• Solar energy: Solar energy means using the energy of sunlight to provide electricity, to heat water, and to heat or cool homes, businesses or industry. Photovoltaic (PV) solar cells directly convert sunlight into electricity. The simplest cells are used to operate hand clocks and calculators, and more complicated systems are used to light houses

  • Wind energy: Wind power is the conversion of wind energy into a useful form of energy. Blowing wind spins the blades on a wind turbine – just like a large toy. Through different systems the energy of the wind turbine, turns into electric energy. This type of energy is very common in Holland.

  • Waterpower: The power of this energy derived from the force or energy of moving water. This can spin watermills and produce electric energy. For example, there is a dam in San Juan in Ullum which can give energy to all the province. The most important thing is that this energy is renowable and does not pollute the environment.

  1. Biodiesel :Biodiesel is meant to be used in standard diesel engines and is thus distinct from vegetable and rubbish oils used to fuel converted diesel engines. Biodiesel can be used alone, or blended with petrodiesel. Biodiesel can also be used as a low carbon alternative to heating oil.There is a discussion bettwen people who are in favor of biodiesel and those who are not.

  • Green cars: Nowadays, one of the main problems that scientists and society discuss every day is the environment and pollution of it. Some scientists made studies about pollution on Earth and they came to the conclusion that in a short period of time we will be able to notice catastrophic changes on Earth’s environment and surface. To clear this problem, or at least, to turn it less harmful some associations and organizations have been organizing some campaigns. The goal of this kind of campaigns is to decrease pollution levels and to improve the environment and life conditions on earth.

  • Renewable Energy

It is called renewable energy to the energy obtained virtually inexhaustible by natural sources, some of the vast amount of energy they contain, and others because they are able to regenerate by natural means.


  • Green energy are non-polluting renewable energy, that is, whose method of production or use products issues that might affect the environment.

They are currently gaining importance due to the worsening of the greenhouse effectand consequent global warming, accompanied by an increased awareness worldwide about the problem. Also, economies that do not possess or exhausted their traditional sources of energy (including oil or gas) and need to acquire these resources from other economies that seek to avoid energy dependence and the negative trade balance that this acquisition represents.
