Caselet 1
This a truly a ambitious project and a showpiece of co-operation between the state Government of Rajasthan, the Government of India, the World Bank and the Government of Germany getting together to strike a blow to renewable energy.
The project in question is a 140 MW Integrated Solar Combined Cycle (ISCC) power plant with a solar component of 35 MW and a combined cycle power plant of 105 MW in Jodhpur district in Rajasthan. The combined cycle plant will use naphtha as the fuel, and a back-up plant of 35 MW will also lend a helping hand when the sun is not shining.
The total cost of the project works out to eight hundred and seventy-one crore rupees- a hefty capital cost of six crore thirty lakh rupees per MW while a stand-alone naphtha based plant will cost less than four crore rupees a MW. The trick here is how the project is being financed to make it viable.
• The Government of India will provide a grant of fifty crore rupees.
• The Government of Rajasthan will pitch in with an equity contribution of fifty crore rupees and a loan component of two hundred crore rupees.
• The World Bank through its Global Environment Facility will grant US dollars 49 million or two hundred and thirty-five crore rupees.
• The Government of Germany will add a “cheap” long-term loan of twenty-five crore Deutsche Marks or five hundred crore rupees.

Total “aid” in terms of grants and easy loan works out to close to one thousand crore rupees for an eight hundred and seventy-one crore rupee project!
Most of the time, the “green” and “clean” showcase project will be running on naphtha, a dirty oil based fuel, which negates all that green activists stand for. That is simply because the sunlight won’t be around at the convenience of green activists. Of course, economists would be more concerned with the opportunity cost of using one lakh seventy thousand tones each year of naphtha in this “solar” energy project!
Required
Q 1. How to Generate Solar Energy using Naptha? Explain?
Caselet 2
Energy plays a vital role in our day to day life. Energy consumption and production affect the local and global environment. Energy is mainly produced from fossil fuels and a sustainable development in the production of energy is a situation in which the future does not get harmed in any way. However, the use of fossil fuels will not help promote this much – longed – for sustainable development as fossil fuels when burned release a lot of energy into the atmosphere, which may lead to environmental damage.
The sustainable energy sources must be tapped to change the energy pattern used by the consumers, for which renewal energy sources like wind, sunlight and water need to be tapped and stored. The use of renewable energy is cleaner and safer for the environment. Various countries have started taking initiatives in building sustainable renewal energy resources, thereby, throwing open employment to the youth.
The adoption of renewable energy resources is difficult in poor countries due to lack of education, or inaccessibility of technology, or lack of institutional capacity for promoting renewable energy or lastly due to high financial costs. The environment of the youth can be roped in for the task of developing renewable resources after necessary coaching. Empowering the youth will help to reach a wider spectrum of the community in the development process of renewable energy resources.
The environment of the youth in such enterprises will tackle not only the issue of youth unemployment but will also promote environmentally sustainable renewable energy development. The rural youth need a conducive environment for the successful and continued implementation of renewable energy projects. In order to remote off –grid renewable energy, close and continuous engagement with local community members is essential. Thus, if the stakeholders are the ones who are developing and operating these enterprises, it will ensure viability, sustainability and effective operation in these enterprises.
The various renewable energy technologies available are not cost – effective and technically viable. However, most forms of renewable energy still have a significant way to go. The implementation of renewable energy projects can deliver clear benefits to developing countries provided they use efficient technologies. In this case, the technical know – how is invariably transferred from the experienced and developing countries to most of the less developed or developing countries.
Questions
Q 1. What is Renewable Energy and state the Sustainable Development to it?
Q2. How could renewable energy help in providing opportunities to the youth?
