Project Background The Philippines remains as one of the best performing economies in Asia‚ as it grew 7.2% in 2013‚ which is better than the 6.8% growth posted in 2012. Its growth is based on consumption as well as growth in infrastructure investments – both public and private. Over the past two and a half decades‚ the institutions have been put in place and these include among others: restoration of democracy; transformation of telecommunications‚ public utilities (water and electricity)‚ transportation

The Coming Energy Crisis? • • All warning signs that existed prior to the energy crises of 1973 and 1979 exist today. Various energy security measures indicate that the potential for an energy shortage is high. As submitted to Oil & Gas Journal for publication February 3‚ 2003 James L. Williams‚ President‚ WTRG Economics E-mail: wtrg@wtrg.com Phone: (479) 293-4081 I. Introduction Various measures of US energy security indicate that the US might be heading for an energy crisis. Many of the warning

Energy Management H.W 1 1. A hospital is considering the purchase of a large commercial laundry dryer‚ and is attempting to decide between an electric and natural gas powered system. If electricity costs $0.06/kWh and is used with an efficiency of 90%‚ what is the equivalent price of natural gas per therm if it can be burned with an efficiency of 80%? Dimensional Analysis |$.06 |29.3 KWh |.8 efficiency | |.90 efficiency |1 therm

Calculating Efficiency. Efficiency (%) = Useful Energy Out x 100 Total Energy In Questions 1) A light bulb takes in 30J of energy per second. It transfers 3J as useful light energy and 27J as heat energy. Calculate the efficiency. 2) A kettle takes in 2000J of energy per second. It transfers 1500J as useful heat energy and 500J is wasted as sound energy. Calculate the efficiency of the kettle. Remember: In the exam they may not

Potential Energy Potential Energy is a type of energy that does not involve motion. It is the energy that is stored up. The more work done to change an object’s position or shape‚ the more potential energy it has. For example‚ a person on a ladder has more potential energy than a person on the ground because they have done more work to get up there. Kinetic Energy Kinetic Energy is the energy of motion. The more work an object has done‚ the more kinetic energy it has. the amount of kinetic

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

Renewable Energy is Best Michelle Johnson HUM/111 March 26‚ 2011 L. Flemister Renewable Energy is best America’s dependency on foreign oil is costing us more than just money; it costs us our clean air and potentially thousands of jobs in America. Our nation needs to create its own renewable energy. The dependency on other countries is crippling our economy. Drilling for oil in the United States is not the answer. We need to take better care of our planet and that each of us must

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

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
