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.

Its Easy to Learn How to Make Solar Panels

Its Easy to Learn How to Make Solar Panels

you may also want to read : build solar panel
Plenty of people have been looking into installing solar panels in an effort to combat rising energy costs.  When most of these people see the prices of the professionally installed panels they realize it may not be a luxury they can afford.  There is an easier, more cost efficient way to harness power from the sun and that is to learn how to make solar panels for your self.

Any motivated do-it-yourselfer can learn how to make solar panels for their home, workshop or business.  When compared to the cost of purchasing and installing a pre-made solar energy system, learning how to make solar panels for your energy needs and the materials you need to execute the project are far less.  By learning how to make solar panels for yourself, you have greater control over the size and design of your system as well.
Once you have a quality manual and you have learned how to make solar panels, the supplies are fairly simple to find.  Most can be found at your local hardware store like, plywood, sheets of glass, and a roll of copper wire.  It is also easy to locate inexpensive solar or photovoltaic cells to use in your project.  Many are available over the Internet or you may have a retailer available locally.  One you’ve learned how to make solar panels and you have your supplies, it usually takes about a day to assemble a 100-watt panel.  This is the perfect amount of electricity to operate small appliances or a small workshop. 

The most important step is finding a quality manual with detailed instructions for learning how to make solar panels.  In many cases you get what you pay for, so don’t be afraid to spend a few extra dollars on a well-reviewed instruction manual.  Overall, the cost of the making your own panels is so low, the price of the how to guide is minimal-you will still be paying way less learning how to make solar panels on your own than purchasing a professionally installed system. 


With a little bit effort, you can be on your way to learning how to make solarpanels to meet your energy needs.  Then sit back and bask in the pride the next time the power goes out on your block.  Your lights will still be on because you learned howto make solar panels and your energy supply is still in your battery bank.

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.

What is Alternative Energy

What is Alternative Energy

There is a lot of energy that we can  harness if we only seek to research and develop the technologies needed to do so. We can get away from the fossil fuels and the old electrical grids by turning to alternatives to these energy sources.
