The importance of Clean and Renewable Energy is growing driven by the twin factors of increasing fossil fuel prices and Global Warming.Other factors contributing to the importance and growing use of Alternative Energy is national energy security as geopolitical tensions in major oil and gas countries grows by the day.Also renewable sources of energy like solar energy promote the democratization of energy production which is centralized by power utilities today.There are a number of alternative sources of energy such as solar,wind,geothermal,tidal,hydro and nuclear energy.Some people may not consider nuclear and hydro energy to be green but it is a fact that these 2 energy sources do not produce GHG emissions and cannot be classified as fossil fuels sources.Each clean energy source has its own advantages and many of the pros overlap with each other as well.However each Green Energy source has its unique benefits which define and separate it from the other clean sources.While Renewable Energy advantages over Non-Renewable can be easily be understood as
Nuclear Energy is facing a global backlash after the Fukushima incident in Japan as countries race to review their existing nuclear reactors.Nuclear Power had been enjoying a Renaissance in the 21st century as the Chernobyl and Three Mile Radioactive incidents faded from public memory.China is the principal driver of growth constructing reactors at a rapid clip to meet its growing needs with thermal power fast reaching a saturation point.Other growing developing countries like India,Vietnam are also planning to heavily invest in nuclear plants.However all those plans may change as the Japanese earthquake shakes up the nuclear energy industry more than the landmass in Japan itself.Note despite the catastrophic tails risks of nuclear power,it is not going to go away soon due to the large installed base and no fast substitutes available.Note more than 430 nuclear reactors are currently operational globally today and lots more on the drawing board.Note Nuclear Power accounts for around 18% of US electricity capacity and 30% plus for Europe,Japan and Korea.France is the leader with 80% of the electricity generated coming from nuclear fission.Here is a list of the Pros of Nuclear Energy.
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.
The French President Sarkozy has become the first international leader to visit Japan after the Fukushima Dai-ichi Nuclear Disaster which has simmered for more than 3 weeks.Japan and France do not have a strategic relationship like USA and Japan does nor do these countries have shown great friendship in the past.So it surprising why Sarkozy has gone to Japan on such a short notice to pledge all French help to the Japanese in the wake of the radioactivity leaking from the reactors in northern Japan.Note France has been the leader in the Libyan no fly zone as well calling for Western intervention in a mostly domestic civil war.France has not got too much involved in other civil wars raging in the Middle East.It has been selective over it choice for jumping up and down over human rights.The glaring Western and French silence over the Saudi invasion of Bahrain and violent suppression of its citizens by the Middle Eastern dictators tells of a hypocrisy.
Hydroelectricity is one of the largest sources of energy accounting for roughly 20% of the worldwide demand of electricity with around 800 GW of capacity installed.There is considerable potential still left and developing countries like India and China can be expected to install another 500 GW over the coming years.Hydroelectricity is very important as it does not lead to GHG emissions and contribute to global warming.It also does not have the drawbacks like other renewable energy forms of high costs and intermittency.The advantages of hydroelectricity are substantial enough to far outweigh any disadvantages.But like nuclear energy,hydro power has some tail risks which can lead to catastrophic damage.The costs of hydroelectricity are not a simple function of dollar costs.It should also take into account the massive displacement costs in case of massive hydro dams,the loss of ecology and potential tails risks which can lead to massive payments.
Net Metering is a very important Electricity Policy for the promotion of Distributed Electricity Production from Renewable Energy Sources especially Solar Energy.All consumer establishments connected to the power grid have an electricity meter installed which measure the amount of power consumed during a month in Kilowatt Hours (KwH) which is known as one unit.The power utility compiles the data for power consumption during 1 month and sends a bill which is usually the number of KwH multiplied by the retail electricity rate which can vary widely from 10c/KwH to around 35c/KwH depending on the geography.
