Coal is one of the most important sources of energy for mankind providing an easy way to generate energy in a cheap manner.The relative abundance and low costs of using Coal has made it the the first choice of Fuel for building Power Plants in the world.Coal has huge importance as an Energy source and forms the most important raw material for Cement and Steel.Coal is also used in a variety of other industries like Paper,Aluminium,Chemical,Transportation and Pharma.However Coal also has huge negative consequences as it is the largest source of Carbon Emissions which happen during Coal Combustion.Coal Mining despite two hundred years remain as hazardous as ever resulting in thousands of deaths in India and China.Mercury,Arsenic and pollution of other harmful substances into the environment causes diseases and many deaths as well.However for countries like India and China there are little other alternatives and there is no conviction amongst policymakers to change their energy strategies as well.So the advantages of Coal are currently overpowering those of the Cons of Coal.This despite Coal being the dirtiest form of Energy and causing many deaths globally.The main reason for the cheapness of Coal is that the societal costs are not added on explicitly to the Price of Coal making it seem artificially cheap.

Coal is a dominant source of energy for humans accounting for almost for a quarter percentage of human energy consumption and majority of the global electricity production.However Coal is considered as the Dirtiest form of Energy as it leads to Air Pollution,Mercury Poisoning,Global Warming.Renewable Energy is considered as the solution with its non-polluting characteristics,energy security,freedom from peak everything.However Renewable Energy is way more expensive than Coal Energy making it difficult for Renewable Energy to take over Coal.However growing Global Warming Costs will weigh in the future making it inevitable that Green Energy catches up.Here is a list of the pros and cons of Green vs Black where Green represents Renewable Energy and Black represents Coal.Note Green Energy will ultimately win in the end,its only a question of how soon because if the realization comes too late then Climate Change might go far enough to cause catastrophic damage.

Toy Rentals are Companies that work on the concept of Libraries where Books are substituted by Toys,Children Books,Children Puzzles etc.Toy Rentals are a relatively new concept and have gained traction in different countries first though they are far from mass scale such as Car Rental Companies.The concept of Toy Rental Service or Toy Libraries is fast catching on in developing countries like India as well where the obvious value add to both companies and buyers make it a sharply growing industry.
Toy Rentals are a Green Concept as they help in reducing Waste,Promotes Sharing and Reduces your Carbon Footprint.It not only is Green but also has the following advantages
1) Reduces Cost of Ownership of Toys,Books,etc
2) Allows a Child to Play with new and unique toy not possible in a single ownership model
3) Reduces the Space Requirements in your House which also helps the Environment

Coal is the Biggest Contributor to Global Warming generating billions of tons of carbon dioxide during combustion.Coal is one of the most abundant fossil fuels available on earth and it is expected that Coal will last another 200 years.The mass usage of Coal and its deleterious effect on the environment makes Coal a controversial choice of Energy.Coal is responsible for 25% of Human Energy Consumption and is the largest producer of Electricity in the world.
Coal causes Human Deaths in the Thousands each year directly through Mining Deaths and Indirectly through Human Diseases like Lung Cancer,Mercury and Arsenic Poisoning.The costs of Coal are artificially low because these costs are passed onto society and not explicity added onto the cost of coal powered electricity or coal products like Steel and Cement.Reducing Coal Usage gradually is a big necessity but given the growing hunger for energy by India and China and lack of a Climate Agreement that looks unlikely in the near future

Coal is one of the cheapest and most important sources of energy, responsible for 41% of electricity productionworldwide. In many important countries like India,China,Germany,USA,Coal is the primary source of electricity and energy.Other smaller countries also heavily rely on coal for example Poland 94% , South Africa 92%, China for 77% and Australia for 76%.Coal has played this a pivotal role in the development of mankind and his progress into the Industrial Age.Coal is an essential raw material and fuel for important global industries like Cement and Steel.Different qualities of Coal are used for different purposes.For example coking coal with higher carbon percentage is used in Steel Production while Thermal Coal is used in Production of Electricity.It was during the Industrial Revolution in the 18th and 19th centuries that demand for coal surged. Coal is responsible for almost a quarter of the global energy production,41% of the Electricity Production and more than 60% for Steel Making.Here is a list of the Major Uses of Coal

China Wind Power Market has become the biggest in the world with more than 18 GW of capacity installed in one single year Note China has managed to double its capacity each year since 2005 and at the end of 2010 Wind Capacity totalled 44 GW which makes China the biggest Wind Power country in the world overtaking the USA.China has now got 7 of the Top 15 Global Wind Turbine Manufacturers and 2 of the Top 3 WTG Companies.China's Massive Demand for Energy has made power plants mushroom in the country where more than 70% of the electricity is met by Coal.Wind Energy still forms only a small part of the power mix at less than 7% of the total power capacity and serves only a fraction of the Kwh of electricity given the lower load factor of Wind Power.Note Wind Power has grown in China as its Advantages as a Clean Source of Energy far outweigh its Cons.However the rapid demand growth has made a top inevitable as a country can only install that many megawatts in a year.

TEPCO the owner and operator of the Damaged Fukushima Nuclear Plant reproted that its Onagawa Nuclear Power Plant in the Miyage Prefeture also leaked very small amounts of radioactive water.About 3.8 kgs of radiated water from one of the spent fuel rod pools spilled as three out of four external power supply units in Onagawa shut down leaving only one power source to cool the spent fuel. at the Nuclear Plant failed after the 7.4 Richter Scale Earthquake off the seas near Fukushima.The cooling systems have been restored and there is no more damage at the Nuclear Plant like Fukushima.Note the workers at the Damaged Dai-ichi were evacuated due to the Tsunami Warning issued in the aftermath of the Earthquake.These workers have again returned in their radiation fighting work at the Plant.USA said that it seems that the worst scenario of serious contamination from the Fukushima Nuclear Accident has probably passed.

India's Wind Energy Market is the 5th largest in the world and is the biggest renewable energy sector in India (non-hydro).Wind Power forms almost 70% of the Alternative Energy Capacity in the country and will have an important role to play to meet India's target of 10% Renewable Energy from Electricity by 2020.Wind Energy is very cost effective in terms of cost and is approaching Gas Electricity Prices.Combined with the favorable tax treatment,accelerated depreciation,subsidies by different sates,Wind Energy has become the favored Green Energy Sector for investment by large private sector companies.Wind Power Plants are increasing in number and scale as larger companies like Caparo enter the Wind Power Sector.Wind Turbine Manufacturers in India are fast expanding capacity and investment to capitalize on this opportunity.Suzlon remains the Bid Daddy of the Wind Industry in India,however a number of foreign and domestic Wind Turbine Manufacturers are giving it a run for its money.Global Wind Turbine Leaders like Siemens,Enercon,GE have started Wind Turbine Equipment Manufacturing in India in recent times to lower their costs.Here is a list of the Major Wind Turbines available in India of different types and capacities from the various Different Wind Manufacturers.

Wind Power Plants has seen a phenomenal growth of around 33% CAGR in the last 5 years and the total capacity at end of 2010 was 11800 MW with most of the capacity installed in the state of Tamil Nadu which is the largest state in terms of Alternative Energy Capacity in India.GWEC has set an ambitious target of 65 GW for Wind Energy in India by 2020 which means an addition of 5 GW each year which seems too high given the wind power potential in India is only around 65 GW.However using low wind speed sites may increase the potential besides the use of offshore wind power in India.A number of Wind Turbine Manufactures in India have set up facilities attracted by the domestic market with Suzlon being the biggest Wind Company in India.
The Indian Wind Energy already has the 5th largest installed capacity in the world and is set to grow at a rapid pace driven by investments from the private sector attracted by the generous wind subsidies from the state and central government in India.Most of the Installed Wind Capacity in India is located in the southern and industrial states of the country.The other states like UP,Bihar lacks sufficient Wind Energy Capacity despite having high power tariffs and substantial electricity deficits.It can be said that Wind Power in India is being developed only in the progressive states like Gujarat,Maharashtra and others.To continue to grow at the same rate,the industry needs to diversify geographically but that would need the backward state governments to pull up their socks.

Solar Carports are a relatively new Solar Energy Product compared to other Solar Products like Solar Heaters and Solar Cooking.Solar Carports are fast catching on as their dual use of protecting,shading a car as well as providing electricity to nearby offices and buildings.It makes use of real estate that would go waste so it provides a lot of value add besides helping in protecting the environment as well.

Seoul witnessed Radioactive Rain as winds blew from neighboring Japan which has witnessed the second biggest nuclear energy accident after Chernobyl.Though the the Rain contains cesium and iodine particles they are well within the safety limits according to the South Korean Nuclear Safety Regulator.South Korea has already protested against the lack of information about the Nuclear Emissions and the Deliberate Dumping of Toxic Seawater by TEPCO.However many schoolchildren stayed at home as worried parents were concerned about the impact of the radiation.China the other major close nation in proximity to Japan has also detected low levels of iodine in spinach in 3 provinces.China had earlier reported trace levels of radiation in Guangdong and Shanghai.Note Iodine has a very low half-life so that problem should not persist for long.However cesium is another matter as it can lodge inside human body and keep emitting for a long time internally.

American Superconductor (AMSC) which is one of the top rated wind stock in the US crashed by more than 40% as its largest customer AMSC is mainly a seller wind turbine core electrical components and full wind turbine electrical control systems (ECS).It has also made pilot sales of high capacity super conducting equipment to some customer like Tres Amigas.Sinovel which is also the 2nd biggest Wind Power Company in the world refused to take contracted shipments of wind turbine core electrical components and spare parts.The reason given was high inventory levels but the company failed to explain why Sinovel which is a multi billion dollar company has refused to pay AMSC for certain contracted shipments made in fiscal year 2010.Note $56 million in payments related to Fiscal 2010 quarters have been not paid to AMSC ( which would have been recognized as revenue).None of this was disclosed till now leading to a class action shareholder lawsuit against the company.It is quite perplexing why your largest customer will not pay you for past shipments and then cancel shipments as well.Is it because of some acrimony or is just Sinovel using its massive size to squash a small supplier.

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.

USA has been sorely lacking in the fight against Climate Change and Global Warming.Greenhouse Gas Emissions by the US has increased tremendously from 1990 the benchmark year when countries under Kyoto Protocol pledged to reduced their Carbon Emissions.However US has refused to do anything and has not even signed the Kyoto Protocol.The hopelessly rudderless leadership in the US has failed to pass any Clean Energy Laws like Cap and Trade ( not my favorite),Federal RPS etc.Some states have been showing proactive leadership like California despite massive opposition by the powerful oil and gas lobby (Valero,Koch Brothers).Their efforts are being stymied by the very rich who don't care about global warming as they can easily use their money to mitigate any affect on them and the powerful fossil fuel lobby with their thinktank puppets.

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.
April 4, 2011
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.

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.
