Frequently asked questions about renewable energy sources

Since you’re here, you might be interested in learning more about renewable energy and the US energy market trends. Below, you will find answers to some of the popular questions linked to renewables.

What is renewable energy?

Renewable energy comes from natural and self-replenishing sources (sources that don’t run out). Renewable power generation is typically characterized by having a zero- to low-carbon footprint, which is why such energy solutions are sometimes referred to as “clean energy.” Examples of renewables include wind power, solar power, hydropower, and biomass.

In 2022, renewable sources in the US were responsible for over 20% of all electricity generation, including 10.3% of energy generated by wind turbines, 6.0% by hydropower plants, 3.4% by solar panels, 1.2% from biomass, and 0.4% by geothermal power plants.

What are the top examples of renewable energy sources?

Wind energy is generated by wind turbines that convert kinetic energy to electricity. They can be placed on water (offshore wind farms) or on land (onshore wind farms). Wind energy constitutes the biggest share of renewable energy production in America.

Hydropower generation leverages the movement of flowing or falling water. Hydroelectric power operations can be placed at river dams or utilize tidal power in oceans.

Solar power utilizes solar photovoltaic modules to convert sunlight into electricity. Solar installations can be found throughout the world in various forms, from solar panels on roofs to solar power projects covering large, non-urban areas, such as fields or lakes.

Bioenergy is a name for green energy generated by burning organic matter. This matter, known as biomass, is considered a renewable source because it can be regrown. Burning biomass emits carbon, but plants that will become biomass absorb similar quantities of carbon when growing.

Is natural gas renewable?

Often misunderstood as renewable, natural gas is not naturally replenishable. Only a limited amount of natural gas exists, and it can be depleted, similarly to other fossil fuels like coal or oil. However, natural gas is also one of the cheapest energy sources, and burning it produces less nitrogen oxides and other harmful elements than oil products.

While natural gas services are not renewable energy or “green energy,” this power generation method is less harmful to the environment than other fossil fuels.

What is the current shape of the renewable energy industry in the USA?

The United States has enough renewable energy sources to produce more than 100 times the amount of electricity that American citizens use. For years now, the country has been taking steps to increase its volume of renewable energy generation. 2022 was the first year in history when more energy was generated from renewable sources than from coal.

Recognizing the need for renewable electricity, the US government offers funding opportunities for renewable energy research for a variety of projects linked to the development of renewables across the nation. According to the website of the Office of Energy Efficiency & Renewable Energy, domestic solar energy generation in the USA is expected to grow by 75%, and wind power generation by 11% by 2025. The US Energy Information Administration (EIA) projects that renewables will generate 44% of US electricity by 2050.

What trends are shaping the renewable energy sector?

The United States is undergoing an important shift towards more sustainable energy solutions. Challenges linked to climate change are increasingly recognized by the public, carbon emissions are frowned upon, and societal demands to give up fossil fuels in favor of renewable energy solutions are projected to grow further and further.

With a growing number of new infrastructure investments planned in renewable power generating facilities, the sustainable energy transition will accelerate even further in the coming years. 

Meanwhile, companies in the renewable energy market aim to enable a sustainable future for the planet while meeting the energy needs of industry clients and private consumers of today. As a result, they are constantly developing ways to increase the energy efficiency of various renewable power assets and their energy storage capabilities.

The future belongs to renewable energy companies

While the largest renewable energy companies steadily grow in value, middle market companies can still disrupt the evolving renewables market by leveraging government incentives and attracting strategic investors with innovative approaches to renewable technology.

With public support, government backing, and continuous financing from private investors, it is safe to say that the entire green energy sector has a fantastic future ahead of it. American renewable energy companies are real contenders for achieving lasting success on a global scale.
