ESTIMATION OF SOLAR ENERGY FOR STREET LIGHTS IN VIT ABSTRACT A solar lighting system which can make a 18x3 w lamp glow continuously for about (7) hours if the battery is fully charged has been constructed. Here, solar energy is collected with the aid of a solar panel and thus, a battery is charged during day time with the help of a simple charging circuit. During night time, this stored energy is used to light. The device can be used for small-scale lighting applications in remote areas that are

frequently debated. The impacts of human activities cause major environmental problems such as greenhouse gases and global warming. Therefore it is essential to find out which of them has major effects on environment. The depletion of natural resources, or other environmental issues demonstrate that there is not enough awareness concerning to consequences of human activity. That is why the term of sustainability was emerged. Carbon footprint and water footprint are special tools to measure

Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished). About 16% of global final energy consumption comes from renewables, with 10% coming from traditional biomass, which is mainly used for heating, and 3.4% from hydroelectricity. New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for another 3% and are growing very rapidly. The share of renewables

Energy return on investment - which fuels win? http://www.carbonbrief.org/blog/2013/03/energy-return-on-investment-which-fuels-win/ * 20 Mar 2013, 16:00 * Mat Hope and Ros Donald By Arnold Paul The days of easy to extract fossil fuels are numbered. Companies are using more energy-intensive methods to get to conventional fossil fuels, and turning to harder-to-extract fuels such as shale gas. But do these sources give us a good return on the energy we invest? A new article investigates

our world if our energy unexpectedly disappeared? Fossil fuels are very important to our world because they provide an overwhelming majority of our world energy. So, what happens when they run out? As the world enters a new century, new source of energy such as wind power need to be used more to help the world keep running on all cylinders. According to the American Wind Energy Association, “Wind power captures the natural wind in our atmosphere and converts it into mechanical energy then electricity

human beings we need to find a safe, reliable, long term solution to our energy needs. Researchers need to find and provide information to encourage the building of nuclear power plants. Researchers should present information that leads to building more nuclear power plants in order to provide a long term, a reliable, safer energy solution. The first reason why researchers should present information is to offer a long term energy solution. Nuclear power plants can last for years when taken care of properly
