Renewable Energy is one of the most read about and discussed topics in the world however various misconceptions remain about the advantages and disadvantages of renewable energy.Note Renewable Energy is a a very large topic and encompasses many different alternative energy forms which have their own distinct pros and cons.A Better Way to understand and explain Renewable Energy would be to look at each different forms of Clean Energy like Solar,Wind,Nuclear,Hydro,Tidal,Biomass and Geothermal Energy.Renewable Energy itself compared to Fossil Fuel forms of Non-Renewable Energy has substantial advantages and some disadvantages as well the biggest of which is Cost.Also note Fossil Fuel Energy has got a massive established base,industry and lobby.

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.

The world’s total electricity generating capacity is around 4500 GW (2007 figures) which is expected to increase by 1.7% each year to rise to 7000 GW by 2035 according to EIA.USA is still the world’s largest electricity producing country with more than 20% of the world’s power capacity with around 1 Terawatts of Electricity Capacity.China has been rapidly adding capacity in the last decade and the second biggest electricity producing country with more than 700 GW more than 70% of which is from coal fired power plants.Japan,Russia and India are No.3,4 and 5 on the list with 280 Gw,220 GW and 159GW respectively.Europe is the third largest region in terms of electricity capacity with more than 800 GW.India is rapidly increasing capacity and is projected to be the No.3 in the list by 2020 as it looks to more almost treble its current electricity capacity of around 150 GW (in 2007).

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

The situation at the Fukushima Dai-Ichi power plant continued to be desperate as new fires and explosions rocked the nuclear plant.The utility which owns and operates the Nuclear Reactors Tepco said that the containment structure may have been damaged as smoke was seen from top of one of the reactors.70% of the Fuel Rods at Nuclear Reactor 1 and 33% at Reactor 2 have been exposed.This means that these fuel rods are not being cooled and may be melting leading to increased radiation poisoning hazards.New Fire broke out on the morning of 16th March at Reactor No.4 and containment chamber at Reactor 2 is damaged from Reactor 2.The problems at the Nuclear Plant seems to be increasing with no solution in sight.What is worse is that the 2 reactors No.5 and 6 which have been dormant all this time have all seen their temperature .increasing.Temperatures in the spent fuel rod cooling pools of the shuttered No. 5 and No. 6 reactors were rising as of 7 a.m. today to about 60 degrees Celsius (140 degrees Fahrenheit)

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.
