Developing Nuclear Power as Alternative Energy

Developing Nuclear Power as Alternative Energy


Many researchers believe that harnessing the power of the atom in fission reactions is the most significant alternative energy resource that we have, for the fact of the immense power that it can generate.

Nuclear power plants are very “clean-burning” and their efficiency is rather staggering. Nuclear power is generated at 80% efficiency, meaning that the energy produced by the fission reactions is almost equal to the energy put into producing the fission reactions in the first place. There is not a lot of waste material generated by nuclear fission—although, due to the fact that there is no such thing as creating energy without also creating some measure of waste, there is some. The concerns of people such as environmentalists with regards to using nuclear power as an alternative energy source center around this waste, which is radioactive gases which have to be contained.

The radiation from these gases lasts for an extraordinarily long time, so it can never be released once contained and stored. However, the volume of this waste gas produced by the nuclear power plants is small in comparison to how much NOx (nitrous oxide—that is, air pollution) is caused by one day's worth of rush-hour traffic in Los Angeles. While the radiation is certainly the more deadly by far of the two waste materials, the radiation is also by far the easier of the two to contain and store. In spite of the concerns of the environmentalists, nuclear power is actually environmentally friendly alternative energy, and the risk of the contained radiation getting out is actually quite low. With a  relatively low volume of waste material produced, it should not be a difficult thing at all for storage and disposal solutions for the long term to be developed as technology advances.

The splitting of an atom releases energy in the forms of both heat and light. Atomic power plants control the fission reactions so that they don't result in the devastating explosions that are brought forth in atomic and hydrogen bombs. There is no chance of an atomic power plant exploding like a nuclear bomb, as the specialized conditions and the pure Plutonium used to unleash an atomic bomb's vicious force simply don't exist inside a nuclear power plant. The risk of a “meltdown” is very low. Although this latter event has happened a couple of times, when one considers that there are over 430 nuclear reactors spread out across 33 nations, and that nuclear reactors have been in use since the early 1950s, these are rare occurrences, and the events of that nature which have taken place were the fault of outdated materials which should have been properly kept up. Indeed, if nuclear energy could become a more widely accepted form of alternative energy, there would be little question of their upkeep being maintained. Currently, six states in America generate more than half of all their electrical energy needs through nuclear power, and the media are not filled with gruesome horror stories of the power plants constantly having problems.

What to Know Before Purchasing Home Solar Electricity
read carefully before purchasing
Getting home solar electricity is more affordable today than 10 years ago.  In fact, many state governments are currently offering tax rebates to persons that choose to convert to home solar electricity.  If installing a photovoltaic system to supply your home solar electricity is too far out of your financial abilities, there are also programs available to purchase your utilities from an accredited green energy supplier.  Green energy suppliers offer only utilities fueled by renewable resources, such as solar electricity, hydroelectricity and wind generated electricity.  However, if you made the decision to switch to solar electricity for your home it is important to determine your electricity needs before you start shopping.

The first thing to determine is how much power you will need from your home solar electricity system.  Different arrays and solar panel set-ups offer different wattage outputs.  Take the time to determine your average daily electricity usage.  You want to achieve a number that includes the entire year and affords for the different amount of energy used during winter and summer months (more lights, heaters, air conditioners). 

When shopping for the right photovoltaic system to supply your home solar electricity definitely research the quality of the product.  A product offering 13% efficiency and a lifetime warranty will be far more valuable than the panel offering 15% efficiency and a one-year warranty.  Ask neighbors, friends and even strangers currently using home solar electricity, to learn more about the differences in systems.  Sufficient time should also be spent interviewing installers and researching manufacturers as well.

A final decision needs to be made as to what kind of system you would like to use to supply your home solar electricity.  There are generally three types of solar panel systems used to supply home solar electricity.  The first type is a grid-tied system in which your solar panels are tied into your current power meter.  You are using both electricity supplied by your panels and your supply is then backed by electricity from your electric company.  The second available solar panel system for supplying home solar electricity is a grid-tie with battery backup.  With this system you are collecting electricity from you panels, filling your batteries for emergencies and then the excess is sent back to the electric company through your meter.  The final system is a stand-alone system.  Very similar to the grid-tied system with battery backup except that you are completely disconnected or maybe never connected to a major utility provider for your area. 


Once you educate yourself on providing your home solar electricity, you are probably ready to start shopping.  Remember that converting to home solar electricity is an investment and you will reap the rewards over time.  And don’t forget the pride you will have with reducing your carbon footprint by converting to home solar electricity.   

Can Anyone Live Off The Grid?


 Can Anyone Live Off The Grid?

Live Off The Grid
you want to be in a house like this ?

When you talk about alternative energy and living off the grid, a lot of people feel instantly that they will have to give up most of their modern amenities to live in such a fashion.  Many more think this is an endeavor solely for granola loving hippies, whose modest ways coincide with fewer technologies, TVs, ACs, etc.  The truth is, living off the grid is a possibility open to anyone.  Granted, you may have a larger investment if you are powering three chest freezers and all high-energy appliances, but this would simply mean you need a larger system.

The increased demand for renewable energy technology has led to the development of more efficient and easy to use components to make living off the grid a reasonable option for anyone willing to be mindful of their energy consumption. 

Using renewable energy sources to produce electricity is a fairly simple process.  You need a power source-sun, wind or water-from which you will harness a low voltage direct current that is then converted, using an inverter, into usable house current (AC).  Excess current generated by your system is stored in battery banks where it can be retrieved during more high demand times or times when the direct energy source is unavailable. 

Living off the grid with renewable power resources is almost completely automated as well.  Except for the maintenance of your batteries, there is almost no special attention needed, other than monitoring your energy use to make sure you do not exceed your supply with your demand.  The key to success in living off the grid is making sure you size your system to meet the demand of your energy needs. 


Living off the grid can be an exhilarating experience.  The feeling of energy freedom is like no other and you can be proud of your efforts to combat global warming and best of all, you may never have to worry about a power outage again.  It is important to conduct your research and determine which alternative energy sources will work best for you in your geographical area, but it is definitely worthwhile to learn how to live off the grid and feel the rush of freedom being off the grid can give.

Solar Energy Collecting as an Alternative Energy Source

Solar Energy Collecting as an Alternative Energy Source


solar cellPhotovoltaic cells—those black squares an array of which comprises a solar panel—are getting more efficient, and gradually less expensive, all the time, thanks to ever-better designs which all them to focus the gathered sunlight on a more and more concentrated point. The size of the cells is decreasing as their efficiency rises, meaning that each cell becomes cheaper to produce and at once more productive. As far a
s the aforementioned cost, the price of producing solar-generated energy per watt hour has come down to $4.00 at the time of this writing. Just 17 years ago, it was nearly double that cost.

Solar powered electricity generation is certainly good for the environment, as this alternative form of producing energy gives off absolutely zero emissions into the atmosphere and is merely utilizing one of the most naturally occurring of all things as its driver. Solar collection cells are becoming slowly but surely ever more practical for placing upon the rooftops of people's homes, and they are not a difficult system to use for heating one's home, creating hot water, or producing electricity. In the case of using the photovoltaic cells for hot water generation, the system works by having the water encased in the cells, where it is heated and then sent through your pipes.

Photovoltaic cells are becoming increasingly better at collecting sufficient radiation from the sun even on overcast or stormy days. One company in particular, Uni-Solar, has developed solar collection arrays for the home that work well on inclement days, by way of a technologically more advanced system that stores more energy at one time during sunlit days than previous or other arrays.

There is actually another solar power system available for use called the PV System. The PV System is connected to the nearest electrical grid; whenever there is an excess of solar energy being collected at a particular home, it is transferred to the grid for shared use and as a means of lowering the grid's dependence on the hydroelectrically-driven electricity production. Being connected to the PV System can keep your costs down as compared to full-fledged solar energy, while at once reducing pollution and taking pressure off the grid system. Some areas are designing centralized solar collection arrays for small towns or suburban communities.

Some big-name corporations have made it clear that they are also getting into the act of using solar power (a further indication that solar generated energy is becoming an economically viable alternative energy source). Google is putting in a  1.6 megawatt solar power generation plant on the roof of its corporate headquarters, while Wal Mart wants to put in an enormous 100 megawatt system of its own.

Nations such as Japan, Germany, the United States, and Switzerland have been furthering the cause of solar energy production by providing government subsidies or by giving tax breaks to companies and individuals who agree to utilize solar power for generating their heat or electrical power. As technology advances and a greater storage of solar collection materials is made available, more and more private investors will see the value of investing in this “green” technology and further its implementation much more.

Alternative Energy sources for the Home

Alternative Energy sources for the Home

alternative energy sources for the home
Thêm chú thích

The trend toward homes that are powered by alternative energy sources, ranging from wind turbines and solar collection cells to hydrogen fuel cells and biomass gases, is one that needs to continue into the 21st century and beyond. We have great need of becoming more energy independent, and not having to rely on the supplying of fossil fuels from unstable nations who are often hostile to us and our interests. But even beyond this factor, we as individuals need to get “off the grid” and also stop having to be so reliant on government-lobbying giant oil corporations who, while they are not really involved in any covert conspiracy, nevertheless have a stranglehold on people when it comes to heating their  homes (and if not through oil, then heat usually supplied by grid-driven electricity, another stranglehold).

As Remi Wilkinson, Senior Analyst with Carbon Free, puts it, inevitably, the growth of distributed generation will lead to the restructuring of the retail electricity market and the generation, transmission and distribution infrastructure. The power providers may have to diversify their business to make up for revenues lost through household energy microgeneration. She is referring to the conclusions by a group of UK analysts, herself included among them, who call themselves Carbon Free. Carbon Free has been studying the ever-growing trend toward alternative energy-using homes in England and the West. This trend is being driven by ever-more government recommendation and sometimes backing of alternative energy research and development, the rising cost of oil and other fossil fuels, concern about environmental degradation, and desires to be energy independent. Carbon Free concludes that, assuming traditional energy prices remain at their current level or rise, microgeneration (meeting all of one's home's energy needs by installing alternative energy technology such as solar panels or wind turbines) will become to home energy supply what the Internet became to home communications and data gathering, and eventually this will have deep effects on the businesses of the existing energy supply companies.

Carbon Free's analyses also show that energy companies themselves have jumped in on the game  and seek to leverage microgeneration to their own advantage for opening up new markets for themselves. Carbon Free cites the example of electricity companies (in the UK) reporting that they are seriously researching and developing ideas for new geothermal energy facilities, as these companies see geothermal energy production as a highly profitable wave of the future. Another conclusion of Carbon Free is that solar energy hot water heating technology is an efficient technology for reducing home water heating costs in the long run, although it is initially quite expensive to install.  However, solar power is not yet cost-effective for corporations, as they require too much in the way of specialized plumbing to implement solar energy hot water heating. Lastly, Carbon Free tells us that installing wind turbines is an efficient way of reducing home electricity costs, while also being more independent. However, again this is initially a very expensive thing to have installed, and companies would do well to begin slashing their prices on these devices or they could find themselves losing market share.
