    Alessandro Volta invented the Voltaic Pile
    In the Pile that Volta described in 1800, a disk of copper is placed at the bottom, followed by a disk of cloth soaked in brine or acidulated water, followed by a disk of zinc. More sets of copper-cloth-zinc disks is placed on top, until the pile reaches a height of about 30 cm. The positive end of the pile is the bottom copper disk, and the negative end is the top zinc disk. The three glass rods serve to confine the disks into a vertical pile.

    http://en.wikipedia.org/wiki/Solar_powerSolar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP) or to split water and create hydrogen fuel using techniques of artificial photosynthesis. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam.

    The first windmill for electricity production is built by Professor James Blyth of Anderson's College, Glasgow (now Strathclyde University). The professor experiments with three different turbine designs, the last of which is said to have powered his Scottish home for 25 years.

    Henri Becquerel discovered the radioactivity
    http://www.chem.duke.edu/~jds/cruise_chem/nuclear/discovery.htmlIt was the month of February in the year of 1896. Antoine Henri Becquerel, a French scientist, was conducting an experiment which started with the exposure of a uranium-bearing crystal to sunlight. Once the crystal had sat in the sunshine for a while, he placed it on a photographic plate. As he had anticipated, the crystal produced its image on the plate. Becquerel theorized that the absorbed energy of the sun was being released by the uranium in the form of x-rays.

    http://www.bicyclecity.com/Bicycle-City-Alternative-EnergyPrince Piero Ginori Conti proved in the year 1904 that electrical energy can be generated by geothermal fluids. His illustration of this fact involved lighting five light bulbs using geothermal energy. A mere two years later, his work on geothermal energy (specifically natural endogenous steam) was employed commercially to power the motors for drilling equipment in a small Italian town called Larderello. Shortly the entire town of Larderello was lit up by geothermal energy. The capacity of their
