Indoor air pollution resulting from the use of solid fuels [by poorer segments of society] is a major killer. It claims the lives of 1.5 million people each year, more than half of them below the age of five: that is 4000 deaths a day. To put this number in context, it exceeds total deaths from malaria and rivals the number of deaths from tuberculosis.Source 15
As the third-largest economy in the world in PPP terms, India has attracted foreign direct investment (FDI).[301] During the year 2011, FDI inflow into India stood at $36.5 billion, 51.1% higher than the 2010 figure of $24.15 billion. India has strengths in telecommunication, information technology and other significant areas such as auto components, chemicals, apparels, pharmaceuticals, and jewellery. Despite a surge in foreign investments, rigid FDI policies[302] were a significant hindrance. Over time, India has adopted a number of FDI reforms.[301] India has a large pool of skilled managerial and technical expertise. The size of the middle-class population stands at 300 million and represents a growing consumer market.[303]
If you have a blog or other type of site, you can build affiliate links to different services on the website. Many people use Amazon as an affiliate partner. For example, if you are a beauty blogger writing about different products, you can set up Amazon affiliate links on your blog so that whenever someone buys the product you mention on Amazon, you receive a percentage of the sale. Amazon is not the only affiliate partner out there. Here is good, in-depth information on affiliate marketing. 
“Start-up time” required: Poor – Experienced niche site builders will be well versed with outsourcing certain tasks and running through the whole process very efficiently, but when you first start out, it can take a long time to earn your first dollar from a niche site.  Doing research, designing the site, writing content, and doing proper SEO work can all be very time consuming, and the payoff isn’t always something you can rely on.
ie first you need to haul ass and do something crazy, eg write a quality 20,000 word ebook (insanely not passive hahahah), but then you get to sit back and enjoy seeing PayPal sale messages pop up on your iPhone each morning as sale after sale after sale is made…on an ongoing basis and without any additional work. That’s some seriously Pina Colada flavored passive goodness!
Writing and publishing an eBook has become a widely popular means of earning passive income in recent years. eBooks on non-fiction topics like online marketing, business development, career advice, and the like are especially successful. While fiction eBooks are also good sellers, the market for them is much more competitive as compared to non-fiction ones. Once you've written an eBook, you can put it up for sale on platforms like Amazon's Kindle Direct Publishing or Apple's iTunes Connect.
I am still working on my passive income, however I like multiple income streams even more. My favorite is capital gains because it is one of the lowest rates. One of the best passive income streams is a pension/Social Security. As I near retirement, I like the concept of it supporting my needs and my 401k supporting my wants. In addition, my brokerage accounts are all at capital gains rates. Don’t misunderstand, I am still working on adding more because I like multiple income streams!
I just can’t seem to get my head around creating my own online product. When you talk about it, you make it sound like its mostly just about putting in the time and plugging away at it. Problem is I can never seem to come up with any ideas for a site or product that seem remotely unique or compelling or that I have any special knowledge about. The stuff I do know about is pretty commodity type knowledge that can mostly be found on thousands of sites on the internet already. Any tips on discovering what your “unique angle” is? I mean, you have a pretty compelling and somewhat unique personal story of working on wall street and then walking away at a young age.
The telecommunication sector generated ₹2.20 lakh crore (US$31 billion) in revenue in 2014–15, accounting for 1.94% of total GDP.[263] India is the second-largest market in the world by number of telephone users (both fixed and mobile phones) with 1.053 billion subscribers as of 31 August 2016. It has one of the lowest call-tariffs in the world, due to fierce competition among telecom operators. India has the world's third-largest Internet user-base. As of 31 March 2016, there were 342.65 million Internet subscribers in the country.[264]
However, you should pick a niche and blog about that. If you're launching a money related blog, maybe it'll be about how to make money in real estate or simply how to make money online. Pick the niche and stick to it. If it's a diet and fitness related blog, maybe the niche is the Ketogenic diet, the Atkins diet or some other form of diet or fitness.
The bottom line is, it’s smart to have multiple income streams no matter who you are. Why? Because the more ways you can earn money without compromising your integrity, the better off you’ll be. And if you’re self-employed, having multiple income streams is almost essential. Not only will you enjoy a higher income, but you won’t go broke if one stream ends out of the blue.
If you're a graphic designer or even an amateur artist, there are plenty of sites which will pay you for sharing your artwork. Sites like Etsy, Zazzle, and The Souled Store allow people to add their designs to T-shirts, phone cases, mugs, posters, book covers, and more. If and when these products are bought, the sites then pay a commission to the contributing artist.
Industry accounts for 26% of GDP and employs 22% of the total workforce.[165] According to the World Bank, India's industrial manufacturing GDP output in 2015 was 6th largest in the world on current US dollar basis ($559 billion),[166] and 9th largest on inflation-adjusted constant 2005 US dollar basis ($197.1 billion).[167] The industrial sector underwent significant changes due to the 1991 economic reforms, which removed import restrictions, brought in foreign competition, led to the privatisation of certain government-owned public-sector industries, liberalised the foreign direct investment (FDI) regime,[168] improved infrastructure and led to an expansion in the production of fast-moving consumer goods.[169] Post-liberalisation, the Indian private sector was faced with increasing domestic and foreign competition, including the threat of cheaper Chinese imports. It has since handled the change by squeezing costs, revamping management, and relying on cheap labour and new technology. However, this has also reduced employment generation, even among smaller manufacturers who previously relied on labour-intensive processes.[170]
The term Multiple Streams of Income in a way voices and explains itself. It’s the theory of earning more than one type of income from more than one source. Generating multiple sources of income is a key to wealth creation, it becomes even more special when you’re doing it with a passive income which does not really require a lot of time and efforts from you (We’ll talk more about that later).
For a person working for a wage, their source of income is their job, or their labor (aka their time that they sell to someone). But you can own a house, and rent it out, and when your renters pay you renter every month, the source of that income check is your rental property, or your house. It would just be called rental income. If you have money in the bank in an account that pays interest, those interest payments are another source of income. We can say the source is interest payments, or we can identify the asset that is generating rent, and say your money in the bank that is generating “rent” (aka interest) is your source of income.
