Advantages and disadvantages of renewable energy

Reading Time: 6 minutes

Wind, geothermal, solar, hydro, and other renewable technologies are a widely popular source of energy throughout the world today. Countries, corporations, and individuals are adopting renewables for a number of great benefits. In this article, we’ll dive into some of the advantages and disadvantages of renewable energy.

Types of renewable energy sources

  • Wind power: leverages the power of wind motion to generate electricity, created by the uneven heating of Earth’s surface. 
  • Solar power: uses energy from the sun to generate electricity and heat 
  • Hydropower: utilizes fast-moving water to spin turbines and generate electricity 
  • Biomass: generates electricity from organic plant matter .
  • Geothermal: leverages heat from inside the earth to generate electricity 

Advantages of renewable energy

Renewable energy has multiple advantages over fossil fuels. Here are some of the top benefits of going green:

  • Renewable energy won’t run out
  • Renewable energy has lower maintenance requirements
  • Renewables save money
  • Renewable energy has numerous environmental benefits
  • Renewables lower reliance on foreign energy sources
  • Renewable energy leads to cleaner water and air
  • Renewable energy creates jobs
  • Renewable energy can cut down on waste

1. Renewable energy won’t run out

Renewable energy technologies use resources straight from the environment to generate power. These energy sources include sunshine, wind, tides, and biomass, to name some of the more popular options. Renewable resources won’t run out, which cannot be said for many types of fossil fuels – as we use fossil fuel resources, they will be increasingly difficult to obtain, likely driving up both the cost and environmental impact of extraction.

2. Maintenance requirements are lower for renewable energy

In most cases, renewable energy technologies require less overall maintenance than generators that use traditional fuel sources. This is because generating technology like solar panels and wind turbines either have few or no moving parts and don’t rely on flammable, combustible fuel sources to operate. Fewer maintenance requirements translate to more time and money saved.

3. Renewables save money

Using renewable energy can help you save money long term. Not only will you save on maintenance costs, but on operating costs as well. When you’re using a technology that generates power from the sun, wind, steam, or natural processes, you don’t have to pay to refuel. The amount of money you will save using renewable energy can vary depending on a number of factors, including the technology itself. In most cases, transitioning to renewable energy means anywhere from hundreds to thousands of dollars in savings—find out how much you can save by switching to solar energy.

4. Renewable energy has numerous environmental benefits

Renewable energy generation sources emit little to no greenhouse gases or pollutants into the air. This means a smaller carbon footprint and an overall positive impact on the natural environment. During the combustion process, fossil fuels emit high amounts of greenhouse gases, which have been proven to exacerbate the rise of global temperatures and frequency of extreme weather events.

The use of fossil fuels not only emits greenhouse gases but other harmful pollutants as well that lead to respiratory and cardiac health issues. With renewable energy, you’re helping decrease the prevalence of these pollutants and contributing to an overall healthier atmosphere.

5. Renewables lower reliance on foreign energy sources

With renewable energy technologies, you can produce energy locally. The more renewable energy you’re using for your power needs, the less you’ll rely on imported energy, and the more you’ll contribute to U.S. energy independence as a whole. Renewable energy sources can help us minimize the geo-political risks associated with fossil fuels, from trade disputes to political instability to pricing wars, all of which are often rooted in access to oil.

6. Renewable energy leads to cleaner water and air

When you burn fossil fuels to generate electricity, it contaminates the air and water we use. For example, coal power stations release high volumes of carbon dioxide and nitrous oxide, as well as harmful toxins like mercury, lead, and sulfur dioxide. Health problems from ingesting these elements can be dangerous, and even fatal in some cases. Investing in renewable energy is a great way to work against these risks, as renewables have a far lower negative impact on our air and water. 

The use of fossil fuels not only emits greenhouse gases but other harmful pollutants as well that lead to respiratory and cardiac health issues. With renewable energy, you’re helping decrease the prevalence of these pollutants and contributing to an overall healthier environment.

7. Renewable energy creates new jobs 

While the U.S. shifts its focus to combat global warming, we’re setting ambitious carbon-reduction goals that require labor to get the job done. Today, the renewable energy sector employs three times as many people as fossil fuels do in the U.S. That number is expected to rise over the next few years—and as a plus, these jobs tend to pay above average wages, making it a very attractive career option and an overall economic boom. 

8. Renewable energy can help solve our waste problem

Specifically, biomass energy can offer a big benefit in this way. Biomass generators consume used organic products like vegetable oil, corn and soybean byproducts, and even algae to generate energy. Because of this, using biomass as an energy source can reduce the amount of waste that goes into landfills, which helps cut down on carbon emissions and environmental contamination. 

Disadvantages of renewable energy

Renewable energy has many benefits, but it’s not always sunny when it comes to renewable energy. Here are some disadvantages to using renewables over traditional fuel sources:

  • High upfront costs
  • Intermittency
  • Storage capabilities
  • Geographic limitations
  • Renewables aren’t always 100% carbon-free

1. Higher upfront cost

While you can save money by using renewable energy, the technologies are typically more expensive upfront than traditional energy generators. To combat this, there are often financial incentives, such as tax credits and rebates, available to help alleviate your initial costs of renewable technology.

2. Intermittency

Though renewable energy resources are available around the world, many of these resources aren’t available 24/7, year-round. Some days may be windier than others, the sun doesn’t shine at night, and droughts may occur for periods of time. There can be unpredictable weather events that disrupt these technologies. Fossil fuels are not intermittent and can be turned on or off at any given time. Wondering if you should make the switch to renewables?

3. Storage capabilities

Because of the intermittency of some renewable energy sources, there’s a high need for energy storage. While there are storage technologies available today, they can be expensive, especially for large-scale renewable energy plants. It’s worth noting that energy storage capacity is growing as the technology progresses, and batteries are becoming more affordable as time goes on.

4. Geographic limitations

The United States has a diverse geography with varying climates, topographies, vegetation, and more. This creates a beautiful melting pot of landscapes but also means that there are some geographies that are more suitable for renewable technologies than others. For example, a large farm with open space may be a great place for a residential wind turbine or a solar energy system, while a townhome in a city covered in shade from taller buildings wouldn’t be able to reap the benefits of either technology on their property. If your property isn’t suitable for a personal renewable energy technology, there are other options. If you’re interested in solar but don’t have a sunny property, you can often still benefit from renewable energy by purchasing green power or enrolling in a community solar option.

5. Not 100% carbon-free

Although solar panels and other forms of renewable energy drastically reduce carbon emissions, these resources aren’t always completely clean. The manufacturing, transportation, and installation of renewable energy, like wind turbines, can create a carbon footprint since they’re usually produced in factories that are powered by fossil fuels —not to mention the diesel and gasoline needed to fuel the transport trucks. As the U.S. becomes more and more electrified – from solar panels on factories, to electric transport trucks – carbon emissions associated with solar will continue to decrease.

6. Supply chain constraints

Renewables must have an effective distribution network created to transfer the energy where it’s needed on a large scale. These networks need non-renewable energies to be generated, which offsets the benefits of renewable energy for a bit until it’s paid back. Additionally, politics can play a factor in installing renewable energy if it’s not a priority among local governments. 

Renewable energy has more benefits than drawbacks

When it comes to renewable energy, the positives outweigh the negatives. Transitioning to renewables on a personal, corporate, or governmental level will not only help you save money but also promote a cleaner, healthier environment for the future.

Installing solar panels is one of the easiest ways to go green. By signing up on the EnergySage Solar Marketplace, you can compare multiple quotes from local, pre-screened installers to see what solar costs and savings for your property. The quotes will also include estimates of the amount of carbon dioxide emissions you will offset over 20 years, and what this equates to in both trees planted and gallons of gasoline burned.
