Wind power, form of energy conversion in which turbines convert the kinetic energy of wind into mechanical or electrical energy that can be used for power. Wind power is considered a renewable energy source. Historically, wind power in the form of windmills has been used for centuries for such tasks as grinding grain and pumping water. Modern commercial wind turbines produce electricity by using rotational energy to drive an electrical generator. They are made up of a blade or rotor and an enclosure called a nacelle that contains a drive train atop a tall tower. The largest turbines can produce 4.8–9.5 megawatts of power, have a rotor diameter that may extend more than 162 metres (about 531 feet), and are attached to towers approaching 240 metres (787 feet) tall. The most common types of wind turbines (which produce up to 1.8 megawatts) are much smaller; they have a blade length of approximately 40 metres (about 130 feet) and are attached to towers roughly 80 metres (about 260 feet) tall. Smaller turbines can be used to provide power to individual homes. Wind farms are areas where a number of wind turbines are grouped together, providing a larger total energy source.
Solar energy, radiation from the Sun capable of producing heat, causing chemical reactions, or generating electricity. The total amount of solar energy incident on Earth is vastly in excess of the world’s current and anticipated energy requirements. If suitably harnessed, this highly diffused source has the potential to satisfy all future energy needs. In the 21st century solar energy is expected to become increasingly attractive as a renewable energy source because of its inexhaustible supply and its nonpolluting character, in stark contrast to the finite fossil fuels coal, petroleum, and natural gas
Solar Energy is derived from the suns radiation, and is truly renewable energy source. It is abundant in nature and can be very efficiently converted into useful form of power and clean energy. Catering your energy needs with Solar reduces your electricity bills, can be remotely operated and have the lowest maintenance costs.
