Now a day with the increasing demand of population and energy we must take a renewable option of energy source and also we must keep in mind that energy should not cause pollution and other natural hazards. In this case, solar energy is the best option for us. India is a very populous country, so we must take advantage of that energy that requires a much lower space to produce energy efficiently. In this case the solar tree could be the best for us. You can also use the technique called "SPIRALLING PHYLLATAXY" to improve the efficiency of the plant. It can be applied in street lightening system, industrial power supply etc. It is much better than the traditional solar photovoltaic system in point of view area and also more efficient. So this will be a very good option and should be implemented.
It is a form of renewable energy resource that is some measure competitive with fossil fuels. Hydropower is the energy of moving water energy. It provides about 96% of renewable energy in the United State. Hydroelectric plants do not use resources to generate electricity or do not pollute the air. The sun is a hydrodynamic spherical body of extremely hot ionized gases (plasma), generating energy by the process of thermonuclear fusion. The temperature of the interior of the sun is estimated at 8 * 10 ^ 6 k at 40 * 10 ^ 6 k, where the energy is released by the fusion of hydrogen and helium. Solar energy is available in abundance and is considered as the easiest and cleanest way to take advantage of renewable energy. For direct conversion of solar radiation into usable form, the routes are: solar thermal, solar photovoltaic and solar. However, the main problem associated with taking solar energy is the requirement to install large solar collectors requires a very large space.
