But, we cannot ignore the high-ini-tial cost and its dependence on clear weather, it is not always available, and methods of storage and stop-gap are required for when it is cloudy or raining outside.Nearly half of all new electricity generation in Europe is either from wind or solar energy. Some countries are already working toward phasing-out fossil fuels, apart from U.S. & Eu-rope, countries like India, China, and Brazil are coming in a massive way to shift their conventional source of en-ergy towards solar energy. Germany (including Japan & Russia) being the most prominent example, which gets 15 percent of its energy from Nuclear Power now, wants to phase it out by 2021 with a goal to supply 80 percent of its electricity from renewables by 2050.In 2014, renewable sources, such as wind, geothermal, solar, biomass, and burnt waste, provided 19 percent of the total energy consumed worldwide, with roughly half of that coming from traditional use of biomass. The most important sector is electricity with a renewable share of 22.8 percent, most of it coming from hydro-power with a share of 16.6 percent, followed by wind with 3.1 percent. There are many places around the world with grids that are run almost exclusively on renewable energy. At the na-tional level, at least 30 nations already have renewable en-ergy contributing, more than 20 percent of energy supply.The Bio-energy (ethanol from Sugarcane) is also one of the other alternative for the developing countries in view of daily huge garbage disposal problem, human & cattle waste. This will support developing countries due to they are having huge uncultivated/waste land and high population.The process of converting solar energy into electricity doesn't directly cause pollution, although the manufac-turing of solar panels, their transportation and installation may affect the environment. The overall level of pollution in an area can diminish the effectiveness of solar panels, as high levels of smog and other particulates partially oc-clude the sun's rays. The limitations of renewables like Wind and Solar is their irregular nature which requires storage, but storage of power is expensive. Though Solar PV cost is coming down, its efficiency is still around 15 percent at field level. Dust is a big problem in developing countries for wider claim of photovoltaic solar panels.The solar power made by capturing energy from sun-light. The photovoltaic solar energy is the most common type and is produced when photons contained in sunlight hit a silicon solar panel. The gen-erated electricity is then either transferred di-rectly to the electrical grid or stored in a bat-tery until it's needed. A benefit of solar energy is its ability to provide electricity to homes and facilities in areas that are not connected to a conventional electric grid. Installing so-lar panels is less expensive than laying the high-voltage wirelines for connection. The other type of solar energy is called solar thermal, which is made by using the heat from the sun to heat water. The Solar thermal energy can be used to provide hot water for homes, hotels, and swimming pools. There are a number of solar thermal power plants around the world which are using solar energy for converting into thermal energy.The easiest way to reduce our large-scale carbon foot-print is to become a solar energy producing country and replace the traditional use of fossil fuels with solar power which is free given by Mother Nature to mankind on this planet `Earth' where we live. Our transportation is the fast-est growing source of CO2 globally. As per International Transport Forum, the world's car population could reach 2.5 billion by 2050, which clearly shows that 87 million barrels of oil produced globally each day could raise to 120 million barrels.To overcome from this global problem, the key is to switch to electric cars which is a bigger game-changer on the adverse climate impact of the world's cars, although all the world's car manufacturers started electric (battery) cars. According to a survey only in the U.S. in the year 2014, around 119,710 plug-in vehicles (electric cars) were sold-out of 16.5 million totals, and the numbers are small-er around the world. Electric cars are initially expensive, The easiest way to reduce our large-scale carbon footprint is to become a solar energy producing country and replace the traditional use of fossil fuels with solar power
