Hey Suhani, there are many benefits. The obvious is once you are producing at least some of your own power, your electric bill is smaller. Also your power is coming from a green source, so when you make a pot of coffee, you are not adding CO2 to the air, mercury to the rivers and lakes, and coal ash to the ground water. We installed solar and wind technology at our home 16 years ago, and today it produces abouty 90% of our power. Our system is set up to run independent of the utility if need be, but normally it does synchronize with it and feed power both ways. This allows us to have a much smaller battery bank, but still one that can run our house overnight if need be.
Here's the tricky part. Many people grow tomatoes in their garden even though really it's cheaper, and much easier to buy them at the store. Some claim they taste better, or are better for you. That may be true, but for the time, effort and resources employed, for most people, tomatoes are a very thin slice of their overall diet, the benefit isn't even noticable alongside all the hamburgers, pizzas, and boxes of cereal they consume as well. Truth be known, maintaining a garden for many is therapeutic, and you can't put a price on that. We just grow electrons in ours. Besides the environmental benefits, there is also the fact that our home has not been without power for even a minute the last 16 years now, hard to put a price on that. On average our power goes out maybe twice a year here, anywhere from a few hours to a few days. Most times we are not even aware of it. I enjoy operating and even maintaining the equipment, much like some people like to work on cars, or make their own furniture, again, the therapy portion of the deal. It's a nice sense of accomplishment, growing your own vegetables, or electrons, one you can't get no matter where you might buy those things elsewhere, no matter how cheaply you can find them. You just have to decide what you want out of life, and then head that way, these decisions will follow. I'd try getting involved in some of the sources below and see if it still interests you in a few months. Home Power Magazine is a great first starting place, they have "energy fairs" in the calendar section in the back, if you can get to one of them, you'll be meeting hundreds of people who have done these things first hand, you'll know if they are the kind of people you like right off, and if the lifestyle is worthwhile to you.
Lots of people talk about the financial benefit of solar and wind power. To be honest, it is very fleeting. We spent around $8000 on all our equipment 16 years ago, it is likely cheaper today. Now our $60 electric bill is $5 each month. We could have put the same $8000 in long term bonds, and just paid the electric bill out of the interest, but what fun would that be, and what good would it do me in a power failure. Don't rely on other peoples conclusions on this, ask the questions, reserve the final conclusions for yourself, everyone is different. Take care, Rudydoo
