Abstract
Renewable energy systems can provide clean, reliable, secure and competitive energy products and services to help meet the rapidly increasing global energy demand. In a carbon-constrained world of the future, renewable energy sources with zero net greenhouse gas emissions will have an increasingly important role to play. Being widely distributed, renewable energy sources have the potential to provide electric power, …show more content…
• Do not contain any pollution to the environment.
• Can the existing in land use in farming as the fields.
• It is possible to use mills (small size are placed on top of buildings generators).
Disadvantage:
• Causing noises because of the high voice during the rotation. Wind turbines rely on the movement of rotor affected by wind to rotate the generator and make electricity and generally quiet in operation and compared to noise of road traffic
• the most popular case, kill some birds that collide during flight affected by voltage overhead line.
• Wind energy cannot be stored (unless batteries are used).
• Depending on how active wind site, since it requires specific conditions.
3-Hydroelectric energy:
This form uses the gravitational potential of elevated water that was lifted from the oceans by sunlight. It is not strictly speaking renewable since all reservoirs eventually fill up and require very expensive excavation to become useful again. At this time, most of the available locations for hydroelectric dams are already used in the developed world.

If renewable energy is to reach its full socio-economic potential and achieve significant greenhouse gas mitigation benefits, considerable further investment in R, D & D and international cooperation will be necessary. The various IEA Implementing Agreements relating to Renewable Energy and Hydrogen and various other international agencies have served a useful role in encouraging international collaboration over the past 2 to 3 decades. More co-operation is underway following on from the World Summit of Sustainable Development held in 2002 in Johannesburg. Methods now need to be found to support these activities and to expand the involvement of developing countries. Since many renewable energy technologies are applicable to developing countries hoping to improve their energy supply systems and infrastructures, then it is imperative that such collaboration is expanded to somehow include them. Cooperation with UNDP (United Nations Development Programme) and similar international organizations could be one way forward to deliver sustainable energy systems to the
