
Due to the storage of water body at higher altitude, a potential energy is stored in the water body. When the water is allowed to flow from higher to lower height, the potential water energy is converted to kinetic energy. The kinetic power energy is used for generating electrical energy. The tidal waves of the oceans and seas also have stored potential energy that can be synthesized for generating power energy. The energy is obtained by developing the storage of waves and tides at the coasts. It would be benefit for synthesizing the power using the tidal energy. The advantages of using the hydropower are that it has clean and compact process for power generation. There would be no chance for polluting the atmosphere or environment. The production of the hydro power could be done domestically. Hence it would give benefit for producing the power by using the hydro power. The vitality produced through hydropower depends on the water cycle, which is driven by the sun, making it a renewable power source, making it a more solid and reasonable source than fossil energizes that are quickly being drained. Impoundment hydropower makes repositories that offer an assortment of recreational open doors, outstandingly angling, swimming, and sailing.
Most water power establishments are required to give some community to the repository to permit the general population to exploit these open doors. Some hydropower offices can rapidly go from zero energy to most extreme yield. Since hydropower plants can produce energy to the framework instantly, they give vital move down power amid real power blackouts or interruptions. Notwithstanding a feasible fuel source, hydropower endeavours deliver various advantages, for example, surge control, water system, and water supply.
Hence it can be implied that the power resources of future can be benefited by the use of hydro power generation. The ease of hydro power generation would make it sustainable to use. It would decrease the issues of power shortage in future. The limited resources of coal and petroleum power consumption could be exhausted if it is continued at the present rate of consumption. Hence it is important for keeping the hydro power as a subsidiary power source. The natural resource is limited and it can be saved by using the hydropower energy generation. The hydro power generation also have economic benefits. The source is naturally available and it does not cost much for synthesizing the power resources. It would also help in decreasing the rate of power supply for general use. The industries can use it for decreasing their cost of production.
