Primary energy consumption of India is the third-largest after China and the US with 5.3% global share in the year 2015.[220] Coal and crude oil together account for 85% of the primary energy consumption of India. India's oil reserves meet 25% of the country's domestic oil demand.[209][221] As of April 2015, India's total proven crude oil reserves are 763.476 million metric tons, while gas reserves stood at 1,490 billion cubic metres (53 trillion cubic feet).[222] Oil and natural gas fields are located offshore at Bombay High, Krishna Godavari Basin and the Cauvery Delta, and onshore mainly in the states of Assam, Gujarat and Rajasthan. India is the fourth-largest consumer of oil and net oil imports were nearly ₹820,000 crore (US$110 billion) in 2014–15,[222] which had an adverse effect on the country's current account deficit. The petroleum industry in India mostly consists of public sector companies such as Oil and Natural Gas Corporation (ONGC), Hindustan Petroleum Corporation Limited (HPCL), Bharat Petroleum Corporation Limited (BPCL) and Indian Oil Corporation Limited (IOCL). There are some major private Indian companies in the oil sector such as Reliance Industries Limited (RIL) which operates the world's largest oil refining complex.[223]
There are a couple of problems with direct investment in real estate though. It’s expensive to buy even a single property, a minimum of tens of thousands of dollars, and there’s no way most investors can build a portfolio of different property types and in different regions to protect from those risks when you have all your money in just one or two investments.
Finally, I imagine the biggest debate with my ranking is Creating Your Own Product as the #1 passive income source. If most people have never created their own product, then it’s easy to give it a thumbs down. There won’t be much complaint about Private Equity Investing being in last place because most people are not accredited investors. But given I believe that plenty of people can create their own product if they try, pushback is inevitable because a lot of people simply don’t try!
I’ve had more jobs than I can count since I ‘officially started working’ at the age of 14. And I say officially because I was always hustling as a kid. There were the ordinary things like lemonade stands and selling my old junk at our family’s yard sales but I could get pretty creative when it came to making money. In high school, I remember asking my mom to give me extra bags of chips and snacks in my lunch so that I could re-sell them to my classmates for 75 cents or even a dollar. I was kind of a chubby kid so I guess my mom just figured I liked to snack a lot.
What I did: I first identified my favorite places in the world to live: San Francisco, Honolulu, Paris, Amsterdam, New York City, and Lake Tahoe. I then looked up the median rent and housing prices for each city. Then I factored in private education costs for two kids to be conservative given I may not have two kids and public schools are often good enough. After calculating all vital costs, I then did a self-assessment of how happy I was making $50,000, $100,000, $150,000, $200,000, $250,000, $350,000, $500,000, and $750,000. I decided working 20 hours a week making $200,000 a year is the best income balance for maximum happiness. 
To these human costs can be added the massive economic waste associated with the water and sanitation deficit.… The costs associated with health spending, productivity losses and labour diversions … are greatest in some of the poorest countries. Sub-Saharan Africa loses about 5% of GDP, or some $28.4 billion annually, a figure that exceeds total aid flows and debt relief to the region in 2003.Source 10

You can also participate in focus groups. Focus groups are hired to test products and give opinions before they reach the market. You would be a critical component of verifying they will have success and reach a high return on their investment. Surveys and focus groups are not ‘get rich quick’ schemes at all, but you can generate a few hundred a month.
Do you want to earn $100, $1000 — or even more — on the side? You can start earning extra income today with the help of this list of ideas I’ve put together. Spend an hour or two each day working on items that are practical for you, and you can build alternative income sources to help you improve your financial situation  While many of the items on this list are passive income ideas, not all of them are. Some items require you to actively work for success.
I have not. While I am intrigued with the possibility of making online income, it seems to be less passive then how I want to spend my time. Regarding your blog / site, you have done quite well for yourself. However, you have to keep pumping out content or your site would eventually go out of business. That sounds like more of a commitment then I would want. Regarding your book sales, it is probably relatively passive now, but certainly was not when you were writing the book. Now if you love it, great. Just not for me.
Build a list in a particular niche and tell them stories. Create a bond. Build a relationship with them. It's important. Then, when you've created a bit of culture, start marketing affiliate products or services to them that you think they might like. Just be sure that you personally vet out whatever it is that you're selling to avoid complaints if the product or service falls short.

Sam…just read this article and I want to say that this is the best posting on passive income I have ever read…in a blog, article, or book. Thanks for making a difference and being an inspiration as to how it can all be accomplished. One of the great benefits of the internet is that people are willing to share their stories and experiences with each other online. If we had this when I was working professionally (20-40 years ago), it would have saved me from making some rather poor financial decisions that affected my retirement income. In a way, the internet is making up for the loss of financial security in the loss of The Defined Benefit Plan for retirement. Bravo!

So one thing I have to disagree with after having done hours and hours of research from Multiple CPA’s is “Dividends – 21% (passive)”. Thats actually not right. Thats actually “active”. I actually paid 2 different CPA’s to do research on this topic. One of them I paid 500 dollars to actually dig out the IRS tax code and “prove” it. If you are active in a business and the business pays you dividends its still active income (not passive).

I think more and more people are recognizing the advantages of having multiple sources of income, thanks to the Great Recession. It was a real wake-up call to many good workers who lost jobs not because of poor performance but due to restructuring and cost-savings. They never considered themselves to be vulnerable and they were. We do have multiple streams of income and a fully-funded emergency fund, which has helped my family weather the ups and down life has brought us, including job loss.
In order to generate $10,000 in Net Operating Profit After Tax (NOPAT) through a rental property, you must own a $50,000 property with an unheard of 20% net rental yield, a $100,000 property with a rare 10% net rental yield, or a more realistic $200,000 property with a 5% net rental yield. When I say net rental yield, I’m talking about rental income minus all expenses, including a mortgage, operating expenses, insurance, and property taxes.
Some good writing here! I am a realtor myself and frequently get in touch with clients that consider buying a realty estate a conservative of investing. I once heard of a transport company in Vienna, Austria, which focused their entire profit on buying eventually every house available in the downtown for about 80 years. That must be some of a passive income!

I have been using,”multiple streams of income,” as my mantra during this rough patch. Being an interior designer easily translates into designing other things as well. I have been designing jewelry that is customized in price and style for different stores. I also opened an Etsy shop for my jewelry and for vintage items that I find in my treasure hunting for clients.I am bringing in an extra $1500-$3000 a month, and I am having fun! My first passion is always going to be interior design, and I am thankful for the clients I have!
Real Estate Income – Since we moved up to Newport Beach, I started renting out my condo in San Diego. My monthly cash on cash return is $300(I charge $1,900 for rent and my total payments including mortgage, HOA, property tax and insurance are $1,600) but I also get back around $350 every month in principal and about a $150 tax savings per month. But even this income is inconsistent, since sometimes expenses will pop up like last month when I had to buy a new A/C for $3,000!

One great way to generate a passive income is through affiliate marketing. Now, this does depend on the size of your list. Yes, size matters when it comes to your list. Especially if you're looking to make some serious money and do it on autopilot. But, list-building takes time. It doesn't happen overnight. And you need to add value to your list or you become obsolete.
Developing passive income is different. With the exception of one of my passive income streams (cryptocurrency mining), all of the others require real, hard work. Truly, I understand the barriers for people getting into building alternative income streams. I would say that most people WANT passive income, but truly aren’t willing to put in the blood, sweat, and tears to make it happen.

* I use Personal Capital to track all my finances in one place. It’s much easier to use their free software to follow 28 accounts on one platform than to log into various accounts to check my balances. They’ve also got great tools for x-raying your portfolio for excessive fees, recommending a more optimized asset allocation, and planning for retirement with their Retirement Planner.

With $200,000 a year in passive income, I would have enough income to provide for a family of up to four in San Francisco, given we bought a modest home in 2014. Now that we have a son, I'm happy to say that $200,000 indeed does seem like enough, especially if we can win the public-school lottery to avoid paying $20,000 to $50,000 a year in private-school tuition.
This figure is based on purchasing power parity (PPP), which basically suggests that prices of goods in countries tend to equate under floating exchange rates and therefore people would be able to purchase the same quantity of goods in any country for a given sum of money. That is, the notion that a dollar should buy the same amount in all countries. Hence if a poor person in a poor country living on a dollar a day moved to the U.S. with no changes to their income, they would still be living on a dollar a day.
Lots of good insights here. I’ve just recently gotten my own website for making online income. Also gotten a website for my fledgling voice over business. There’s a lot to learn when it comes to making passive income online, especially if you’re not financially savy, this is a very helpful blog in that regard, with all the useful tools and reference materials, it certainly removes a lot of guesswork.

In focusing on your wealth management goals, investment income is obviously critical but you might fund your goals from wider sources of income.  A typical long-term portfolio might produce about half its return as income and the other half as capital growth, though in times of duress the capital growth component wanes.  In this low-interest rate climate, some sources of income have become quite expensive and may prove disappointing against your spending needs.  But by tax efficiently and sustainably drawing income from wider sources, you might meet your goals while more prudently balancing risk against reward.
