HOW TO SOLVE THE PROBLEM OF ENERGY SHORTAGES IN THE WORLD?

With the growth of nations is occurring not only in terms of population, but also economic, energy consumption has also increased and has become a problem for engineers and scientists worldwide.

Today it takes about 14 terawatt / year to supply homes and notorious economy on the globe. The problem happens because much of this energy is supplied by non-renewable sources such as coal, oil and natural gas.Another factor of major importance in this situation is bad energy distribution. It is evident that the less economically developed areas do not have the same availability of energy that other developed countries. According to the World Bank's director, Juan Jose Daboub, "in Uganda, only 5% of the population has electricity." All this energy inefficiency creates the feeling that energy is scarce in the world.We can not forget that in any way increase the extraction of energy from these sources, has caused a significant increase in pollution in the world. And now there are just calculations, charts and research institutes and NGOs to raise the banner of protecting the environment. But we have felt the skin growth.Examples include lower rainfall or more often in the form of these acidic, harming agriculture. Rising sea levels causing problems in the construction of cities. There has been a substantial increase of disasters on the globe. They are identified by scientists as a result of rising global temperatures, caused almost entirely by burning fossil fuels in the pursuit of energy, causing the greenhouse effect, which may even eradicate the planet.The solutions to this problem are being put into practice. Half timidly by governments, but it can be seen and felt. The main one is the use of renewable and clean energy. Whether in the form of solar, wind, thermal or biomass, which really matters is that these sources right away to solve two main problems mentioned here: scarcity and pollution. And on top of technology to generate more research and developing countries, and also posts job.Against these energy sources account for only the price factor.Well, to explore them all with high efficacy depends on investments. According to research by MIT (Massachusetts Institute of Technology), to install and use a field of wind energy to generate electricity for a city of 50,000 inhabitants is required on average an initial investment of 20 million dollars.We must decide what is best for our lives and for our descendants. Save money and still end up losing over energy, sacrificing jobs and lives? Or spend more money and save the environment, using its resources wisely and sustainably, maintaining life on earth possible? The choice is ours.
