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.

Net Metering is a very important Electricity Policy for the promotion of Distributed Electricity Production from Renewable Energy Sources especially Solar Energy.All consumer establishments connected to the power grid have an electricity meter installed which measure the amount of power consumed during a month in Kilowatt Hours (KwH) which is known as one unit.The power utility compiles the data for power consumption during 1 month and sends a bill which is usually the number of KwH multiplied by the retail electricity rate which can vary widely from 10c/KwH to around 35c/KwH depending on the geography.

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.

China which has the most ambitious growth planned for nuclear energy is already rethinking its target 3 weeks after the Fukushima plant in Japan started spewing out radioactivity.Note there has been a strong global backlash against nuclear energy around the world and 7 nuclear plants in Germany have been closed all but in name.Other countries like South Korea,Italy,Switzerland are rethinking of what do about their nulcear reactors giving the massive tail risks with nuclear generation.Already 2 earlier nuclear disasters in Chernobyl and Three Mile Island had massively damaged the surrounding ecosystem poisoning humans and animals alike with radiation.Japan too may see its land areas near the reactors be quarantined for many years as TEPCO has failed to control the nuclear plant and government will probably pour concrete.

Obama’s outlined a New Energy Policy as he periodically does without any far reaching national goals on to reduce America’s dependence on billions of barrels of imported oil which cause global warming,finance terrorist and prop up brutal regimes in the Middle East.However his periodic bursts of rhetoric on the US Energy Policy is nothing but a lot of empty gas without any specifics.Earlier he used to stress on nuclear energy which has been thrown out of the window with the Fukushima nuclear disaster.His plans of supporting the nuclear energy industry with $36 billion in DOE loans seems a bad if not a gruesome joke.Similarly last year his plans of allowing offshore drilling for Oil also fell flat after the massive BP Oil Spill ecological disaster.

The Reactor 1 of the failed Fukushima Daichi plant might be recritical as Radioactive Chlorine has been detected suggesting chain reactions continued after the reactor shut down.This is quite alarming and has made Japan thing about pouring concrete into its crippled Fukushima atomic plant IEAE warned that a potential uncontrolled chain reaction could cause further radiation leaks.The risk to workers might be greater than previously thought because melted fuel in the No. 1 reactor building may be causing isolated, uncontrolled nuclear chain reactions.Dumping concrete on the plant would serve a second purpose: it would trap contaminated water, said Tony Roulstone, an atomic engineer who directs the University of Cambridge’s masters program in nuclear energy.
