Alternative ETFs: Investing In the Shift From Oil

Demand for crude oil is increasing as countries develop and the world population increases, and the world may soon run out of oil before a viable alternative is readily available. Therein lies the case for alternative energy exchange traded funds (ETFs).
According to the University of California Davis, global crude oil reserves will run dry 90 years before a replacement is available at our current technological progression, reports Anil Das For International Business Times. That means if we’re going to be ready, world governments will have to step up their efforts at making alternative energy a larger source of power production.
Previous projections put 2040 as the time when alternatives can viably replace oil, but researchers also believe that the estimate could be “overly optimistic about the diffusion of new technologies.”
