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

renewable energy and this energy is abundantly available in all parts of the earth. It is in fact one of the best alternatives to the non-renewable sources of energy. Solar energy has been used since prehistoric times‚ but in a most primitive manner. Before 1970‚ some research and development was carried out in a few countries to exploit solar energy more efficiently‚ but most of this work remained mainly academic . After the dramatic rise in oil prices in the 1970s‚ several countries began to formulate

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

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

India is in this region of the world. Hence cyclones often blow over her. In cold countries there is no cyclone. The signs of a cyclone There are some signs of the blowing of a cyclone. A low pressure is created in the sea. The weather becomes very hot. There is not a breath of wind. Patches of dark clouds gradually spread in the sky
