Investors looking for a generous yield will likely be attracted to Enterprise Product Partners' (NYSE: EPD) fat 7.8% yield. Notably, over the past decade the average annual hike has exceeded the historical rate of inflation growth, which means the buying power of the distribution has grown over time. That said, the partnership is a vital link in the energy industry, and so long as the world still needs oil, natural gas, and the products into which they are made, demand for Enterprise's assets and services should hold up.
