INTRODUCTION In concept, energy is the ability to work or something. There are different types of energy such as heat, sound, motion, light, and so on. There is a very high probability of these kubadilinishati from one type to another using various techniques and materials. In this paper I will comment very briefly to light and heat energy. THE IMPORTANCE OF ENERGY For a simple explanation is that there is no life without energy. pgpr emulsifier Energy is the source of our life, as light as the energy of the sun helps us to see and do different things, brings us vitamin D and this helps fuel synthesis plant food, which we are dependent for our food. Energy of motion helps us to move from place to place for a very short time with today's technology and helps heat energy for various things such as cooking our food, drying pgpr emulsifier crops, pgpr emulsifier adjusting domestic air conditioning and so on. There has been a renaissance different pgpr emulsifier place in the world about the future of the world especially in the sensitive issue of energy. Often the world has been depending on plants, mining (coal and nuclear) and oil as energy sources diversification. Firewood and charcoal in the plants we find firewood and charcoal for a country like Tanzania which makes up more than ninety percent of all the energy needs of the nation. This is a very large scale, so a conscious effort should be to reduce this amount. Firewood pgpr emulsifier and charcoal are used everywhere in the developing countries in various work, from domestic to industrial. pgpr emulsifier Wood is used to produce heat energy in tea and tobacco industries, it kicks domestic cooking and many other applications only. In developed countries the wood is used to heat water, which is circulated homes for special pipes for generating heat in the winter. It is highly energy dependence of these countries especially in the winter, to be using power plants generate heat is somewhat expensive. Coal Coal for previous years were used directly manufactured produce heat energy and motion pgpr emulsifier for different uses. Until now there are several places in the world where coal is used to produce pgpr emulsifier energy (such as coal mine in the tilling / KiwiraMbeya). pgpr emulsifier Coal is also used in the cement industry in producing high temperature refining stones to yasagwe to produce cement. But due to climate pollution, coal not seem to be environmentally pgpr emulsifier friendly fuels us, so kukafanyika very significant changes to the energy leaving many areas. But there are still many countries pgpr emulsifier that do not zijaiacha only this energy, including the country of China that comes up in global industrial development. Direction and emphasis of society became in petroleum oil which now takes on a very large human life. Fuel oil is used to run these plants as well as how far away the lightning izalishayo, famous as a generator. Vehicles, aircraft, ships, some trains run to this energy as well. With time, energy and it proved not environmentally friendly as used in environments that are not appropriate. Smoke caused by this oil is used in installations are very effect on the environment, to be added vast amounts of carbon dioxide in the atmosphere and destroy ozone membrane. The result is that there is a warming in the face of the earth, and this increase has posed a lot of impact pgpr emulsifier in different areas in the world (I shaliongelea this in previous topics). That is one, but the second is that if an accident occurs marine and vessel kinachosafirisha kikahusika oil, the oil will not stay in the water (and oil usually floats in water), and effects on organisms living pgpr emulsifier in the water. For creatures like fish, are unable to breathe air that prevents oil from getting into the water. In living birds to rely on fishing, this oil was wapakaapo their fishing activities are unable to fly since their wings are connected to the muscle it sometimes dies. At present there are strategies for developed countries, to abandon this energy dependence, but it would take too much time, though most likely (See previous article). WATER For many years the power of water has been used in various ways. In terms of energy, water has been used to directly drive mechanical grinding corn, and in the case of Tanzania, this system still works until now. For example, in the village of Muheza district in Tanga Islander, there is a grain mill plant which is operated by power
