The concept of energy independence first entered the national consciousness in the early 1970’s, when the unstable nature of reliance on foreign oil was made all too obvious by a series of embargoes and price hikes at the hands of politically opposed Arab nations. President Nixon promised that the United States would be independent of foreign energy sources within 10 years, and while that benchmark came and went, the idea has remained a political talking point ever since. It has been used as justification for environmentally disastrous practices like fracking and offshore drilling, and as a scare tactic to promote hawkish foreign policy agendas.
But it hasn’t been all bad! Just as the goal of self-reliance in our energy sector has been used to give grounds for destructive solutions, it has also been used to justify investments in more renewable, homegrown energy sources that not only wean us off of foreign power, but do so in an environmentally sustainable way. And unlike oil and natural gas, which are only feasible on a large scale, solar power can bring energy independence directly to the consumer in a more practical and immediate way. This “personal energy independence” addresses the same concerns about relying on foreign nations for our power, but on a personal scale.
The most obvious concern when relying on an outside source for power is security, and the extreme weather that much of the US faces keeps this concern front-of-mind. We are made aware of the fragility of our energy every time a strong storm knocks the power out, which can be quite often depending on your location and the age of your power grid. Power outages can quickly go from irritating to lethal, with sub-zero winters, and summers where the heat index regularly tops 100 degrees. Whether your system is tied in to the grid, or completely off-grid, your power can stay on no matter how many power lines are downed.
Energy independence also brings some stability to your budget. With regular variations in energy prices and usage, it can be difficult to predict your energy costs year-to-year, or even month-to-month. If you are running a completely off-grid system, it becomes incredibly easy to predict your power bill: It’s nothing! Aside from any outstanding costs from the purchase or installation of your system, which is just a regular monthly bill, there is no need to worry about fluctuating energy costs because you have none. Even with a grid tie-in system, you can rest assured that by producing most of your own energy, your power bill will stay below a predictable level that makes any fluctuations negligible. These fluctuations will typically be in your favor anyway. Depending on size and sunlight, grid tie-in systems often wind up producing more energy than they can use or store, meaning the power winds up getting sold to the power company.
One benefit of energy independence that can’t be so easily measured is the peace of mind it brings. Energy security and stability are not only beneficial for their own sake. Having fewer things to worry about, and thus less stress, improves mental and physical health in a myriad of ways. Not to mention the joy that comes from knowing that you are doing something every day to lessen your carbon footprint and make the world a better place!
Last January I had a 15 panel solar power system installed. This according to the solar company was supposed to supply enough power so I would have little power from the power company. NOT TRUE! All I have had was around a $25 power reduction per month. I can monitor daily power production on my computer. Any body know how many panels I would need to live on solar only? As of now I will never live long enough to break even.

asdf man, I'm a software developer myself so I appreciate the tenacity but most reputable websites in 2018 have sealed that particular security hole, and you would have better luck trying it on a login form rather than a comment box. As to the article I'm personally not convinced by the heating/cooling argument. A decently-designed passive house with a wood stove should take care of most of the issues of heating/cooling assuming you live in a reasonable climate. (There are some areas that are not very livable without AC, and will be completely uninhabitable in a few decades as climate change marches on, such as Phoenix AZ, but in that case I think the smartest thing to do is to move elsewhere.) I am tempted by the idea of a small solar panel to power small electric/electronic devices in the case of a grid outage but I think if you need it for heating/cooling or to meet other basic needs, you've made a mistake elsewhere in your homestead design. Solar panels don't last forever and it's pretty dubious whether the energy payoffs from a solar panel make up for the energy and carbon costs of their production.
