Islands mostly are depended on diesel generators for their electricity requirements which is considerably costlier than the normal coal,hydro,gas and nuclear forms of energy.Unless you are Saudi Arabia and can get oil at $4/barrel,the price of electricity from oil based energy sources is one of the costliest.Hawaii in USA pays around 30c/KwH for electricity because of the high cost of transporting and buying fossil fuels for its power plants.These islands have a huge incentive in moving towards renewable energy because it not only reduces costs,carbon emissions but also helps in energy security.Hawaii has installed a large number of wind farms,is building a big energy storage facility and promoting other alternative energy forms like solar as well.Hawaii Feed in Tariff has been implemented despite opposition by the utilities.

PV Solar Cells or Photovoltaic Solar Cells are the building blocks of Solar Panels which are used to generate electricity from the Sun in residential or commercial establishments.Solar Cells are made of crystalline silicon the same substance that is used to make semiconductors which go into making of electronic products.Note Thin Film Solar Cells are not found for practical purposes as Thin FIlm Solar Production generally is a one step continuous process in which the whole solar panel is produced.On the other hand c-Si production is a 5 step process in which Solar Cells is the intermediate product of the 4th stage and goes as input to making of solar modules/panels.Solar Cells can be bought and made into Solar Panels as PV Solar Cells don't have much of a standalone usage.Note Buying Solar Cells and making DIY Solar Panels does not make much sense as it adds little value and does not save money.You are better off buying Solar Panels from affordable solar panel manufacturers.

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.

Increasing Oil Prices is the biggest Achilles Heel of the Indian Economy heavily dependent on imported oil products.The government will have to either raise the prices leading to adding fire to the already high inflation or compensate the badly bleeding half privatized Oil Companies like IOC,BPCL and HPCL.These companies generally make massive losses despite having private investors apart from the government.Compensating these losses would lead to a higher fiscal deficit which would add to the inflation pressures anyway.Note a recent survey revealed that the Indian Middle Class has cut its expenditure on shopping,eating out and entertainment by a whopping 65% due to the high inflation.However the Indian Stock Market has seemingly discounted all these factors going up by 10% in 10 days on the back of a global rally.Bernanke Fueled Cheap Money is Circulating Hungrily across the Globe and currently India seems to be the fashion trend of the month.Note these hot money flows can reverse equally quickly leading to a sharp market crash just like the Jan-Feb one as fundamentals hardly support this kind of rally.With government intervention and distortions becoming the overriding factor in the stock markets,Free Markets and Fundamentals have taken a backseat.

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

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.

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.

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 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.

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.

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.

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).

Solar Panel Manufacturers globally have kept on increasing due to the fast growing nature of the industry and low entry barriers.However most of the solar panel manufacturers have high costs and low quality.Most of these producers have little growth prospects and are a bad choice to buy from as they might go bellyup.This would lead to a void of the 25 year warranty of the solar panels.So it makes sense only to buy from the biggest and best solar manufacturers in the world.Solar Panel Manufacturers are present in most parts of the world with Korea,China,Taiwan,USA,Japan and Germany dominating.However small solar panel producers are also present in most countries like Spain,Greece,India etc.Solar Panels are of mainly 2 type - crystalline and thin film.Most of the solar panels produced today are of the crystalline type and are mostly used in residential rooftops.Thin film panels are mostly used in large ground solar power plants.Thin film solar panels are of lower efficiency and are lower priced as well.However falling costs of crystalline solar panels has led to their increasing dominance.

Solar Power has been the fastest growing energy source in the last decade showing a compounded annual growth of over 50%.In 2010 alone,solar energy demand grew by almost 150% beating the most optimistic forecasts as costs kept on declining for this renewable energy source.While Solar Power continues to be one of the most expensive forms of energy,it is also the energy source where the costs are declining rapidly.However detractors of this alternative energy source keep pointing to its drawbacks.Note the Disadvantages of Solar Power are far overpowered by the Pros of Solar Energy.However the drawbacks of Solar Power do exist.Here are the Disadvantages of Solar Power .
March 28, 2011
Free Solar Panels don't exist just as Free iPads don't exist.Some websites and companies advertize free solar power or free solar panels based on government subsidies.Note even these free solar power offers are not completely free as they have a payback periods depending on how much government subsidies are given.Nobody is going to give you a free solar panel or a free iPad without a catch.

The Green Party in Germany has continued its massive upsurge in popularity in Germany winning a huge slice of votes in key German states which have gone to polls recently.Green Party in Germany which is founded on the principles of social justice, reliance on grassroots democracy nonviolence, and an emphasis on environmentalism has remained a fringe player.However the recent backlash against the nuclear power plant extension by Merkel,the planning on high speed rail in Stuttgart and the frustration with the foreign and Euro policies of the ruling CDU has led to huge gains.Note Green Parties are found in most European countries though they remain non-existent in major Anglo-Saxon countries.However the recent Japanese nuclear disaster may give a fresh impetus as global warming effects continue to increase and nuclear energy comes under attack.Mass protests against nuclear power continue to be held in different cities in Germany

While Chinese pure play solar panels companies have already captured a majority of the global solar module market,the entry of newer Chinese players into the solar energy market refused to stop.China's 5 largest state owned utilities have already made their presence felt in the Chinese domestic solar installation market by bidding extremely low to win projects under the Chinese Solar Subsidy program.Automotive companies like BYD have also announced a big investment into solar panel manufacturing while Hanlong and Bluestar Groups have decided to invest in the CPV and Polysilicon sectors respectively.

Coal Mines in Indonesia,Australia,Africa and North America are selling like hot cakes as Indian,Chinese companies as well as mining conglomerates like Rio Tinto,Vale,BHP Billiton fight to secure raw materials.Note India and China are consuming huge amounts of coal to power their thermal plants.While China consumes a monstrous 3 billion tons,Indian demand is rising at more than 10% a year though on a smaller base.Coal is the cheapest form of power despite its polluting and health hazardous affect.Though Coal Plants in Developed countries are becoming much more expensive to build due to taxes and opposition by environmental groups,there is no stopping their furious growth in countries like China and India.Though India too faces some environmental opposition,massive ultra mega power plants with capacity of 4000 MW are getting built by new Indian private utilities

German's Solar Energy Market is the biggest in the world by a fair margin.Germany installed almost 6 gigawatts of solar panels in 2010 taking the total installed capacity to almost 16 GW which is 40% of the world's total installed solar capacity.Note Germany's Photovoltaic Solar Electricity now forms almost 10-15% of the total electricity production in the country at peak time.Note Germany's solar industry got a renewed boost when 7 old nuclear plants were shutdown following Japan's Fukushima Nuclear Disaster recently.Previously Germany had decided to extend the operating life of its Nuclear Plants despite stiff opposition.Germany Solar Subsidy which is framed under the Renewable Energy EEG law has made Germany one of the world's leaders in Wind,Solar and Biomass Energy.Germany's Manufacturing Industry has benefited from the strong domestic market with many of the world's top solar panel companies located there.Solar equipment,inverters and cell companies are also present in large numbers.Recently Germany amended its Feed in Tariff Law to slowdown the exponential growth in solar panel installations.This is over and above the regular reduction in solar subsidies done each year.

Geothermal Energy is regarded as a poor cousin to its more glamorous cousins Wind and Solar.Geothermal Energy Capacity has been installed and the growth rate is a pathetic 3-4% compared to the over 50% CAGR seen for solar energy and around 30% for Wind Energy.However Geothermal Energy possesses one attribute that the others do not.Its 24 hour generation capability is a massive plus compared to the intermittent nature of Wind and Solar Energy.However long project development time and large capital investments have deterred fast growth in geothermal energy in the world.However some countries like Iceland,Indonesia,Philippines and USA have a strong geothermal energy industry.Note Geothermal Energy has massive use as a heating source for homes and offices,however this article mainly talks from the view of Electricity Generation.
