General Papers 15 December 2014 Energy According to Mother Nature Network‚ green energy comes from natural sources such as sunlight‚ wind‚ rain‚ tides‚ plants‚ algae and geothermal heat. These energy resources are renewable‚ meaning they ’re naturally replenished. There are many different types of green energy such as wind energy‚ solar energy‚ and hydroelectric energy. Each type of energy is very diverse in the way it affects our society. “Last year‚ wind energy added nearly half of all new power

CHAPTER-1 Q.12) How does a fall in the value of the pound sterling affect British consumers? ANS- A fall in the value of pound sterling affects the cost of foreign goods. Q.13) How does an increase in the value of the pound sterling affect Canadian businesses? ANS-An increase in the value of pound sterling results in Canadian dollar buying more units of foreign currency‚ which in turn results in appreciation. Q.14) Looking at Figure 1-8 (page 11)‚ in what years would you have chosen

GEOTHERMAL ENERGY Geothermal energy is one of the oldest sources of energy. It is simply using and reusing (reusable energy) heat from the inside of the earth. Most of the geothermal energy comes from magma‚ molten or partially molten rock. Which is why most geothermal resources come from regions where there are active volcanoes. Hot springs‚ geysers‚ pools of boiling mud‚ and fumaroles are the most easily exploited sources. The ancient Romans used hot springs to heat baths and homes‚ and

Oil & Gas Valuation – Quick Reference http://breakingintowallstreet.com Oil & Gas Valuation: Comparable Public Companies & Precedent Transactions Picking a set of comparable companies or precedent transactions for an oil & gas company is very similar to how you would pick them for any other company – here are the differences: 1. Rather than cutting the set by revenue or EBITDA‚ you would instead select the set based on Proved Reserves or Daily Production (in addition to the normal geographic and industry criteria)

The hypothesis about heat death of the universe Our knowledge of the universe is still negligible‚ and we can not confidently assert that the universe is not under the influence of external forces‚ or may be considered as a thermodynamic system. However‚ it is the concept of heat death was the first step to realize the possible finiteness of the Universe‚ although we do not know when and on what scenario will happen of its destruction. At the present stage of existence (13.72 billion years)‚

ow‚ what do mean by this? This means that conservation of a unit of energy is cheaper and environmentally more desirable than to generate an additional unit. For‚ it is estimated that generation of every additional kilowatt for one hour of energy requires an investment of Rs. 7‚000 to 12‚000 in the form of new energy generation equipments. Excessive utilization of coal and oil for generation of electricity leads to the multiple problems of acid rain‚ and rising carbon dioxide levels in the atmosphere

Renewable sources of energy Wind energy Wind Energy‚ energy contained in the force of the winds blowing across the earth’s surface. When harnessed‚ wind energy can be converted into mechanical energy for performing work such as pumping water‚ grinding grain‚ and milling lumber. By connecting a spinning rotor (an assembly of blades attached to a hub) to an electric generator‚ modern wind turbines convert wind energy‚ which turns the rotor‚ into electrical energy. Because wind is a clean and
