Smart Street light reduces power bill of Municipal Corporation

Street lighting is a very important public service provided by public authorities at the local and municipal level. Good lighting is essential for public safety, road safety, and overall ambience of a place. Street lighting ensures visibility in the dark for pedestrians, motorists and cyclists, thereby reducing road accidents. Street lighting also indirectly facilitates crime prevention by increasing safety and security of people and property (private and public). Good street lighting effects can boost and add to the appeal of a city. Some problem areas However, many street lighting facilities are old and outdated and therefore not efficient. This leads to higher energy requirement and high maintenance too. For municipalities with such outdated systems, street lighting can account for around 30-50% of their entire power consumption. For example, in India most of the street lights are sodium vapour lights, metal halides, and some CFLs. An estimated 20 to 40% of the energy produced in India goes into the lighting of street lights. Although, with the rise in solar technology, solar powered streetlights are also seen in some areas now. In the current lighting situation there is no baseline data or system which provides information regarding faulty lights. Electricity theft is another problem area and as of now there is no particular method of finding out the amount of electricity consumed by each light. Thus there is no specific way to determine if there is a leak somewhere in the line. Despite electricity shortage, it has been frequently observed that street lights are working/on, even during the day. This is wastage of electricity. It could be due to human error or negligence. However, in the end, the financial burden lies on the municipal corporation. Suggested solutions Since streetlights are such an essential part of every city, supporting people and businesses with safety, security and convenience, it would be better (financially and environmentally) if we could use our street lighting network in a smarter, more intelligent way rather than the current on-off system. All parts of the world are now converting to energy-efficient LED street lighting, which is brighter and more adjustable. LED lights have two key benefits- energy efficiency and long service life. As a longer service life means considerable reductions in maintenance costs. Intelligent/smart control systems create additional savings potential as the street lighting level can be adjusted (reduced or increased) in line with requirements, thus providing substantial energy savings. Automated control and monitoring system provides better functionality and efficiency which helps in tracking energy consumption. Smart street lighting technology can provide detailed analytics that would be helpful in the execution and maintenance of street lighting. Smart street lighting solutions (IoT based analytics and remote monitoring) will empower municipal Continue Reading

Smart city- Battery operated vehicles for less pollution and other advantages

It is known that conventional vehicles produce a lot of carbon emissions that get ejected into the atmosphere. This causes severe pollution and is also one of the main causes for global warming. Smart cities need to make reforms towards energy and transport model for both, private and public alike. This would minimize environmental and acoustic impact of transport, improve air quality and thus improve citizen’s quality of life.One of the leading smart city initiatives involves controlling pollution in all its forms. This can be done by reducing the number of gasoline vehicles on the roads and replacing them with battery operated/electric vehicles. The use of Electric vehicles (EVs) or battery operated vehicles are seen by governments as an alternative to conventional vehicles and are instrumental in cutting down emissions and thereby reducing global warming.To understand how EVs are better and produce far less pollution than their gasoline counterparts we need to look into the lifecycle of vehicles (from manufacturing of the vehicle’s body and battery to its final disposal/reuse).  Each stage of the manufacturing process is linked with carbon dioxide (main cause of pollution) and other greenhouse gas emissions. But the emissions differ in gasoline powered vehicles and battery operated vehicles during the manufacturing process.The main component that distinguishes an EV from a gasoline vehicle is its battery. Since electric vehicles store power in large lithium-ion batteries which are material and energy intensive to produce, their global warming emissions at the manufacturing stage usually exceed those of conventional vehicles.These differences in emission at the production/manufacturing stage change as soon as the EV hits the road and the environmental picture starts to improve. In other words, the extra emissions associated with EV production are rapidly negated by (reduced) no emission from driving as against the gasoline powered vehicles which emit carbon dioxide and other gases into the atmosphere.Advantages of an electric vehicle/battery operated vehicle:No gas requirement: Electric vehicles get power from batteries that are installed inside the car. The battery provides power to the motors for the vehicle to run and also for other functions like lights, wipers etc. The batteries are powered by electricity. Since these vehicles are charged by electricity you don’t need to buy expensive gas (fuel). Driving conventional fuel based cars is getting more expensive day by day as fuel prices are going up. It’s not that electricity is free but it is cheaper than gas and hence electric vehicles are cheaper to run.Size matters: Unlike the earlier versions of EVs which were only two seaters, vehicle manufacturing companies now offer 4 to 5 seater vehicles. Besides this, these vehicles also have autopilot features with good mile-range.Money smart: To save the fragile environment from further degradation, governments are now alert and aware and offering Continue Reading
