How to produce electricity has traditionally
Electrical energy production is one of the inescapable needs of every developed country and one of the most polluting. The biggest problem is that electricity can not be stored, and therefore must produce at the same time it is consumed.
Although there are other ways of producing electricity in industrial production is based on a single technology: can we turn a turbine connected to a generator. But to move the turbine requires a primary energy source. There are two basic ways to produce electricity, hydro power and thermal power.
Hydroelectric production consists of passing large amounts of water at high pressure through a turbine. Is a technology that requires a major intervention in space, because you need large quantities of water dam and have significant slopes. Has the advantage that it is a renewable primary energy and produces no emissions into the atmosphere. However, the precise conditions are not everywhere, so the total production depends on terrain and rainfall conditions. In addition, his great contribution is the impound of water produces significant changes in the environment, and adjust the next ecosystem. Technological advances in improving the efficiency of the turbines, allowing the creation of micro, which require much less infrastructure. Currently a small hydroelectric plant does not need more infrastructure than the old water mills. Thus, the landscape of the riverbanks, villages and cities, is filled with these mini.
Thermoelectric production involves passing hot air under pressure through a turbine. The hot air is obtained by boiling water and this water there are two technologies: the burning and nuclear fission. Plants that heat water are called burning power plants. Can use four types of fuel: bastard, oil, gas or biofuel.
1 .- The burning of coal is expensive, efficient and highly polluting. In addition to the CO2 emitted into the atmosphere other very harmful compounds such as sulfur. Is a non-renewable fossil resource.
2 .- The burning of oil is expensive, very effective and very clean. Generates a lot of CO2 that is released into the atmosphere. The oil that is burned in power needs to be refined, so that there is an intermediate industrial process also consumes energy and produces pollution. Is a non-renewable fossil resource.
Spain became a leader in solar energy
China, which enjoys an incredible global financial assets that ranked as the world’s second largest economy. Or in continental terms, European is what develops further action and investment in clean energy. However, even in crisis, Spain has managed to sign up as a reference in the matter, because today is a leader in solar energy.
After a hard work and by good growth policies, Spain surpassed the United States became the world’s largest producer of solar thermal energy, creating an installed capacity of 432 megawatts (MW), 10 more than Americans.
The achievement was made possible due to the thermal plant “Florida” in Badajoz, most other plants that produce record capability on the mainland. Among all plants make up a territory in excess of 550,000 square meters to capture solar energy has been become the largest in the world among the plants in operation.
Inevitably, the world’s leading nations have begun to invest and set plans in renewable energy. The oil reserves are not eternal and an estimated remaining oil for thirty years at peak production and then begins to decrease. That is why new renewable energy sources are the main stake in Spain, has started positively.
The solar energy is produced through the use of the sun’s energy for heat and for the production of mechanical energy and then electric.
The energy efficiency for the sake of continuity in the future
The growing global concern about the future of our planet has established an important point about the questioning of current patterns of energy production and consumption.
The challenge to this pattern is mainly due to energy resources are limited and found in certain parts of the world, to use this current pattern is causing serious health effects on humans and the environment.
Thus, nowadays we need to ensure energy security, we need to control pollution caused by burning fuels and minimize the greenhouse effect caused by the emission of atmospheric gases [GHG]. Every day we damage our climate by using fossil fuels (oil, gas and coal) in transport, industry and produce electricity. Power generation from these fuels generate 61% of worldwide total of greenhouse gases.
In addition, there are other challenges that have become urgent. World energy demand is growing at a rapid pace. Not only countries like China are increasingly demanding more energy. Over-reliance on energy imports from a few countries, generating instability and insecurity in the supply and prices of oil and gas steadily increasing have placed energy security as a concern in the political agendas of governments worldwide.
Climate change is already affecting our lives and is expected to destroy the livelihood of many people in developing countries, many ecosystems and species in the coming decades. For this reason we must drastically reduce our GHG emissions, an important measure both from the standpoint of environmental, social and economic.
It was found that the average global temperature has been increased during the twentieth century of 0.6 + – 0.2 ° C, plus there is a real reduction in arctic ice cover and increased the frequency and intensity of so-called natural disasters such as hurricanes, droughts and torrential rains. According to the Intergovernmental Panel on Climate Change, (IPCC), the forum of experts from the United Nations, is expected to increase in global temperature over the next 100 years of 5.8 ° Celsius, an increase much faster than experienced so now in the history of mankind. Facing this situation there is a growing consensus not to exceed 2 ° C increase in global temperature over pre-industrial era. To an increase of 2 ° C and above will be a dramatic increase in damage to ecosystems resulting social and natural disasters.
Plans fiber important role of forests for Environmental
This one of the characteristic features of the landscape of Navarre. The mountains, which occupy two-thirds Navarra planning, contribute significantly to the maintenance of biodiversity while protecting and maintaining much of the agriculture and livestock.
To optimize the level of the mountains of Navarre is necessary to join efforts to properly plan and social forestry.
Provincial government with the participation of all sectors involved has proposed a model of action for the coming years with a long-term policy lines that constitute the Forest Plan Navarra.
Navarra Forest Plan is based on six criteria:
* Intergenerational Equilibrium: that future generations can also enjoy the mountains.
* Balance between generations: development from their own resources; society access to forest goods and services, and support for owners for the maintenance of social and ecological functions.
* Use multiple rational and integral management of all forest functions: biological, environmental, economic and social.
* Increased efficiency, economic growth based on: efficient use of existing forest resources; and development of new resources.
* Integration of forests and society to establish a profound and respectful relationship between them.
* Subsidiary: local authorities should act as protagonists.
Specifically, the objectives posed by the Forest Plan are eight: increased quality and quantity of forests, protection of biodiversity and quality of forest resources, forest protection against natural hazards and human sustainable protection of economic assets ; adapting to the demands of societal uses, a forest industry competitiveness stabilizing employment, increase in management activities of forest stakeholders, and development and livelihood improvement and management techniques.
Find information about the nuclear through some places
The majority of waste generated from nuclear applications, but few know what the real result that produces the accumulation of such waste on the planet, and even exist in most countries, certain regulations for handling such waste, are not fully met. On the other hand, we should mention the site or where to find more information forms of nuclear energy, which generally tend to be nuclear plants, since the processes are carried out to obtain this type of energy are extremely complex and to achieve understanding themselves should have some basic knowledge and not so basic chemistry and related sciences.
To begin, we can say that certain books or manuals which includes all information of this type, including also the formulas with the elements, the reactors and the products of each reaction is carried out to obtain nuclear energy, and although we all know that books are the most reliable sources of information, accurate and complete we can find, while not as simple to find books that contain such information.
That is why you can always go to a Web search, although many argue that the web is not always a reliable source of information, there are certain places where you can find exactly the information sought. Anyway, it is important to note that to find information on the Internet should be able to look properly, and make some sense or experience to recognize those pages that are trusted and those that are not.
That is why it is recommended that information should be sought nuclear energy needs, complete and extensive use is made directly to books and manuals can be found in libraries of all types, whether by commission or directly to the sale. If nuclear power sought information less complex, to obtain a basic understanding of the procurement of energy can always resort to the Internet, as well as a public library where if you are a member, or often it is not necessary that condition, you can find all the books and is always required some assistance in finding exactly what you find and make use of the book until it has obtained the necessary information.
How energy use is not Excessive
All nutrients are absorbed from the gastrointestinal tract into the blood has the fundamental aim to provide the body enough energy so you can make, the more efficiently and with the least possible cost, all its functions and also to provide the material needed to be establishing themselves replacing losses occurring during the development of these functions.
The man and the higher animals (heterogeneity organisms) get this energy through a process of oxidation of nutrients that are ingested through food. However, the cells for energy cannot use such substances directly, since cellular energy production relies almost entirely on a molecule called adenoid tropospheric, or ATP, which is synthesized from the above nutrients above.
The ATP has three phosphoric acid molecules which are linked together, these links are also easy to break and release large quantities of energy that will be used by all body cells. When a cell needs energy for any function, through a process of hydrolysis is separated from the tip of the ATP molecule of phosphate joints, causing a large release of energy (approximately 7,300 calories).
As a result of this reaction is a new compound with two molecules of phosphoric acid, adenoidal diphtheria or ADP, which, through a reversible reaction, then will join a new molecule of phosphoric acid, which is obtained, again, another ATP molecule.
As shown, the cells, through complex biochemical processes, are able to transform the potential energy in food in the diet in other types of energy needed to carry out its functions, such as kinetic energy development of motor activities, the thermal energy to trying to regulate its temperature, or electrical energy, which is to be used in conducting nerve impulses.

How The impact of Nuclear energy on the environment
Not everyone knows what are the exact characteristics of this type of energy production, and taking into account the influences to their use in the environment, as well as disadvantages they can be found in other aspects is always desirable to have a certain amount of information on nuclear power for so long be made aware of important issues such as the environment and the different forms of energy production, although not appears to directly influence the life of each in a consistent manner.
To begin with the information of nuclear energy should begin with the main features. This type of energy is obtained or released in a spontaneous way by different nuclear reactions, also called nuclear processes. It is very important to provide some basic information about nuclear reactions when talking about nuclear energy information. Information-energy-nuclear reactions are processes of transformation and combination of subatomic particles and nuclei, and can be both endothermic and exothermic, depending on whether the use or release energy.
The first, i.e. the endothermic are those that use energy to achieve them, and the opposite happens with the exothermic, when they occur, they release a certain amount of energy. It is also necessary to mention that they may consider nuclear power for example electric power purchased from a nuclear way, i.e. through nuclear reactions. As well as thermal energy can be obtained by these reactions, or any other type of energy. There are two ways to obtain nuclear energy, those that are through nuclear fusion, and they are using nuclear fission.
To begin with, nuclear fission occurs when the nucleus of an atom splits into two or more parties, and of course this is an exothermic reaction because it releases energy. On the other hand, nuclear fusion reactions are characterized gather a release energy of nuclei of atoms of similar charge and form a heavier nucleus and as explained above reaction also releases a certain amount of energy is therefore an exothermic process. On the other hand, there is some aspect of nuclear energy information which is not commonly spoken and is the same impact on the environment.
Control the environment and ensuring energy security
