Action Plan to Increase Renewable Energy



The Union Minister of New and Renewable Energy, Dr. Farooq Abdulla, informed the Rajya Sabha in a written reply that the Ministry of New and Renewable Energy (MNRE) has formulated a Plan for increased exploitation of various renewable energy sources in the country during the 12th Plan period. The Jawaharlal Nehru National Solar Mission has been initiated with a view to increase utilization of solar energy in the country.

The 12th Plan proposals envisage 29,800 MW grid-interactive and 3267 MW off-grid power generation capacity addition from various renewable energy sources and deployment of 7 lakh biogas plants, 35 lakh cook stoves, 8.5 lakh solar cookers and 80.5 lakh solar thermal energy systems in the country during the plan period. Besides, stepped up support for sector specific resource assessment and R&D activities, etc. Under the Jawaharlal Nehru National Solar Mission, deployment of 20,000 MW of grid-interactive solar power, 2000 MW off-grid applications, including 20 million solar lighting systems and 20 million sq. solar thermal collector area is envisaged by 2022.

The Minister further said that such systems are to be developed and put in place by respective State and District level authorities taking into account their existing electricity demand, available supply options and resources and other local factors.

  2. Ocean tides are an unlimited source of energy which has been made use by man for hundreds and hundreds of years since the invention of the wheel. At one time of our history, tidal mills could be seen on many sea shores. They made use of high tide and low tide well. Incoming tide will be trapped into reservoirs through sluices, which while coming in with great force will pass through propelling water wheels creating turning power which in turn will produce useful power. The coming n tides build up against the dam until there is a difference of at least 5 ft between one side and the other and will not allowed leaving by closing the sluice valves. When the tides are low, the sluice valves are reversed, allowing the water to flow out forcefully, again passing through the turbines a second time in their return journey. When it is high tide again, the valves and the turbine blades are again reversed and the cycle repeats. The difference in the level of water between one side and the other of the dam is called the ‘head’ of water and the higher this head the more electricity will it produce. A higher column of water will be under greater pressure which when released will turn the turbines more forcefully. A tidal wave installation in Nova Scotia has the highest ‘head’ in the world, a water level difference of 59 ft. The sluices and turbine blades in this kind of power generating installations can be used in either direction, making optimum use of movements of the entrapped sea water. Water remaining in the dam will be pumped out using electricity which will more than be made up in the process. Luckily the world is gifted with unbelievable stretches of shorelines and inexhaustible source of tidal waves. Cost of building the dams is the only deterring thing which has not deterred many nations including the Canadians and the Russians. If this unlimited source of energy was trapped and used with foresight, the world would not need thermal, fossil, nuclear or solar energy. Tamil Nadu has a very long coastline. Why didn’t consider it earlier? Chief Ministers and Prime Ministers are paid great salaries for thinking ahead of ordinary people and envisioning things in advance. Or would they say the Arabian Sea and the Indian Ocean have not enough water and waves to service Tamil Nadu and Kerala?

  3. Everyone knows that the earth’s temperature is the least in the outer crust and the most in the central core. Radioactive materials in the earth’s inner core decay continuously, and the nuclear reactions caused by these reactions heat up the inner portions of the earth’s crust up to 4000 degrees centigrade. This immense heat diffuses to the higher layers of soil, rocks and clay and superheats the water in underground streams and rivers flowing through them, resulting in hot water geysers, streams and steam up ground. As early as in the first decade of the 20th century, man built geothermal stations to tap this steam, bring it to turbines, run his generators and produce electricity. In many parts of the world, rocks situated beneath the upper crest of the earth, at just 6500 ft depth, are nearly 260 degrees centigrade hot. The heat latent in these rocks can be made use of in two ways. Either we can directly tap the hot steam, stream or geyser coming out of the earth to our turbans or we can drill these hot rocky layers, pump water in and take steam out through two separate holes. Why the underground water and the pumped in water do not boil and become steam in spite of its temperature of nearly 200 degrees centigrade is because of the high pressure in those depths. But once this superheated water is released from this high pressure and comes out into the atmospheric pressure, it instantly becomes steam and can be used as such. That is the attraction for geothermal power. Earlier there was the problem of the water pumped into the bowels of the earth not coming back but escaping into subterranean pools, lakes, rivers or even canyons which have never been exposed to sunlight since their formation. There also was the problem of removing minerals from the out coming water to prevent pipes and turbines corroding. Now such problems have been successfully solved. The only problem still remaining to be solved, and which makes many ideal geothermal locations loathsome to people, is the stench and foul smell of such gases as sulphur escaping along with the steam. But in many places these very sulphurous spots are gaining undeniable popularity as health spas. Italy was the first to tap the potential of geothermal energy, New Zealand, Philippines, Mexico and California followed, and now this undepletable source of energy is taken for granted. We needn’t fear about this well drying up: the hot molten core of our planet earth won’t cool at least for another one million years.

  4. If production and distribution of power had not established itself as a very great industry, India certainly would have turned to utilizing conventional sources of energy such as wind, geo-thermal, tide and solar. Nuclear reactors are the most convenient source of energy to industrially established energy producers as it has the advantages of supply can be effected when it is needed and more commercial gains and international transactions can be carried on, making good use of the rarity of its raw material. Other energy sources have to be used non-stop. But they are free energy from the earth, and so, cannot be sold at huge profits like nuclear energy. They do not become a burden for future generations by way of generating undisposable waste. When this question is put before the administrative authorities who are only the obeying servants of the energy business, they accuse protestors against nuclear energy to be lunatic. In India, in 2012, the government of India and Tamilnadu state forcefully subjected nuclear protestors of Koodankulam Nuclear Power Plant to psychiatric counseling which attracted explanatory summons from the National Human Rights Commission of India. When energy businessmen start their move, there is now no one in India who does not obey their orders, even if accused of violating National Mental Health Act. They dutifully serve their masters. Protection of civil liberties come next only, second to interests of energy men. Our supply of uranium, coal, oil and gas will one day run out. We are already running low in them. But there is no likeliness of wind, sun, tide and geo hotness stopping, not even after 5 million years. Then why is this adamant insistence on nuclear energy except for pocketing billions by way of construction, operation and maintenance of nuclear power plants, profits from selling unnaturally made industrially produced energy and also by way of keeping nuclear wastes sealed against proliferation for 1000 years? World Bank statistics shows that average present day energy consumption of the world is about 562 Peta Joules which is below 1 Zeta Joule. It has been estimated that Planet Earth produces nearly 4000 Zeta Joules each year which go unused, which vainly vanishes into atmosphere. How ignorant can advocates of nuclear energy in this world can be! One can argue for arguments’ sake that for tapping all this free energy, huge investments would be needed, but which does not need huge investments, nuclear energy? Calculate the sum total of all investments made by all countries in the world so far for constructing nuclear plants which remain functional for three or four decades, and we would get the immensity of the influence of energy business. But the earth’s other energy sources are undepletable and those plants can be used for centuries, if well made, with a quarter of money the world spent on nuclear plants. Who is to be tested for insanity, protestors or promoters of nuclear plants?
