You can read the second post here. By Darshan Goswami, M.S., P.E.In the coming years, India will face seemingly insurmountable challenges to its economy, environment and energy security. To overcome these challenges, India needs to shift to non-polluting sources of energy.As Jeremy Rifkin, an economist and activist, said in New Delhi in January 2012: “India is the Saudi Arabia of renewable energy sources and, if properly utilized, India can realize its place in the world as a great power,” and adding “but political will is required for the eventual shift from fossil fuels to renewable energy.” The U.N. Intergovernmental Panel on Climate Change (IPCC) has also recommended that the world needs a major shift in investments from fossil fuels to renewable energy in order to curb greenhouse gas emissions and climate change.India has tremendous energy needs, and it is becoming increasingly difficult to meet those needs through traditional means of power generation. More than 40 percent of rural Indian households don’t have electricity. While India is developing domestic energy sources to satisfy the growing demand, it is also anxious about having to import increasing amounts of fossil fuels that exacerbate the trade deficit and can be harmful to the environment. Coal imports hit a record high during the last fiscal year and will likely rise further over the next five years since India aims to expand its power-generation capacity by 44 percent.The country’s inability to generate clean, affordable power is also a major constraint to achieving energy security. The present centralized model of power generation, transmission and distribution is growing more and more costly to maintain and, at the same time, restricts the flexibility required to meet growing energy demands. India needs to encourage a decentralized business model in order to more readily take advantage of abundantly available renewable energy sources like solar, wind, hydropower, biomass, biogas, geothermal and hydrogen energy, and fuel cells. India is blessed with an abundance of these resources, yet it spends millions of rupees to import oil, coal and natural gas — resulting in enormous amounts of renewable energy being unused/wasted. To that end, renewable resources are the most attractive investment, because they will also provide long-term economic growth for India.To secure its energy future, India urgently needs to design/implement innovative policies and mechanisms that promote increased use of abundant, sustainable, renewable resources. All of India’s future energy demand could be met by utility-scale and rooftop photovoltaics (PV), concentrating solar power (CSP), onshore and offshore wind, geothermal, and conventional hydropower. This would require building many more solar power systems and wind farms, hybrid solar-natural gas plants, solar thermal storage and advanced battery-based grid energy storage systems. Investment in these technologies would create millions of new jobs and an economic stimulus of at least US$1 trillion, and perhaps much more if all indirect (ripple) effects are included. Other major changes involve use of electric vehicles and the development of enhanced smart grids. Making the transition to 100 percent renewable energy is both possible and affordable, but requires political support.What needs to be done?Instead of an overarching energy strategy, India has a number of disparate policies. To date, India has developed a cluster of energy business models and policies that have obstructed adoption of renewable energy expansion plans. This present approach threatens India’s economic competitiveness, national security and the environment. India must fundamentally transform the manner in which it produces, distributes and consumes energy to reduce its dependence on foreign oil, create jobs, enhance global competitiveness and decrease carbon emissions.The government of India has taken several measurable steps toward improving infrastructure and power reliability (such as development of renewable energy from solar and wind), but clearly more needs to be done — and fast. One step in the right direction was the establishment of the Jawaharlal Nehru National Solar Mission (JNNSM) in late 2009. However, the present JNNSM target of producing 10 percent of the country’s energy from solar − 20 gigawatts by 2022 − is totally inadequate. JNNSM needs to take bolder steps, with the help of central and state governments, in order to play a greater role in realizing India’s solar energy potential. One such step would be establishment of a nationwide solar initiative to facilitate deployment of 100 million solar roofs and utility-scale generation installations within the next 20 years. In achieving such a goal, India could become a major player and international leader in solar energy for years to come.In addition, developing off-grid powered micro-grids have the potential to change the way communities generate and use energy, and can reduce costs, increase reliability and improve environmental performance. Micro-grids can be used to take substantial electrical load off the existing power grid and so reduce the need for building new or expanding existing transmission and distribution systems.Renewable energy potential in IndiaRenewable energy is the only technology that offers India the theoretical potential to service all its long term power requirements. The Indian subcontinent is blessed with abundant renewable energy resources. For instance, taking advantage of 300 to 330 sunny days a year, India could easily generate 5000 trillion kWh of solar energy, which is higher than India’s total yearly energy consumption. Even if a tenth of this potential was utilized, it could mark the end of India’s power problems. Using the country’s deserts and farm land, India could easily install around 1,000 GW of solar generation – equivalent to around four times the current peak power demand (India’s present generation capacity is about 210 GW).Wind energy can also help India convert to 100 percent renewable energy. According to the environmental group World Wide Fund for Nature (WWF), while India has no estimates of its offshore wind potential, up to 170 GW could be installed by 2050 along the of coastline. Hydropower could generate an estimated 148 GW, Geothermal around 10.7 GW and Tidal power about 15 GW. If these abundantly available resources were properly developed and utilized, all of India’s new energy production could be derived from renewable energy sources by 2030. In addition, all existing generation could be converted to renewable energy by 2050 while maintaining a reliable power supply in the interim. Barriers to implementing the renewable energy plan are seen to be primarily social and political, not technological or economic.In the next post in this series, Goswami will explore 10 strategies India can enact to go 100 percent renewable by 2050.

Thermal Solar (CSP) is not high-tech and does not need a new infrastructure.Replacing all its coal powered thermal generation plants by Solar Thermal could be done in 18 months concurrently at all of those locations. Building new Solar Thermal capacity could add new capacity concurrently and make India an all electric (powered by thermal solar) economy with in 5 years. The capital required is not beyond its capacity to raise, especially because, it will conserve its foreign reserves from expended on import of coal,gas and oil. Sir, I have a question how would we produce electricity in the rainy season because solar energy is totally dependent on Sun . Can we store the solar energy for around 10 to 12 days so that we can use that energy in the rainy season to produce electricity minm: Good question. There is a way to get around the need for storage by using interconnected smart grids. Since, there is sun shine elsewhere, 24 hours a day, by using smart-grids and interconnection among all CSP ( concentrated thermal-solar power) utilities, build around the equator for the entire planet, it is possible generate enough electric power from sun alone, to supply the entire needs of the global population. These global utilities and transmission lines could be made more efficient by using super conducting technologies available today. Storing energy for rainy season becomes unnecessary when we interconnect the transmission grids.There’s sun shine else where all the time. By combining data transmission with power transmission it becomes quite easy to replace all mater-to-energy conversion plants with solar energy utilities. Clean Energy has been underperforming the market, but its stock promises large upside which makes it a good buy for now on dips http://goo.gl/Wj62dg here it is mentioned that 5000 tri kwhr & 10 % of it Please let me know the PLF of these system. Are we able to harness all this energy completely. & What amount of land required for it. What is the status of current wind farms………….. Comments are closed.
