The Search for New Sources of Energy

The environmental consequences of energy production have led many nations in the world to impose stricter guidelines on the production and consumption of energy. Further, the search for new sources of energy and more efficient means of employing energy has accelerated. The development of a viable nuclear fusion reactor is often cited as a possible solution to our energy problems. Presently, nuclear-energy plants use nuclear fission, which requires scarce and expensive fuels and produces potentially dangerous wastes. The fuel problem has been partly helped by the development of breeder reactors, which produce more nuclear fuel than they consume, but the long-term hopes for nuclear energy rest on the development of controlled sources using nuclear fusion rather than fission. The basic fuels for fusion are extremely plentiful (e.g., hydrogen, from water) and the end products are relatively safe. The basic problem, which is expected to take decades to solve, is in containing the fuels at the extremely high temperatures necessary to initiate and sustain nuclear fusion.Another source of energy is solar energy. The earth receives huge amounts of energy every day from the sun, but the problem has been harnessing this energy so that it is available at the appropriate time and in the appropriate form. For example, solar energy is received only during the daylight hours, but more heat and electricity for lighting are needed at night. Despite technological advances in photovoltaic cells, solar energy has not become a more significantly more financially competitive source of energy. Although several solar thermal power plants are now in operation in California, they are not yet able to compete with conventional power plants on an economic basis.

поиск новых источников энергии

экологические последствия производства энергии привели к тому, что многие страны мира принимать более строгие руководящие принципы в отношении производства и потребления энергии.кроме того, поиск новых источников энергии и более эффективные способы, используя энергию ускорился.развитие жизнеспособной ядерного синтеза реактор часто упоминается в качестве возможного решения наших энергетических проблем.в настоящее время ядерных электростанций использования ядерного деления, который требует ограниченных и дорогостоящих видов топлива и производит потенциально опасных отходов.топливо проблему удалось частично способствовала развитию реакторах - размножителях, которые производят более ядерного топлива, чем они потребляют,но долгосрочные надежды на отдых на развитие ядерной энергии, контролируемых источников с использованием ядерного синтеза, а не деления.основные виды топлива для синтеза очень много (например, водород из воды) и конечной продукции, являются относительно безопасной.основная проблема, которая, как ожидается, потребуются десятилетия, чтобы решить,
