Hydroelectricity is one of the largest sources of energy accounting for roughly 20% of the worldwide demand of electricity with around 800 GW of capacity installed.There is considerable potential still left and developing countries like India and China can be expected to install another 500 GW over the coming years.Hydroelectricity is very important as it does not lead to GHG emissions and contribute to global warming.It also does not have the drawbacks like other renewable energy forms of high costs and intermittency.The advantages of hydroelectricity are substantial enough to far outweigh any disadvantages.But like nuclear energy,hydro power has some tail risks which can lead to catastrophic damage.The costs of hydroelectricity are not a simple function of dollar costs.It should also take into account the massive displacement costs in case of massive hydro dams,the loss of ecology and potential tails risks which can lead to massive payments.

India's Green Companies are seeing tremendous growth backed by the nation's massive energy demand increase.The 8% Plus Economic Growth coupled with the already massive electricity deficit which makes brownouts of 8 hours a day normal in many places in the country provides the macro background underpinning the growth.India's Green Industry is still in a nascent state compared to the massive solar and wind industries in countries like China and Germany.However attracted by the massive potential a number of companies small and large have entered the fray.Most of India's large energy groups,utilities have already established a small presence or are in process of doing so.While Wind Energy is the largest Renewable Energy Industry in India after HydroElectricity,Geothermal Energy is non-existent without a single large commercial plant.Biomass Energy is quite well developed and Solar Energy is the fastest growing Green Industry.Here is a comprehensive list of the Green Companies in India operating in the different Alternative Energy Sectors.

Hydroelectricity is the production of electrical power through the use of the gravitational force of falling or flowing water.Hydroelectricity capacity is around 800 GW accounting for almost 20% of the global electricity capcity.China and Canada have the largest hydro capacities in the world.If you consider Hydropower as renewable energy,then Hydro is the most widely used renewable energy in the world.In fact Hydroelectricity is the 3rd biggest source of electricity in the world after coal and oil/gas.Hydroelectricity power plants can have massive capacities with the Three Gorges Dam in China being the world's largest at 22.5 GW.The Itiapu and Guri Dams in South America are the 2nd and 3rd largest with 14 GW and 10 GW capacities.China is set to double its massive hydroelectric capacity to almost 400 GW by 2020 from 20 GW currently.The advantages of Hydroelectricity are many

Alternative Energy in India saw significant growth in 2010 with the last 9 months of the year seeing capacity additions of 1800 MW which is almost 10% of the total installed capacity of 18500 MW.The growth in renewable energy was led by Wind Energy which forms almost 70% of the total renewable energy capacity in the country at around 13500 MW.The strong incentives given by both state and central government has led to the sharp growth of wind energy.Note Wind Energy is quite close to Gas based electricity price.India Needs at least 68 GW of Renewable Energy Capacity by 2020 to meet its RPS target of 15% set by CERC (note this is capacity only not hours of electricity).

China has the world's largest hydro power capacity at 200 GW and it plans to double the capacity by 2020.China is mostly dependent on Coal Power and Hydro Power to meet the electricity demand from its fast growing economy.China has the world's second largest electricity capacity at 850-900 GW second only to USA at ~1000 GW.This will be soon be overtaken as China continues to grow at 8-10% and its electricity per capita is still much below developed world standards.China is already the world's biggest consumer of Energy and emitter of Greenhouse Gases.Despite rapidly investing in Nuclear and Renewable Energy,China's voracious demand has made the growth of Fossil Fuel Energy unsustainable.It already consumes 3 Billion Tons of Coal per year and is already importing around 180 million tons per year.

India has set up ambitious targets of meeting 15% of its Energy Needs from Renewable Sources up from around 5.5-6% in 2010.WIth India's Electricity Capacity expected to rise to 450 GW from around 165 GW,this would imply that around 67.5 GW of Electricity Capacity would be needed up from around 16 GW.This would mean around 5 GW of Capacity addition every year in the next decade which is a very tall order.20 GW could be met by Solar Energy according to the Jawaharlal Nehru Solar Mission (JNNSM).Most of the rest would have to met by Wind Energy.Biomass Energy has high costs and reliability problems which mini hydro potential is only 1 GW.Note this is just the capacity I am talking about,for meeting the electricity generation,capacity additions would have to be greater as Solar Energy and Wind Energy have only 20-30% Load Factor compared to 60-80% for Fossil Fuel Energy Sources.Nuclear Energy can contribute another 20 GW.
Renewable Energy in India is growing at a rapid pace increasing its share of the total capacity from 2% in 2003 to around 10% in 2010.However the share of electricity generation is still quite low at 3% due to the lower capacity load factors of Green Energy Sources compared to Fossil Fuel Sources.The Total Installed Capacity of Renewable Energy in India is around 16 GW with Wind Energy taking the Lion's share at almost 70% followed by Small Hydro at 15% and Biomass Energy at 12%.Solar Energy in India till now has a capacity of just 6 MW which is estimated to grow to 22 GW by 2022 making Solar Energy one of the Biggest Growth Opportunities in the Field of Indian Energy.

Earthquake Vulnerability - Large Dam Construction has been linked to increased propensity of Earthquakes.Massive Earthquakes in China and Uttarakhand in India were linked to the building of Massive Dams in these countries.Building of Massive Man Made Structures along geologically sensitive areas has not been properly studied and understood till now
Summary
While Hydro Power is a necessity for an energy starved and growing economy like India,its effect have to be properly assessed and understood before going on a hydro binge.NTPC lost almost $300 million after its 600 MW project was canceled 5 years after getting permission.This was done in the face of large scale protest by local groups and NGOs.2 other projects in Uttarkhand have also been rejected leading to more losses.

Note this Hydro Plant will cost around $31 Billion which is quite costly at $15/watt if the the $31 Billion is used for the 1800 MW capacity.This is is almost 15x the cost of a typical Hydro Capacity and would need massive subsidies.Papua New Guinea is a poor country and might receive aid from Australia but the $31 Billion would make even the richest country balk at this price.Australia is not exactly energy deficient with massive resources of coal,wind and solar energy.In Renewable Energy the country has been quite slow with provinces like NSW and South Australia promoting renewable energy through regional subsidies.Hydro Power is the main source of Clean Power accounting for 90% of the Clean Energy Mix.The Project will take 10 years to build and their remains an outside chance that Oil Prices become so high that 24 hr Hydro Power at that time might make sense at $15/watt.

Now Blackstone has decided to gamble on India's Power Deficit Story by investing $300 million for an undisclosed stake in the company.With investment plans of $6.5 billion and parent company sinking under loads of debt,Moser Baer Projects desperately needed equity which has been provided by Blackstone.Its previous track record in Solar and Optical Media does not inspire a lot of confidence.But India's 8-9% Growth Rate is like a Rising Tide which will lift all sorts of Boats.Blackstone is perhaps gambling more on that rather than on Moser Baer.
