Renewable energy is growing as an alternative to finite energy sources such as coal, oil, and natural gas. Renewables are resources that can be replenished (e.g., solar, wind, hydropower) and generate lower operating emissions than non-renewable energy sources. However, they also have drawbacks, including variable power output, higher upfront costs, and the need for storage.
In this guide, you will learn about the pros and cons of renewable and non-renewable energy sources. We will also assess them in terms of reliability, environmental impact, cost, and how storage technology will enhance the flexibility of these energy sources. We will also look at some solutions, such as the EcoFlow DELTA 3 Plus and DELTA Pro 3.
What Is Renewable Energy?
Renewable energy is generated by natural resources that renew themselves over time. This allows for continued use of these resources with less depletion of the original resource compared to traditional fuels.
Examples of renewable energy include:
Solar energy created by sunlight
Wind energy created by moving wind (air)
Hydroelectric power generated by flowing water
Earth-based geothermal energy created by Earth's temperature
Biomass produced from biological matter
Energy generated through tidal and wave motion within bodies of water.
Although renewable energy production has environmental impacts, these impacts differ based on the technologies used, the locations where production occurs, how products are manufactured, and the size of the project. Even though some renewable energy systems produce lower emissions during operation, they may have adverse effects on land, habitats, water systems, or ecosystems.
What Is Nonrenewable Energy?
Non-renewable energy (also known as "non-renewables") comes from resources that we know will eventually run out. In addition, it takes us a very long time to regenerate them. For example, since we use them up as fast as we extract them from the ground, these resources provide electricity, transportation systems, heat, and industries with the goods and services we need for thousands of years.
Some common examples of nonrenewable energy sources include:
Coal
Oil/Petroleum
Natural Gas
Uranium (as a fuel source)
Nuclear energy is non-renewable because uranium is a finite resource that has to be mined. However, unlike coal, oil, and natural gas, nuclear power generates no carbon dioxide during fuel combustion, which is why many still consider nuclear energy as the future of power.
Pros and Cons of Renewable Energy
Renewable energy offers numerous benefits to finite energy resources; however, it also has practical limitations. Understanding the pros and cons of renewable energy will help determine whether a renewable energy source is suitable for your current energy usage, budget, and geographic location.
Pros of Renewable Energy
Key benefits include:
Replenishment is natural
Lowered emission levels during operation
Reduced dependence on fossil fuels
Potential cost savings
Some systems have low maintenance needs
Scales from a small residential solar array to large utility-scale project
Energy independence increased
Cons of Renewable Energy
While renewable energy has several advantages, it does create its own set of challenges. For example, renewable energy technologies such as solar and wind do not always generate at consistent output levels because they rely on natural sources (such as sunlight and wind) that vary by location and time.
As a result, renewable energy often requires energy storage systems to store excess energy generated during times of high resource availability to use when resource availability decreases. High capital expenditures may be required to purchase the necessary hardware to install a renewable energy system. Additionally, finding areas with sufficient resources may be challenging.
Pros and Cons of Nonrenewable Energy
Non-renewable energy is so popular today mainly for three reasons: extensive infrastructure, high energy density, and developed supply chains. Additionally, it is easy to store and distribute. Lastly, many conventional power plants produce power on demand rather than relying on the sun or wind.
Pros of Nonrenewable Energy
Infrastructure for use is already established
High energy density
Reliable, dispatchable generation
Easy to store and transport most fuels
Generation of electricity is unaffected by weather conditions
Existing uses in all areas of transportation, heating, and other industrial applications
As a result of these benefits, it is no surprise that fossil fuels remain an integral part of global energy systems.
Cons of Nonrenewable Energy
There are several cons or drawbacks associated with nonrenewable energy as well. The three main disadvantages consist of:
Limited amounts of each type of nonrenewable energy exist.
Fossil Fuel Combustion produces Greenhouse Gases (GHGs), which contribute to Global Climate Change, as well as Air Pollution.
Damage may occur during the extraction and transport of the fuel.
Fuel prices vary widely at times, leaving users reliant on long, complex supply lines.
In addition, nonrenewable energy will have negative effects over time, including environmental impacts associated with resource extraction and waste management.
What Is the Difference Between Renewable and Nonrenewable Energy?
The main differences between renewable and nonrenewable energy are:
Resource availability
Environmental impacts of resource use
Reliability of the energy source
Costs associated with production or purchase
Infrastructure needed to deliver energy to consumers
Understanding these differences will enhance your ability to determine which energy sources are best for specific applications.
1. Availability of Energy Resources
Resources used in renewable energy production naturally restock over time, such as sunlight, wind, and flowing water. Finite resources used to produce non-renewable energy decrease over time through usage.
Renewable resources can be extensive, but they are not always continuously available everywhere. Weather, geography, and seasonal conditions affect when and where renewable energy is generated.
2. Environmental Impact
Generally, renewable energy produces fewer greenhouse gas emissions than fuel-based fossil-fueled energy during operation. However, burning fossil fuels releases significant amounts of greenhouse gases and air pollutants.
That said, renewable energy technologies do have an environmental impact. Those effects include land use change, changes to habitats, manufacturing impact on the environment, and disruption to ecosystems based on technology location and project scale
3. Reliability and Energy Storage
Fossil fuels can generally be stored for use as needed to support dispatchable generation. Renewable energy production (solar and wind) will vary with time and weather. Storage devices such as batteries or pumped-hydroelectric systems can store surplus renewable electricity for later use. Reliability characteristics of hydropower and geothermal sources can differ from those of variable solar and wind.
4. Cost and Infrastructure
The initial cost of installing renewable energy systems can be high; however, many renewable systems have lower operational costs over their lifetimes. Fossil-fuel-related infrastructure is prevalent across much of the globe and supports existing generation and delivery systems. Renewable adoption will likely require additional transmission infrastructure as well as new or upgraded storage and distribution infrastructure.
How Energy Storage Helps Address Renewable Energy Limitations
Energy storage helps deal with one of the primary challenges of renewable energy: generation does not always occur when electricity is needed. For example, solar panels produce electricity during daylight hours, but households will need more power after sunset. A battery can store excess energy and make it available later.
Energy storage benefits:
Storing solar energy for use at sunset
Providing backup power when renewable generation is temporarily unavailable
Decreasing grid dependence for some applications
Supporting off-grid remote power systems
Assisting in using stored energy when needed by households
The good part about this energy storage is that it makes renewable energy available to the average individual, like with the EcoFlow portable power station.
EcoFlow DELTA 3 Plus Portable Power Station
The EcoFlow DELTA 3 Plus portable power station has a 1 kWh capacity, making it suited to smaller-scale energy storage and portable use rather than for entire-home backup. It could be used for camping, fishing, tailgating, short outdoor trips, or charging smaller items while away from a regular wall outlet. It may also be paired with compatible solar charging equipment to store solar-generated electricity for later use.
EcoFlow DELTA Pro 3 Portable Power Station
The EcoFlow DELTA Pro 3 Portable Power Station provides 4 kWh+ of capacity, making it suitable for substantially larger energy needs than the DELTA 3 Plus. Its higher capacity offers greater flexibility for home power backup, RV use, high-power appliances, extended backup periods, and other larger energy storage needs. Having more stored energy can help support larger loads or keep essential equipment running for longer when grid power is unavailable.
How to Make the Most of Renewable Energy at Home
You will get more out of your renewable energy systems at home if you match your generation and storage to how you actually use electricity. As opposed to looking at just how much energy your entire system is producing, you could look at when you require energy and for how long you are going to require it.
Combine Renewable Generation With Energy Storage
Solar panels provide electricity during daytime hours; however, many households will still have ongoing electrical usage even after the sun has gone down. Batteries can store surplus energy generated by solar panels and make it available later. This can help reduce dependence on utility-provided electricity as conditions allow.
There are several ways that a system can function:
During daylight hours, solar panels produce electricity.
Excess energy produced by solar panels is stored in batteries.
When solar panel production decreases, stored energy can supply power.
Households can rely less on utility-provided electricity under suitable circumstances.
This system addresses the time gap between renewable generation and electricity demand.
Match Your Energy System to Your Needs
Before selecting either a solar or a battery system, consider your average daily electrical usage and which appliances you would like to power with backup power. Factors to consider include:
What essential appliances you have and how much power they require
For how long do you require backup power
What your local solar exposure is
Do you have sufficient space for installation?
What your budget is
Is your primary objective to save money on electricity, maintain backup power for emergencies, or increase your overall energy independence?
Do not assume that a larger Battery or Solar array is always better. What makes a system best suited to your individualized needs depends on your actual electricity consumption, available resources, and your household's personal objectives.
Conclusion
Ultimately, the primary pros of renewable energy resources is their natural replenishment and their typically lower emissions during operation. However, one weakness of renewable energy is that it is often intermittent (e.g., solar and wind are weather-dependent), and there is an issue with storing excess energy when electricity demand is low.
On the other hand, the primary advantage of non-renewable energy is its reliability and controllability. However, this type of energy is limited by the availability of its fuel supplies and generally has a greater environmental impact than renewable energy.
A combination of renewable generation, energy storage options, and appropriate infrastructure will be necessary to develop a flexible, reliable, and sustainable energy supply system.
