The modern world is running with the power of fossil fuel, a kind of energy source are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals. But this kind of fuel is limited and it will run out sooner or later. But with the increase in population, the demand for fuel is going high. Scientists predict that our fossil fuel will run out within mid of the next century. So the necessity of alternative energy source becomes very important. Renewable energy can solve these problems. Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat. Renewable energy can replace conventional fuel in four distinct areas: electricity generation, hot water/space heating, motor fuels, and rural (off-grid) energy services. Like many developed countries, Bangladesh is also working with technology that can produce renewable energy. The government has installed the biggest solar power plant on the rooftop of the Bangladesh Bureau of Statistics building in Dhaka. The plant with a 200 kW (kilowatt peak) generation capacity, equivalent to lighting up 5,000 bulbs of 40 watts, will meet a significant portion of the building's demand for electricity.
