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.

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.

Biomass Power Plants are increasing rapidly as the costs of fossil fuels go up and the need for renewable energy is increasing.Biomass Power is attractive because of its clean character and supplies a large portion of the energy needs in rural communities.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 has a number of advantages over conventional forms of energy and depending on the feedstock cost can be generated at prices on par with fossil fuels.Biomass Energy also leads to higher energy security as biomass is almost always secured locally.

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.Till the 19th century biomass energy used to account for 70% of the world's energy consumption and still accounts for around 10% of the world consumption.In developing countries the share of biomass energy is still quite high at 30% and it is the major source for energy for rural and backward communities.Biomass primarily consists of

India has around 300,000 Telecom Towers around the country , a large portion of which is not connected to the electricity grid.Another large portion does not have access to reliable electricity implying they have to install backup power systems in order to run without interruptions.Diesel Generators have been the choice of telecom operators despite their high carbon imprint.This is because of the ease of buying and installing diesel generators as well as the lower fuel costs as the government in India heavily subsidizes diesel.Note India's Fossil Fuel Subsidies have led to hundreds of distortions in the economy.Corruption,Pilfering,Adulteration is carried out on a large scale due to government subsidies.In fact a senior government official was burnt alive by the Kerosene Mafia a direct outcome of this subsidy policy.But that is a separate issue.

France has had a rocky relationship with solar energy.Unlike other European countries France gets a huge amount of electricity from renewable sources namely nuclear energy.Its electricity prices are one of the lowest and it even exports electricity to neighbors.So the driver for increasing solar electricity is quite low in France compared to others like Spain and Italy.However France has seen a massive boom in solar installations in 2010 making it the 7th largest market in the world.France installed over 720 MW of solar in 2010 and faces a massive backlog of applications.The government got overwhelmed and called a sudden stop to all applications.The French government stupidly blamed Chinese solar panels for the solar deluge when it was its faulty solar Feed in Tariff Policy which was too generous.

India may uses the planned $500 million to $1 Billion in Coal Taxes it expects to generate every year to build transmission lines for renewable energy.Note one of the main impediments for renewable energy is the lack of transmission capability on part of utilities to move clean energy from remote areas to urban demand centres.USA faces an acute problem in this regard and faces a massive debate on how to fund the power grid from windy areas to cities.India too faces a problem in this regard as renewable energy plants mainly wind and solar are to built in remote locations.Note India's Power Grid is very inadequate as large parts of the country lack electricity due to lack of distribution networks.

India is set to see a massive growth in solar energy in the next decade with the 81 MW of Solar Capacity expected to reach at least 20000 MW by 2022 if not more.India's JNNSM Policy and push for renewable energy by states like Gujarat,Maharashtra and Rajasthan should see massive investments in solar PV installation.While there are already solar cell and panel production,India lacks a strong base for manufacture of solar inverters which can cost upto 10% of the total cost of a solar project.

Solar Panel Prices have decreased at a jaw dropping 50% in the last 2 years and will probably decrease 10-15% more in 2011.That is an astounding number given the increasing energy and electricity prices being faced around the globe.Though solar energy is costlier than other forms of energy,it starts on a low base.With 2010 solar growth pegged at more than 100% and 16 GW of solar panels installed,Solar Energy is starting to become more mainstream.Like Solar,the entry of Chinese players has decreased the cost of Wind Energy as well.Despite increasing input steel and copper prices,wind turbine prices have declined.Stiff competition amongst Chinese WTG companies has made the price of a Wind Turbine go as low as $600,000-700,000 in China.This has brought a depression in prices in other places in the world as well.

Carbon Capture and Sequestration (CCS) has been mooted as one of the main weapons against climate change.With little alternative to Coal based power generation,CCS is touted as a temporary solution.However CCS as a global warming solution is like putting lipstick on a pig.The technology for CCS remains immature at best and even the biggest users of coal,the Chinese utilities have ruled out using CCS before 2015.Though big pilot projects have been announced in Australia,USA and UK,CCS is not a serious option as far as dealing with climate change.This however has not prevented companies from playing in this area.Toshiba is the latest company to join the CCS fray hoping to set up a 5 MW pilot plant in JV with India's biggest power utility NTPC.

United Kingdom is one the worst countries in the world in terms of its commitment towards Global Warming.Like Canada and USA,UK has been a notable laggard in the Green Energy area.It has one of the smallest percentages of its Energy being derived from clean sources.The government has not changed its policies too much as well despite its "green posturing".Solar FIT cuts which started in April 2010 were put under review by the authorities in as little as 6 months .This was despite only 10 MW of solar installation a month compared to the 500 MW average for Germany.In offshore wind power,UK is regarded as the leader with the largest installed capacity.However the growth in even Wind Energy has been slow and halting.Also offshore wind power is not the most mature of green technologies out there,so don't expect any miracles in Renewable Energy growth through this source.

China using its massive foreign exchange horde to buy commodity assets around the world is an old story by now.It is now also getting into the act in the Green Energy area as China's state owned chemical group Blue Star has bought Norwegian environment chemical company Elkem from the Orkla conglomerate.Elkem is one of the largest silicon metal producers in the world and makes a solar grade polysilicon through a specialized low cost process.Orkla which is also the 40% owner of one of the world's largest silane and polysilicon producers Renewable Energy Corporation (REC) had been looking out for some time to sell Elkem.China has not been a big producer of polysilicon which is the main raw material for producing silicon based semiconductors and silcion based solar panels.The massive demand for polycrstalline modules has resulted in it being the main demand driver for polysilicon.

A2Z Maintenance and Engineering Services is a Private Equity Promoted Facilities Management,Waste Management and EPC Company which is getting into the business of biomass energy.Company has fixed a price band at Rs 400-410 comprising of fresh issue of Rs 675 crore (~$150million) by the company and an offer for sale of upto 4.5 million shares by the selling shareholders.Note Renewable Energy in India has a bright future with around 5 GW of Renewable Energy Capacity to be installed per year over the next decade.However Biomass Energy may not be the best area considering the considerable expense and uncertainty in acquisition of feedstock.The Company already operates in 3 distinct sectors namely
Summary
A2Z is very similar in nature and valuation to VA Tech Wabag which did a successful IPO recently.The margin profile,growth and management is very similar.As such A2Z is a decent company however its not a compelling buy given the valuation.Note Biomass Energy is a tough sector to operate in and Orient Green Power has done badly since its IPO without having done anything badly as such.A2Z given the overall qualitative and quantitative factors seems a good stock at fair valuation.This makes the company a decent one to buy.
