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

Dark energy what is it? Dark energy is a unknown energy said to take up 70 percent of the universe. The energy is a repulsive gravitational effect that is causing the universe to accelerate out-ward. No one knows exactly what dark energy is or where it comes from. Dark Energy is a new idea. Little is known about dark energy‚ yet it takes up a huge amount if the universe. Scientist were able to show the universe was expanding at an accelerated rate by measuring the red-shift of an object by comparing

SOLAR ENERGY INTRODUCTION SOLAR ENERGY is the radiant energy that we receive from the sun in the form of heat and light. It is an inexhaustible source of energy. Solar Energy is the ultimate source of most of the sources of energy that we use. The wind energy‚ water energy‚ energy of fossil fuels and the energy in food are due to solar energy. SOURCE OF SOLAR ENERGY The discovery of radioactivity led some scientists to suggest that the energy released during radioactive decay of radioactive

Energy For The Future John Hosking We live in a world where technology has outgrown us‚ and where we have outgrown our world. Beyond our dependence on the earth’s resources for simple necessities we have grown dependent on it for energy. Since we developed our need for energy the quest to find it has been perpetual. Over the last 200 years that need has been mainly supplied by fossil fuels‚ predominately coal. Recently‚ interest in the development for more sustainable energy options has

Why should we save energy in schools? Saving energy leads to reduce carbon emissions‚lower costs and conserves the supplies we have.They are also working in support with high schools to support energy efficiency."We believe energy efficiency is the cheapest and cleanest form of "new" energy the world has." - energy efficiency unit of Chevron.Even though energy suppliers want your business‚ they are looking for more of an investment instead of wasting energy when it isn’t necessary. They believe

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

forces involved. Two of the main forces experienced are called potential energy and kinetic energy. Potential energy is the energy an object has depending on the position of it. For example the higher an object is the higher the potential energy is and the lower an object is the less potential energy it will have. Kinetic energy is also a main type of force that is involved with rollercoasters. Kinetic energy is the energy an object will have as it is in motion. There are many different types of
