  • With shortages of fossil energy and heavy biomass energy use occurring in both developed and developing countries, a major focus has developed worldwide on renewable energy systems. Currently, a heavy focus is on biofuels made from crops, crop residues and wood. Though it may seem beneficial to use renewable plant materials for biofuel, their use raises many concerns about major environmental problems, including food shortages and serious destruction of vital soil resources.

  • As populations increase and countries industrialize, the world’s demand for energy increases. Our supply of petroleum and gas is limited, but the photovoltaic cell offers a solution to the problem of a future energy shortage. This cell is already an important source of energy. In fact, it seems almost like magic. The photovoltaic cell changes sunlight directly into energy. Solar energy – energy from the sun – is clean, easily available, inexhaustible, and free, if the equipment is available....

  • Wind energy is one of the most prominent renewable energy sources today. The increasing concerns with environmental issues are driving the search for more sustainable electrical sources. Wind energy along with solar energy, biomass and wave energy are possible solutions for environmentally friendly energy production. The initialization of wind power installation, which started in the beginning of 1980s, is very much related to the oil crises of the mid 1970s.

  • Introduction: On 23 March 1989, electrochemists M. Fleischmann and S. Pons claimed in a press conference at the University of Utah that they had achieved nuclear fusion in a tabletop chemistry experiment. Since then, evidence of fusion in what is now called low-energy nuclear reaction (LENR) research has grown only slightly stronger. Their hypothesis that a novel form of thermonuclear fusion was responsible for their experimental results is still unproved.

  • Global warming resulting from the use of fossil fuels is threatening the environment and energy efficiency is one of the most important ways to reduce this threat. Industry, transport and buildings are all high energy-using sectors in the world and even in the most technologically optimistic perspectives energy use is projected to increase in the next 50 years. How and when energy is used determines society’s ability to create long-term sustainable energy systems.

  • Energy is important for the existence and development of humankind and is a key issue in international politics, the economy, military preparedness, and diplomacy. To reduce the impact of conventional energy sources on the environment, much attention should be paid to the development of new energy and renewable energy resources. Solar energy, which is environment friendly, is renewable and can serve as a sustainable energy source. Hence, it will certainly become an important part of the future energy structure with the increasingly drying up of the terrestrial fossil fuel.
