Solar Energy Topics Solar technologies use the sun’s energy and light to provide heat‚ light‚ hot water‚ electricity‚ and even cooling‚ for homes‚ businesses‚ and industry. More basic information about solar is also available. Solar Technologies Photovoltaics (PV) Photovoltaic solar cells‚ which directly convert sunlight into electricity‚ are made of semiconducting materials. The simplest cells power watches and calculators and the like‚ while more complex systems can light houses and

The Economics of Renewable Energy in Kenya 1.0 BACKGROUND 1.1 Introduction The Kenyan economy will increasingly feel the impact of the Government’s commitment to reducing carbon emissions‚ including targets for greater use of energy from renewable sources. The Government describes its targets for renewable as challenging; others have suggested they are unachievable. In any event‚ the effort to meet them will come at a cost and‚ if not properly managed‚ risks distracting attention from other

his friend’s house. He has to exert a 110 N horizontal force to push the car at a constant speed. How much thermal energy is created in the tires and road during this short trip? thermal energy is created in the tires and road = 110 * 150 =16500 J A 30 kg child slides down a playground slide at a constant speed. The slide has a height of 4.0 m and is 7.0 m long. Using energy considerations‚ find the magnitude of the kinetic friction force acting on the child. The friction force F is parallel

Energy content is an important property of food. The energy your body needs for running‚ talking‚ and thinking comes from the food you eat. Energy content is the amount of heat produced by the burning of 1 gram of a substance‚ and is measured in joules per gram (J/g). Usually‚ fat-rich foods like peanuts and cashews provide more energy than just carbohydrates like marshmallows. You can determine the energy content by burning a portion of food and capturing the heat released to a known mass of

SMART ENERGY METER A smart meter is usually an electrical meter that records consumption of electric energy in intervals of an hour or less and communicates that information at least daily back to the utility for monitoring and billing purposes. Smart meters enable two-way communication between the meter and the central system. Unlike home energy monitors‚ smart meters can gather data for remote reporting. Smart Meters" usually involve real-time or near real-time sensors‚ power outage notification

PREPAID ENERGY METER The present system of energy billing is error prone and also time and labor consuming. Errors get introduced at every stage of energy billing like errors with electro-mechanical meters‚ human errors while noting down the meter reading‚ and errors while processing the paid bills and the due bills. There are many cases where the bill is paid and then is shown as a due amount in the next bill. There is no proper way to know the consumer’s maximum demand‚ usage details‚ losses
