Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the photovoltaic effect.[2] Photovoltaics were initially, and still are, used to power small and medium-sized applications, from the calculator powered by a single

significant increase in production of greenhouse gases between the 19th and 20th century (Davis, 11). Increase in population has led to increased transportation and manufacturing. This implies rise in the combustion of fossil fuels including oil, gas and coal. Combustion of fossil fuels leads to emission of, among others, carbon dioxide into the atmosphere and this account for over 80% of the Carbon dioxide emission (Alastair, 77). Parsons (25) notes that the gases produced are more stable that stay
