Renewable energy is the necessity of life. The signs of global warming are on alarming stage. Therefore the geographers and certain green conscious people are researching more and more on renewable energy to gain more from earth without harming her. There are so many types of natural resources where we gain renewable energy. Solar and wind energy is the most common type of renewable energy.

Solar power systems are the conversion of sunlight into electricity, either directly using photovoltaic or using concentrated solar power indirectly. Photovoltaic converts light into electric current by using the photoelectric effect. Concentrating Solar Power (CSP) systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam, so that the concentrated heat is then used as a heat source for a conventional power plant. A wide range of concentrating technologies exists; the most developed are the parabolic trough, the Stirling dish, the concentrating linear fresnel reflectors and the solar power tower. There are various techniques used to track the sun and focus light. In all of these systems a working fluid is heated by the concentrated sunlight, and is then used for power generation or storage energy.
Scientist are innovating a new techniques to get eco friendly solution for daily performance tasks. Like, an automotive solar battery charger can recharge your car battery by utilizing the power of sun. These batteries are becoming very popular since everyone has become concerned about the high cost of energy and finding better ways to save the environment.
Wind power systems refer to the transition of the energy present in natural wind to convert into electricity. Wind Power systems can be produced either in huge commercial scale like large wind farms or smaller turbines for a much smaller electricity consumption base. Wind farms are generally connected to regional or national electrical grids. Effective wind power generation is greatly dependant on the selection of wind turbine sites. The primary requirement is the availability of wind and other essentials include the presence of electrical transmission lines and land acquisition expenses. Wind power generation capacity suffers from uncontrollable external factors and the flow of wind over a certain area may vary time to time. Variation in time also applicable from day to day and from hour to hour.
A hybrid solar wind turbine generator is a reliable source of alternative energy. It uses solar energy combined with wind energy to create a stand-alone energy source that is both consistent and dependable. Solar power and wind power are the two most available sources of power on the planet; both are renewable energy sources that are plentiful all year round in all areas. The hybrid solar wind turbine generator uses solar panels that collect light and convert it to energy along with wind turbines that is responsible for collecting energy from the wind. Solar wind charge controllers regulate the charging of the energy before it is stored in the banks of the battery.
