Bajwa Sahib, If you have access to the empty land in Punjab/ Haryana/ Himachal , solar/wind energy power plant can be put free and attached to the grid.

NEW DELHI – Coal India Ltd. is considering acquiring stakes in mines in South Africa in a joint venture with the provincial government of Limpopo, the company's chairman Nirmal Chandra Jha said Thursday.
"The proposal is likely to be considered by our board in a meeting later this month," Mr. Jha said.

Theo_Fidel wrote:Yes, Solar PV is very expensive, need at least 1.5 lakhs for a 2 kva system w/ battery. Though it may have dropped a bit the recent declines. The huge problem is net-metering is not allowed in India, meaning you use the grid to balance your output rather than a battery. GOI is now finally working on this problem. I would not recommend residential PV in India right now unless you have money to burn. The pay-back period is unrealistic, often in the 15-20 year range.
I would strongly recommend solar water heaters. If you have an electric Geyser you would be surprised how much it consumes. An investment of Rs20,000 or less (depending on deals), could potentially eliminate 1/3 of your electric bill. This was my fathers experience.

IMHO the numbers speak for themselves. We have no option but to go Solar, now that PV is $1 per watt and heading lower. I urge you to run the numbers one more time with the new price inputs.

Given that laying cables under the ocean is quite common, one could create a whole damn grid under the ocean.
Even Sharks could have light then. Damn, I wish I could patent this

The four parks – to be set up in Jodhpur (below photo), Jaisalmer, Bikaner and Barmer – will mirror Gujarat’s 500MW Charanka project, which offers developers easy grid connections and other benefits.

Most people don't know this but Gujarat is actually #1 in 'Total' Solar potential. Rajasthan is #2. A few limited areas in Rajasthan however have the most sunny days in a year, 330+ in a few areas. Annual average sun light of 2500 hours. This is what makes those particular areas attractive.

Why China is allowed to dump Cheap and less Quality Solar cells while local and international companies are asked to set up their companies? this is a direct threat to the local companies in India and now someone must have been paid here in their accounts.
A unit of Talma Chemical Industries Pvt., owned by the family of Indian investment banker Vallabh Bhanshali, has completed a 25-megawatt solar power plant.
It was built with photovoltaic panels from Hanwha SolarOne Co. (HSOL) and China Sunergy Co. (CSUND), and funds from State Bank of India, Visual Percept Solar Projects Pvt. said in a statement e-mailed today. The plant, in the Surendranagar district of Gujarat, has signed a 25-year agreement to sell power to the state’s utility.
The project cost, undisclosed by the unit, was expected to be 3.3 billion rupees ($65 million), ICRA Ltd., owned by Moody’s Investors Service, said when it assigned a BB+ rating to 2.31 billion rupees of the solar company’s debt in August.
Germany is installing so many solar panels that profits at coal-fired power stations run by EON AG and RWE AG may slide more than 40 percent by the middle of 2012.
The country, Europe's biggest electricity market, installed a record 3,000 megawatts of new panels in December, the Bonn- based Bundesnetzagentur, the network regulator, said this month. The prospect of a glut of power may drive the margin from burning coal to generate electricity, the so-called clean-dark spread, as low as 5 euros ($6.46) a megawatt hour by July, according to UBS AG. It was at 8.68 euros at 8:49 p.m. in Berlin today, data compiled by Bloomberg show.
"There is not much overcapacity yet, but it will get worse as there is a lot of new supply coming," Patrick Hummel, an analyst at UBS in Zurich who has covered German energy for more than 10 years, said by e-mail on Jan. 16. Germany may be oversupplied for at least five years, according to the bank.

“If we have to meet 5,000 kWh per capita consumption of electricity at an estimated usage of 8 trillion units per year, coal will last only 11 years, where as Uranium and its derivatives will not last beyond 40 years. Sustainability will come with the use of solar energy and Thorium, the latter will last for 170 years. They are the only forms of energy that will meet our needs,” he said.
Commenting on the Solar Mission, he said: “We are now looking at the scale of the mission and also at bringing the costs down. We are looking at capacity-building. Considering the technological content, we have to plan in a manner that is cost-effective,” he said.
He added that the initial challenge for the mission was understanding whether India’s large land surfaces could withstand the weathering. “I am afraid we have not fully understood this factor as yet. Making sure surfaces retain their properties is a challenge,” he said.
