Certain alternative energy sources do not fall under the traditional definition of commodities, as many of these alternative sources of power (such as wind) are not physical resources that can be extracted and sold. But this category of natural resources is closely related to commodity markets, as the development of alternative energy sources has a significant impact on prices for a wide variety of materials and resources
Interest in establishing exposure to alternative energy industries has surged in recent years, as investors have sought to identify which corners of the global energy market will see market share expand in coming years. These investments, while promising over the long term, have a tendency to exhibit significant volatility in the short-term.
Though physical exposure to many alternative energy sources isn\'t possible, there are a number of options for investing in alternative energy, including ETFs and ETNs.
