Solar Powered Traffic Light Solar traffic lights are signaling devices powered by solar panels positioned at road intersections‚ pedestrian crossings and other locations to control the flows of traffic. They assign the right of way to road users by the use of lights in standard colors (red - amber/yellow - green)‚ using a universal color code (and a precise sequence to enable comprehension by those who are color blind). Most of the solar traffic lights have battery back-up for functioning during

ASTOUNDING SOLAR ENERGY FACTS What is solar energy? People often think of solar energy as solar panels mounted on roofs in sunny neighborhoods. This is only part of solar energy (“Solar energy facts‚”2012). Solar energy is the oldest energy source. Plants‚ animal and the microbial life have been using it as a principle energy source since the times of creation. It is in the form of heat and light. In the past years‚ people have tapped solar energy enabling it to be used at all times; including

Solar Power In India India’s power sector has a total installed capacity of approximately 1‚46‚753 Megawatt (MW) of which 54% is coal-based‚ 25% hydro‚ 8% is renewables and the balance is the gas and nuclear-based. Power shortages are estimated at about 11% of total energy and 15% of peak capacity requirements and are likely to increase in the coming years. In the next 10 years‚ another 10‚000 MW of capacity and investment of about Rs. 24 lakh crore are required. Fortunately‚ India lies in sunny
