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.

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.

The backlash against the new and existing Nuclear Power Plants has started in different places around the world despite defiant expressions by Nuclear Plant Owners and Operators.While China and Italian utility Enel have said that they will go ahead with their billion dollar investment plans,Switzerland and Germany have put nuclear plant extensions on hold.Note Germany had extended the life of Nuclear Plants in the country by 10 years after extensive lobbying by the Nuclear Industry.This had led to huge protests from the Opposition Greens but the government had gone ahead in order to reduce Power Costs.However Merkel has been forced to eat humble pie and has said that a 3 month review will be done to check the safety of the Nuclear Reactors.Switzerland has also come out and put the plans for new Nuclear Reactors on Freeze.

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

This Nuclear Energy Disaster in the Age of Twitter and Facebook will vehemently increase the opposition to the setting up of big Nuclear Plants.The Radiation Leak and subsequent health hazards will make it impossible for a Nuclear Reactor to be located except in very remote areas like the Sahara Desert.NIMBY protests are going to almost kill the Nuclear Industry in the next decade at least in democracies.The Nuclear Industry will take a long time in establishing its trust amongst the citizens.Without Nuclear Energy,the other major forms of Renewable Energy ,Solar and Wind Energy have to gain.Already Switzerland and Germany are deferring the planning and extension of Nuclear Energy.Other countries are putting safety reviews.Note the costs of environment regulation and nuclear waste disposal are already quite high.This will make new nuclear plants uneconomical as they are already facing huge cost overruns . Ask Areva in Finland and Constellation in the US.

The Tsunami Nuclear Energy Disaster which is unfolding in Japan highlights that Nuclear Energy can cause some very serious damage though the safety of the nuclear reactors are highly touted in the media by the Nuclear Energy Industry.These Nuclear Plants in Japan are quite old but so are most of the Nuclear Energy facilities in the West.Most of these Nuclear Plants are susceptible to serious natural disasters like earthquakes and tsunamis.In case of a nuclear meltdown the radiation from the Nuclear Plants can not only cause more deaths and injuries from natural causes but also make the area around the Nuclear Plant uninhabitable for hundreds of years.India and China are on a major Nuclear Energy Building Spree even though their nuclear plants have faced minor accidents in recent years.With this Nuclear Disaster,the protests in the se countries are set to grow with NIMBY becoming the biggest hurdle.Already protests are being held in Jaitapur in Maharashtra over damage to the ecology,expect the Japan's nuclear reactor incident to basically kill this Areva-NPCIL plant.Nuclear plants in the US and Europe are already facing huge cost and time overruns.This new problem should cause those projects to also die off.

Wind Power has come under attack in the USA focused around the Cape Wind Project off the eastern shore.The project which was conceived over 10 years ago has not managed to still build the Wind Farm due to countless number of lawsuits filed for myriad reasons most of which are quite groundless.However some of the reasons have some solid facts behind the opposition to Wind Energy.Note Wind Energy unlike other forms of fossil fuel energy should have much less opposition however it is not so.Unlike Coal,Gas and Oil Energy it does not lead to increase in Greenhouse Gas Emissions and contribute to pollution.It does not lead to deaths of hundreds of miners each year nor has the danger of a catastrophic nuclear meltdown leading to death and disability of thousands.It also does not have the drawback of massive ocean pollution leading to an ecological disaster.However there are still protests against building of Wind Power Capacity and this article examines them in details.At the outset let me mention that advantages of Wind Power far outweighs the Disadvantages.
March 13, 2011
The Pros of Wind Energy far outweighs the Cons of Wind Power leading to massive amounts of wind power capacity being installed in almost every part of the world.Wind Power already generates majority of the electricity in countries like Denmark and almost 1/5th in countries with proactive renewable energy policies such as Spain,Germany and Portugal.Wind Power has great potential in USA,China and India which are driving the growth of Wind Power in the world.South America particularly Brazil are also showing strong interests in building up wind farms in the country.The recent increase in the price of oil and the dangers of Nuclear Energy further emphasize the importance of Wind Power Energy.

India had set up around 500 MW of Biomass Capacity by 2007 and has increased it by almost 150 MW since then to reach around 1 GW capacity today.Most of Indias' Biomass Electricity is being generated in Andhra Pradesh,Maharashtra,Tamil Nadu,Karnataka and Rajasthan.A lot of new capacity is being built in Punjab and Chattisgarh as well.India with a total biomass capacity of around 1 GW is planning to increase it by 10 times to 10 GW by 2020 by setting up a number of 1-2 MW biomass plants around the country.Around 400-600 acres of land are required to support 1 Mw of Biomass Capacity and 200-300 acres using energy intensive crops.This is much more than what is required for even thin film solar energy which is around 10 acres.The large land requirements make Biomass Energy Scalding a difficult proposition,however it has a great use in niche applications where there is a large amount of crop and animal residue/waste
Biomass Energy is clearly seeing a massive investment of private capital by a number of Green Energy companies.A number of these companies are backed by Private Equity Players.Almost all Sugar Companies in the country co-generate biomass power at their sugar plants.The size of the segment is quite large and has not been listed here.In India 3 types of companies are focused on biomass electricity - Sugar Companies,Rice Companies and Green Energy Utilities.The first 2 categories will be successful as their cost of feedstock is essentially zero while the the success of the third kind will depend on the management and execution.

The Costs of Biomass Energy Production fall in a very wide range because of the wide variety of feedstock it uses.The costs of biomass energy also depend on the distance of the feedstock from the biomass power plant.Great distances lead to the biomass plant being unfeasible.Also some forms of Biomass are more expensive than others.Urban Waste and Waste Wood are some of the cheapest forms of biomass available.Similarly,Biomass plants also can be built over a wide range of investments.Co-generation plants or CHP plants are the cheapest biomass plants while standalone biomass plants which can use a variety of feedstock are quite expensive in nature.Note unlike solar and wind power,the investments in power plants based on biomass are not fixed.Some of the technology like boilers and turbines for generating biomass energy are common industrial equipment.The costs of a biomass energy can also depend greatly on how the feedstock is procured,managed and used up by a biomass plant.A good manager of a biomass plant is very important to lower running costs of a biomass plant.
