It is a kind of energy that do not dry up or run out of sorts, and indicate renamed it whenever nearing completion again exist, and have come from a natural resources, such as wind, water, sun, and the most important thing distinguishes it is clean and environmentally friendly energy, they do not have a particularly damaging gases such as CO carbon, nor adversely affect the surrounding environment, as they do not play a role in the level of impact temperatures. And renewable sources of energy is completely inconsistent with the non-renewable sources such as natural gas, and nuclear fuel where these sources lead to global warming, and the launch of carbon dioxide when used. Proceeding from the importance of renewable energy, appeared recently a new type of business under the name of renewable energy trade, and focused the bulk of its business to harness renewable energy sources, and use them to be a source of income-generating material benefit, and through the promotion, and despite what maligned him how the exploitation of renewable energy, from the high cost and the lack of mechanisms and techniques sufficiently, but there are a large number of countries that are preparing to start investment projects for renewable energy, taking care to draw the dimensions of this enterprise policies, and work on development and development. Renewable energy features a range of advantages of renewable energy, and makes them a unique source of energy, including: renewable energy is well located in all parts of the world. Renewable energy is environmentally friendly and clean. Reside permanently, and be renewable once again. Easy to use, depending on simple techniques and mechanisms. It characterized as very economical energy. It is an important factor in the environmental, and social development, and all fields. Help to create new jobs. Help to mitigate greenhouse gas emissions and thermal damage. Prevent harmful acidic precipitation. Limit waste in all its forms pool. Abandon plantings of chemical contaminants, and thus raise agricultural productivity. Use non-sophisticated techniques, and can be manufactured locally in developing countries.
