Out of all the alternative energy sources, this one has been most commonly adopted in the current time.
This is the energy which the earth receives from the Sun. This is one of the most promising alternative energy sources, which will be available to mankind for centuries to come. The only challenge remains to tap solar energy in the most efficient way. The solar power generation is done by using a series of photovoltaic cells where the solar rays are converted into electricity. Apart from electricity production solar energy is also being used for heating water, cooking food, etc.
The power of the wind is harnessed to propel the blades of wind turbine attached to an electric generator to generate wind energy. Wind energy is an effective alternative source of energy in areas where the velocity of wind flow is high. This is the energy developed from the wastes of various human and animal activities like the by-products and wastes from the timber industry, agricultural yields, municipal solid waste, etc.
Out of the many alternative sources of energy, this is the one which takes into account the utilization of waste material to develop energy thereby disposing of them in a profitable and effective way.
Therefore, biomass energy is considered a renewable source of energy. To answer the question of which Alternative Energy Source has been brought to picture newly, you should understand that as you are reading this, there are developments being carried on to find more and more alternative energy sources.
Alternative energy - Wikipedia
Apart from the commonly known alternative energy sources, there have been recent advancements in terms of discovering new alternative energy sources to add to the list of alternative energy sources. This is the energy tapped from the heat inside the earth. Hot rocks residing in the core of earth heat water which emits the surface of the earth with pressure and as steam. This pressurized steam can be used to run steam turbines to generate electricity. The surface of the earth is The tides in water rise and fall due to the gravity of the sun and moon.
Since we know about how the position of moon changes we can predict the rise and fall of tides. This rise and fall of tides can be utilized by setting up small dams and passing water through the turbines to generate power. As promising as the use of alternative sources of energy may sound, it is still under research as to how to tap energy from these resources in the most efficient and effective way.
Although small power generation systems can be put in place, power production from these resources on a large scale is still a challenge with hydroelectric power generation being an exception. Many countries are not yet ready to move from using conventional energy sources to the alternative energy sources as it involves a huge amount to decommission the old power generation infrastructure and establish new infrastructure. Therefore, the shift is ideal to be made in phases.
Alternative energy sources are available free of cost and do not tax the environment for their usage. If we shift to use power generated from these sources, then carbon dioxide emission from the conventional energy sources will be greatly reduced, and the problem of global warming will be solved in a few years. Also, the fast depleting traditional energy sources can be preserved.

Along with air pollution, the use of traditional energy resources also causes soil pollution and water pollution by releasing various toxins to the land and water. This can also be controlled reasonably.
