World energy consumption World energy consumption in 2010: over 5% growth [6] Energy markets have combined crisis recovery and strong industry dynamism . Energy consumption in the G20 soared by more than 5% in 2010‚ after the slight decrease of 2009. This strong increase is the result of two converging trends. Onthe one-hand‚ industrialized countries‚ which experienced sharp decreases in energy demand in 2009‚ recovered firmly in 2010‚ almost coming back to historical trends. Oil‚ gas‚ coal‚ and

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

INTRODUCTION: ENERGY FROM THE SUN The sun has produced energy for billions of years. Solar energy is the sun’s rays (solar radiation) that reach the earth. Solar energy can be converted into other forms of energy‚ such as heat and electricity. In the 1830s‚ the British astronomer John Herschel used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today‚ people use the sun’s energy for lots of things. Solar energy can be converted

The European Union Energy Policy: An Initiative in Progress Anna Rulska April 2006 I. Introduction In January 2006‚ Russia cut off supply of gas to Ukraine. The European Union (EU)‚ dependent on gas from Russia‚ delivered through Ukraine‚ realized the full extent of its vulnerability in the realm of energy security and a need‚ more pressing now than ever‚ for a common energy policy. Shortages of energy carry implications not only for domestic producers and consumers‚ but also for

Abstract: Solar energy is quite simply the energy produced directly from the sun and collected elsewhere‚ namely the Earth. Photovoltaic technology directly converts solar energy into electricity. Photovoltaic thin film solar cells are easy to handle ‚ inexpensive and also easy to use. Thin film panel is flexible and can tolerate a bullet hole without failing and can greatly increase the surface area and the absorption coefficient needed to generate electricity. This paper will discuss the advantages
