The ongoing problems at the stricken Japanese Nuclear Plant at Fukushima may see new problems given the prolonged cooling by water.Note it has already manifested itself as 11,500 tons of radiated water was dumped into the Pacific leading to protests from South Korea and dangerously contaminated fish.Further problems may arise as NY Times reports from a nuclear assessment report on each of the 6 reactors at the Dai-ichi plant.The tons of seawater being used to cool the temperature could result in a dangerous structural damage to the containment vessels of the reactors.Note this unconventional cooling of the Nuclear Plant may give rise to unthought of problems and complications.The spent fuel rods where hydrogen is being generated may react violently with oxygen in the air leading to violent explosion as was seen in Reactor 2 in the early part of the crisis.Salt has also been accumulating in the reactor from the seawater which may prevent circulation of newly added water.

The total installed nuclear generating capacity in the world is around 375 GW (WNA) with another 170 GW in planning g state and another 170 GW being proposed. The largest nuclear power is Europe with an installed capacity of 131 GW, ie. 34% of the total world capacity. The second largest country is the USA with around 27% of the world nuclear capacity. The installed capacity of USA is 101 GW. These figures are projected to accumulate to 144 GW & 136 GW respectively by the end of year 2035, according to the EIA. Japan & Russia are the 3rd & 4th in the list with an installed capacity of 49 GW & 23GW respectively.

Nuclear Power has come under assualt in the aftermath of the Fukushima Nuclear Accident with Nuclear becoming a four letter word.However Nuclear Energy cannot be ignored becauses its benefits are unique in some applications and cannot be substituted by any other means.Nuclear Power also cannot be replaced in the short term from its most widely used application of generating Electricity.Note Nuclear Power accounts for almost 15% of the Global Electricity and in some countries is the major source of energy.For example France which has 80% of its power coming from Nuclear Fission,its impossible to think of shutting down nuclear plants like Germany which gets around 20%.Note even for USA which has the largest installed base of nuclear reactors shutting down almost 200 GW of Nuclear Capacity is quite unthinkable.Besides Nuclear Energy has massive uses in medical and other applications.This cannot be substituted by other means at all.For example its possible to replace Nuclear Electricity by other means like Solar,Wind even Coal and Gas though its costs will be astounding.But you can't replace Nuclear Energy in Medical Applications like Scanning and X-Rays.Here is a list of the main uses of Nuclear Energy.

The massive dumping of radiation seawater by TEPCO into the Pacific Ocean has triggered outrage amongst various stakeholder groups.Fishermen are angry at is will massively affect the marine life who are bound to get poisoned by the 11,500 tons of radioactive water which is 100 times over the legal limit.A fishing industry group in Fukushima prefecture has asked Tepco to stop releasing toxic water into the sea near the power plant as Radioactive iodine and cesium were found in fish caught off the coast of Ibaraki, north of Tokyo.The Fishermen are already facing a bad time are bound to get hit even worse from this.Green Groups are protesting this deliberate ejection and say that it might be unethical to dump the water if not illegal under international laws.Green Groups are protesting the fact that more efforts could not have been made to store the water in ship tankers or overland facilities instead of taking the easy way out and dumping it in the Pacific.Note the radioactivity spewed from the Japanese Nuclear Plants is affecting nations globally.South Korea which lies very close to Japan has expressed concerns over the toxic water being dumped into the ocean.

Note none of the Indian automakers has a decent EV or a Hybrid selling in the Indian market.Foreign markets on the other had are seeing fierce competition amongst major auto makers to gain a first mover advantage.GM,Nissan,Toyota are the leader in this market with other car makers also in the process of getting in.Hectic alliances and JVs are being forged as this market segment promises to be the fastest growing as the governments give massive subsidies and push.It remains to be seen whether the government in India can push given its record.

Marine Life is expected to be badly affected from the radioactive water.Note IAEA has already found high levels of radiation well beyond the evacuation zone and Greenpeace too has warned about high levels of radioactivtiy.TEPCO has its reputation badly tarnished as it has failed to disclose the levels of radiation and different radioactive elements like Cesium.Note the Japanese Farmers are already facing years of losses and the Fishermen too seems destined to join them as the thousands of tons of water will probably lead to Fishes becoming toxic in that region.

Biomass Energy is highly under-appreciated as a renewable source of energy despite being the most important source of energy during most of human history..Biomass Energy still accounts for 1/3rd of Energy requirements in a lot of countries and is the primary energy source for heating and cooking in rural communities.Biomass Electricity accounts for around 1% of the world’s electricity capacity of around 5000 GW.With advancements in gasifier technology and energy conversion,biomass power plants have become quite popular.Biomass Power Plants are increasing in scale from around 20-50 MW to more than 100 MW as the technology has advanced quite a bit.The only problem for these large plants is securing feedstock for these power plants and storing them.Biomass energy is used mainly for cooking and heating in rural areas.Now it is increasingly being used to generate power as the technology for biomass energy has advanced.Biomass Energy like other Forms of Energy has got its unique Benefits and Drawbacks which are listed below

Hydro Power is one of the largest sources of energy accounting for roughly 20% of the worldwide demand of electricity and for well resourced countries it accounts for majority of the energy.For Paraguay 100% of the electricity comes from hydro power and lot of it is exported as well.Compared to other sources of Energy, Hydroelectric Power is one of the cheapest,non Carbon Emitting,non Polluting,Mature Energy Source.Hydro Power plants have been developed to almost full potential in developed countries because of their superior characteristics and many more are being constructed by developing countries like China and India.However Hydro Power like all other thins in life suffers from disadvantages as well.The failure of a Hydro Dam can result in massive losses of human life and cause widespread devastation.Large Dams have always been controversial leading to displacement of people and ecology.They have also been cited as the reason for earthquakes due to large land changes.Here is a list of the advantages and disadvantages of Hydro Power

Climate Change and Global Warming have been put in the Cold Storage by most world governments as there is little will to fight one of the most pressing challenges facing mankind.With the successive Copenhagen and Cancun Climate Change Meets coming up as croppers,the Poor are left to fight the drastic affects of Climate Change in the face of Severe Weather like Droughts,Floods,Increase Sea Levels.Australia stupidly cut the funding for various Green Programs after facing one of the worst floods in the last century.It did not occur to the short term focused politicians that the Floods may have their root cause in Global Warming.Instead of increasing resources to fight Climate Change,they cut the Funding to help in the Flood Rehabilitation Programs

Economically also Solar Panels are starting to approach retail electricity prices in number of places in the world.Large scale solar power plants are already selling power at 10-15c/KwH which is lower than the retail electricity prices in most places.Still competition between solar panel manufacturers,improving technology and scale are making solar panel costs come down at a rapid pace.In fact Solar Panel prices have declined by more than 50% from 2008 end to 2010 and are expected to fall by an average rate of 10% in the coming years as well.However Solar Panels are seldom bought by the customers directly but are rather bought by the solar system installers/contractors.However its a good idea to know about the costs of solar panels and systems that you are paying for and not get fleeced by unscrupulous solar installers.

A crack in a concrete pit near the Reactor 2 of the Fukushima Plant has been found to be the source of leakage of highly radioactive seawater which was said to reach around 4585 times the legal limit.TEPCO had found the crack in a pit near the Reactor 2 which was leaking this dangerous seawater which was being used to cool the damaged nuclear reactors.An attempt to fill the crack in the pit by pouring concrete failed as the water made the sealing process through concrete impossible.Now a new polymer will be tried to seal the crack though it beats me why it did not occur to the engineers there that the water will make the process of pouring concrete fail.After almost 4 weeks since the nuclear crisis began in Japan operators of the plant are no closer to regaining control of damaged reactors, as fuel rods remain overheated and high levels of radiation are flowing into the sea.

Nuclear Energy is currently forcing a major rethink amongst the world governments as the Japanese Nuclear Accident sharply brings into focus the massive radioactive and poisoning risks from accidental damage to a nuclear reactors.Note this is not the first such incident nor is it going to be the last.The advantages of Nuclear Energy is being sharply reexamined by the policymakers vs the huge risks of a nuclear plant meltdown.Most countries have started reviewing their nuclear plants for safety with a number shutting down old nuclear reactors.The drawing plans of new nuclear plants is also on hold as safety regulations are strengthened.Nuclear Energy accounts for around 15% of the world's production of electricity and for some countries like France there is no alternative in the short term with 80% of the electricity coming from nuclear reactors.China has a huge target for nuclear energy of 80 GW by 2020 but that too is coming under attack with a NDRC official talking about lowering it by substituting it with other renewable energy sources like solar energy.Here are the Nuclear Energy Advantages vs Disadvantages.

Solar Industry is one of the fastest growing industries on the planet and the number of companies in the industry have increased dramatically attracted by the strong growth prospects and low entry barriers.The easy availability of solar producing equipment and low capital requirements for small companies have led to a mushrooming of the number of players in the industry.Its possible to set up a small 30 MW module production factory for as low an investment as $10 million or lower.Though the value add of a pure play solar panel production factory is low and the competetive position quite questionable nonetheless there are hundreds if not thousands of such small module producers in the world right now.Other parts of the crystalline silicon supply chain have also got a number of players though the technology and captial requirements are much higher.Listing out all the solar companies in the world is a difficult task and somewhat useless as well as many of these small scale solar companies will not exist in a few years as competition keeps intensifying.Consolidation in the solar industry will ensue sometime or the other and lead to a much smaller and sustainable industry.

Vestas the No.1 Wind Turbine Manufacturer in the world has been hurt drastically from low cost competition from Asian companies particularly the Chinese Sinovel and Goldwind which have won massive chunks of marketshare.Vestas has seen a slowdown in demand for its Turbines as Western Markets have cooled off.Vestas was forced to dramatically restructure its operations laying off thousands of workers mainly from its domestic Denmark base.The company is now targeting the fastest growing segment of the Wind Power Market- Offshore Wind Energy.Note a number of companies in the Wind Turbine Industry are testing or introducing Offshore Wind Turbines.Siemens,Gamesa,GE are all looking to steal a first mover advantage in this segment.Even shipbuilders like Daewoo,Hyundai,Northrop Gruman are making aggressive moves in the offshore wind market.

The strict environmental regulations of EPA is leading to converion of a Virgina Coal Plant to a Biomass Fired one.Note the US Congress and Senate have failed to move ahead on climate legislation remaining hopelessly deadlocked on any climate deal.Despite numerous draft laws,no common law has been passed as Republicans fail completely in understanding global warming remaining in the pockets of the powerful oil and gas lobby.EPA remains the only government body which is doing something to reduce pollution and at the same time fight for climate change.The strict new rules against emission of harmful gases like sulfur dioxide,nitrous oxide,mercury has forced a Virginia Coal Plant to convert from thermal to biomass.

Solar Panels Efficiency – Range,Technology Dependence,Companies with Highest Efficient Solar Modules
The Companies that make the Solar Panels with the highest efficiences are Sunpower and Panasonic/Sanyo.Sunpower has the highest efficient solar modules in the market using a properietary process and has solar cells with efficiency reaching a top limit of 24%.Sanyo also has very efficient solar panels under the HIT brand name.These solar panels also approach the 18% range (solar modules not cells).Normal crystalline plain vanilla solar panels come in the range of 13-14%.Note solar modules have lower efficiency than solar cells as some area is left for the frame etc.There are other companies that are fast catching up to Sunpower and Sanyo in the high efficiency solar panels as well.Note higher efficiency solar panels sell at higher prices per watt as the require lesser area.AUO which has a JV with Sunpower has recently claimed to have produced the higher efficiency solar panel .

Nuclear Energy is facing a global backlash after the Fukushima incident in Japan as countries race to review their existing nuclear reactors.Nuclear Power had been enjoying a Renaissance in the 21st century as the Chernobyl and Three Mile Radioactive incidents faded from public memory.China is the principal driver of growth constructing reactors at a rapid clip to meet its growing needs with thermal power fast reaching a saturation point.Other growing developing countries like India,Vietnam are also planning to heavily invest in nuclear plants.However all those plans may change as the Japanese earthquake shakes up the nuclear energy industry more than the landmass in Japan itself.Note despite the catastrophic tails risks of nuclear power,it is not going to go away soon due to the large installed base and no fast substitutes available.Note more than 430 nuclear reactors are currently operational globally today and lots more on the drawing board.Note Nuclear Power accounts for around 18% of US electricity capacity and 30% plus for Europe,Japan and Korea.France is the leader with 80% of the electricity generated coming from nuclear fission.Here is a list of the Pros of Nuclear Energy.
March 31, 2011
Nuclear Energy is one of the most important sources of Energy for Humans accounting for almost 15% of the world's electricity capacity.Most of the Developed Countries have installed gigawatts of nuclear power during the heydays of 1960-1980s before the Chernobyl and Three Mile Nuclear Reactor Failures.Nuclear Energy has come into renewed focus after the drastic nuclear accident at the Fukushima Dai-ichi Plant of TEPCO in north Japan.The 6 nuclear reactors have to be decommissioned after most of the safety processes failed at the plant following a massive earthquake.However Nuclear Energy will continue to play a big role as the installed base of nuclear power is too huge and the growing demands of developing countries too large.China and India have massive growth targets for Nuclear Power given its low costs and non-GHG emitting properties.Like Hydroelectricity,Nuclear Electricity is the only large scale baseload source of energy which does not contribute to Global Warming.There are many advantages to nuclear power but the massive tail risks of catastrophic radioactive poisoning is too enormous.This has resulted in a global backlash as people across the world (Germany,India) are protesting to stop Nuclear Power.NIMBY concerns are growing by the day as the fallout from radiation can permanently make a large area inhospitable to human/animal life for many years.Here are the detailed list of the Cons of Nuclear Energy.
March 31, 2011
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.

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.
March 31, 2011
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.

Solar and Wind Energy are the two most widely used forms of Renewable Energy amongst others like Geothermal,Tidal,Biomass etc.While Hydro and Nuclear Energy are also considered by some to be Alternative forms of Energy,most governments do not count these two in their renewable targets.Wind Energy has been the dominant amongst the 2 in the last 2 decades as falling prices of Wind Power has made it more widely used.However the rapidly declining costs of Solar Energy has made it the faster growing of the two with 50% annual growth being seen in the last decade.Solar Energy also has a much larger potential than any other form of Energy.However its higher costs have inhibited its growth till now,however the entry of low cost Asian producers and fast technology innovation has already brought solar power on parity with fossil fuels in some places like Italy,Turkey,Hawai etc.

Solar Roofs are a niche area but is growing in popularity with the entry of more and more companies selling products tailormade for this area.What are Solar Roofs exactly - does it mean a Roof with Solar Panels installed on it or something else.Solar Roofs are not roofs where solar electricity is generated by putting in solar mounting/racking systems and mainstream solar panels,rather they are roofs where specialized solar products called solar shingles are installed.Solar Roofs can also mean a roof where Building Integrated Photovoltaic products are installed.Some companies make BIPV products like flexible solar panels or organic/dye solar cell panels ( these are niche companies).
