Solar Energy: Powering Our Future Today nearly half of the world’s energy is provided by petroleum. What began as a cheap and abundant way to provide energy‚ has become expensive‚ environmentally harmful‚ and finite. With population explosions and the demands of modern lifestyles‚ the world’s need for energy production has become far too much for fossil fuels to keep up with. Experts say that the Earth’s stores of petroleum will be depleted by 2050. The need to find a viable source of energy within

source of energy? Energy is essential for life. We use it in factories‚ in cars‚ airplanes‚ trains and ships. To heat food‚ light our houses etc. However‚ energy consumption is different in different countries. Since always human beings have used energy sources to do work or produce heat. Firstly‚ they used domestic animals or their physical forces. After‚ they used the wind and the water. Then‚ they exploited the use of fossil fuels and nuclear energy. In the near future we hope new energy sources

Hydraulics – CIVL 2130 Conservation of Energy Aim The aim of this lab experiment is to observe the flow behaviour of water through a pipe of variable section. Firstly‚ we will investigate the interchange of pressure and kinetic energy at each diameter change. Secondly‚ we will study the application of this interchange to the flow metering devices. Lastly‚ energy losses due to friction and pressure effects are estimated. Experimental Apparatus [pic] Pre-lab Question Pressure varies

Alternate energy. According to Oxford Dictionary‚ Alternative Energy is energy fueled in ways that do not use up natural resources or harm the environment. Alternative energy refers to energy sources that have no undesired consequences such for example fossil fuels or nuclear energy. Alternative energy sources are renewable and are thought to be "free" energy sources. They all have lower carbon emissions‚ compared to conventional energy sources. These include Nuclear Energy‚ Wind Energy‚ Solar Energy

Energy crisis is a major challenge that should be overcome in modern times when people have embraced the use of electric devices in performing various activities. Consequently‚ the use of these electric devices leads to heavy consumption of electric power that calls for the adoption of energy efficient appliances. Energy efficiency refers to reduced use of energy in a given service (Dorsi & Krigger‚ 2008). The reduced consumption of energy is as a result of technological advancement as well as from

is their difference in momentum? What is their difference in kinetic energy? 2. A 12 g bullet is fired horizontally into a 96 g wooden block initially at rest on a horizontal surface. After impact‚ the block slides 7.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.60‚ what was the speed of the bullet immediately before impact? You have to use the conservation of the total energy of the system to do this problem: Initially‚ you have‚ in the total

KINETIC ENERGY Objects have energy because of their motion; this energy is called kinetic energy. Kinetic energy of the objects having mass m and velocity v can be calculated with the formula given below; K=1/2mv² Kinetic energy is a scalar quantity; it does not have a direction. Unlike velocity‚ acceleration‚ force‚ and momentum‚ the kinetic energy of an object is completely described by magnitude alone. Like work and potential energy‚ the standard metric unit of measurement for kinetic energy is
