Buying RECs isn’t the same as buying renewable energy directly, because once power enters the grid, it is nearly impossible to tell where it came from. Instead, when consumers buy RECs, they are buying a certificate of energy ownership, so they can effectively claim a portion of green energy on the grid. For many people and organizations, purchasing RECs is an accessible way to support renewable energy infrastructures, especially if they are not in a position to invest in solar panels or other renewable energy technology for their homes or businesses.

Solar energy is the most popular and well-known renewable technology for homes and businesses, though wind energy is also available for small-scale installs. The costs to purchase and install a standard solar array can run upward of $18,000, while wind turbines fall closer to $30,000.

The peak demand for fossil fuels is soon approaching. Although the affordable prices for coal and gas are expected to continue for the immediate future, there is a very real shift occurring in the global energy market. Fossil fuels currently power nearly of electricity in the United States, but Bloomberg’s New Energy Outlook 2017 speculates that due to the demand for cleaner and greener energy, and the increasing affordability of renewable technologies, by 2040, 38% of electricity in the U.S. will be sourced from renewables like solar, wind, and ocean energy.

Here are some fast facts about the current—and future—state of fossil fuels vs. renewables in the U.S. energy sector.

Fossil Fuels Remain King—For Now Renewables are getting less expensive, with the average price of solar panels falling over 60% since 2010 and wind turbine prices falling 20-40% since 2008; electricity from coal and natural gas is still directly cheaper, though only until 2020, according to a 2018 analysis by the International Renewable Energy Agency. To note, the current and projected price of fossil fuels doesn’t truly reflect the social and environmental costs of extraction and use, so though the price may seem low, the true cost to society can be much higher.
