Global Energy crisis Underlines The Need for Renewable Energy Sources

The global energy problem is worsening. According to the Global Energy Review of 2021, energy consumption has increased by 4.5 percent or more than 1000 TWh. This is about five times more than the reduction projected for 2020, putting electricity’s share of total energy consumption beyond 20%.

As demand rises due to the epidemic, there is a lack of supply, and prices are fast-growing. Increased demand for energy infrastructure has been fueled by rising wholesale gas prices, which have rendered utilities unprofitable due to their inability to pass costs on to customers.

At this time, we cannot eliminate any of our current energy sources. They must, however, be adjusted to eliminate or reduce their environmental impact, and new sources of energy, particularly renewable sources, must be provided.


Move Towards Renewable Resources

All sources of energy have an impact on our environment. Each form of energy has its own set of trade-offs, and renewable energy is no different. The advantages of renewable energy over fossil fuels, on the other hand, are undeniable: less water and land use, less air and water pollution, less animal and habitat loss, and decreased greenhouse gas emissions.

To the global energy issue, the greatest potential approach is to strengthen general conservation efforts. For example, fossil fuels were used to power most of the industrial period. Other renewable energy, such as steam, sun, and wind, were also used.

The main issue is not that we will run out of gas or oil, but that the use of coal will continue to harm the atmosphere and deplete other natural resources to the point that it will have to be replaced as a source of energy. As a result, long-term investments in renewables with energy are critical.


Authorities Must Approach It From All Possible Directions

Demand for renewables grew by 3% in 2020 and is set to increase across all key sectors – power, heating, industry, and transport – in 2021. The electric power industry is pushing ahead, with renewable energy demand projected to increase by more than 8% to 8 300 TWh, one of most year-on-year growth in absolute terms recorded.

However, at this moment, the most pressing problem may be to push renewable energy to become a large portion of the overall supply. There hasn’t been a miracle that will instantaneously address the challenge of delivering power to humanity. It must be handled from all angles, not just technologically because political and economic factors are equally important for each potential energy source.

Solution? Investment In Clean Energy

Supply disruptions and energy crises will become more likely as climate consequences deepen. Diversifying away from fossil supply chains and moving towards renewable energy can help mitigate the effects. Renewable sources provide greater independence from volatile fuel supply chains, particularly in the long run as their percentage of generation increases and energy storage and cleaner energy.

The human toll will be devastating, particularly in the nations severely impacted by COVID-19. Some may argue that increasing gas output is the solution but blaming renewable energy and climate action will be misdirected. Instead, the crisis highlights the need to invest in clean energy resources, such as solar, wind, batteries, and advanced nuclear, geothermal, and other technologies, to sustain a clean power grid that is less vulnerable to unpredictable manipulable fuel supply chains.
