"Obama's 'New Energy for America' plan will aim to put 1 million plug-in hybrid cars on the roads by 2015, reduce greenhouse gas emissions by 80% by 2050 and ensure 25% of our electricity comes from renewable sources by 2025.
"Obviously, to enact such a bold plan would take a massive investment and mean billions for companies involved in the still-fledging alternative energy field.
"And while investors can certainly pick and choose between individual companies with exposure to the sector, several ETFs have popped up that offer broad exposure to the industry. In particular, I like Market Vectors Global Alternative Energy.
"With this ETF, shareholders have a healthy stake in hydroelectric power generator, solar cells, as well as some exposure to gasoline alternatives such as ethanol and fuel cells.
"GEX shies away from micro-cap companies with unproven business models and loads up on larger, more-established players -- more than half of its assets are invested in companies with market caps of $6 billion or greater.
"The fund is also more geographically diversified than many competitive offerings, with roughly 70% of the portfolio invested overseas.
"That foreign exposure will likely give GEX an edge, considering the United States is still behind the alternative energy curve in some respects compared to many countries throughout Europe and Asia.
"With Obama touting the need for alternative energies in our economy, investing in the sector is one of the closest 'sure things' in the investment world should he be elected.
"But rather than trying to decipher which company is best suited to outperform, investing in a fund like GEX allows you to simply profit from the entire sector.
