Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy technologies include solar heating, solar photovoltaics, solar thermal electricity, solar architecture and artificial photosynthesis, which can make considerable contributions to solving some of the most urgent energy problems the world now faces.
What is solar energy used today?
Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy.

Development of renewable energy is one of the most pressing tasks facing the global energy sector. In the foreseeable future, hydrocarbon fuel will retain its dominant position in the world energy balance, however the share of renewable energy sources will increase year by year. Despite the changing economic situation, depressions and crises, the demand for renewable energy is growing by the year.
Energy Supply, World
16 Апреля 2012 в 19:23, реферат
Energy Supply, World, combined resources by which the nations of the world attempt to meet their energy needs. Energy is the basis of industrial civilization; without energy, modern life would cease to exist. During the 1970s the world began a painful adjustment to the vulnerability of energy supplies. In the long run, conserving energy resources may provide the time needed to develop new sources of energy, such as hydrogen fuel cells, or to further develop alternative energy sources, such as solar energy and wind energy.

This increasing quantity of CO2 leads to the warming of our planet and becomes the main reason of the so-called Global Warming Effect. One of the ways to answer this challenge is to replace current technologies by alternative ones. They usually have comparable or better performance and at the same time they allow avoiding the usage of carbon dioxide. These sources are often called the Alternative energy.

In den Produktionsbetrieben und Werkstatten werden riesige Mengen von Energie gebraucht. Die Energie dient zum Antrieb der Arbeitsmaschinen, zum Heizen cler Ofen und Kessel, zur Beleuchtung der Arbeitsstatten. * Mechanische Energie, Warmeenergie und elektrische Energie sind fur die Technik die wichtigsten Energie--arten, Sie werden dem Energievorrat der Natur unmittelbar oder erst nach Umwandlung der erschlossenen Energieart entnommen. Die Energieteclinik soil die in den Energiequellen vorhandene Energie in Gebrauchsenergie umformen. Sie hat die Aufgabe, diese Energie nutzbar zu machen und neue Energiequellen zu erschlieBen.
