A year ago India announced that solar power would be a major part of its climate action plan but between then and now, other than some project announcements, we haven't heard all that much. But now Worldwatch Institute reports that Indian newspaper The Hindu has seen a draft copy of a national solar power plan which seriously ups the ante:
According to the leaked document, India's "solar mission" will include measures for rapidly expanding the use of small-scale photovoltaic panels, solar lighting systems, and commercial-scale solar plants, in order to drive down costs and encourage domestic solar manufacturing. The efforts would occur in both rural and urban areas and target residential as well as commercial users. The plan also proposes scaling-up centralized solar thermal power generation, with the aim of achieving cost parity with conventional grid power by 2020 and the full necessary energy infrastructure by 2050.
With India's installed solar capacity currently at only 3 megawatts, this would be the most ambitious solar plan that any country has laid out so far. The scope of the initiative would also match and ultimately far exceed India's plans for nuclear power generation.
Specifically the plan aims to have 20,000 MW of solar power by 2020, expanding to 100,000 MW by 2030 and 200,000 by 2050.
Funding This All Might be the Most Ambitious Part
Which not only is "ambitious" but also going to be expensive to implement: Worldwatch cites Greenpeace's Energy [R]evolution report in saying that by 2050 India could generate 69% of its electricity and 70% of its heating and cooling needs from renewable sources, but that will require an investment of $154 billion.
In the leaked draft, government investment would amount to $18-22 million, with presumably the balance to be made up through international financing mechanisms.

GE plans $1.5 billion in cleantech R and D by 2010
GE eyes $1.5 billion in cleantech research by 2010
General Electric Co aims to boost its investment in clean-tech research and development to $1.5 billion a year by 2010, the largest U.S. conglomerate said on Wednesday in its annual “Ecomagination” report.
The maker of products ranging from electricity-producing wind turbines to energy-efficient compact-fluorescent lights, wants to grow green-business revenues to what it called a “stretch” target of $25 billion next year, up from $17 billion in 2008 and $6 billion in 2004….
GE said it expects stimulus spending in the United States, China and elsewhere around the globe to create about $400 billion of new demand for green technologies and clean-energy products, including wind turbines and solar panels.
The company earlier this month said it was building a plant near Albany, New York to build a new generation of high-capacity batteries that would power its upcoming hybrid railroad locomotive. Last month, it said it was working with Florida utility company FPL Group on the roll out of a “smart grid” system intended to encourage homeowners to lower their electricity consumption during peak demand times.
Global CEOs back greenhouse gas cuts, carbon caps
Global business leaders added momentum to prospects for a new U.N. climate treaty by agreeing Tuesday that the world must cut greenhouse gas emissions in half by mid-century by setting specific limits on carbon.
Government officials reported little progress in setting such limits, however, showing how distant a new treaty remains.
Some 500 CEOs and other top business experts said at the conclusion of the three-day World Business Summit on Climate Change in Denmark that “immediate and substantial” emissions cuts were needed by 2020, followed by cuts of at least 50 percent of 1990 levels by 2050. They said governments should use the marketplace to set a global price on carbon instead of taxing it, according to a statement from conference organizers.
Carbon allowances — the glue in House energy package
A massive climate bill has taken its first step forward in the House, its path paved by the giveaway of allowances — free greenhouse gas emission permits designed to mute the economic impact of a carbon cap-and-trade program.
Free allowances — each conveying the right to pump a ton of greenhouse gases into the atmosphere — were the glue that held the sprawling bill together for Reps. Henry Waxman (D-Calif.) and Ed Markey (D-Mass.) and fellow Democrats on the Energy and Commerce Committee last week.
The “cap” of cap and trade would impose steadily tightening limits on greenhouse gas emissions. Companies covered by the bill whose emissions exceeded their caps would have to purchase emission allowances, or buy offsets — for example, by investing in rainforest preservation. Some allowances could be banked or borrowed to ease transitions. But the decisions would affect firms’ choices of fuels, introduction of new technologies, and decisions to hire, fire, expand, shrink or move operations overseas.

Repost ~ 'Distributed power' to save Earth
By Jason Palmer
Science and technology reporter, BBC News, Prague
Economist Jeremy Rifkin galvanised the Research Connections 2009 conference in Prague with a roadmap to simultaneously solve the economic and energy crises.
He proposed a pan-European strategy of small-scale energy generation and smart energy grids that make everyone a partner in energy.
What is more, he said, the plan would create millions of jobs and foster investment that would see the end of the current economic crisis.
Mr Rifkin leads a roundtable of 100 top CEOs and government officials who have subscribed to the plan.
The roundtable is part of the Foundation on Economic Trends, which Mr Rifkin founded.
He said old economic models will not see humanity through, and the combination of the climatic, energy and economic woes of the planet created a "perfect storm" that will see in a new era for its inhabitants.
But such a revolution is not unique to human history, he said.
"The great economic revolutions in history occur when two things happen," he explained.
"First, we humans change the way we organise the energy of the Earth; we've done this frequently over the course of our history.
"Second, and equally important, we change the way we communicate to organise new energy regimes. When energy revolutions converge with communication revolutions, those are the pivotal points in human history."
" Your building becomes your power plant, just like your computer becomes your information vehicle to the world "
Jeremy Rifkin
The current renewable energy push, in common with the information and communication technology revolution that characterised the 1990s, is just such a pairing of regime changes.
But in Mr Rifkin's grand plan, every citizen of the EU would participate in order to revolutionise the way energy is generated, used, and monetised.
Four pillars
Although the sheer scope of the idea raised eyebrows throughout the room, Mr Rifkin laid out a cogent, four-part plan that he said could in one stroke dispel the perfect storm he described.
The first two pillars of the plan were a call to technological arms: further develop renewable energy technologies' efficiencies, amplify production to access "economies of scale", and develop means to store the intermittent energy they harvest.
The third pillar is a common idea writ very large indeed. He called for a pan-European commitment to microgeneration - small installations of renewable energy technology work in place of, for example, vast wind farms - but on every single building already up or yet to be built.
"We cannot build enough centralised wind and solar parks to run Europe," he said.
"If this energy is distributed over every square foot all over the world, why would we collect it only at a few points? The problem is we're using 20th century, centralised, top-down business models."
Instead, Mr Rifkin suggested overhauling the technology of infrastructure and architecture such that buildings have integral power generation: solar panels and small vertical wind turbines on roofs, heat pumps harvesting geothermal energy in basements.
In rural settings, agricultural waste could be used to generate methane and in coastal regions, tidal power could be harvested.
"Your building becomes your power plant, just like your computer becomes your information vehicle to the world. Every home, factory, industrial park, every building is converted," he explained.
While existing buildings could generate a sizeable fraction of their energy demands, new buildings would be "positive power" - generating more than they need through grand changes in building materials and architecture.
Jump-start
Such an idea is not new; in fact, installations are already underway. Mr Rifkin cited car maker GM's Opel factory in Zaragoza, Spain, which sports a $78m (£52m) solar panel array.
It produces some 10 Megawatts of power, which means the energy savings could pay for the installation in just nine years.
Elsewhere in Spain, Navarra and Aragon have, in the past 10 years, moved to generating 70% of their energy with renewables.
Using wind turbines in the Pyrenees, hydroelectric generation from snowmelt, and sun-tracking solar arrays, Aragon will be 100% self-sufficient in six months and be in energy surplus in six more.
"Everyone can do that tomorrow," Mr Rifkin emphasised. Moreover, it is a handy way out of an economic abyss.
"If you want to jump-start an economy it's always about construction. You jump-start not hundreds of thousands of jobs building solar collectors, but millions of jobs reconverting the entire infrastructure."
The scale of the proposed changeover is unconvincing for Paul Ekins, professor of energy and environment policy at King's College London.
"People tend to want power when they demand it and they tend to want it to be there all the time," he told BBC News.
"It's certainly possible that microgeneration has a role to play in the future energy system, but my view is that central generation is likely to be a very important part of satisfying that demand."
'Distributed capitalism'
The fourth pillar of the plan would make everyone a stakeholder in the scheme by overhauling the outdated power grid system.
"We're going to use the same tecnology that created the internet; we take the power grid of the EU and turn it into an 'intergrid' that works just like the internet.
"Say you're producing 30% of your energy need, it's peak period in the middle of the day and you don't need the electricity. If millions of people send just a little bit back to the grid, peer-to-peer just like we send information on the internet, that's distributed power."
But the distributed computing allowed by the revamped power grid could introduce a new economic paradigm - what Mr Rifkin calls "distributed capitalism".
"The main grid [will be] completely distributed, software connected to sensors connected to every appliance in your home: thermostat, washing machine, toaster, everything.
"At any one time the system will know what every washing machine is doing in Europe. If you have peak demand, not enough supply, software can say to two million washing machines 'forget the extra rinse'.
"If you bought the program - it's all voluntary - you get a cheque at the end of the month or a credit from the electricity company."
Like microgeneration, the idea of such "smart grids" has been circulating in the energy community for some time. But it is the sheer scope of all facets of Mr Rifkin's plan that makes it unique.
He has formed the "Third Industrial Revolution Roundtable" with 100 leaders from industry - big names such as IBM and BASF are on the list - as well as governments to further promote the idea.
And he is sure that the EU will continue to lead the way, citing the "golden goose" of the union: it is the largest internal market economy in the world, making it particularly poised to undertake such an ambitious plan.
Professor Ekins wonders about the likelihood that all the facets such a long-term, high-investment initiative is what the future holds.
"The world has room for visionaries," he said, "and one of the characteristics of visionaries is that their total vision very rarely comes true.
"Normally the future ends up having some aspect of different competing visions."

GreenSmith launches backup battery for grid
Washington D.C.-based GreenSmith Energy Management Systems unveiled technology it says can solve the peak demand problems of U.S. utilities.
CEO Rodney Smith said the company has designed a battery control and management system that, when paired with lithium ion battery GreenSmith acquired from a manufacturer overseas, can store 20 kilowatt-hours at a time and provide between 3,000 and 4,000 full-discharge cycles.
The idea is that utilities could charge the battery when it's cheaper to produce energy, such as in the middle of the night, and could discharge that energy onto the grid when it's most expensive to produce power.
Smith said ideal circumstances would be to use the battery during peak demand instead of firing up a peak power plant, which is more expensive to run. The unit could help reduce the need for additional power plants and prevent utilities from losing excess power generated.
"Utilities are far more receptive to distributed storage technologies than they are to smart grid, and for a reason," Smith told the Cleantech Group. "Grid replacement is like trying to replace the air traffic control system. You have to put a lot of money into it before you see any rewards from it. With our technology, you get the benefit right away."
The technology can be paired with intermittent renewable energy sources, such as wind and solar, to better align power supply with power demand, Smith said.
That field is also being targeted by companies such as ZBB Energy, which has contracted with the Australian government to accelerate development of the company's zinc-bromine storage systems for renewable energy projects (see ZBB gets Australian contract for renewable energy storage and ZBB, Zest in energy storage deal).
Tyngsboro, Mass.-based Beacon Power (Nasdaq: BCON) is promoting its multiple-flywheel systems to supply or absorb electricity, giving extra stability to a grid that's experiencing demand or supply peaks (see Beacon slows flywheel storage plans).
According to the Carnegie Mellon Electricity Industry Center, there is a strong economic case for flywheel installations to improve grid stability, as evidenced by the New York Independent System Operator and the PJM Interconnection.
Last year, Windsor, Colo.-based Ice Energy revealed a device to shift up to 95 percent of air-conditioning load to off-peak hours while providing full cooling performance (see Ice Energy cools down power demand).
Other technology is attempting to use molten salt for energy storage (see Concentrated solar gets salty and Cleantech Group picks winners and losers in concentrated solar thermal).
GreenSmith's systems are designed to be managed from a central location, either programmed to optimize cheap energy price or manually controlled. Utilities, regional transmission agencies and co-ops in the U.S. are the current market, but GreenSmith eventually plans to target global markets, especially those with intermittent access to the electric grid.
Consumers aren't the target for GreenSmith, although Smith said the devices could be modified for home use.
GreenSmith is in talks with several utilities and expects a pilot project with a utility to begin operating in about two months. The company plans to produce commercially by mid-2009, with tens of thousands of units sold that year.
After that, GreenSmith expects to sell hundreds of thousands of units to utilities a year. A large utility would probably use about 3,000 units in a pilot test and as many as a million units in full deployment, whereas a small utility might seek between 100 and 1,000 for a pilot, Smith said.
Each unit would cost about $10,000, minus volume discounts, which Smith said produces an energy cost of less than 10 cents per kilowatt hour.
GreenSmith has raised an undisclosed amount in angel funding from private investors. The company is currently raising a Series A round led by Blue Lagoon Capital, but Smith declined to reveal the size of the round, saying that reports of a $20 million round were incorrect.
The company, which Smith said has a "handful" of employees, originally pursued smart grid technology when it was founded in 2007 as an offshoot of think-tank Intelligent Power Unit. Smith decided energy storage presented a more lucrative business model because it was faster to market.
"We thought, what if instead of trying to fight peak you could shift peak?" Smith said. "So we decided to focus on storage."
