Cost of Renewable Energy Projects
| The cost of renewable energy power generation in India is competitive
compared to the cost in other countries. In India, the solar power
installation cost has reduced significantly over last three years. The
installation cost of wind power projects in India is also competitive in
comparison of other countries. This was stated by Sh. Piyush Goyal,
Minister of state for Power, Coal & New and Renewable Energy
(Independent Charge) in a written reply to a question in the Lok Sabha. The Minister further stated that the India has signed 39 Memorandum of Understanding (MoU) / Agreements in the field of Renewable Energy, under which there are a number of Joint Working Groups (JWG). The cooperation also includes issues of developing renewable energy sources in the country. The 12th Five Year Plan targets a cumulative renewable power installed capacity of 55 GW by end of March 2017. Rs.19,113/- Crore has been allocated in the Five Year Plan for the purpose, the Minister added. |

Power Generation at Reduced Cost in Coming Years
The cost of power generation from new and renewable
energy sources is expected to further reduce in the coming years. The cost of
generation of solar power has already come down to Rs. 8 per unit from Rs.18
per unit few years back. This was stated by Dr. Farooq Abdullah, Minister for
New and Renewable Energy while delivering his inaugural address on the
Stakeholders Workshop on New and Renewable Energy in the Capital today. Dr.
Abdullah stressed on the importance of the new and renewable energy sources in
providing energy access to almost 40 per cent of the country’s population which
lacks energy access at present. The Minister hoped that renewable energy could
become the biggest driver of inclusive growth in rural and remote areas. Highlighting the progress made by India in the field of new and renewableenergy, Dr. Abdullah stated that UPA has given a big thrust to this area and the Jawaharlal Nehru Solar Mission launched in January, 2010 has led to great success in the area of Solar power. India today has become no. 5 in wind power generation and has developed wind turbines capable of generating 8 Megawatt of power.
Apart from senior officials of MNRE and CAG, a range of stakeholders, including regulatory agencies, 11 State nodal agencies, PSUs like NTPC, NVVN, NABARD, Associations in Solar and Wind Energy, NGOs, IIT Roorkee and subject matter experts from the sector are participating in the one day workshop organized by the office of C & AG of India.
Dr Farooq Abdullah highlighted the importance of promoting the Green Buildings concept of saving the energy consumption since almost 40 per cent of the total energy is utilized in the building sector. The Ministry is pursuing promotion of green buildings in a major way and every new Government building to come up shall have a GRIHA rating of 3 and above.
Delivering the welcome address, the Comptroller and Auditor General of India Shri Shashi Kant Sharma said that CAG has planned to undertake an All India Performance Audit of the New and Renewable Energy sector in the near future. Shri Sharma said that this subject has been chosen keeping in view the tremendous growth potential of renewable energy and its growing importance for the economy and well being of the population at large.
Shri Sharma said that the CAG organization possesses a good experience of undertaking Performance Audit, which provides an independent assessment of the extent to which the audited entity, programme or organization operates efficiently and effectively, with due regard to economy.

Cabinet's approval for setting up of institute for solar research
The Union Cabinet has approved the proposal for
setting up of an autonomous "National Institute of Solar Energy" (NISE)
to assist the Ministry and function as the apex national centre for
research and technology development and related activities in the area
of solar energy technologies in the country. The National Institute of Solar Energy (NISE) is to be set up immediately by converting the Solar Energy Centre (SEC),Gurgaon with a long term vision to develop it as a world class institute.
Solar energy technologies are evolving continuously and the proposal to set up the National Institute of Solar Energy is an innovative idea which will accelerate the process to support induction of the latest technologies to ensure maximum cost benefit and lead to early commercialization. Solar power project developers will be motivated to use more efficient and optimized solar components.
A broad based national team in the form of a Review-cum-Strategy Formulation Committee would be set up with representation from industry, the scientific community, financial institutions etc. to prepare a blue print. This committee would look at various models available in the country and outside and prepare a roadmap for the Institute.
In order to enable this Institute to acquire the envisaged stature, reorientation of the present management system, better infrastructure and highly skilled manpower would be required. Public private partnership with future investment coming from both Government and private sector would be important so that the activities can be expanded.
Background:
Setting up of an apex national centre for Solar Energy is a part of the JNNSM, which was considered by the Prime Minister's Council on Climate Change in August, 2009. The Jawaharlal Nehru National Solar Mission (JNNSM) and other related proposals were approved by the Govt. in November, 2009. While approving the JNNSM, the Govt. also approved specific targets and budget for the first phase of the Mission till March, 2013. This includes R&D in solar energy, including setting up of a Centre of Excellence as an apex centre on different aspects of solar energy technologies.

Solar Water Heating Systems
Power cut is a consistent problem at the peak hours in
summers as well as winters in most of the North Indian cities. In such cases,
switching the heating load over to non-conventional sources of energy from the
conventional type of resources can eradicate this problem and inconvenience
that arise especially during early hours of peak winter season when the hot
water is needed the most. The gap between the demand and supply of electricity
can be bridged to a great extent by using solar energy based appliances such as
Solar Water Heater.
China stands at the top position in the world in the Installations of Solar Water Heating Systems with approx. 80.3% of total installations in the world.
Solar Energy Appliances not only bridge the gap between
demand and supply of the electricity but also save a lot of money due to their
negligible running cost and also they help in maintaining the ecological
balance by reducing pollution.
Solar Water Heaters are designed to heat water by using
the solar energy which is available on earth free of cost. Water can be easily
heated to a temp. of 60-70˚C.

| A typical solar water heater |
Main components of solar water heater system are:
A) Solar Collector (to collect solar energy)
B) Insulated tank (to store hot water)
C) Supporting stand
D) Connecting pipes and instrumentation etc.
Solar Water Heaters can be of following two types:
1- FPC :Flat Plate Collector based
2- ETC :Evacuated Tube Collector based
In FPC based Solar Water Heaters the solar radiation is
absorbed by Flat Plate Collectors which consist of an insulated outer metallic
box covered on the top with tempered glass sheet. Inside there are
blackened metallic absorber sheets with built in channels or riser tubes to
carry water. The absorber absorbs the solar radiation and transfers the heat to
the flowing water. Most flat plate collectors have two horizontal pipes at the
top and bottom, called headers, and many smaller vertical pipes connecting
them, called risers. The risers are welded to thin absorber fins. Heat-transfer
fluid (either water or water-antifreeze mixture) is pumped from the hot water
storage tank (direct system) or heat exchanger (indirect system) into the
collectors' bottom header, and it travels up the risers, collects heat from the
absorber fins, and then exits the collector out of the top header.
In ETC based Solar Water Heaters Evacuated Tube Collector is made of double
layer concentric borosilicate glass tubes evacuated for providing insulation.
Since heat loss due to convection cannot cross a vacuum, it forms an
efficient isolation to keep heat inside the collector pipes.The outer wall of
the inner tube is coated with selective absorbing material. This helps
absorption of solar radiation and transfers the heat to the water which flows
through the inner tube.
Flat plate collectors are generally more efficient than ETC in full
sunshine conditions. However, the energy output of flat plate collectors is
reduced slightly more than evacuated tube collectors in cloudy or extremely
cold conditions.
FPC based systems with metallic collectors are costlier than the ETC based
systems with glass tubes for the same system capacity (Ltr/Day).
