Renewable energy is the need of the hour It is the year 2050‚ Earth is so polluted‚ vision is obscured by smog‚ lakes and streams are poisoned. Oh! What a terrible sight. This may become a reality‚ if we keep using non-renewable energy resources. Hello there! A very good morning and I am Pranav Athreya and you have guessed it right‚ I am speaking for the topic Renewable energy is the need of the hour. At present‚ the main energy sources used are non-renewable fossil fuels like coal‚ petroleum‚ and

supply beginning to dwindle‚ and the threat of climate change looming in our future‚ conservation of energy has become more important than ever before. In this personal energy audit I will analyze my energy use over the week of September 21st-27th. I made a log of any daily activities which required an energy input‚ and noted their duration. This information was then used to determine the energy required per year. As I have not been living at my current address for at least 1 year‚ I was unable

Running Head: Energy Conversion Energy Conversion Marlon Walker Professor Abdul Kahn SCI 110: Integrated Science October 21‚ 2011 Abstract Energy conversion has been a topic of debate and research for many years. Scientists conduct experiments in hopes of finding an alternative to relying on burning fossil fuels for electricity. While companies who believe their alternative is the best choice‚ debate over whose source is the “greenest”. Whether it be biomass‚ hydroelectricity‚ solar

Work & Energy Physical Science Ms.Barconey May 8‚ 2013 Work is the transfer of energy to an object by the application of a force that causes the object to move in the direction of the force. Three examples of work would be a tractor pulling a float‚ a mother pushing a baby stroller‚ and a body builder lift a barbell over their head. Work is measured in joules and the formula for work is Work=Force*Distance. Power is a quantity that measures the rate at which work is done

Biomass Energy Introduction Biomass is biological material derived from living‚ or recently living organisms. It mostly often refers to plants or plant-derived materials which are specifically called lignocellulosic biomass. As a renewable energy source‚ biomass can either be used directly via combustion to produce heat‚ or indirectly after converting it to various forms of biofuel. The source of biomass energy. Wood energy. is the largest

Security is an important factor in life on a daily basis‚people require one form of security in a particular way or the other. There are issues of crime‚ terrorism‚ poverty‚ displacement‚ health‚ education and many others which a nation has to ensure that its citizens are satisfied with. Any longer interruption of a steady and plenty flow of energy‚ particularly modern energy would massively harm a

examples of work done=force x distance What is work? Work in physics is the transfer of energy; work is done on an object when an applied force moves it through a distance. The link between work and energy is work done equals energy transferred. The units for the two are also the same (joules). E.g. 500J of work = 500J of kinetic energy. Work is calculated with the formula: work done=force x distance moved For example‚ if a force of 10 newton (F = 10 N) acts along point that travels 2 meters

Due to technical potential of 5‚000 trillion kWh per year and minimum operating cost‚ Solar Power is considered the best suited energy source for India. Today the Solar power‚ has an installed capacity of 9.84

Energy Nothing can live without energy. People‚ animals and plants need energy to live and machines need energy to work. Today‚ most of the energy we use still comes from fossil fuels like coal‚ oil and gas‚ which have been formed underground over millions of years. We called these non-renewable forms of energy because they can only be used once. Because of this‚ we need to reduce our use of non-renewable fuel and use more renewable forms of energy like that from the sun‚ wind or geothermal

Nuclear energy… Boon or Bane ? Nuclear energy? Nowadays these two words are always sticking on the society’s mouth‚ but do they know the actual meaning of it? Nuclear energy is basically defined as the energy released by the reaction within the nuclei‚ as in nuclear fission or fusion. The core reason of using nuclear energy is to generate electric power to satisfy human needs. Usage of the nuclear power plant as an energy generator came together with several boons and banes. As quoted by the
