Wind energy ETFs like the First Trust Global Wind Energy ETF (FAN) and the Global X Wind Energy ETF (WNDY) offer diversified exposure to public wind energy companies. The US does not currently have a dedicated wind energy ETF.

The US Wind Capacity outlook for 2021-2030 estimates over 170 GW of wind capacity will come online, representing over $270 billion in investment [1]. Wind energy represents a major investment opportunity as renewable energy expands.


Hydropower is the use of flowing water to generate electricity. Hydropower projects often require the construction of dams, powerhouses and other infrastructure to harness the energy from rivers or waterfalls. There are various ways to invest in hydropower generation.

One approach is to invest directly in hydropower projects. This involves providing financing for the development and construction of new hydropower plants. Major hydropower generation companies like Duke Energy, Statkraft and Eletrobras undertake large-scale hydropower projects and seek investors to help fund the high upfront capital costs.

Another option is to invest in companies that own and operate hydropower assets. Many utilities and independent power producers have hydropower plants in their generation portfolios. Investing in their stocks or bonds provides exposure to existing hydropower facilities and their cash flows. Examples include American Electric Power, Brookfield Renewable Partners and Algonquin Power & Utilities.

There are also exchange-traded funds (ETFs) focused on the hydropower industry, such as the Global X Hydrogen ETF and the Invesco WilderHill Clean Energy ETF. These funds hold a basket of stocks related to hydropower and other renewable energy sources.

Overall, hydropower investments allow investors to support clean electricity generation while potentially earning attractive returns from stable, long-life assets.


Bioenergy refers to renewable energy derived from biological sources, such as plants and organic waste materials. There are two main ways to produce energy from biomass: biofuel production and biopower.

Biofuels like ethanol and biodiesel are made by processing biomass feedstocks like corn, sugarcane, and vegetable oils. These liquid biofuels can replace gasoline and diesel for transportation. Major biofuel producers include companies like POET and Valero Renewables. Investing in biofuel companies provides exposure to the growing renewable transportation fuel market.

Biopower is generated by burning biomass directly to produce steam and electricity. Sources of biomass for power production include forest residues, agricultural crops and waste, and municipal solid waste. Biopower accounts for almost half of renewable energy produced in the United States. Key players in biopower include companies like Drax and Enviva that develop utility-scale biomass power plants.

The bioenergy industry is expected to see strong growth as governments continue to enact policies that encourage renewable power generation and low carbon transportation fuels. With rising demand, bioenergy companies and stocks can offer attractive investment opportunities.

Geothermal Energy

Geothermal energy utilizes heat from beneath the earth’s surface to generate electricity and provide heating and cooling. There are three main types of geothermal energy projects: geothermal power plants, direct use, and geothermal heat pumps (GHPs).

At geothermal power plants, wells are drilled into underground reservoirs to tap into hot water or steam that spins a turbine to generate electricity. The United States leads the world in geothermal electricity generation capacity, with over 3.7 gigawatts as of 2019, according to the U.S. Energy Information Administration. Major geothermal resources are located in western states like California, Nevada, Utah, Idaho, and Oregon.

Direct use applications take advantage of geothermal reservoirs closer to the earth’s surface that provide water for bathing, agriculture, aquaculture, and district heating. Direct use of geothermal energy dates back thousands of years, with examples found around the world from Turkey’s hot springs to Polynesian spas.

Geothermal heat pumps use shallow ground or water temperatures for space heating and cooling. These systems transfer heat between the earth and buildings, and are one of the most efficient heating and cooling technologies available.

Publicly traded geothermal companies involved in geothermal project development and technology include Ormat Technologies, Geothermal Engineering Ltd., and GreenFire Energy Inc. Investment in geothermal supports sustainable baseload power generation, reduces greenhouse gas emissions, and provides energy security.

Ocean Power

Ocean power refers to technologies that harness the energy of the oceans to generate electricity. There are several types of ocean power technologies that show promise for large-scale energy production:

Tidal Power

Tidal power utilizes the rise and fall of ocean tides to generate electricity through tidal barrage systems or in-stream tidal turbines. Tidal barrages construct dams across inlets that fill with water during high tides and empty during low tides. The movement of water turns turbines to produce electricity. In-stream tidal turbines function similar to wind turbines, where flowing tidal currents turn underwater rotors to generate power. The world’s first major tidal power plant opened in La Rance, France in 1966 and has an installed capacity of 240 MW. Modern tidal projects are being tested and implemented around the world, including in the Bay of Fundy, UK, South Korea, and Australia.

Wave Power

Wave power devices harness the kinetic energy of ocean surface waves to generate electricity. These devices utilize different design concepts, such as oscillating water columns, hinged contour devices, or buoys, to capture wave motion that powers turbines. While no wave power plants are currently operating at commercial scales, prototypes and pilot projects have demonstrated success off the coasts of Portugal, Australia, and Oregon.

Ocean Thermal Energy

Ocean thermal energy conversion (OTEC) utilizes the temperature difference between warm surface seawater and cold deep seawater to generate power. The temperature gradient drives a heat engine, which produces electricity. An OTEC plant was built in Hawaii in 2015, but technical challenges have limited widespread adoption of this technology.

Salinity Gradient

Salinity gradient energy utilizes the difference in salt concentration between fresh and salty water. As the two water types mix, energy is released that can be captured to generate electricity. While still an emerging and experimental technology, salinity gradient has potential for power generation in places where freshwater rivers meet the sea.

Investment opportunities in ocean power include startups focused on innovative technologies, tidal and wave power project developers, and companies that manufacture ocean power infrastructure like turbines. Governments are also investing heavily in ocean power R&D. According to a report, annual investment in ocean energy increased fivefold from $216 million in 2011 to $1.1 billion in 2015.
