Warren Buffett is a big fan of Chevron (CVX 0.65%). His company, Berkshire Hathaway, owns 118.6 million shares of the oil giant, or about 6.8% of its outstanding stock. Those shares are currently worth $17.1 billion. That makes Chevron Berkshire's fifth largest holding, at 6.1% of its investment portfolio.

A big draw of Chevron is its high-yielding dividend. It supplies Berkshire with over $800 million in dividend income each year. However, Chevron isn't the only high-yielding dividend stock in the energy sector. Enbridge (ENB -0.36%), Brookfield Renewable (BEPC 0.50%) (BEP 0.42%), and Enterprise Products Partners (EPD 0.16%) stand out to a few Fool.com contributors as even better energy stocks to buy for a high-yielding income stream.

Buffett's portfolio contains both public companies and a huge and varied collection of fully owned businesses. Energy is a big theme across both, with particular emphasis on utilities and midstream assets in Berkshire Hathaway's portfolio of owned businesses. Canada's Enbridge can give you exposure to both in one high-yield energy investment, given its lofty 5.9% yield.

The core of Enbridge's business is its midstream portfolio -- largely oil and natural gas pipeline and transportation assets -- which makes up around 75% of earnings before interest, taxes, depreciation, and amortization (EBITDA). The rest of the business is split between natural gas utilities and clean energy assets. What's notable here is that shifting along with the world's energy needs is a core business approach, so the current split will probably continue to shift in a "clean" direction. That means you can own Enbridge for decades to come and not have to worry that it will be left behind as energy sources such as solar and wind power grow.
