No one should turn down wind farming’s ultimate passive income for the next 30 or more years … even 60 years when there is a positive cash flow on the sum total of all base payments when computing inflation for the next 60 years based on the previous 60 years, as long as the next era’s energy resource is not perfected (at which time they would not renew the option for the second 30 years).
Turn your burning passions and daily musings into an entertaining audio show. Whether you want to talk about history, food, finance, or music, you can record and edit episodes from the comfort of your home. Once you have a large group of listeners, you can earn money from podcast sponsorships, affiliate marketing, selling products or eBooks, or crowdfunding. While you’ll have to produce episodes consistently, the time involvement is minimal and you can record several shows in advance.
One of the most well known ways of generating residual income is through ownership of stock in a publicly-traded company. Residual income streams can also include things like royalties from the sale of a book or song. Today, there are also several online platforms like Lending Club or Prosper that allow you to invest in personal or small business loans.

However, residual income typically has an expiration date, especially if it is being earned through a business. Effort must be continuously put into the business in order for someone to continue to receive residual income. Businesses must continue to market themselves in order to remain relevant. The best way to look at residual income in this sense is that it is a part-time job that earns full-time income.

If you're looking to get started in real estate, look at a crowd funding solution like RealtyMogul. It works similar to LendingClub - you commit as little as $5,000 towards a property. When the property is fully funded, you become an owner, and will receive your share of the earnings and appreciation in the property.  Check out RealtyMogul to learn more.
