List of Solar Companies By Country (Japan, Korea, China, Germany, India and USA)

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.

Disadvantages of Renewable Energy – Drawbacks of Different Alternative Energy Sources

The Biggest Disadvantage of Renewable Energy is the relatively higher cost of most forms of alternative energy compared to fossil fuel sources of energy.This has prevented the higher penetration of clean energy as compared to the non-renewable sources of energy.Also the massive old energy lobbies have successfully used their massive influence and power to inhibit the growth of renewable sources of energy.The recent lobbying by oil and gas firms like the Koch Brothers and Valero is quite pertinent.Note the oil and gas lobbies receive almost 10 times the subsidy received by clean energy sources like wind and solar despite their massive established bases.

Advantages of Green Clean Renewable Energy – Complete List to Solar,Wind,Biomass Geothermal,Hydro,Nuclear and Tidal Energy Pros

The importance of Clean and Renewable Energy is growing driven by the twin factors of increasing fossil fuel prices and Global Warming.Other factors contributing to the importance and growing use of Alternative Energy is national energy security as geopolitical tensions in major oil and gas countries grows by the day.Also renewable sources of energy like solar energy promote the democratization of energy production which is centralized by power utilities today.There are a number of alternative sources of energy such as solar,wind,geothermal,tidal,hydro and nuclear energy.Some people may not consider nuclear and hydro energy to be green but it is a fact that these 2 energy sources do not produce GHG emissions and cannot be classified as fossil fuels sources.Each clean energy source has its own advantages and many of the pros overlap with each other as well.However each Green Energy source has its unique benefits which define and separate it from the other clean sources.While Renewable Energy advantages over Non-Renewable can be easily be understood as

Pros of Nuclear Energy – Nuclear Power Benefits under the Fukushima Cloud

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.

Hydroelectricity Costs – Not as Simple as Dollars per Kilowatthour

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 – Definition,Guide to this Electricity Policy,Fake Feed in Tariffs,Importance of Solar Net Metering

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.

Reactor 1 "Recritical" as Radioactive Chlorine Detected, Japan thinking Concrete Burial,Radiation increases to 4385 legal limit in Seawater

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 – Competition and Cooperation between the these Dominant Renewable Energy Sources

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.

In Japan Dangerous Level of Radioactivity Flares up Contaminates SeaWater,Greenpeace detects harmful radiation in Itate village 40 km north of Fukushima,calls for expanding the 20 km evacuation zone which government rejects,TEPCO asks for French Areva EDF CEA help

Dangerous levels of radiation has been detected in the water around the reactors as the Japanese government says that a partial meltdown has occured.While there is no confirmation about cracks in the pressure and containment vessels around the reactors,the radiation in the water inside Unit 2 has tested at radiation levels some 100,000 times normal amounts.Workers also discovered radioactive water in the deep trenches outside three units, with the airborne radiation levels outside Unit 2 exceeding 1,000 millisieverts per hour _ more than four times the amount that the government considers safe for workers.TEPCO officials said Sunday that radiation in leaking water in Unit 2 was 10 million times above normal.TEPCO has been giving confusing figures for radiation making it all the more difficult in understanding the gravity of the nuclear crisis.Note this disaster is only second to Chernobyl in its scale of radiation destruction.Tokyo and other parts have reported intermittently about high radiation in water and air.A ship from Mitsui was recently turned back from a Chinese port because of high levels of radiation.

Taiwan Solar Energy Challenging China – Taiwanese Solar Cell,Wafer,Panel,Inverter Manufacturers following the Semi Success Path

The Taiwanese Solar Industry has become the 2nd largest in the world following in the footsteps of China.Taiwanese Solar Industry has a longer history than the Chinese with Solar Cell Makers Motech and E-Ton establishing themselves globally way back in 2006.However the steep fall in solar panel prices following the Lehman crisis had led to losses for these companies as the Chinese companies surged ahead using their low cost manufacturing.The crisis also led to the emergence of newer Taiwanese companies like Gintech,Neo Solar which are growing at extremely fast rates.Note Taiwan is a hub of semiconductor manufacturing with leading companies like TSMC,AUO,UMC,HTC etc.Solar Industry uses many of the same technologies,raw materials and techniques common to semiconductor and Display Panels Production giving Taiwanese firms a natural advantage.Taiwan has been predominantly present in the crystalline Solar Cell part of the supply chain and lacks a big manufacturer of polysilicon ( though a facility has been started).The lack of vertical integration has also made the costs of the Taiwanese industry higher.The entry of large companies like AUO,TSMC has further increased the competition in the Taiwanese market.Note Taiwan's government has also promoted the use of solar energy in the country through the use of a Feed in Tariff program.

Nuclear Radiation Levels and Effect on Human Health as Sieverts increase in Japan – What you need to Know

The explosion and fire at the Japanese Nuclear Plant in NorthEast of Japan has led to the release of a small nuclear plume above the reactors.The southern winds have caused this radiation to spread in many of the prefectures in Japan and cesium and other radioactivity has been detected in the capital of Tokyo.Note Radiation does not affect the human body in small doses as radiation is present in our everyday lives at well.However the increase in radiation concentration can lead to severe health hazards and in extreme cases even death.It is almost impossible to escape radiation effects unless one has special nuclear,biological warfare protective equipment.Note Radiation in Japan is still at quite mild levels and seems unlikely to cause any major health hazard.Radiation will need to increase about 1000 times from the current level for the situation to become serious as of now
