According to GlobalData, non-hydro renewable energy will be the fastest growing power source in the U.S. through 2025. Installed capacity is expected to increase from 121.9 gigawatts (GW) in 2015 to 216 GW in 2025. “US Power Market Outlook to 2025, Update 2015 – Market Trends, Regulations, and Competitive Landscape,” finds the strong rate of growth suggests that the current U.S. government fully supports the growth of clean generation technologies. The U.S. was one of signers of the most historic climate treaty agreed upon in Paris earlier this month during COP21.

Chiradeep Chatterjee, GlobalData’s senior analyst covering Power, warns that this positive forecast for non-hydro renewables could be subject to the result of the 2016 US presidential election, with a Republican victory likely to mean considerable changes to present policies due to the party’s lower support for green energy projects in general.

“There are several renewable power regulations that have been implemented or revised by the Obama administration in 2015 that will aid the production of renewable energy,” explained Chatterjee. “For example, the Fannie May Green Initiative provides smart energy through financing solutions, while the Weatherization Assistance Program, instituted by the Department of Energy, offers grants to improve the energy efficiency of resident low-income families. Such initiatives are positive steps to achieving green targets established by US states.”

Targets take the form of Renewable Portfolio Standards programs, state policies that mandate a certain percentage of energy supplied to consumers by a utility within the state should come from renewable sources.

“Generally, the objectives are ambitious, ranging from 10% to 40%, with a variety of target dates. However, there is considerable variation between individual states, as Hawaii is aiming for renewables to constitute 100% of all energy use by 2045, while South Carolina is targeting just 2 percent by 2021.” Chatterjee concluded, “Attitudes towards the growth of green energy differ throughout the US, and it must be acknowledged that other sources of power will remain dominant throughout the forecast period.”
