10 Disadvantages of Renewable Energy
While renewable energy sources provide the numerous environmental and economic advantages; they also come with significant disadvantages. It’s essential to consider these limitations when getting to evaluate the feasibility and implementation of renewable energy technologies. Here are some common disadvantages of renewable energy, as following them:
Electricity Generation Capacity is Not Enough
Renewable energy sources have the potential to generate electricity without harming the environment. However, one of the main disadvantages of renewable energy is that the electricity generation capacity is still not large enough to meet the rising demand for power.
Due to its intermittent nature of solar and wind energy that needs the backup generating capacity to make ensure a reliable electricity supply.
Despite these challenges, the renewable electricity growth is accelerating faster than ever worldwide, and global renewable electricity capacity is forecast to rise more than 60% from 2020 levels to over 4,800 GW by 2026.
Unreliable Due to Weather Conditions
Renewable energy sources like as wind, solar, and hydropower are totally dependent on weather conditions, including sunlight, wind speed, and the availability of water, making them unreliable.
Extreme weather events like as storms can cause remarkable damage to solar panels and disrupt the supply of renewable energy that is an on-going challenge for the industry.
Although renewable energy can achieve greater levels of reliability by adding energy storage, increasing deployed capacities, or pooling resources of contiguous, multinational regions, the marginal improvements in reliability related to these options differ considerably across countries and regions.
Low Efficiency Levels
Renewable energy sources have lower efficiency levels than non-renewable sources that are one of the main disadvantages of using them. For instance, solar electric generation has a low capacity factor, typically less than 20%, due to the diffuse nature of solar input and its interruption by night and cloud cover.
Wind energy utilization has increased spectacularly in recent years, with annual increases in installed capacity of around 10% to 2019, with tens of thousands of turbines installed. However, all this has to be backed up with dispatch able generating capacity, due to low (20-30%) utilization and intermittency.
Requires Huge Upfront Investment
Renewable energy has to need a huge upfront investment that can be also a significant barrier to its adoption. The reason is that deploying renewable energy technologies requires large up-front investments that must be financed.
The capital’s cost makes up a significant part of the total cost of renewable energy projects. The highly cost of renewable energy is one of the main reasons why many countries continue to rely on non-renewable sources of energy.
However, despite the high upfront costs, renewable energy makes economic sense in the long run. By 2026, global renewable electricity capacity is forecast to rise more than 60% from 2020 levels to over 4,800 GW, equivalent to the current global power capacity from all sources combined.
Intermittency
Intermittency is one of the main disadvantages of renewable energy. Renewable energy sources like as solar and wind that are totally dependent on weather conditions that can limit their use or efficiency.
For instance, solar and wind farms’ energy production can fluctuate between 0 to 23 and 24GW of energy, respectively, during peak times. The unpredictable lulls are what define the intermittency of renewables.
This intermittency is contrasted by the constant power output that can be generated by fossil fuel-based power plants using coal or natural gas, which is often referred to as base-load energy.
Despite the challenges posed by the intermittent nature of renewable energy sources, they are far from insurmountable.
Aesthetic and Environmental Impact
Wind turbines and solar panels can have visual and environmental impacts on local landscapes. Some people find them unattractive or argue that they harm wildlife, especially when poorly sited.
Limited Energy Density
Renewable energy sources tend to have lower energy density compared to fossil fuels. This means that they may require more land or resources to generate the same amount of energy, which can contribute to habitat disruption and resource scarcity.
Energy Conversion Efficiency
The conversion of renewable resources into electricity is not always highly efficient. Solar panels and wind turbines, for example, cannot capture 100% of the available energy from the sun or wind.
Resource Availability
Not all regions have abundant access to renewable energy resources. For instance, regions with limited sunlight or wind may not be as suitable for solar or wind power generation.
Infrastructure and Grid Integration
Integrating renewable energy sources into existing energy grids and infrastructure can be complex and costly. The grid may require upgrades to accommodate variable energy sources and ensure reliability.
