Sources of Sustainable Energy
The sources of sustainable energy are solar energy, wind energy, geothermal and nuclear energy. The energy source like solar energy present in abundance. It is the only natural resources which has no constraints in terms of availability, cost and ease of use. Solar energy is an inexhaustible energy source which never seems to end. Wind energy and tidal power are also the types of sustainable energy because the wind and tidal pressure does not seem to seize or end. However, the wind pressure is limited to the coastal regions so as the tidal power. Wind power is an environment friendly way of generating electricity. Sustainable energy sources are also known as green energy and alternative source of energy because of its environment attitude. Nuclear energy is also considered a sustainable energy sources because 90% of uranium can be used again to perform nuclear fission again and again. Therefore all those energy sources which can be used again and again without the fear of being diminished are parts of sustainable energy. Other important criteria of sustainable energy are its fuel efficacy. Nuclear energy is a really efficient source of sustainable energy.
The Need for Sustainable Energy
Until the beginning of nineteenth century the major energy sources were wood and timber. However later it was replaced with other natural resources like oil, gas and coal. The use of wood as an energy sources is a scarce resource it can not meet the energy requirement f large population. Moreover the concern for environment due the devastation of forests has increased the risk of global warming hence we need to grow more and more trees now. Fossil fuels like gas and oil are also getting scarce and the production of these resources is limited to the specific countries. The owners of the fossil fuels like coal, oil and natural gas also control their prices. Thus the need of the time was to search and look for the abundant natural resources which never seem to end. It is also important to look for the energy sources which are sustainable and efficient at the same time. Hence the need for sustainable energy resources like solar energy and wind energy has come to the surface.
The Energy Conservation
The energy sources like solar energy and wind power are present in abundance but it is important to conserve them in order to utilize them. Otherwise this abundant energy would go all in vein. It also important here to note that the electricity generated by using wind power and solar power need to be conserved and preserved. This is because that the solar energy is abundant but the cost of converting solar heat into electricity is an expensive process. Thus we do not have to focus entirely on the ways of producing power with sustainable energy sources but to look for conservation methods as well. The sustainable energy sources are becoming an attractive market worldwide. We can also use solar energy to conserve electricity by making our homes to utilize passive solar heating and cooling. Sustainable energy does need mean that we utilize the power and waste it. It is aimed at cutting down the energy costs and sustains the fuel crises.
