To waste, to destroy our natural resources, to skin and exhaust the land instead of using it so as to increase its usefulness, will result in undermining in the days of our children the very prosperity which we ought by right to hand down to them amplified and developed.”
― Theodore Roosevelt.

Renewable energy sources are derived directly from Nature and as the name suggests is not depleted or destroyed with use. The most commonly used sources are Sun, wind, hydropower, biomass and bio-fuels and the dependence on these sources will enable energy security, climate change mitigation and a secure economy. The development of the Renewable Energy market at the International and National level is expected to grow in the coming decades as Nations all over the world are aware of the dangers to the climate and environment if fossil fuels continue to be the mainstay of the Energy Sector.
The current strategy followed by nations all over the world is to depend on Renewable Energy sources to have a clean and sustainable development path. The Indian government is keen on encouraging the production and use of Renewable energy sources in order to reduce dependence on fossil fuels and reduce emissions of carbon dioxide. The path that India will take is extremely important to the world at large firstly as it is set to surpass China to become the world’s most populated country by 2025 with a population of 1.45 billion people and secondly in its World Economic Outlook Update released, IMF retained India’s growth projection for current year at 7.5 per cent, which will be higher than China’s 6.8 per cent. It forecast’s a growth rate of 7.5 per cent for India in 2016 as well, as against China’s 6.3 per cent. Therefore this transition to depend more on Renewable will solve the twin fold challenge faced by India namely maintaining an emerging economy with lowered carbon emissions.
India’s economy would grow roughly sevenfold by 2030 compared with 2005 levels, while its carbon emissions would triple if India took no initiatives to contain.
The Renewable Energy Project here at Jyoti Nivas College was initiated and streamlined under the able guidance of our Principal Dr. Sister Elizabeth CS This project was commissioned on the 26th of May 2016, thereby establishing the capability of the college in initiating collaborative research work with CSIR-NAL as per the memorandum of understanding signed by the two institutes.
Jyoti Nivas College has the unique advantage of being the first Science College in Bangalore to have a Wind Turbine installed in the campus. It aims at synchronizing electricity produced from Renewable Sources such as Solar and Wind with conventional power sources. Renewable Energy is an alternate means to fossil fuels and rising green Energy supplies can make deep cuts in fossil fuels thereby reducing the global warming as well as reducing the expenditure required in using fossil fuels.
This turbine is designed for superior performance for even low speed Indian wind regions. It has a state of the art light weight rotor with advanced aerodynamic design and eco-friendly composite blades and it uses a Horizontal axis upwind with 4 blades. The blade material is CFRP and the power rating is 900w at the sea level air density .The operating wind speed is about 3-18m/s and the rated wind speed is 12m/s. The diameter of the rotor is 2.15m and uses tail vane for directional control. The tower height of the turbine is about 25m.
The main limitation of a standalone wind turbine happens to be the relatively few hours of their productive operation in a day .The key hindrances to Renewable Energy Sources are that it is diffuse, low density energy resources which require systems for concentration and storage thereby making it slightly expensive. Renewable energy sources could be used as mainstream and fossil fuels on the other hand could be used as a backup if few of these disadvantages can be remedied .The transition to Renewable would also eliminate external costs associated with air pollution and climate change. The areas that need to be strengthened with regard to Renewable Energy are the storage facility. The policy makers are planning to impose Carbon Tax so that the dependence on Renewable will be enhanced further. In the long run , the government policy to have roof top solar panels may prove to defeat the purpose for which it is made when the solar panel loses its efficiency and requires a safe method of disposal. The rapid developments in green energy technologies will pave the way to reducing the carbon dioxide emissions thereby protecting the ecosystems and also paving the way for an Energy secure future.
